If you're looking for a team to build your mobile app, there are a lot of great options to choose from. The hard part is figuring out which one is right for your specific situation.
There's no single "best" option.
The right one depends on what you're building, your budget, and how much of the product you want to run yourself.
For example, a 1,000-person enterprise firm will overbuild a founder's lean MVP. And a cheap offshore dev shop isn’t going to be a good fit for a regulated healthcare app.
So we pulled together 28 of the strongest options and broke down what each team does, who they're a good fit for, and what they cost - so you can find the one that fits what you need.
1. Studio
Studio is a New York product studio that works with you like a co-founder would. Design, engineering, and product strategy all live under one roof. And we own the roadmap from idea to launch, and ongoing iteration. We're a good option for startup founders who've raised funding and enterprise teams who want to move fast with a senior team with experience shipping consumer-grade mobile apps at scale. Hiring that team yourself can take a lot of time and money, and even then, a new team might not work well together. Our team allows you to get to market and hit your goals faster and more reliably.
- Focus: Consumer and enterprise digital products, mobile-first, product strategy
- Services: Product strategy, branding, UX/UI, native iOS & Android, web, backend, AR/Vision Pro, AI
- Pricing: $$$ · custom, scoped per project (MVP to enterprise)
- Proof: Built Lovelle (live-shopping for QVC), Black Rifle Coffee, Mustard, and Creatively
Studio is a premium, US-based option, so you'll pay more than you would for an offshore or staff augmentation team. But you'll get a premium partner who can own your product roadmap and drive results for you.
2. WillowTree (now TELUS Digital)
WillowTree is one of the most decorated app studios in the US, now inside TELUS Digital after a $1.2B acquisition, pairing consumer-grade design with enterprise security and scale. It's a great fit for big brands and enterprises shipping a flagship app where polish can't slip. It's overkill on an MVP budget, and you're now hiring an enterprise-scale org, not a boutique.
- Focus: Flagship consumer apps, enterprise UX, product strategy
- Services: Native iOS & Android, cross-platform, UX/UI, product strategy, AI/data engineering
- Pricing: $$$ · $100–149/hr ($50K+ min)
- Proof: ~1,000 people, since 2008 · 600+ clients, near-perfect Clutch rating
The minimums are steep, but for a make-or-break consumer app, that buys one of the most proven teams around.
3. Fueled
Fueled is a premium New York agency that made its name on beautifully designed consumer apps, including Warby Parker's. It's a great fit if your app is a brand-and-design statement and you have the budget to match. It's less of a fit if you're on a tighter budget or building something simple.
- Focus: Design-forward consumer apps, brand experience
- Services: Native & cross-platform, UX/UI, product strategy, branding, web
- Pricing: $$$ · $150–199/hr (~$75K min)
- Proof: Since 2007 · built Warby Parker's app (an Apple Best of 2016 pick) and the Barneys app (a Webby honoree)
Fueled isn't cheap, but if design is what will make or break your app, that's exactly where the money goes.
4. Utility
Utility is a New York product studio built around research and strategy, with a client list most boutiques can't claim. It's a great fit if you're a funded startup or brand standing up a flagship product and want the thinking behind it, not just the build. It's less of a fit if you just need a simple, low-budget build.
- Focus: Research-led product, brand and enterprise flagship apps
- Services: Product strategy, user research, UX/UI, native & cross-platform development
- Pricing: $$$ · $100–149/hr ($50K+ min)
- Proof: Clutch 4.8/26 · since 2013 · shipped apps for Airbnb and the NBA
The high pricing and minimums are what fund the deep research and strategy most shops skip.
5. ArcTouch
ArcTouch is a San Francisco product studio founded by ex-Apple veterans, now part of WPP's AKQA network, shipping polished consumer and connected-device apps since the App Store opened. It's a great fit if your product has a hardware, IoT, or connected component and you want real design craft behind it. It's less of a fit if you want an independent boutique or a budget build.
- Focus: Consumer apps, IoT / connected devices, cross-screen (phone, TV, voice)
- Services: Product strategy, UX/UI, native & cross-platform, IoT, AR, voice, QA
- Pricing: $$$ · $50–99/hr nearshore ($100K+ min)
- Proof: ~350 people, since 2008 · 1B+ downloads across its apps
It's owned by WPP, and projects start at a high minimum.
6. thoughtbot
thoughtbot is an independent product and engineering consultancy that's been a fixture of the Rails and open-source world since 2003. It's a great fit if you want senior engineers who ship well-tested code and leave you with low technical debt. It's less of a fit if you want a pure design-brand studio, or if budget is your main concern.
- Focus: Engineering-led product, startups, code quality
- Services: Product strategy, UX/UI, native (Swift/Kotlin) & React Native, web, ongoing support
- Pricing: $$$ · premium senior rates
- Proof: 20+ years independent · open-source pillar in the Rails world, with clients like GitHub and Etsy
You're paying senior-consultancy rates, and the return is engineering you won't be rewriting a year from now.
7. EPAM Systems
EPAM is a 60,000-person global engineering giant, one of the largest pure software-engineering firms in the world. It's the right call for large, sustained enterprise programs that need deep delivery muscle for years. For an MVP, it's far more scale (and cost) than you need.
- Focus: Enterprise platform engineering, cloud, AI/digital transformation
- Services: Custom software, mobile, cloud, data/AI, modernization, consulting
- Pricing: $$$ · enterprise-tier (well above $100/hr)
- Proof: ~60,000 people · FY2024 revenue $4.7B · NYSE-listed since 1993
With 60,000 engineers, EPAM can staff almost any program, which is why it's geared to enterprise budgets and timelines.
8. Thoughtworks
Thoughtworks is the consultancy that helped write the book on agile and continuous delivery, and it still sets the bar for engineering rigor at enterprise scale. It's a great fit if you're a large organization modernizing a complex platform and care how the work is done, not just what ships. It's less of a fit if you want a small, design-led boutique.
- Focus: Complex enterprise modernization, engineering culture, agile transformation
- Services: Custom software/product engineering, mobile, platform engineering, consulting
- Pricing: $$$ · enterprise-tier
- Proof: Forrester Wave Leader (Modern App Dev, Q1 2025) · ~11,000 staff · founded 1993
Thoughtworks brings serious engineering discipline, and you engage it like the enterprise consultancy it is, with the process and budget that implies.
9. Globant
Globant is a 29,000-person, Latin-America-rooted digital and AI transformation firm with marquee, decade-long relationships. It's a great fit if you're a global enterprise wanting AI-infused transformation at scale. It's less of a fit if you want a mobile-first boutique, since the firm has reoriented hard around AI.
- Focus: AI transformation, digital experience, media/entertainment, nearshore-at-scale
- Services: Custom software, mobile, AI ("AI Pods"), cloud, data, design
- Pricing: $$$ · enterprise-tier
- Proof: ~29,000 staff · NYSE-listed · decade-long work with Disney and Google
At around 29,000 people, Globant works at the scale of a global rollout, with the enterprise engagement model to match.
10. BairesDev
BairesDev is the dominant nearshore firm in Latin America, fielding thousands of vetted senior engineers in US time zones. It's a great fit if you need to scale an engineering team fast without the offshore time-zone gap. It's less of a fit if you want one team to own product strategy and design, since this is staff augmentation, not a turnkey studio.
- Focus: Team scaling, senior engineering talent, custom software
- Services: Dedicated teams, staff augmentation, mobile, AI, cloud, data, DevOps
- Pricing: $$ · $50–99/hr ($50K+ min)
- Proof: Clutch 4.9/63 · ~4,000 engineers, ~$800M revenue · a Harvard Business School case study
This is staff augmentation, so you bring the product direction and they bring vetted senior engineers, fast.
11. Netguru
Netguru is a Polish studio and certified B Corp known for design-led product work, with verifiable enterprise clients. It's a great fit if you want European design craft and enterprise credibility at mid-market rates. It's less of a fit if you need all-day US time-zone overlap.
- Focus: Design-led product, fintech, AI, enterprise
- Services: Product/UX design, native & cross-platform, web, AI, staff augmentation
- Pricing: $$ · $50–99/hr ($50K+ min)
- Proof: Clutch 4.8/73 · certified B Corp · built the Citi Bike app
It's EU-based, so expect limited all-day US time-zone overlap.
12. 10Pearls
10Pearls is a Washington-area digital engineering firm with a 1,000-plus-person bench across Latin America and Pakistan and real Fortune-500 work. It's a great fit if you're an enterprise or funded scale-up that wants deep engineering capacity without full-offshore distance. It's less of a fit if you want a small US-staffed boutique.
- Focus: Enterprise digital engineering, healthcare, fintech, AI
- Services: Mobile, web, product design, cloud, cybersecurity, digital transformation
- Pricing: $$ · $25–49/hr (~$10K+ min), enterprise quality at a value rate
- Proof: Clutch 4.9/36 · 1,000+ people, since 2004 · 7× Inc. 5000 · built for AARP
Its team is offshore, but the Latin America base keeps a good part of the day on US hours.
13. Appinventiv
Appinventiv is a large app development firm in Noida, India, that scaled fast building consumer apps for big global brands. It's a strong fit if you want brand-grade delivery at offshore rates and have enough product direction in-house to steer an overseas team. It's less ideal if you need on-site US collaboration or all-day time-zone overlap.
- Focus: Consumer apps at scale, fintech, enterprise, AI
- Services: Strategy, design, native & cross-platform, backend, AI/ML, blockchain
- Pricing: $$ · $25–49/hr ($50K+ min)
- Proof: Clutch 4.6/90 · ~1,500 people, since 2015 · 3,000+ apps shipped (KFC, Adidas)
It's a large offshore vendor, so define your scope and the assigned team clearly up front.
14. TechAhead
TechAhead is a mobile-first firm with a California front office and India delivery, and, unusually for its tier, real security credentials. It's a great fit if you want a US point of contact and offshore economics on a build that takes security seriously.
- Focus: Mobile-first builds, AI, cloud-native, security-conscious delivery
- Services: iOS/Android, React Native, Flutter, AI, cloud, QA
- Pricing: $$ · $25–49/hr ($25K min)
- Proof: Clutch 4.9/121 · since 2009 · SOC 2 Type II + ISO 42001
The front office is US-based but delivery is in India, so plan for some time-zone coordination.
15. Simform
Simform is a 1,000-plus-person firm (Orlando HQ, India delivery) that's strongest on cloud-native, data, and AI engineering, not just the mobile front end. It's a great fit if your product is backend- or cloud-heavy and you want an AWS/Azure-grade partner at mid-market rates. It's a lighter fit if you just need a simple front-end-only app.
- Focus: Cloud-native, data engineering, AI/ML, backend-heavy products
- Services: Mobile, cloud/DevOps (AWS/Azure), data engineering, AI/ML, co-engineering
- Pricing: $$ · $25–49/hr ($25K+ min)
- Proof: Clutch 4.8/85 · 1,000+ people, since 2010 · AWS/Azure partner · Clutch 1000 (2023)
Delivery is India-based behind a US HQ, so plan for time-zone coordination.
16. GeekyAnts
GeekyAnts is a Bangalore firm with a hard-earned cross-platform reputation: it authors and maintains NativeBase and gluestack-ui, two of the most-used React Native UI libraries. It's the clear fit if you're committed to React Native or Flutter and want the framework's own experts. Expect a roughly 12-hour time-zone gap.
- Focus: React Native / Flutter, cross-platform, product consulting, AI
- Services: Web & mobile development, product/design consulting, AI, DevOps, QA
- Pricing: $$ · $25–49/hr ($10K+ min)
- Proof: Clutch 4.8/115 · authors NativeBase and gluestack-ui, two widely used React Native UI libraries
There's a roughly 12.5-hour time-zone gap to plan around.
17. Designli
Designli is a Greenville, South Carolina studio built specifically for non-technical founders, assigning a full product team to each build. It's the best fit if you have an idea and need a partner to hold your hand from concept to launch. It's less of a fit if you want offshore rates, since it's a US team.
- Focus: Non-technical founders, MVPs, idea-to-launch
- Services: "SolutionLab" discovery, UX/UI, MVP, native & React Native, web
- Pricing: $$ · $50–99/hr ($10K+ min)
- Proof: Clutch 5.0/79 · since 2013 · #1 app developer in South Carolina (Clutch)
Rates run above offshore, but you get a dedicated US team with no time-zone gap to manage.
18. Saritasa
Saritasa is a Newport Beach firm that does AR, VR, IoT, and complex custom systems under one roof, backed by the deepest review base of any specialist here. It's a great fit if your build is immersive, connected, or integration-heavy and you want hardware-to-software breadth. It's less of a fit for a small, simple MVP, given the minimums.
- Focus: AR/VR, IoT, complex custom systems, integrations
- Services: Strategy, design, native & cross-platform, AR/VR, IoT, custom software, DevOps
- Pricing: $$$ · $100–149/hr ($50K+ min)
- Proof: Clutch 4.8/106, the deepest review base of any specialist on this list
You'll pay US rates, but Saritasa backs them with the deepest review record of any specialist on this list.
19. Chop Dawg
Chop Dawg pitches itself as your outsourced product team, with a famously transparent process (daily Slack, weekly calls, shared Jira) and 500+ launches. It's a great fit if you're a founder who wants a partnership-style process on a budget.
- Focus: Founder/early-stage builds, transparent process
- Services: Native iOS & Android (incl. wearable, CarPlay), web/eCommerce, UI/UX
- Pricing: $$ · $50–99/hr, low floor · transparent fixed-monthly model
- Proof: Clutch 4.8/107 · since 2009 · 500+ launches
Its transparent, fixed-monthly model is easy on an early-stage budget, as long as your scope stays focused.
20. CitrusBits
CitrusBits is a Los Angeles boutique that's shipped 300+ apps with a real specialty in AR and immersive consumer experiences. It's a great fit if you want a polished consumer app with an AR or interactive twist from a nimble, design-forward team.
- Focus: AR/immersive, consumer apps, UX-led design
- Services: Product strategy, UX/UI, native & cross-platform, AR
- Pricing: $$$ · $100–149/hr ($50K+ min)
- Proof: Clutch 5.0/36 · since 2005 · 300+ apps shipped, AR/immersive specialty
As a boutique, it shines on focused consumer and AR builds, and a sprawling, company-wide program would stretch it.
21. Mercury Development
Mercury Development is a Miami firm that's been building custom software since 1999, with deep QA and real regulated-domain work. It's a great fit for long-haul, quality-sensitive builds, especially regulated or hardware-adjacent products.
- Focus: Regulated and hardware-adjacent products, QA-heavy delivery
- Services: Native & cross-platform, custom software, ML, IoT, DevOps, QA
- Pricing: $$ · $50–99/hr ($25K+ min)
- Proof: Clutch 5.0/33 · since 1999 · 2,500+ projects (Henry Ford Health, Dow Chemical)
Mercury optimizes for durable, well-tested software, which pays off most on long-lived or regulated products.
22. Cheesecake Labs
Cheesecake Labs pairs Silicon Valley product thinking with a Brazil-based engineering team, so you get premium quality at nearshore cost on Americas time. It's a great fit if you're a startup or mid-market team that wants senior product and design pods without US-boutique rates. It's less of a fit if you require an all-US, on-site team.
- Focus: Product + design pods, AI, blockchain/Web3, AR/IoT
- Services: Product strategy, UX/UI, native & cross-platform, backend
- Pricing: $$ · $50–99/hr ($50K+ min)
- Proof: Clutch 4.9/64 · since 2013 · ranked #7 globally for mobile and web app development (Clutch 2025)
Delivery is Brazil-based, which keeps the team on US-friendly hours at nearshore rates.
23. Binary Studio
Binary Studio is a Ukrainian engineering boutique with its own selective talent academy and a reputation for low-defect code. It's a great fit if you want a small, senior engineering team rather than a body shop or a design agency.
- Focus: Senior product engineering, dedicated teams
- Services: Native & cross-platform, full-cycle delivery, dedicated teams, maintenance
- Pricing: $$ · $50–99/hr ($25K+ min)
- Proof: Clutch 4.9/56 · since 2005 · selective in-house "Binary Studio Academy" talent pipeline
It's sized for focused, senior teams, so a small, well-built product plays right to its strengths.
24. MindSea
MindSea is a Halifax studio that specializes in healthcare, baking HIPAA and Canadian privacy rules in from day one. It's the best fit if you're building a digital-health or research-grade app, especially anything crossing the US/Canada border. It's not the fit if you're outside healthcare or working to a tight budget.
- Focus: Digital health, HIPAA + Canadian privacy (PHIPA), research-grade apps
- Services: Product strategy ("Blueprint" discovery), UX/UI, native & cross-platform, post-launch support
- Pricing: $$$ · $150–199/hr ($10K+ min)
- Proof: Clutch 5.0/41 · since 2007 · healthcare-focused (University Health Network, Sunnybrook)
For a health app, baking HIPAA and privacy in from day one is worth the premium, as long as you confirm capacity for a tight timeline.
25. Topflight Apps
Topflight is a boutique specializing in healthtech and biotech, with a track record of apps that raise money and run clinical trials. It's a great fit if you're a venture-backed health startup that needs to fundraise and run studies on the same app.
- Focus: Healthtech, biotech, clinical trials, fundraising-stage products
- Services: Product strategy, UX/UI, full-stack engineering
- Pricing: $$$ · $100–149/hr ($50K+ min)
- Proof: Clutch 4.9/42 · the apps it's built have raised $200M+ · powered Merck & Stanford trials via Medable
It's a small, specialized team, which is the point if you want deep healthtech expertise, and less of a fit if you need a large general-purpose shop.
26. ScienceSoft
ScienceSoft is a 37-year-old Texas firm built for regulated work, and one of the very few app shops carrying ISO 13485, the medical-device quality standard. It's the right call for compliance-heavy builds, especially software-as-a-medical-device and fintech. It's not the fit for a design-first consumer app or a quick, lightweight MVP.
- Focus: Regulated industries: healthcare (HIPAA), fintech, software-as-a-medical-device
- Services: Custom software, mobile, healthcare IT, AI/ML, QA, cybersecurity
- Pricing: $$ · $50–99/hr
- Proof: Clutch 4.8/42 · since 1989 · ISO 9001 / 27001 / 13485 certified
Its real value is the compliance credentials, like medical-device certification, that design-first shops don't carry.
27. 3 Sided Cube
3 Sided Cube is a UK studio that works in "tech for good," building apps for organizations like the American Red Cross and UNHCR. It owns a lane nobody else here touches, so it's the obvious fit for nonprofits, NGOs, and purpose-driven brands.
- Focus: Nonprofits, NGOs, humanitarian and purpose-driven apps
- Services: Product scoping, UX/design, build & launch, ongoing support
- Pricing: $$$ · $100–149/hr ($50K+ min)
- Proof: Clutch 4.9/49 · American Red Cross, UNHCR, UNESCO
It's one of the few studios genuinely built around mission-driven work, and you'll pay premium rates for that focus.
28. Goji Labs
Goji Labs is a Los Angeles product studio with a strong reputation for helping startups and non-technical founders build and launch their first product. It's a great fit if you want a collaborative US partner to shape and build your first product. It's less of a fit if you're after offshore rates, since it's a US team.
- Focus: Startups, non-technical founders, product strategy, MVPs
- Services: Product strategy, UX/UI, mobile & web development, MVP
- Pricing: $$ · $100–149/hr ($25K+ min)
- Proof: Clutch 5.0/84 · since 2014 · 500+ products launched
You'll pay US rates, but the trade is all-day collaboration and a studio that's launched 500-plus products.
How Do You Choose the Right One for You?
Narrowing down to the right team mostly comes down to understanding what you need, and what your budget and goals are:
- What stage are you, and what's the budget? For example, a non-technical founder validating an idea needs a team that will shape the product, not a 60,000-person firm that bills by the quarter. An enterprise modernizing a platform needs depth of talent that a four-person boutique can't staff. Make sure you work with a team that can match your needs.
- What's the hard part of your app? Every shop here can build a screen. The question is - what does your product actually live and die on? A regulated healthcare app needs HIPAA compliance and audit trails. A consumer app needs high quality design and to hit consumer retention benchmarks. For a data or AI-heavy product, backend engineering becomes a bigger risk. Pick the team whose core competency aligns with the most important part of your product.
- How much do you want to run yourself? This is the one most people tend to skip. Staff-augmentation firms hand you excellent senior engineers, but you're still the product owner. You need to set the direction, you need to catch the mistakes. A full-service studio takes that weight off you and owns the outcome. Neither is better, but hiring the wrong one for your situation is one of the most common way these kinds of projects go sideways.
Picking the Right Team for Your Situation
There's no universal winner here. The best mobile dev team is the one that fits your problem, your budget, and how much of the product you want to own yourself.
If you've raised money and want to move fast, or you're a larger company launching a new product line - hiring a product and engineering team is slow and risky. And a team that doesn't gel can cost you months (or years) of wasted effort. Studio is the plug-and-play alternative: a senior team that's already worked together and shipped products at scale, ready to own strategy, design, and engineering with you from day one.
If that sounds like what you're after, we'd love to chat. Book a call and tell us what you're building, and if it turns out we're not the right fit, we'll gladly point you to someone on this list who is.
