How this works

One AI-native engineer.
The output of a team.

One senior engineer plus AI agents now ships mobile app development that used to need a four-person team. Same code quality, half the cost, three-week timelines instead of three months. Built for pre-seed to Series A founders in Boston who need to ship before the next round closes.

The local read

Why mobile app development is hard in Boston

Boston founders have access to the best deep-tech talent in the country and almost none of it is hireable at seed stage. Biotechs pay above market for ML engineers. Cambridge robotics shops pay close to that for ROS 2 specialists. The local agency option is mostly enterprise consulting with multi-quarter contracts.

We're not enterprise consulting. One senior engineer owns the build, Eastern Time, overlap with your MIT advisors and Boston-based investors. FHIR or HL7 for healthtech. PyTorch and Hugging Face for ML features. Next.js for the SaaS layer. Flat-price quote in 24 hours. Code in your GitHub from commit one.

Boston's accelerator infrastructure is some of the deepest in the country — MassChallenge (equity-free, HQ'd here since 2009), Techstars Boston (the network's second-oldest program) and Greentown Labs in Somerville, which still houses about 125 climate-tech startups. Early-stage capital comes from General Catalyst, NextView Ventures, Pillar VC and Flybridge. The Massachusetts biopharma sector alone raised $6.85B across 197 rounds in 2025 — 26.2% of all national biopharma VC, second only to California — and for the second year running, the city of Boston itself out-raised Cambridge, with 71% of funding going to companies outside the MIT/Harvard core. Harvard Innovation Labs has backed 6,500+ ventures that have collectively raised more than $9B, including WHOOP and Rapid SOS. That academic pipeline is exactly why ML and biotech engineers here are priced against research-lab and biopharma offers most seed-stage budgets can't touch.

Boston's biopharma comeback accelerated hard in 2026: Massachusetts biopharma companies raised $3.45B in VC in the first half of the year alone, up 25% year-over-year and the strongest opening half since 2023, and eight Massachusetts biopharma companies went public in that same half — matching the combined 2024-and-2025 total. On the software side, Underscore VC runs a $140M fund exclusively for earliest-stage companies based in or moving to Boston, while MassRobotics just picked its second accelerator cohort — 10 startups out of 130+ applicants, each getting a $100K non-dilutive grant. Local employers are hiring into this too: Klaviyo, headquartered in the Seaport, posted 46.5% more job listings in 2026 than the year before. Good news if you're trying to build a network here — expensive news if you're trying to hire against it.

Boston's sector mix leans Healthtech — the kind of ground where mobile app development work shows up on our desk most often here.

Hiring one senior engineer here is a ~$290K year-one outlay and a 60–90 day search. Our mobile app development engagement starts at $5,000 with a first deploy in 3–6 weeks to TestFlight.

FAQ

Common questions about mobile app development in Boston

How fast can you start?

+
Most builds begin within seven days of the first call. We don't sell discovery — we go from problem statement to first deploy on the same day-one timeline.

Is the price really flat?

+
Yes. After a 30-minute call we send a single number and a scope you can accept or reject. No hourly billing, no change-order games. If we underestimate, we eat it.

React Native or native (Swift/Kotlin)?

+
React Native by default — 90% of features are identical and you ship to both stores at once. Native if you have hard requirements (live activities, complex camera, low-level audio, watch app).

Do you handle App Store submission?

+
Yes — Apple Developer + Google Play account setup (or working in yours), screenshots, privacy declarations, review responses if rejected. Most apps clear review in 24–72 hours.

Who owns the code?

+
You do, from commit one. The repository is created in your GitHub org. Infrastructure is provisioned in your cloud account. We don't host your stack on ours and we don't lock you in.
