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 Seattle who need to ship before the next round closes.

The local read

Why mobile app development is hard in Seattle

Seattle founders have access to deep technical talent that's mostly busy. The candidates who do interview want AWS comp, or are leaving to start their own thing. Either way, your 90-day hiring cycle becomes 180.

Different math: one named senior engineer plus AI agents, Pacific Time, ships in two weeks. Flat-price quote after a 30-minute call. AWS-native by default — Bedrock, Lambda, DynamoDB, S3 — same stack your team already runs. Code in your GitHub from commit one. Walk away clean at the end.

Seattle's startup infrastructure runs through Techstars Seattle (alumni have raised over $1B post-graduation) and Pioneer Square Labs, backed by Madrona Venture Group — the Pacific Northwest's anchor fund, currently investing out of a $300M Fund VII — plus newer entrants like Founders' Co-op and the $50M Fortson VC fund launched in 2025. The talent density backs it up: CBRE's Scoring Tech Talent report ranked Seattle #2 in North America for tech talent two years running, behind only the Bay Area, with the Puget Sound region adding nearly 25,000 tech jobs between 2022 and 2025. AI is pulling its share too — local AI startups alone raised $679M in the first eight months of 2025. None of that changes the math for a seed-stage founder: Amazon and Microsoft set the local salary floor, and neither is going anywhere.

Seattle's 2025-2026 story is really about churn, not just growth: Amazon cut roughly 14,000 corporate jobs in October 2025, then another 16,000 or so about three months later; Microsoft has cut 15,000+ jobs globally since May 2025, including over 3,200 in Washington state alone. That's a lot of senior engineering talent hitting the market at once — talent that trained at places like the University of Washington's Allen School, tied for #7 nationally in graduate CS with average starting salaries around $110K. On the funding side, Madrona runs Create33, a dedicated founder hub a floor below its own office, and Flying Fish Partners writes $500K-$1.5M pre-seed and seed checks exclusively into AI and ML infrastructure. The city isn't short on engineers right now — it's short on companies moving fast enough to hire them before Amazon or Microsoft does again.

Ask what Seattle builds and the honest answer is AI and ML infrastructure and Cloud tools — which is exactly the terrain mobile app development work has to hold up in.

Hiring one senior engineer here is a ~$310K 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 Seattle

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.
