  • Production-grade software
  • You own the code
End-to-end We own the solution from the first conversation through to production and beyond.
Senior team Experienced people on every project — no juniors learning on your dime.
Outcome-focused We measure success by shipped, reliable software that earns its keep.
You own it The code, infrastructure, and IP are yours — no lock-in, no black box.

What we do

What we build — and proof we've done it.

Two focused practices, each backed by real work our team delivered in senior roles for other companies. Clients are under NDA; the experience is what we bring to you.

AI Agents & Automation

AI assistants and agentic workflows that automate real work — designed for reliability and built on cloud infrastructure that runs them at scale.

Proven An AI agent management & runtime platform on AWS Bedrock AgentCore, serving 2,500+ users

Mobile Applications

Native and cross-platform apps built for performance and longevity — including connected-hardware and Bluetooth device experiences.

Proven A connected-hardware app shipped to 100,000+ users

Our approach

A partner that owns the outcome.

We don't hand over a pile of code and walk away. We take responsibility for the whole solution — understanding the business problem, designing the right system, and delivering it to production at the quality our clients expect.

Our team has built and shipped software used at real scale, and we bring that experience to your project — with everything we build yours to keep, no lock-in and no black box.

  • We own delivery

    From the first conversation to production, the outcome is our responsibility — not a checklist of tasks.

  • Senior by default

    Every engagement is led by people who have already solved hard problems in production.

  • Yours to keep

    We don't lock you in — the code, infrastructure, and IP are all yours from day one.

About us

A solutions partner you can trust.

Chestnut Street Labs is a software solutions partner. We're a focused team that would rather deliver a few things exceptionally well than spread ourselves thin — and we treat every client's project as our own.

We work with founders and businesses across the United States and Europe who need serious software built and delivered — quickly, reliably, and without the risk of an unproven team.

“We don't sell hours or headcount. We deliver solutions our clients can build a business on.”
