Sound familiar?

You don’t need more headcount. You need senior engineers who have shipped this before.

  • Engineering velocity stalling

    Every release risks breaking three other things. The legacy module no one wants to touch is now the legacy half of the product.

  • AI demos that won’t ship

    A copilot works in the sandbox, but cost spikes, hallucinations, and missing fallbacks block the production rollout.

  • Operational drag on senior time

    Manual support tickets, scattered internal docs, and brittle workflows are pulling your senior team away from product work.

Built for founders who plan to be here in five years

Three things every client gets, by default — from the first kickoff call to year three of the partnership.

AI-native

Designed in from day one

AI capabilities are part of the product design from the first discovery call — streaming experiences, evaluation harnesses, cost guardrails, and fallback paths treated as production engineering.

4–6 weeks

From discovery to live product

We deliver a working product on your own domain in 4 to 6 weeks. Weekly demos, real users, real feedback — no quarter-long wait for something you can actually use.

Multi-year

Partnership beyond launch

Many engagements continue for years. Monthly retainer support, ongoing roadmap work, and the same team that shipped your product still knows it two years later.

What we bring

The defaults you would write into a contract — already in our work

Six things that separate a developer who built it once from an engineer who will keep running it with you. If you have ever had to clean up after the first one, you will recognise the list.

AI integration, done thoughtfully

We treat large language models as production dependencies — with streaming UIs, eval suites, cached responses, fallback paths, and clear cost limits. Designed to age gracefully, not to break next quarter.

Working build in 4 to 6 weeks

From the first discovery call to a live, useful product on your own domain. Weekly demos on staging with real data, so you always have a working product to share with users, investors, or the board.

Quality your team can audit

Typed APIs, structured logs, traces, and tests where they actually catch bugs. The patterns reviewers, auditors, and future acquirers expect to see.

Code your future hire can grow into

Documented, conventionally structured, with runbooks. A new engineer becomes productive in days, not quarters — and the codebase reads as well in two years as it does today.

A partnership beyond launch

Most engagements continue with monthly retainer support, ongoing roadmap work, and on-call response when something breaks. The same senior team, year after year.

Direct access to engineers

The person on your kickoff call writes the code. No account managers in the middle, no rotating contractors, no junior placeholders disguised as seniors.

None of this is exotic. It is the difference between code that ships once and code your team can keep building on for years.

Recommendations

What founders and product leaders tell us most often after an engagement wraps up.

  • We hired LaunchStacks for the MVP and stayed on for the next two years. Honest scoping, clean code, and the same senior engineers throughout — exactly what we needed before we could afford to hire in-house.

    Founder

    Early-stage B2B SaaS

  • They explained tradeoffs in plain English and shipped weekly demos we could share with the board. The MVP was not a throwaway — it became the foundation we have grown on for the past eighteen months.

    Product lead

    Seed-stage team

  • Async updates we could forward straight to investors, weekly demos on a real staging domain, and ongoing support long after launch. The kind of engineering partnership we couldn’t find anywhere else.
