One Hundred MVP
A 100-day MVP development and validation program.Build a working product, test it with customers, and decide what comes next.
Sound familiar?
Common walls funded startups hit after raising capital
Funding secured, but development is stalled
You've raised from VCs but lack the technical execution power to move forward.
Can't hire a CTO or engineers fast enough
Recruiting product-building talent takes too long for your startup's pace.
Outsourcing fails on quality and speed
Agency work lacks business context, and every change request inflates cost and time.
Struggling to show investor progress
Without a clear development roadmap, you can't demonstrate milestones for the next round.
Forward Deployed Engineering is the answer
Not outsourcing. Not hiring. A third option. An engineering team that deeply understands your business joins your team directly to build your product together.

Development Process
AI agents accelerate implementation while humans focus on decisions and quality review
Weekly cadence, immediate feedback
Requirements are structured from weekly meetings, voice memos, and chat, then reflected in development right away — decisions become working screens by the next week.
Three quality gates
Humans review requirements & UI/UX, data & feature design, and implementation PRs. Aligning upstream prevents the classic "it's wrong once it's built" rework.
AI multi-agent development
Dedicated AI agents run requirements, design, TDD implementation, review, and E2E verification in parallel — automating tests to deliver both speed and quality.
