Senior product development
across the full stack.
Every engagement at Leavingstone is led by a senior specialist. We don't add juniors to scale — we heavily adopt AI.
Two engagement models. One operating standard.
A defined entry point for validating direction, and a standing team to deliver against it. Both led by senior practitioners.
01 — Discovery Engagement
Four to six weeks. Fixed scope, fixed price.
A structured engagement that produces product strategy, UX direction, and an architectural recommendation. The output is a working plan — not a pitch deck.
From $15K — $25K
02 — Agile Product Team
Embedded, multi-disciplinary, senior.
A standing team of product, design, and engineering operating inside your roadmap, your tools, and your governance.
From $20K / month
