Shapes representing product design phases

Adoption Sprint

Your product works. But users still need too much help to get value from it.
How it works:
  • A free adoption audit first. I map where your flow breaks before either of us commits
  • 4 week sprint, fixed scope and fixed price, locked after week 1
  • A working prototype in code you can test, with states and edge cases
  • Source files, system, and documentation ready for your team to ship

Your product keeps evolving. I work with your team as an ongoing senior product design partner.
How it works:
  • Flexible monthly capacity with the flexibility to focus on whatever matters most
  • From early product thinking and UX through polished UI and production ready designs
  • I work directly with founders and product teams, without extra layers or handoffs
  • Stay for as long as you need, and adjust the engagement as your product and priorities change
