What we make

Assay Builds is a boutique studio for companies whose business has outgrown the brand and the software carrying it. We write the positioning. We build the identity, the type, and the design system. We ship the marketing site and the product underneath — and we stay on long enough for the new foundation to be load-bearing.

No handoffs between strategy, design, and engineering — because there aren't three teams. There's one. Seven days, kickoff to launch. Fixed fee, not an estimate range. You keep the client-specific assets, repos, seats, and handoff inventory in the signed scope.

We take on three builds per quarter. If the business is real and the team is ready to ship rather than shop, tell us about it.

The week No black boxes. One senior team. Every day a live deliverable.
Day 01
We audit.
Brand, tech, positioning. Scope agreed before a pixel moves.
Days 02–03
We design.
Identity, tokens, type, components, the design system.
Days 04–05
We build.
Marketing site and the software beneath. Previews on every commit.
Days 06–07
We ship.
Domain, analytics, monitoring. Two weeks of light handoff support baked in.

For companies operating ahead of how they currently show up.

The fit

Founder-led and operator-led. Post-traction, pre-bloat — somewhere between Seed and Series C. Real revenue. A business the team is proud of and a website that stopped matching it two raises ago.

The posture

Serious about the work. We build for teams that care about craft and want the rebuild to reflect what they actually do — not a category template, not a moodboard, not a deck. Ready to ship, not shop.
