05 / 06 Method Concept → customer

How a product moves.

05.01 · Concept
Start with a narrow technical wedge
One problem, one surface, one user. If it can't be explained in one sentence, it's too broad.
PopLayer started as: "publishers can't get paid without spreadsheets"
05.02 · Build
Ship the real system, not a shell
Schema, backend, surface, deploy pipeline. Working code on real infrastructure from day one.
Emban: Go backend + ClickHouse + React dashboard in one binary
05.03 · Harden
Docs, auth, tests, operations
Everything it takes to run in production. JWT sessions, rate limiting, monitoring, deploy automation.
PopLayer: isolated signing host, 4 fraud providers, Redis Sentinel HA
05.04 · Launch
Something a customer can evaluate
Live URL, real data, working product. Not a demo — a system someone can depend on.

Two fixed-scope shapes. Both end in shipped code.

Wedge
Ship Recommended
Duration 2 weeks 6 weeks
Price From €8k · fixed From €28k · fixed
Deliverable One narrow surface: embed, console, billing flow, or self-hosted path Full track: schema, backend, surface, docs, auth, deploy
Outcome Working code on a fixed slice Customer-ready system, production deploy
Best for "Prove this one piece can ship" "Take this from zero to production"
Founder access One Slack channel. Same person from kickoff to launch. Async-first, same-day reply. Included in both shapes.
Not for
✗ Marketing sites ✗ MVP prototypes ✗ Projects without real data ✗ Teams needing ten people

Response < 24h Async first Email or Slack
Good fit
✓ Real data and a clear technical wedge
✓ Shipped code, not a Figma handoff
✓ You know what you need built
✗ Marketing site or landing page
