Process

How an engagement runs.

  1. One-job scoping

    Week one. We pin down the single thing the product must do for the first customer and push everything else to a backlog. The output is an MVP small enough to ship and big enough to matter, with the SaaS roadmap sketched behind it.

  2. Design the core flow

    We design the path a user takes from signup to value, including tenancy and billing touchpoints, and skip the screens that can wait. You approve a clickable flow before we write feature code.

  3. Build sprints

    Two-week sprints with a deployed build at the end of each. Multi-tenancy, auth, billing, and onboarding come online in priority order. You and your early customers click the real thing every Friday.

  4. Launch

    We ship to production with subscription billing and analytics live, a landing page to collect signups, and the instrumentation to tell you whether accounts actually activate.

  5. Read and grow

    We look at real usage with you and pull the next most valuable item off the roadmap. You decide whether to keep building depth, expand tenancy, or refine pricing, with data instead of a hunch.

Stack

Tools we run with, by default.

  • Next.js
  • TypeScript
  • Postgres
  • Supabase
  • Clerk
  • Stripe
  • Resend
  • Tailwind CSS
  • Inngest
  • Vercel
  • Hetzner

We will work in your existing stack when it fits. We swap tools only when the cost of staying is higher than the cost of moving.

Pricing

Transparent, itemized, no day rates.

Custom quote

fixed price, scoped to you

Every engagement is scoped against your spec. Every proposal is itemized: design, build, content, and integrations — so you can sanity-check the math before signing.

Timeline

6 to 8 weeks to first MVP release, then ongoing sprints to grow the product

For mixed engagements (build + maintain), we bundle the proposal with a single price you can take to the board.

scoping to paying customers

B2B SaaS startup, Atlanta

Early-stage B2B SaaS team with a validated problem but no product. We ran a 6-week sprint from scoping through first release; 90 days later the team had 14 paying teams and had grown from $0 to $8K MRR.

Most clients run two or three of these together.

Stack thinking: paired engagements share one measurement layer, one accountability ledger, and one quarterly business review. That's where the compounding comes from.
