Feature Sprint

One Feature, Shipped.

€6,000Fixed
2 Weeks

Single production feature on existing codebase, 2 weeks.

What you
actually get

Production is live. The roadmap has a feature your team can't quite get over the line — too complex for a junior, too small to hire for. Two weeks, one architect, one specific feature shipped end-to-end on your existing codebase: UI, server logic, persistence, tests, analytics, empty states, error states.

Scoping happens before the clock starts; the acceptance criteria are signed before week one. After handoff, you can scope another Feature Sprint or graduate to a Velocity Pod for ongoing capacity.

Scope cap

Hard limits

  • Features1 (with defined acceptance criteria)
  • User-facing screens≤ 5
  • New database entities≤ 3
  • New integrations≤ 2 third-party
What's included

In every Feature Sprint

  • Acceptance criteria document (signed before week 1)
  • All UI, server logic, persistence, tests
  • Empty states + error states + edge cases
  • Analytics events wired
  • 30-day post-ship bug fix window
Not included

Explicit exclusions

  • Feature spec / discovery (bring requirements)
  • Net-new architecture (use Blueprint first)
  • Cross-feature integration beyond the 1 feature
  • UX research / user interviews
The stack

Opinionated by default

One default stack for 80% of builds. Same stack shipped wintura.ai. Same stack the architect knows cold and has a runbook for at 3 a.m. When you swap pieces, the timeline goes up — the scoping call surfaces the swap before work starts.

Framework
Next.js 16 (App Router + RSC)
Marketing + product on one stack; Vercel deploys are boring in the good way
Language
TypeScript strict
Catches runtime errors at compile time so you don't ship them
UI
Tailwind v4 + shadcn/ui
Owned components, no library lock-in, evolves with you
Database
Postgres (Neon)
Boring tech, never the bottleneck, every team can hire for it
ORM
Drizzle
Type-safe SQL, transparent queries, zero runtime overhead
Auth
NextAuth v5 or Clerk
OAuth in 30 minutes, magic-link by lunch
Billing
Stripe
Nothing else is close at SaaS scale
Email
Resend
Best DX in the category, React Email templates included
Analytics
PostHog
Product analytics + feature flags + session replay in one tool
Errors
Sentry
Catch problems before users tweet about them
Hosting
Vercel
Edge runtime, preview environments, OG generation native
How we work

Operational rhythm

Not a process for show — the scaffolding that keeps a fixed-price engagement on track when life happens. Same rhythm across every Lift, Sprint, and Pod.

Daily commits

Every weekday, to a branch you can pull and run locally.

End-of-day async videos

3–5 min Loom summarizing decisions and blockers — review on your schedule.

Friday demo on Zoom

30 min walkthrough of what shipped that week — questions answered live.

Slack-first, decisions in 24h

Our workspace and yours linked. Questions get answered in a day, both directions.

What ships at the end

Concrete deliverables

No slide deck. No "phase 2 proposal." The list below is what hits your repo, your inbox, and your stack on the last day of the engagement.

01Signed acceptance criteria document (delivered pre-week 1)
02Feature UI + server logic + persistence + tests
03Empty states + error states + edge cases handled

What fixed-price actually means

Most agencies say "fixed price" and reserve the right to add a change order the moment the brief shifts. Soatech doesn't.

The way fixed price stays honest is by being unreasonable about scope. The scoping doc lists every flow, every screen, every integration. If something isn't on that list, it isn't in this engagement. If you discover during the build that you need it, the current scope ships as planned, and v1.1 begins after handoff — at the next tier's price, or as a follow-on Feature Sprint.

This sounds rigid. In practice founders consistently report it's the most valuable thing about the process — the discipline of saying "v1.1" thirty times across six weeks is what keeps the timeline honest.

Great fit

Teams with an existing production app needing one specific feature shipped fast. Post-MVP buyers who don't yet need an ongoing Pod.

Poor fit

Greenfield builds (use Blueprint + MVP Sprint). Ongoing feature pipelines (use Velocity Pod). Feature discovery / spec work.

Book · Direct, no SDR

Skip the sales reps. Book the Architect directly.

30 minutes. Scope your project with a senior architect — the same studio that shipped wintura.ai. Your assigned architect is confirmed after scope sign-off.
