Rapid MVP sprint

Four weeks. Fixed price. Live or your deposit back.

The Rapid MVP Sprint is our signature engagement for founders and product teams with a concrete idea and a deadline that can’t move. You get a working, production-deployed MVP in your customers’ hands 28 days after kickoff — or we refund your deposit, no arguments.

How it’s possible (because “MVP in 4 weeks” is usually a lie)

Most “4-week MVP” offers end in month three with a half-built prototype and an apology. Ours works because we’re structurally different:

• Tight scope on purpose. We only commit to what fits in 28 days. Scope creep kills MVPs. If you want more, we plan a phase two.
• Senior operator end-to-end. The person you brief is the person coding. No junior handoffs, no account-manager telephone.
• Boring tools where it matters. We use tools we’ve shipped with a hundred times. Reliability comes from familiarity.
• AI automation where safe. Code generation, test writing, copy drafting — aggressively AI-assisted internally, with senior review at every seam.
• Fixed scope, fixed price. We eat our own estimation errors. You never get a surprise invoice.

The 28-day timeline, day-by-day

Week 1 — Validate (days 1–5)

• Day 1: Kickoff workshop (half day, video or in person). We pull the idea apart — target user, core value, first five features.
• Days 2–3: Problem interviews with 3–5 of your target users or internal stakeholders. Recorded, transcribed, summarised.
• Day 4: Tech feasibility spike — we try the riskiest technical assumption for real. If the approach doesn’t work, we find out now, not in week 3.
• Day 5: Go / no-go review. If the idea won’t work as scoped, we tell you, hand back the deposit, and help you plan what to do next.

Week 2 — Architect (days 6–14)

• Days 6–7: UX prototype in Figma — clickable, not just static frames. Two rounds of revisions.
• Days 8–10: Data model, API contracts, infrastructure plan locked. You get the architecture diagram; we don’t start building on sand.
• Days 11–14: Design-review checkpoint (end of week 2). Sign-off on UX, architecture and stack before we write production code.

Week 3 — Build (days 15–25)

• Day 15: Repositories, CI/CD, staging environment, monitoring all stood up.
• Day 17: First working feature on staging — you can log in and click things that do real work.
• Daily: New increments shipped to staging. Async Loom walkthroughs at the end of each day. A 30-minute sync whenever you want one.
• Day 25: Feature-complete on staging. Bug list started.

Week 4 — Ship (days 26–28)

• Day 26: Production deploy, smoke tests, security headers, analytics wired.
• Day 27: Onboarding docs, admin training, handover video. First real users given access.
• Day 28: You’re live. Champagne moment. Your MVP is in the hands of real customers.

Example scopes that fit a 4-week sprint

These are representative projects — yours will be scoped to fit the 28-day window:

• Crypto / DeFi: DEX frontend with CEX liquidity routing, wallet connect, on-chain settlement for a single chain.
• Trading systems: Multi-exchange arbitrage bot with per-market risk controls, position sizing and a dashboard.
• IoT & home automation: Home-automation hub with Matter support and HomeKit / Google Home bridging for a starter device set.
• LegalTech / HealthTech: AI classifier with human-in-the-loop review, audit trail, export to PDF.
• FinTech: KYC onboarding flow with live identity verification, AML screening and case-management console.
• AI sales: Outbound SDR agent with CRM sync, email + SMS cadences, booking flow, one voice integration.

Not on the list? Pitch it to us. A 30-minute call is enough to know if it fits a sprint, or whether it needs a longer engagement.

Pricing

• Focused sprint — single-track idea, one persona, one integration. From $24,000 fixed.
• Standard sprint — most engagements land here. Multi-screen product, two or three integrations, basic admin. $32,000–$42,000 fixed.
• Deep sprint — heavier technical spike (crypto, trading, IoT firmware), complex state, multiple user types. $42,000–$48,000 fixed.

All prices include the validation, architecture, build, and launch phases. Third-party costs (domains, hosting, API credits) are yours to pay directly — we help you set the accounts up in your name.

Finance options

For qualified clients we offer milestone payment plans (40% deposit, 30% at architecture sign-off, 30% on launch) at no extra cost. For strong teams with product-market fit, we’ll consider hybrid equity engagements case-by-case. Ask us — we come back with options in writing inside 48 hours.

The deposit-back guarantee, precisely

Here’s what “or your deposit back” actually means, so there’s no ambiguity later:

• If we don’t ship to production by day 28 and the reason is us, your deposit is refunded in full within 7 days.
• If we find on day 5 that the idea won’t work as scoped, your deposit is refunded in full and you walk with the validation artefacts.
• If the reason we miss is you (late feedback, scope changes, access not granted), we’ll extend the timeline free but the deposit isn’t refunded. We’ll tell you in writing the moment a delay becomes yours, not ours.

What we won’t do in a 4-week sprint

• We won’t build regulated products (banking, healthcare decisioning, investment products) where compliance review takes longer than 28 days. For those, the sprint becomes the first phase of a longer engagement.
• We won’t commit to ship features nobody has validated. If we can’t get five user conversations in week one, we slow down.
• We won’t skip the staging environment, the backups, or the security headers. Rapid isn’t an excuse for sloppy.
• We won’t train on your customers’ data without their explicit, specific consent. Ever.
