The 90-day map

Every week accounted for
before we start.

The phase map you see at proposal. No moving goalposts, no scope creep dressed up as "discovery."

Discovery & specs

Whiteboarding, user stories, success criteria, technical scope.

wk 1-2

Prototype

High-fidelity, click-through, branded. Reviewed weekly with you.

wk 3-4

Sign-off & build kickoff

Locked scope, fixed price, two-week sprints from here.

wk 5

Build — core flows

Auth, data model, primary user journeys end-to-end.

wk 6-9

Build — depth & polish

Edge cases, integrations, observability, performance.

wk 10-11

QA, hardening & launch

Security review, accessibility audit, production deploy.

wk 12-13

Product launch

MVP economics

Ship months earlier. At half the burn.

Building 0→1 in-house takes 6-9 months and a year of salary before launch.

One in-house developer: $30k+ to recruit, 10+ hrs/week to manage, $500-2k/mo in tooling, severance risk if it stalls. Fixed price absorbs all four — ship before your next round.

how we build

Specs. Prototype.
Fixed-price build.

The same loop on every engagement. Predictable, observable, accountable.

Intake call

30 minutes. We hear the idea, the constraint, the user. We tell you whether MVP is the right shape.

Discovery

One-week paid discovery. Stakeholder interviews, user-story mapping, technical assessment. Walk away with a one-page brief and a fixed-price proposal.

Specs & Prototype

User flows locked, screens designed, edge cases mapped. You sign off on the design before the first line of code is written.

Build

Two-week sprints. Weekly demos. Code in your repo from sprint one. You see every PR, every deploy.

Hardening & launch

QA, security, accessibility audit. Production deploy with rollback plan.

Handover

Codebase walkthrough, ops runbook, post-launch on-call. Optional: extend via Dev On Demand for ongoing work.

What's included

Every role you'd hire — on day one.

The full team builds your product. The fixed price covers all six functions, end to end.

Product strategy

Outcome-led scoping, user-story mapping, success metrics defined before kickoff.

UX & visual design

Branded prototype, click-through, full mobile + desktop, signed-off before build.

Full-stack engineering

Modern stack — React/Next, Node/Python, Postgres. AI-augmented.

Infrastructure & DevOps

Cloud setup, CI/CD, observability, secrets management, rollback paths.

QA & security review

Manual + automated testing, dependency audit, security review before launch.

Production launch & handover

Live deploy with rollback plan, observability, on-call window.

In practice

MVPS we've shipped.

Two engagements, two industries. Both fixed-price, both shipped on schedule, both 100% founder-owned.

PineConnector · FinTech SaaS

The Challenge

Solo founder with a proven algorithm and a v1 that couldn't scale. Needed a production rebuild — live trades, paying customers — in under 90 days.

The Solution

Full MVP build: payments, account management, broker integrations, real-time signal routing. Figma sign-off in week 4, live in week 12.

The Transformation

Launched on schedule. Hundreds of paying customers at launch. Now a multi-thousand-customer FinTech SaaS, fully owned by the founder.

yourBI · B2B SaaS for hospitality data

The Challenge

POS providers rarely surface the data back to the owners running the restaurants, cafés and hotels. A B2B SaaS founder needed an MVP that could pull that data and turn it into insights for the end client.

The Solution

MVP shipped in 3 months: Figma prototype, three POS integrations on day one, branded BI dashboards. Second sprint: onboarding flow and admin panel.

The Transformation

Customer onboarding began at launch. Product commands premium per-seat pricing from day one. Founder retains 100% of the IP.

Vumacam · Security & Surveillance

The Challenge

A South African ISP subsidiary needed a license-plate recognition platform that could integrate with surveillance cameras, query the police database, and run at production scale from day one.

The Solution

MVP shipped in 10 weeks over the Christmas holidays: real-time camera ingest, plate recognition, police-database integration, search and storage.

The Transformation

Live in production since 2019. The 10-week Christmas build is now infrastructure for security investigations. Arrests and case closures route through it daily.

FAQ

Questions every founder asks.

Direct answers on scope, ownership and process. Anything else lands on the 15-min scoping call.

What does 'fixed price' actually cover?

The signed prototype is the contract. Everything in the design — every screen, flow, edge case — is in scope. Anything new is a change request, scoped and priced separately. You see the proposal before signing; nothing is hidden.

What if our requirements change mid-build?

Anything inside a sprint is locked; anything for the next sprint can be reshaped. Big changes go through a change-request process with a clear delta on price and schedule.

We don't have full specs yet.

Most clients don't. You leave discovery week with a one-page brief, a scoped prototype plan, and a fixed-price proposal — or you walk away with the brief and no further commitment.

Will we be locked into your team after launch?

No. Many extend via Dev On Demand or DTaaS for post-launch work. Your codebase, your call.

How do you handle confidential ideas?

Mutual NDA before discovery. We've shipped in fintech and regulated industries — confidentiality is a baseline, not a feature.

Who owns the code and IP?

You do. Always. IP-assignment is signed before any code is written. No licence-back, no carve-outs, no escrow drama.

What about post-launch support?

We include a one-month post-launch on-call window. For ongoing work, most clients extend via Dev On Demand.

Can we hire your team?

You don't. The team stays with us. Extend via Dev On Demand or DTaaS.

How we run engagements

Three principles, every engagement.

Excellence in execution

Production-grade work — reviewed, tested, deployed. Built to ship, not to demo. Modern engineering stack.

Evidence-driven solutions

Start small — audit, trial, or scoping. Scale based on findings, not pitches. Regular demos and written updates keep the work observable.

Relentless commitment to mission success

Outcome-tied delivery. We measure ourselves by your wins, not our invoices. Direct accountability to the people who hired us.
