Three founder situations

Where you are today decides the first move.

Most founders we hear from arrive in one of three shapes. None is harder than the others, and the right next step looks different for each. Tell us where you’re sitting in the first email and we’ll match the response.

A Pre-seed

You have a sketch, a grant or an angel cheque, and no team yet.

The right next move isn’t a full MVP. It’s the smallest possible product that lets a stranger pay you. We pick that thing with you in week one, ship it on a fixed scope, and protect your runway for the round that funds the real product.

  • 4 to 6-week concierge MVP
  • Investor-ready technical narrative included
  • Walk-away clause from day 1
  • Fixed-scope concierge MVP · from £25K
B Post-seed

You have customers using a fragile MVP and a Series A on the horizon.

The MVP held together for the seed round, but it won’t hold for the next 50 enterprise customers or the technical due-diligence call. We audit in week one, rebuild the spine over 8 to 16 weeks, and stand up architecture that survives the Series A partner’s questions.

  • Architecture audit + senior pod rebuild
  • Documentation that survives a CTO hire mid-build
  • Clean handover when your in-house team is ready
  • Architecture audit + rebuild · from £55K
C Post-PMF

You have growth, an in-house team, and one expensive decision coming.

Multi-region, multi-tenant, AI features, cost engineering on cloud and inference. The next architectural call sets the next 18 months of your roadmap. We sit alongside your in-house engineering team as a second senior voice on the decisions that matter most.

  • Architecture-only advisory or embedded senior
  • Quarterly architecture review with your CTO
  • Cost engineering for cloud, AI, and data
  • Advisory or embedded senior · from £5K/mo
What you walk out with on day 42

Four artefacts. Investor-ready.

01

Architecture diagram

One page. Every spine decision, named. The version your Series A partner reads first.

02

Six-page scope

Signed in week 0. The “not in this build” list locked. The trade-off log open for revision.

03

Measurement dashboard

Activation, retention, conversion, cost-to-serve. One screen. Your investor reads it in 60 seconds.

04

Clean handover

Documented codebase. Decision log. A new engineer is productive in their first fortnight, not their third month.

What we build for founders

The stack we ship MVPs on. Battle-tested. Boring. Fundable.

We pick tools that survive the Series A due-diligence call. Boring choices that scale. Nothing experimental on the spine. Founders get the architecture investors expect, with the option to layer fashionable tech on top once the boring core is paying for itself.

01

Web product

Next.js + TypeScript. The default for B2B SaaS, dashboards, and consumer web MVPs.
Next.js 14+TypeScriptTailwind + shadcn/uitRPC or RESTVercel + Cloudflare
02

Mobile MVP

React Native or Flutter. Cross-platform shipping to App Store and Play Store from week three.

The 42-day founder sprint

6 weeks. Seven milestones. One real customer.

Week 0

Audit + architecture

One week reading what you have. Mohit drafts the diagram. You sign the scope.

Week 1

Foundations

Database, auth, payments, deploy. The four calls your investor will check.

Week 2

Core path

The one job your first customer pays for, end-to-end, on staging by Friday.

Week 3

Friction pass

Three real users. Every pause logged. Onboarding, errors, empty states fixed.

Week 4

Measurement live

One dashboard, four numbers. Activation, retention, conversion, cost-to-serve.

Week 5

First customer, live

Real account. Real card. Real invoice paid. Not a beta. Not a friends-and-family launch.

Week 6

Handover + narrative

Documented codebase. Architecture diagram. A 1-page investor narrative.

Founder pricing in GBP

Three prices. On the page.

GBP throughout. UK VAT applies. Reverse-charge for EU. No VAT for non-EU. Milestone payments structured around your runway, not ours. Equity-in-lieu only on a small fixed share, only after the sprint has shipped.

Audit

Mohit + one principal engineer read what you have, draw what you need, and hand back a one-page diagram, written trade-off log, and a costed rebuild plan. Often signed standalone before the bigger build. Right when there’s a codebase and you can’t name what’s wrong with it.

MVP sprint

The full sprint, fixed scope and fixed price. B2B SaaS web: £35-55K. Consumer mobile: £45-70K. Fintech / compliance: £55-80K. Three milestone payments around your runway. Right when the idea is real and the next 6 weeks decide the round.

Advisory

Weekly standup with you or your CTO. Architecture review every fortnight. The call before the next round of feature creep. Available after the sprint, or standalone for founders with an in-house team. Right when you don’t want the next architecture call made alone.

Architecture investors check

Six decisions. Made in week one. Defended at the next round.

Every Series A technical due-diligence call we’ve sat in on starts with the same six questions. We make the answers in week one of the sprint, write them down, and hand them to you in a one-page architecture brief. By the time your investor asks, the answer already exists.

01

Database choice and schema model.

Why Postgres and not the alternative. Why this schema and not the obvious one. How multi-tenancy works at the data layer. What the migration path looks like at 100x current load.

Proof: schema diagram · decision log · load-test script
02

Auth and identity boundary.

Where the auth service ends. How session, role, and tenant interact. What happens when you add SSO. Why the boundary lives where it does.

Proof: auth flow diagram · threat-model summary · audit log
03

Payments and audit trail.

Why this PSP. How idempotency works on every charge. Where the audit log lives. How reconciliation handles a dispute. Why the schema survives FCA, PCI, or PSD3 questions without a rewrite.

Proof: payment flow diagram · reconciliation playbook · PCI boundary
04

Deployment and observability.

How a feature goes from PR to your customer. What you do when it goes wrong at 3am. Why CI passes don’t mean production passes. How on-call reads health.

Proof: CI/CD pipeline doc · on-call runbook · dashboards
05

Unit economics and cost-to-serve.

What it costs to serve one customer today. What it will cost at 100x. Where AI inference, data pipelines, bandwidth, and third-party tools sit on the bill. Which cheaper alternatives have already been chosen.

Proof: unit-economics sheet · cost-to-serve breakdown
06

Security and data protection.

UK and EU GDPR posture. DPA on file. SOC 2 path costed with milestones. How a Data Subject Access Request is served. How a leaked credential gets shut down before lunch.

Proof: DPA · security policy · incident runbook · SOC 2 roadmap
Industries we’ve shipped MVPs in

Founders we’ve shipped for. Sectors we know the calls in.

We’ve shipped 27 founder MVPs since 2019 across these seven sectors. Each has its own architecture calls, regulatory weight, and investor-due-diligence flavour. We’ve made them already, so your sprint doesn’t pay for the learning.

Fintech · 9 MVPs

Payments, wallets, lending, settlement.

FCA-aware, PCI-aware, PSD3-aware schemas.

B2B SaaS · 7 MVPs

Multi-tenant platforms, SSO from week one.

Enterprise audit logs, SOC 2 paths.

Health + clinical · 4 MVPs

UK GDPR + NHS DSPT alignment.

IG-toolkit-aware data flows. Clinical safety baseline.

Marketplaces · 3 MVPs

Two-sided onboarding, split payouts.

Trust + safety review queues, dispute handling.

Consumer mobile · 2 MVPs

App Store review handling.

RevenueCat subscriptions. Push and lifecycle systems.

AI-first products · 5 MVPs

Production RAG, structured agents.

Eval harnesses, cost engineering on inference.

Climate + impact · 2 MVPs

Grant-funded builds.

Outcome reporting baked into the product. Innovate UK milestones.

We say no a lot

We turn down 1 in 3 projects we hear from.

The right partner is the one who knows when they’re wrong for the work. Three reasons we’ll say no kindly — sometimes inside the first reply.

01 No, for now

Pre-seed, no paying customer, plenty of design.

Ship the cheapest version yourself first. Find real signal. Then talk to us.

02 Not our category

The category isn’t ours.

Hardware-first robotics, AAA game engines, regulated medical devices. We’ll name a builder who does it better.

03 Wrong brief

The brief skips the architecture call.

“Just start shipping, we’ll figure it out.” If that’s the brief, we’re the wrong studio.

Three founders, three outcomes

Anonymised by contract. Verifiable on a call.

Compliance doc-extraction tool
B2B SaaS · 2023

Compliance doc-extraction tool

Notion doc + £180K pre-seed. We shipped in 6 weeks. Three paying customers in month two.

Two-sided creator platform
Marketplace · 2024

Two-sided creator platform, rebuild

Seed-round MVP breaking at 200 creators. We rebuilt the spine in 14 weeks. CTO hired against our codebase.

Clinical triage MVP
Health AI · 2025

Clinical triage MVP, NHS pilot

Non-technical founder. £120K Innovate UK grant. IG team approved the architecture on first review.

Common questions from founders

The five we get every week.

I’m not technical. Can you still work with me?

Yes. Half of the founders we ship for are non-technical. Every architectural call is explained in plain English, translated into the business decision behind it, and re-readable in writing.

What if my idea changes mid-build?

Scope is locked in writing in week 0, with a “not in this build” list. Changes get costed in writing and brought to a Friday call. Three options: drop, slip, or roll to a follow-on. Your call.

Will you take equity instead of cash?

Only in part, only after the sprint has shipped, only on a small fixed share. Equity-in-lieu is a tax problem and a relationship problem if used to fund a whole sprint.

What if my round doesn’t close in time?

Tell us early. Milestone payments are structured around your runway and round timeline, not ours. Three founders raised three weeks late in the last 18 months. All three sprints finished.

I already have a dev team. Can you sit alongside?

Yes. The post-PMF model is built for that. We become the second senior voice on the calls that matter. We’d rather make your team better than replace them.

If you’ve read this far

Send the founder note. We’ll read it carefully.

Five lines is enough. Tell us where you’re sitting, what you’re trying to ship, what your runway looks like. A real reply inside 24 hours. A kind yes, a kind no, or the one question that decides it.
