The SaaS MVP that validates the right things gets to Series A. The one that validates the wrong things gets rebuilt.
We build SaaS MVPs that validate your core product thesis — not feature-complete products that take 12 months to learn anything from. Fixed scope, fixed price.
Your MVP needs to be wrong about the features and right about the infrastructure. Getting the multi-tenancy, billing, and auth wrong in v1 means you're rebuilding foundations at the worst possible time — when you have paying customers and a Series A data room open.
SaaS MVPs fail for two distinct reasons. The first is building too much: spending six months building every planned feature before anyone has validated whether the core insight is correct. The second is building on the wrong foundations: shipping fast with a single-tenant database, no billing infrastructure, and an authentication model that was bolted on after the fact — then discovering that the first enterprise prospect requires multi-tenant data isolation, SSO, and role-based access control that would require rebuilding the data layer to support.
The correct SaaS MVP is a deliberate trade-off: narrow on features (the smallest set that validates the core thesis with the target customer), correct on infrastructure (the data model, auth, and billing that won't block your first real customer). Getting that trade-off right requires having built SaaS products before and knowing which shortcuts are recoverable and which ones aren't.
Multi-tenancy is non-recoverable. Billing model is non-recoverable. Auth infrastructure is expensive to replace. Feature scope is recoverable — you can add features. Fixing a single-tenant database with live customer data is a multi-week migration with real downtime risk.

Core product features scoped to the thesis
One to three primary features that validate the core user value proposition. No secondary features, admin panels, or configuration interfaces that don't contribute to the validation experiment. Scope discipline is a deliberate choice.
Multi-tenant data model
Postgres with Row Level Security scoped to an organisation ID. Every data table is tenant-scoped from the first schema migration. Adding tenants is a row insert; no schema changes, no data migration risks.
Stripe billing with plan management
Subscription creation, plan selection, and billing email — even if you're charging $0 for the beta. Having billing infrastructure from the start means you don't have to rebuild checkout when you start charging.
Authentication and team invite
Clerk-powered email/password, Google SSO, and magic link. Organisation creation and invite-based team member onboarding. Role assignment (admin vs. member). Session management.
Deployment and monitoring
Vercel deployment with preview environments. Sentry error tracking. Basic uptime monitoring. A system that you can confidently give to beta customers without babysitting. Built on Next.js, TypeScript, Postgres, Clerk, Stripe, and Vercel.
One honest number to start.
Fixed-scope, fixed-price. The number below is the starting point — final scope is built from your brief.

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
SaaS founders building an MVP are managing burn rate against the moment they can validate enough to raise or charge. Fixed scope and fixed price is how you hold the line on that burn — not an open-ended hourly engagement that expands as you discover new requirements.

Questions, answered.
We start discovery with a product brief review and a prioritisation framework: what's the single user action that creates the "aha moment" for your target customer? Every feature in scope must be on the path to that moment. Features that aren't get deferred to v2.
Invite-only betas have the advantage of controlled feedback loops and lower infrastructure costs. Public betas have the advantage of faster validation velocity. For most SaaS MVPs, we recommend invite-only with a public waitlist — you get signal from interested buyers while controlling the user set you're learning from.
Typically 4–8 weeks from MVP launch to first v2 feature release, assuming you're collecting feedback from beta users from day one. The MVP build includes a contribution-ready codebase structure — new engineers or the same team can add features cleanly.
Core features, multi-tenant infrastructure, Stripe billing, and auth typically runs $25k–$50k. The feature scope is the primary cost variable. Fixed-price.
8 to 12 weeks from discovery to MVP live in production.
