Startup MVP — €500K Pre-Seed
A PropTech founder had 8 weeks before their first investor meeting and a working prototype in Figma. They needed a functional, demo-able product with real user accounts, real data persistence, and a credible technical architecture — not a click-through prototype. Traditional dev agencies quoted 3–4 months.

A PropTech founder had 8 weeks before their first investor meeting and a working prototype in Figma. They needed a functional, demo-able product with real user accounts, real data persistence, and a credible technical architecture — not a click-through prototype. Traditional dev agencies quoted 3–4 months.
Our Solution
We built a full-stack MVP in 3 weeks: WeWeb for the frontend (using Supabase Auth for login), Supabase for the database and Row Level Security, and Make.com for the onboarding automation (welcome email sequence, Slack notification for new sign-ups, CRM sync). The app had genuine functionality — property search, saved listings, landlord dashboards — not mocked data.
Scoping an MVP in 3 weeks
Three weeks is not enough time to build everything on a founder's wish list. We ran a 3-hour scoping session on day 1 using a MOSCOW framework: what is critical for the investor demo, what is important but deferrable, what is nice-to-have. We cut the landlord analytics dashboard, the automated contract generation, and the mobile app from scope. What remained was a clean, focused product that answered the single investor question: "Do landlords list properties and do tenants search for them?" We'd answer yes, and have 120 beta users to prove it.
Supabase as the full backend
For a 3-week MVP, Supabase's built-in auth, database, storage, and edge functions eliminate the need for a separate backend service. We used PostGIS (Supabase's geo extension) for the location search — a tenant can draw a circle on a map and get all listings within that radius. Row Level Security enforced that landlords only see their own listings in write mode, while search results are public. Supabase's instant API generation meant WeWeb could query complex joins via the auto-generated REST client without writing any backend code.
Investor-ready, not prototype
The key difference between a pitch deck prototype and an investor-ready MVP is what happens when an investor says "Can I log in?" We made sure they could. Before the first investor meeting, we onboarded 120 real beta users (recruited from the founder's network and a PropTech LinkedIn group). Investors could search real listings, see real enquiries, and ask "how many users do you have?" — the answer was 120, not zero. Three of the eight investors who saw the demo made term sheet offers.
Post-raise: scaling the no-code architecture
After the raise, the founder wanted to know if the no-code stack would hold at scale. We documented the architecture thoroughly: where WeWeb would need to be replaced by a custom React frontend (at ~50K concurrent users), where Supabase's managed Postgres would hit limits (at ~10M rows with complex joins), and what a migration path would look like. This transparency — acknowledging the trade-offs — is why we recommend no-code for MVPs: fast to build, fast to validate, and the migration path is well understood.
