Created a SaaS MVP for lead capture and follow-up in 4 days. The app helps founders capture lead and automate followup through a customized email sequence
LeadCapture - MVP
LeadCapture is a simple SaaS to capture leads and automatically follow up. Users create a project, drop one embed script on their site, and start collecting leads. Every lead can trigger a customizable email sequence (immediate, 1 day later, 3 days later, etc.).
Built as an MVP in 4 days.
The real problem
Most teams don’t lose leads because of traffic — they lose them because:
forms are hard to reuse across platforms
follow-ups are manual or forgotten
lead data is scattered
I wanted something that works everywhere and handles follow-up automatically.
What I built
Auth + multi-tenant setup (users, businesses, projects)
Project-based embed script users can drop on any website
Hosted form as a fallback for fast launch
Lead intake API that stores leads and triggers sequences
Email sequences with flexible delays (now, +1 day, +N days)
Clean dashboard to view leads and manage sequences
Subscription gating so automation only runs for active plans
Key decisions
Embed-first instead of platform-specific plugins
Database RPC for lead creation + follow-up scheduling to keep it consistent
Edge function + cron for delayed emails instead of a heavy job queue
Keep the UI minimal — focus on reliability, not features
Why this matters
This turns lead capture into a system, not just a form:
one snippet works on any site
follow-ups run without manual work
easy to extend (WhatsApp, custom domains, landing pages next)
Tech stack
React + Next.js (App Router)
Supabase (Postgres, Auth, RLS, Edge Functions)
Resend (email)
Stripe (subscriptions)
