The challenge
Outbound teams stitch together a prospecting tool, an email sender, a design tool, a scheduler, and a spreadsheet — then lose the thread between them. The goal was one platform that sources leads, generates the creative, runs the campaign, receives the replies, and reports on all of it without leaving the app.
Our solution
We built a React + Vite front end over a Python/Django backend with Neon Postgres behind an ORM and Vercel Blob for storage. Apollo feeds prospecting, Unlayer powers the in-app email builder, Buffer and direct Facebook, Instagram, TikTok, and LinkedIn integrations handle publishing, and Gemini with Google Cloud drives in-app image and video generation. Campaign automation, lead automation, and a built-in inbox close the loop, with Stripe for billing and Sentry for error visibility.
The results
Prospecting, creative generation, campaign automation, replies, and social publishing run inside one product rather than five subscriptions. Because generation and sending are in-app, a campaign can go from lead list to published creative without an export step.
