Prospetto.ai
A B2B sales-intelligence platform serving 200M+ verified contacts.
What we set out to solve
Sales teams waste hours stitching together company and contact data from a dozen tools, and most of it is stale. The platform had to unify 200M+ contacts across 600+ data sources, keep them fresh, and make enrichment and outreach fast enough to actually use in a workflow.
What I built
- 01
Enrichment at scale
I built enrichment modules on a Redis + BullMQ job pipeline that resolve a company from sparse input and hydrate it with firmographic data normalised across hundreds of sources, persisted across a hybrid Postgres + MongoDB store.
- 02
Email finder
Built the email-finder path that derives and verifies contact addresses, so reps get a usable address rather than a guess — reusing the same verification discipline as Verifox.
- 03
Personalised outreach
Added OpenAI-backed outreach modules that turn the enriched data into tailored, per-prospect messaging instead of generic blasts, with Stripe-metered usage.
