Vector Labs
AI tooling · Pre-seed (3) · Berlin, DE
Vector Labs ships an open-source vector database for embedded ML teams. The three founders write code most of the day — they don't have a salesperson. The Dataroom proposal does the work: pricing, video intro, signature, payment. They wake up to closed deals.
Built one async proposal
Pricing table, embedded 90-second product walkthrough, ROI calc for embedded ML teams, accept-and-sign block at the bottom.
Killed the demo call
Replaced “book a demo” on the website with “see a sample proposal.” Inbound jumped 3.5x in two weeks.
Wired Stripe + Slack
Accept block triggers Stripe checkout, which fires a Slack ping. Done deal: no human required.
Hit $2.4M ARR
12 months later, three founders, no salesperson, $2.4M ARR. Average sales cycle: 12 minutes.
“We don't have a salesperson. The proposal does the work — pricing, video, sign, paid — and we wake up to closed deals.”
