AI outbound that books meetings. Building fifteenA with my cofounder Mustafa. An AI engine that watches the internet 24/7 for real buying signals and books 5–7 qualified meetings a week straight into our customers' calendars.

I'm building fifteenA with my cofounder Mustafa. Outbound is broken : SDR teams burn out, generic spam doesn't land, and real buying signals slip by unnoticed. We replaced the BDR team with an AI engine that watches the internet 24/7, spots companies with real buying signals, writes outreach tuned to each lead's pain points, and books qualified meetings straight into our customers' calendars.

Already live with paying pilots and outcome-based pricing — customers only pay for meetings we book, with a 1-week setup. I dropped out of my M.Sc. at TUM and UC Berkeley (3/4 done, top 2%) to build fifteenA full-time. I've been deep in AI agents since 2023 and trying new models and frameworks as soon as I can get my hands on them.

fifteenA

Cofounder

An AI outbound engine — a dedicated BDR team, working 24/7. Watches the internet for real buying signals, writes outreach tuned to each lead's pain points, and books 5–7 qualified meetings a week straight into customers' calendars. Live in production with paying pilots and outcome-based pricing — customers only pay for meetings booked.
