Customer Engineer

Hi all! We're Seb (CTO), Finn (CEO), and Philipp (COO), building telli.com. What we do telli builds AI voice agents that automate phone calls for companies selling complex products like solar panels, mortgages, and insurance. Sales journeys with outbound calls convert far better than online-only funnels — but managing those calls has always been painful and expensive. Problem Companies rely on warm outbound calls to drive conversion, but scaling them is broken. They reach less than 50% of their warm leads on the phone. They pay ~$55 per connected call hour. And they have almost no quantitative insight into what's actually driving revenue from those calls. Solution telli is the AI call automation platform for B2C companies. With telli, businesses can reach leads with a smart calling strategy and multi-modal approach (SMS), make human-like calls in multiple languages, achieve clear outcomes like qualification, appointment booking, or direct transfers, and understand what's happening across thousands of calls at scale. For example, a leading home-buying platform uses telli to fully automate their lead pre-qualification. Team Finn and Philipp ran contact center operations for Enpal's heat pump unit — a $2.4bn European energy installer. They know this problem inside-out. Seb studied CS at Stanford and built software at Pitch before joining as CTO. We launched at Y Combinator and have grown to over $2M in annualized revenue with a team of just 12. Interested?
