Staff Software Engineer FullStack

About Sybill :

At Sybill.ai , we are building a 10x better way to do B2B sales via an end-to-end, AI-first GTM stack that unlocks unprecedented levels of automation for the sales reps.

The existing GTM stack only gives reps a better UX to do their admin tasks. With Sybill, reps will not need to do them at all.

All they will need to do is take customer calls and supervise the AI, enabling them to be super-sellers.

Our founding team from Stanford, Harvard and IITs has built a sales-specific, proprietary AI to extract highly accurate deal attributes, which unlocks these workflows.

This AI-first GTM stack will disrupt both today's pigeonholed tools (Gong, Highspot, Scratchpad, Clari, Outreach) and remove the need for extensive middle management in GTM orgs.

With Sybill's conversational AI workflows, reps are seeing a remarkable behavior switch in their day-to-day and they just can't stop using the product (gross retention - 99%+).

They are vocal about their love for Sybill on LinkedIn, enabling us to grow 20x to $1.2M in ARR last year.
