Job Description

About the Company:

At Sybill.ai , we're building the next evolution in B2B sales – an AI-first platform that transforms how sellers work. Think of it as an intelligent sales IDE (Integrated Deal Environment), empowering sellers to focus on what truly matters: building relationships and closing deals.

Today, sellers spend 70% of their time on non-revenue activities. We're flipping this paradigm on its head. Sybill's AI lets sellers become super-performers who guide AI systems and focus on high-impact customer interactions.

Our proprietary AI technology, developed by a small but mighty team from Stanford, Harvard, and the IITs, and backed by leading investors in Silicon Valley, is not just another tool; it serves as the foundation of a groundbreaking sales workflow that delivers exceptional outcomes for our users. With 99%+ retention and 20x growth to $1.2M ARR last year, our customers' enthusiasm speaks for itself.

Our Engineering Culture

• Zero bureaucracy - direct access to customers and quick decision-making
• High ownership - you'll own features end-to-end from design to deployment
• Customer obsession - we build for real user needs and measure real impact
• Technical excellence - we tackle hard problems and build robust solutions
• Rapid shipping - we push code daily and see immediate customer impact
