Sales is the economic engine of every company and presents an addressable market of $28B. We're solving one of the most complex and high revenue-generating problems with a multi-modal approach including chat, email, voice, and beyond. This gives us a significant advantage in the market, and presents exciting engineering opportunities.
We are a small, experienced team building a multi-billion dollar AI-first company in the heart of NYC. We value depth of experience, thoughtful technical decisions, and sustainable development practices to build consistent momentum over the long-term.
Spara has raised $15M from top-tier venture capital firms , led by Radical Ventures & Inspired Capital; AI luminaries including the founders of PyTorch and Google Cloud TPU, as well as the Head of Sales at Anthropic and Head of Platform Sales at OpenAI.
We are led by multi-time founders with deep go-to-market and AI expertise.
David was co-founder/CEO of Triplemint, where he ran training, coaching, and operations for a 250 person sales team. He grew the company to successful acquisition and now sits on the board of The Agency RE, a $250M revenue business.
Zander was the technical co-founder of Nomad Health, now a post-Series D company. He most recently ran Platform at Hyperscience AI, building a workflow orchestration layer for computer vision models.
We are growing our team of experienced operators at the forefront of applied AI.
