You lived the problem, and built the solution. You have real revenue, rave customers, and have gotten this far with little or no outside capital. Your company is your life's work, and the way you've chosen to build it is rare.
Sonar is the first growth equity partner for rare founders like you.
So we start with what you want out of a partner: a minority stake, capital for growth or liquidity or both, an answer in weeks not months, and an aligned investor who can help you navigate the many firsts that lie ahead.
Richard and Darwish spent their careers in e-commerce. They built the first version as an internal tool inside their own d2c company, the one they scaled past $100M in revenue. Now they're on a mission to make selling internationally easy for everyone else.
Sudeep is an engineer by training. He built v1 on weekends after Covid, to monitor his parents' vitals from 8,000 miles away. That side project is now an AI operating system for virtual care, used by hundreds of specialty providers across the country.
Jean-Emmanuel and Simon are operators first. They built the tooling to survive running their own short-term rental management company in Philadelphia, then found every one of their peers had the exact same problem. Entirely bootstrapped by the time we met them.
Albert spent ten years on construction sites, losing hours a week to jobsite timekeeping nobody had solved. So he learned Python, ordered a Raspberry Pi, and built eighty-plus versions of a time clock himself. Now hardware and software used by some of the largest contractors in the country.
Yoni ran a growth marketing agency and kept noticing the same thing. His best customers were all ABA clinics, and they were all asking him for the same product. So he and Roy went all in on building the leading AI care enablement platform for ABA.
We want to be your first growth equity partner.
