Startup and early-stage growth companies.
We support founders at startup and early-stage growth, pairing capital with advisory support as they build.
Stage
Sonnet Capital works with companies at startup and early-stage growth — early enough that founder-market fit and clear domain insight matter more than a finished playbook, and far enough along that there is a real product and real users to build from.
How we help
Capital is paired with advisory support: commercial thinking, positioning, go-to-market, and access to a board seat or advisory role where active guidance adds value. Where a company needs deeper, hands-on operational, strategic, or AI-implementation work, that sits with our sister company, Sonnet Advisors ↗.
What we look for
We don’t publish a fixed check size or a set list of must-hit metrics — every situation is different, and the right form of involvement depends on the company. What we do look for consistently: founders with clear thinking, real traction, and the discipline to sequence growth decisions well.

We don’t screen by a checklist before that conversation happens — bring the company as it is.
