How this list is built: where we have researched a company’s total funding, that figure decides (under $10M is listed). Otherwise a company is listed when it was founded within the last three years, its funding stage is Pre-Seed, Seed, bootstrapped or early-stage (or Series A with tracked rounds under $10M), and the Deal Tracker shows no financing of $10M or more. Companies with an undisclosed or unspecified funding stage are not listed.
