PandaMatch
Finding companies like a seed set, cheaply, down to small sites not on LinkedIn. A fit for agencies and local-market teams.
PandaMatch is a company-discovery tool. You give it up to 10 domains, keywords, an exact text fragment or a written description, and it returns company domains with a similarity score, public emails and phones from the sites, social links and an address.
