Mattermark is a B2B company-intelligence and data platform focused on discovering, researching, and tracking primarily private companies and investors. It combines firmographic data (e.g., state, industry, generalized employee-band), people/contact data, and derived "growth signals" (e.g., employee growth trends, web traffic indicators, media mentions) to support:
- Deal sourcing for investors
- Prospecting and account research for sales/BD teams
- Market/competitive research for professional services
Mattermark is positioned as a tool for deal sourcing that uses structured and derived data. It is available via a web app, spreadsheet integrations, CRM integrations (notably Salesforce), and APIs (REST + GraphQL). The vendor publishes claims of broad company and contact coverage and many fields per company.
