The story
Founded in 2018 as a KYB (Know Your Business) verification platform, Middesk built direct integrations with the IRS and Secretary of State databases across all 50 US states. Following its 2022 Series B, the company expanded beyond identity verification into adjacent workflows — payroll tax registration and continuous business monitoring — positioning itself as the business-identity infrastructure layer for banks, lenders, and payroll platforms.
