Kurt Ruppel is the Co-Founder and CTO of Middesk, the business identity platform that helps financial institutions, fintechs, and marketplaces verify and onboard businesses in seconds rather than weeks. A UC Berkeley cognitive science alumnus turned engineer, he built his technical chops at Zendesk and Checkr before co-founding Middesk with Kyle Mack in 2018. The company went through Y Combinator's Winter 2019 batch, secured a $4M seed led by Accel and Sequoia before Demo Day ended, and raised a $57M Series B in 2022—bringing total funding to over $77M. Ruppel leads Middesk's technical vision, focusing on primitives and forward concepts that transform raw business data into actionable intelligence for the financial ecosystem.
Kyle Mack is the CEO and Co-founder of Middesk, the business identity platform that's modernizing how financial institutions and fintechs verify and trust the companies they work with. Founded in 2018 after Mack witnessed firsthand the painful manual process of customer credentialing at Checkr, Middesk has grown into a category-defining KYB infrastructure company backed by Sequoia Capital, Accel, Insight Partners, and Canapi Ventures with $77M+ in total funding. The company serves hundreds of enterprise clients - including two of the top three U.S. banks and fintechs like Plaid, Affirm, Brex, and Shopify - by connecting to roughly 400 U.S. government agencies to surface real-time business identity intelligence. Mack is also a Sequoia Scout, investing in early-stage founders.
