Meridian, the AI-powered deal management platform for the private markets, today announced its $7 million Series Seed fundraise. The round was led by 645 Ventures with participation from existing investor Chaac Ventures. Meridian also welcomed a group of high-impact angel investors, industry leaders from private equity, credit, and M&A law, many of whom have actively shaped Meridian as early users.

Founded by Alexander Sen, a former investor at Blackstone, Thoma Bravo, and CVC, Meridian is building the AI operating system for private market investors. The company combines modern CRM with deep workflow automation and proprietary AI agents to solve the core operational pain points of the world’s leading investors – from deal origination to exit.

“Private equity still runs on fragmented, manual systems: clunky software, Excel trackers, and scattered third-party data subscriptions,” said Alexander Sen, founder and CEO of Meridian. “We’re building software that finally reflects how top investment teams source and diligence deals – and we’ve vertically integrated AI to enable workflows that were never possible before.”

“There’s a generational shift happening in private markets – more complexity, more competition, and more data,” said Nnamdi Okike, Managing Partner at 645 Ventures. “AI is a game changer for private market deal sourcing, due diligence and deal management. Firms that do not leverage AI in this new market will be left behind. We were particularly drawn to Alex’s insights into how AI will transform private markets, which were developed through his experience in private equity. Meridian is arming investors with the system they’ll need to win.”

The funding will be used to expand Meridian’s AI capabilities, accelerate product development, and scale go-to-market efforts globally.

“Private market firms are under pressure to move faster, operate leaner, and make sharper decisions,” said Sen. “Software is no longer just overhead at private equity firms – it’s become a source of edge. The best investors are treating technology and data as central to how they generate outsized returns.”
