Why $300B of SaaS Revenue Is Trapped & How the $19.9T AI Agent Economy Unlocks It

Manny Medina, Co-Founder & CEO of Paid and former CEO of $4.4B Sales Tech company, Outreach, hosts Sourcery at their HQ in London to discuss the early development of AI agents & what this shift means for software businesses.

Roughly $300 billion in SaaS revenue remains “trapped” in legacy pricing and delivery models. After scaling Outreach to 6,000 customers, 220,000 active users, and $250M in ARR, Manny saw firsthand that many SaaS monetization frameworks don’t fit agentic systems, which perform full end-to-end workflows rather than individual user-driven tasks. This gap led him to build Paid, the platform designed to help companies measure, price, & manage the economics of agents.

And it's working.. early customers have reported 20–40% revenue growth within six months of adopting the platform.

With $33.3M in total funding, Paid is backed by Sequoia Capital, Lightspeed Venture Partners, EQT Ventures, GTM Fund, & FUSE.
