Paid, ‘Results-Based Billing’ Startup From Manny Medina’s AI Agent, Raises $21M Seed

London, 30th of September 2025 — Paid, a startup by London-based serial tech entrepreneur Manny Medina, has secured $21 million in new funding, led by Lightspeed and supported by EQT Ventures and FUSE. The latest round brings the company’s total funding to $33.3 million, which also includes a €10 million pre-seed round earlier this year. It’s worth noting that Paid is still in its infancy, with a valuation already north of $100 million.
Manny Medina, the founder and former chief executive of sales software developer Outreach, believes he may have his next success by solving one of the hardest problems facing commercial artificial intelligence — how to use software to speed up and improve the performance of human sales agents. Conventional billing models, such as flat subscription fees or unlimited usage fees, do not always represent the value that the AI product actually brings. Paid developed a “results-based billing” model to enable AI developers to bill clients for measurable results delivered by their agents.
Innovative Billing Model
The core of Paid’s platform enables AI developers to implement outcome-based pricing. Key features include:
- Performance-based fees: Developers can charge clients based on the actual business value delivered by AI agents, including operational savings, efficiency gains, or increased revenue.
- Alignment with real impact: This model ensures payment is tied to performance, addressing a key limitation of traditional pricing models that often underestimate the impact of AI agents.
- Suitability for AI operations: Many AI agents are associated with single interactions where their contributions are not immediately visible. Results-based billing aligns the interests of developers and clients, ensuring that success can be measured in tangible results.
Strategic Vision and Market Potential
Paid’s platform emerges at a critical moment in the AI evolution, as autonomous agents are increasingly used across industries such as:
- Customer service
- Sales and marketing
- Human resources
- Finance
Despite widespread adoption, robust monetization strategies remain scarce. Paid addresses this gap by offering a scalable and fair billing system, capable of accurately reflecting the value created by AI agents.
The oversubscribed seed round demonstrates investor confidence in Paid’s model. The new funds will be used for:
- Enhancing platform capabilities
- Improving user experience
- Expanding the network of AI developers
Through these steps, Paid is positioning itself as a pioneer in the emerging field of results-based billing for AI agents.
Implications for the AI Economy
Paid’s approach carries broader implications for the AI economy:
- Developer incentives: Linking revenue to results encourages developers to optimize AI agents for real-world impact rather than mere activity.
- Client transparency: Clients benefit from clarity and assurance, paying only for measurable outcomes instead of potential results.
- Market transformation: This model could reshape how AI products are purchased and deployed, fostering better solutions through stronger collaboration between developers and users.
Conclusion
Paid addresses a significant problem in AI monetization with its innovative billing system. By tying compensation to the actual results delivered by AI agents, the platform provides a fairer, performance-driven pricing model. As AI continues to expand across various industries, Paid’s results-based approach has the potential to set a new standard for measuring and leveraging AI assets.
