Ampersand closes generation gap between agents and the enterprise software stack, backed by $15 million from Bessemer Venture Partners

Ampersand lets agentic applications read and write inside legacy systems of record, removing the integration work that has stalled AI projects industry-wide.

SAN FRANCISCO, Oct. 6, 2026 /PRNewswire/ -- Ampersand today announced a $15 million Series A led by Bessemer Venture Partners, with participation from existing investors Matrix and Flex Capital. New investors participating in this round also include Yelp, Tenacity Capital, CTO Fund, Mana Ventures, and prominent angel investors. Lauri Moore, Bessemer Partner, will be joining Ampersand's board. Ampersand is building integration infrastructure for enterprise agents, so agentic applications can read and write inside the CRM, ERP, and other systems of record that power the enterprise.

While enterprises are ready to adopt agentic software, they are running into a practical issue: legacy systems of record. CRMs and ERPs in different verticals have been around for decades, and every implementation is highly customized. AI-native software vendors looking to sell to the enterprise are faced with needing deep domain expertise on how these systems function before they can deliver value to enterprise customers. This practical reality slows AI adoption for the enterprise and limits the market size for AI vendors.

"With Ampersand, we're able to serve new customers that were previously unavailable to us because of their complex integration requirements," said John Pena, CTO at Hatch, an AI communications platform for service businesses, acquired by Yelp in 2026. "Now we've expanded our total addressable market without taking on months of maintenance headaches."

Ampersand is closing the gap between legacy systems and agentic products by making every customers' system legible to agents. Ampersand's approach to legacy systems allows every end customer to adopt a custom data model that can handle custom fields, objects, permissions, and workflows so agents have the right context. Then enabling agents to take deep, bi-directional actions in these systems of record.

"We're in this fascinating moment where AI has the potential to transform the enterprise, but CTOs are still faced with the old problem of systems of record," said Ayan Barua, co-founder and CEO of Ampersand. "Our bet is that the saasapocalypse is overstated and systems of record like Salesforce and NetSuite aren't going anywhere. Ampersand is designed to sit between these two generations of software and make them legible to each other."

Ampersand's mission is to provide a complete integration solution for AI-native companies. This includes integration infrastructure, deep domain expertise, forward-deployed expertise, and agentic support. Ampersand announced the beta release of its AI integration agent, Andi. Andi helps developers with the implementation work required to get their products running in each customer's environment.

Ampersand's founders bring decades of integration experience to the problem. Ayan Barua was CTO and co-founder of Siftery, later acquired by G2, and then VP of Engineering at G2, where CRM and ERP integration work routinely consumed the majority of his engineering team's time. Lauren Long built Firebase Extensions at Google, connecting Firebase apps to third-party APIs at a scale that grew to billions of executions a day. The two spoke with more than 100 companies building integrations before writing Ampersand's first line of code.

"An agent is only as useful as the systems it can reach. MCP enables agents to describe a tool. It didn't address what happens at runtime, when tokens expire, schemas drift, and every customer's Salesforce looks a little different," said Lauri Moore, Partner at Bessemer Venture Partners. "Connecting an agent to a system of record is a demo. Keeping that connection alive across hundreds of customers, with writes you can't afford to get wrong, is much harder. That's what Ampersand is building."
