Ampersand raises $15M to connect AI agents with legacy enterprise software
Bessemer Venture Partners led the Series A for the San Francisco startup building read-and-write plumbing between AI apps and systems like Salesforce and NetSuite
Enterprise AI has a plumbing problem, and Ampersand just raised $15 million to work on the pipes.
The San Francisco-based developer platform closed a Series A round on October 6, 2026, with Bessemer Venture Partners in the lead. The pitch is simple to say and hard to build: let AI applications actually work inside the creaky business software companies already run on.
The round and who wrote the checks
Bessemer headed the financing. Returning backers Matrix and Flex Capital also participated.
The round brought in some new names too. Yelp and Mana Ventures joined as fresh investors.
With the new capital, Ampersand’s total funding now sits at approximately $19.7 to $20.7 million. The company was founded in 2022.
Its previous round was a $4.7 million seed led by Matrix in April 2023. The Series A is more than three times that size.

What Ampersand actually does
Ampersand builds infrastructure that lets so-called agentic applications perform read and write operations inside systems of record such as Salesforce and NetSuite. Agentic, in this context, means AI software that takes actions on its own rather than just answering questions.
Enterprise systems are rarely used out of the box. Companies customize them heavily, so one firm’s Salesforce setup can look almost nothing like another’s.
Ampersand’s focus is on deeper integrations that handle those customizations. The company positions this against traditional integration Platform as a Service tools, known as iPaaS, which tend to offer broader but shallower connections.
Meet Andi
Alongside the funding, Ampersand has announced the beta launch of Andi, an AI integration agent.
Andi is designed to help developers with per-customer implementation work. That covers the tedious, customer-specific configuration that makes data synchronization actually function in a given company’s environment.
Why the timing matters
Ampersand’s goal is to connect legacy systems of record with newer AI tools rather than replace them. The funding also lands as the broader sector moves toward standardized protocols for how AI systems interact with other software.
