What we do

Deep integrations for the products you build

Ampersand is a developer platform for building and running integrations between your product and your customers’ business software. We help B2B SaaS and AI teams connect to CRMs, ERPs, and other applications with bi-directional data sync and configuration that adapts to each customer.

Build integrations in code

Define what your product reads and writes with a declarative framework that fits into version control and CI/CD. Use managed authentication, scheduled and on-demand reads, writes, and a proxy API to connect your product to your customers’ tools.

Adapt to each customer

Support standard and custom objects and fields, with field mappings that reflect how each customer runs their business. Embed connection and configuration experiences in your app so customers can set up integrations themselves.

Keep integrations running

Let Ampersand handle token refreshes, retries, rate limits, and historical data backfills. Use logs and dashboards to understand sync activity and troubleshoot issues as your customer base grows.

Our thesis

The next generation of software needs to work together

New products and AI agents depend on data held in established business systems. To be useful in a customer’s day-to-day work, they need to understand that data and send updates back. Reliable integrations are part of the product experience.

Every customer’s setup is different. Custom objects, fields, and workflows make connecting two applications an ongoing engineering challenge. We believe developers should have infrastructure that handles that complexity, so they can focus on what makes their product valuable.

Frequently asked questions

What does Ampersand do?

Ampersand provides infrastructure for native product integrations: the connections your customers use inside your app to link their existing business software. It helps your product read customer data, write updates back, and manage those connections over time.

Who is Ampersand built for?

Ampersand is built for engineering teams developing B2B SaaS products and AI agents. It is especially useful when your product needs to work with customers’ CRMs, ERPs, and other business applications, including highly customized environments.

Which applications can I integrate with?

Ampersand’s connector library covers applications across sales, marketing, revenue, support, and more, including Salesforce, HubSpot, Marketo, and Microsoft Dynamics. Available operations vary by connector, so check the catalog for the systems your customers use.

Explore the connector catalog
How is Ampersand different from a unified API?

Ampersand lets you work with a provider’s own objects and fields, including custom ones, without fitting every customer into a single common data model. You define the data your product needs and let customers configure mappings for their own setup.

Can Ampersand support AI agents?

Yes. Agents can use Ampersand to read context from connected business applications and write results back. Managed authentication and integration infrastructure help developers connect agents to the systems their customers already rely on.
