Crunchbase connector tools
The Crunchbase connector tools in Mark (Optimizely Agent Platform) provide AI-powered access to the world's most comprehensive dataset of companies, investors, funding rounds, and key business personnel. This integration lets you discover insights, track market trends, and identify opportunities through natural language queries in Mark.
After an administrator configures the Crunchbase connector on the Connectors page, the tools become available in Mark chat, agents, and workflows.
Complete the following steps to enable the Crunchbase Mark tools.
Obtain your Crunchbase API key
Go to Crunchbase, and complete the following steps:
- Log in to your Crunchbase account.
- Go to Account Settings > API Keys.
- Generate a new API key or copy an existing one.
Configure the Crunchbase connector
When you click Configure, Mark opens the Configure Crunchbase dialog. If the connector is not installed yet, an Install modal displays first. The dialog then has two steps: Settings, where you enter the details the connector needs to authenticate, and Tools, where you choose which tools to enable.
As a Mark administrator, complete the following steps:
- Go to Connectors.
- (Optional) Enter Crunchbase in the Enter name field, or use the Provider, Active Status, and Provider Type filters to find the connector.
- Click Configure on the Crunchbase tile.
Note The Install modal only displays if the connector is not installed yet. Installing adds the connector to your organization and makes its tools available. You install a connector once, for everyone.
- On the Settings step, complete the following, and then click Next. The app stores these settings and applies them to everyone in your organization.
- Enter your Crunchbase API key from the Obtain your Crunchbase API key section.
- (Optional) Toggle Advanced Endpoints on if you have access to premium features.
- On the Tools step, select the tools that users can use by default, and then click Save. Each tool displays its type, such as Read, Create, Update, or Delete. Use the search field to find a tool, or click Deselect all to clear the selection. Tools that you do not select still display on the connector's Tools tab, but remain disabled until you select them.
After you configure the connector, the Crunchbase tile displays Connect for you and for every Mark user in your organization. Click Connect to connect it.

- Be specific – Include relevant criteria like location, industry, funding stage, or employee count.
- Use filters – Leverage date ranges, amounts, and categories to narrow results.
- Iterate – Start broad, then refine based on initial results.
- Combine searches – Use organization search followed by funding round search for deeper analysis.
- Check data freshness – Crunchbase data is regularly updated but may have delays for recent events.
