HubSpot UI extensions that pull external data into your CRM records, without leaving HubSpot.
Cards render natively inside contact, deal, and company records. Your team sees phone enrichment, customer health scores, billing data, or product usage pulled from any external system, right inside the record they already work in.
What I build:
- CRM cards showing external data on contact, deal, or company records
- Interactive cards with button actions (log calls, create tasks, push data)
- Serverless backend functions, no exposed credentials, no separate server
- Phone enrichment cards (FullEnrich, Apollo, Clearbit)
- Customer health dashboards from your product database
- Billing and subscription data from Stripe or your internal app
- Any custom integration between HubSpot CRM and your stack
Built with: HubSpot UI Extensions SDK · React · HubSpot CLI · Private Apps
Every card deploys as a private app to your HubSpot account. No third-party access, no shared infrastructure. Message before ordering if your use case involves multiple object types or complex data sources.

FAQ
What exactly is a HubSpot UI extension?
A UI extension is a custom React card that renders natively inside HubSpot CRM records — contacts, deals, companies, or tickets. It looks and behaves like a built-in HubSpot feature. Unlike iframes, it has direct access to CRM context, object IDs, and properties.
Does my team need to leave HubSpot to use it?
No. The card lives inside the CRM record. Data is fetched in the background via a serverless function. Your team clicks a button and sees the result, all within HubSpot.
Will it connect to my existing system or API?
Yes. The serverless function can call any HTTPS API — your internal database, Stripe, PostHog, FullEnrich, or any other tool. API keys are stored as HubSpot secrets, never exposed to the browser.
What do I need to provide to get started?
Access to your HubSpot portal (partner invite link will be provided) and the API endpoint or documentation for the external system you want to connect. I handle all the development and deployment.
