HubSpot Apps, CRM Cards & Integrations
Advanced HubSpot architecture, not just HubSpot setup.
When native workflows run out of road, we build the custom apps, CRM cards, and integrations that wire HubSpot into the rest of your stack, so the data sales trusts shows up where they work.
When the native tools run out of road.
HubSpot workflows are excellent until your real process needs logic they cannot express. Deal and line-item automation that has to preserve closed-won history. Renewal records that native rules quietly overwrite. Events that never mirror into Salesforce campaigns, so attribution falls apart. A second portal from an acquisition with no consolidated view.
That is where a custom app, a CRM card, or a microservice earns its place. We build the piece that native HubSpot cannot, connect it to the systems your team already runs, and document it so it does not become unowned tech debt the next person inherits.
What we build.
Custom HubSpot apps
Private and public apps that sync records, mirror marketing events into Salesforce campaigns, and run the logic native workflows cannot. Built with historical backfill so reporting reconciles from day one.
CRM cards
Custom cards that surface the data your reps need on the record they are working, pulled live from your own systems or a microservice, so nobody leaves HubSpot to find the answer.
Integrations and microservices
Vercel-hosted microservices and webhooks that connect HubSpot to Salesforce, billing, product, and the long tail of tools with an API, so the busywork runs without anyone copying fields by hand.
Deal and renewal automation
Custom line-item, deal, and renewal logic that replaces brittle workflow chains and preserves closed-won history, so your pipeline and revenue reporting stay trustworthy.
How an engagement runs.
A scoped build, not an open-ended retainer. The senior people who scope it are the people who write the code.
- 1
Map the seam
We trace the exact failure: where data drops, where history breaks, where attribution stops reconciling. You get a clear scope before anyone builds.
- 2
Build secure and observable
We design the app or integration with secure API auth, staging, and logging, working inside your SSO, access controls, and IT-security review, never around them.
- 3
Backfill and reconcile
We migrate historical records so dashboards match, then test the logic against your real edge cases before it touches production.
- 4
Document and hand back
You get architecture documentation and a maintainable build, so the work has an owner and survives the next team change.
Built to pass an IT and security review.
Custom code on your CRM should not become a snowflake nobody can maintain. We build for the people who have to live with it.
- Secure API authentication and least-privilege access, designed for your SSO and Microsoft permission model
- Proper staging, QA, and observability, not changes pushed straight to a live portal
- Documented architecture so the app is maintainable, not unowned tech debt
- Reversible, reconciled migrations that preserve data integrity and reporting history
The proof point.
For a B2B SaaS company, we built a custom HubSpot app that synced marketing events into Salesforce campaigns with historical backfill and ROI reporting, so attribution held from first touch to closed deal. For a global services firm, we shipped a multi-portal HubSpot Multi-Account Management build straight through IT-security blockers.
Untangling a HubSpot setup that sales has stopped trusting?
If sync gaps, broken automation, or a second portal are the real problem, start with the pillar and we will scope the fix.
Questions, answered.
- Yes. We build private and public apps that sync records and mirror marketing events into Salesforce campaigns, with historical backfill so closed-won and renewal history stays intact and your dashboards reconcile from day one.
