Yolk HubSpot
Yolk builds software on top of HubSpot — custom-coded workflow actions, CRM extensions, and integrations for teams that have outgrown what the marketplace offers.
The HubSpot marketplace covers the common cases. We build the ones it doesn't.
If your process needs a workflow action that runs real code, a card that surfaces outside data on your CRM records, or a two-way sync with a system that has no native connector — that's the work we do.
What we build on HubSpot
Custom-coded workflow actions
Real code inside your HubSpot workflows — custom logic, external API calls, and data transforms that go beyond the built-in actions.
CRM extensions
UI extensions and CRM cards that put data from your other systems right on contact, company, and deal records.
Integrations & two-way syncs
Connections to the tools the marketplace doesn't cover, built directly on the HubSpot API and kept in sync in both directions.
AI agents
Agents for enrichment, research, lead scoring, and outreach that work your CRM data around the clock.
Client portals & reporting
Portals your clients log into and custom dashboards for the questions HubSpot's built-in reports can't answer.
How we work
Direct with the founder
You work with Nick, Yolk's founder, from first call to final commit. No account manager, no handoff to a junior — the person who scopes your project is the person writing the code.
Fixed scope, fixed price
Projects are scoped and quoted up front. No hourly billing surprises.
You own everything
Code, documentation, infrastructure — everything we ship is yours when the engagement ends.
Yolk is based in Utah (US Mountain Time) and works with teams across North America.
