Case Study: Threekit launches a custom HubSpot theme in one day with Simple Machines Marketing

Threekit launches a full HubSpot theme in 1 day with Simple Machines Marketing

Threekit, an AI sales agent platform for manufacturers, needed to quickly launch a new marketing website on HubSpot Content Hub to reflect an updated product story. Their challenge was to translate a finished design system into a live, editor-friendly HubSpot theme without a traditional multi-week, costly development sprint that would delay their market advantage. They partnered with Simple Machines Marketing to solve this.

The solution from Simple Machines used an AI-native delivery approach with Claude Design and Claude Code. This allowed them to build and deploy a complete custom HubSpot theme with 36 modules and 7 templates in a single day. The result was a fully integrated site that preserved Threekit's design system and gave their marketing team complete editorial independence, bypassing the typical 4-6 week development timeline and potential cost of $15,000–$25,000.
