The Challenge
A German food-tech company had built a sophisticated MySQL database containing rich customer data — purchase history, preferences, subscription status, and more. However, their marketing team had zero visibility into this data within HubSpot.
The result was a painful workflow:
- Manual CSV exports from the database
- Constant switching between systems
- Marketing campaigns based on outdated data
- Customer support lacking real-time customer context
What We Built
We developed a lightweight integration using Cloudflare Workers and Hyperdrive that synchronizes MySQL data to HubSpot with minimal infrastructure overhead.
The solution features:
- 10-minute sync cycles ensuring near real-time data freshness
- 12 database tables synchronized to HubSpot
- Incremental updates via KV storage tracking last sync timestamps
- Automatic association handling maintaining relationships between records

Key Results
The integration delivered immediate impact across multiple teams:

- Enhanced customer support — Support team has real-time visibility into customer status
- Marketing segmentation — Campaigns now target customers based on actual purchase behavior

Impact
The marketing team can now create segments based on:

Customer support sees the complete customer picture without leaving HubSpot, reducing resolution times and improving customer satisfaction.
