Hi everyone, Kjell here. This is a "small" side project that I have been working on for a couple of months. The reason I started it was because I had to do cold outreach on another project that I was working on earlier this year. HubSpot was too expensive, so I hacked a small outreach tool together using Claude: Gmail + Google Sheet + Apps Script.

It worked quite well, but the script quickly grew complex, and it's not ideal to manage contacts in a Google Sheet. So I decided to build what I needed once and for all and I wanted to make it completely open-source and with a MIT licence.

In the link you can see the result. What started small has now grown into a full-fledged headless customer platform. It's all designed around MCP being a primary interface. Sure, it might be thin in some areas, but it works surprisingly well. Give it a spin and let me know what you think, appreciate all feedback either product or tech-wise. Here's a small 3 min video where I demo some of the features: https://vimeo.com/1204180225

Congrats on the launch! I am pretty sure every great dev has built a simple workaround for a task at least once before realizing how painful it is to maintain state or even manage contacts in a spreadsheet. Will give the repo a spin during my free time, great work open-sourcing this.

Thanks! Looking forward to hear what you think of it.
