Data Coffee
Mar 2026 – May 2026
MCP server for a Dutch data/AI community — agent-native, no UI.
Invite-only MCP server for 荷兰数据群 — a 700-person Chinese data/AI professional community in the Netherlands. Members connect their own agents and call structured tools for coffee chats, referrals, and resource sharing. The entry filter is the product itself: if you can configure an MCP server, you belong.
Killed byTwo things. (1) Agent-native habits are still early — too few members had an MCP-capable client set up to actually use it. (2) I cooled on MCP as a delivery surface: the server stays resident in the agent context and burns tokens even when idle. Next form will be a plain REST API or a CLI.

ColleagueReferral
Feb 2025 – Feb 2026
A marketplace for cold referral asks.
Employees posted open roles at their company; job seekers asked for referrals directly. The pitch: lower hiring cost for companies, referral bonuses for employees, a faster signal for candidates.
Killed byDutch hiring runs on warm referrals — employees were reluctant to put their professional reputation behind strangers, so supply stayed thin. We were not a strong operations team; after exhausting agency contacts and our own network, traffic plateaued at 568 registered users. Ran in silent mode until the domain expired.
LessonMarketplaces only reveal their cultural limits in the wild — and traffic operations matter more than I had credited.
