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 by Dutch 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.
Lesson Marketplaces only reveal their cultural limits in the wild — and traffic operations matter more than I had credited.
