Common questions
- How much does Ten Thousand Coffees cost?
- 10KC does not publish pricing and sells custom enterprise plans requested through its site, so you cannot see a number before you talk to them. MentorStack publishes $12 per participant per month, or $10.20 annualized, with a Free Pilot for up to 10 participants and no sales call needed.
- What is the best Ten Thousand Coffees alternative for a smaller company?
- 10KC lists quote-based plans for up to 5,000 employees and for more than 5,000, so a smaller company cannot see a price before a sales call. MentorStack is built for mid-market teams, starts free at 10 participants, and publishes per-participant pricing so a smaller org can size the cost without a call.
- What is the difference between 10KC and MentorStack?
- 10KC leans toward breadth: many light connections across a large workforce, which is the right shape for a company trying to increase internal networking generally. MentorStack leans toward depth: a defined program, matched pairs, tracked goals, and analytics an admin reports on. They are solving adjacent but different problems.
- Does MentorStack work for large enterprises?
- It runs on unlimited participants from the Starter plan up, with reporting from Starter, and SSO, SAML, HRIS integration, and scheduled reports on Growth. That said, if your requirement is workforce-wide informal networking across tens of thousands of people rather than a structured program, 10KC is built for that shape and MentorStack is not.
