While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more
To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more

Written by the company
MentorStack is AI-native mentorship software for HR and L&D teams at mid-market companies. We help you retain your best people and get new hires productive faster through structured mentorship that actually runs itself. Every plan, including Free, ships with a native MCP server (94 tools, OAuth 2.1 plus scoped API keys) so you can run your mentorship program directly from AI assistants like Claude. No other mentorship platform offers this today. Smart matching pairs mentors and mentees across five dimensions: skills, goals, seniority, availability, and cross-functional diversity. Structured mentorship is associated with higher retention and faster ramp time (Gartner/Sun Microsystems study: 72% five-year retention for mentored employees vs. 49% for non-mentored employees). Beyond matching, MentorStack is a complete platform: goal tracking with milestones, meeting scheduling with AI-generated summaries, in-app messaging, an AI copilot, and an admin dashboard with board-ready reporting. Enterprise-ready from day one, honestly scoped: SSO/SAML and GDPR compliance ship now, plus HRIS integration with BambooHR, Workday, and SAP SuccessFactors. Unlike most competitors, our pricing is transparent and posted on our website, with no request-a-demo gate. Free plan for up to 10 users, Starter at $12 per user per month, Growth at $20, Enterprise custom. Built for 200 to 2,000 employee organizations with fast decision cycles. Founded in 2026 in Toronto, Canada.
