Comparison
MentorStack vs Guider
Guider sells to enterprise People and L&D teams, with AI-based matching, live reporting dashboards, and support for peer, reverse, and cross-location mentoring. It was acquired by Thrive in July 2025 and now sits alongside Thrive's learning and communications products, though Thrive stated it would continue developing Guider as a standalone product. Pricing is not published: the buying process starts with a call.
Guider is the better choice for: Enterprise L&D teams who want a demo-led vendor relationship, and organisations already buying Thrive's wider learning suite.

Pick Guider if
- You want bundled implementation support and a named account team as part of the deal.
- Your procurement process expects a custom enterprise contract rather than a published list price.
- You already buy Thrive's learning suite and want mentoring consolidated into it.
- You need cross-location mentoring across a large multinational footprint.
Pick MentorStack if

- You want a native MCP server so program data is reachable from Claude or another AI assistant.
- You are a lean People team without the time for a structured enterprise implementation.
Common questions
- How much does Guider cost?
- Guider does not publish pricing. Their stated process is a 30-minute call from which you leave with a custom quote. MentorStack publishes $12 per seat per month, or $10.20 billed annually, with a free plan for up to 10 users.
- What is the best Guider alternative?
- If the thing pushing you to look is that you cannot see a price before booking a call, MentorStack publishes per-seat pricing and lets you launch without talking to anyone. If you specifically want bundled implementation support and an enterprise account team, Guider is built for that and MentorStack is not.
- Does Guider integrate with Microsoft Teams?
- Yes. Guider lists Microsoft Teams and Outlook among its integrations, alongside Slack, Google Workspace, Workday HCM, and BambooHR. MentorStack integrates with Slack and Teams on the Starter plan and above, and with BambooHR, Workday, and SAP on Growth.
- Can I run reverse mentoring in MentorStack?
- Yes. Reverse mentoring is one of the supported formats, available on every plan including the free tier, alongside one to one, group, and peer circle formats.
- Was Guider acquired?
- Yes. Thrive acquired Guider in July 2025 in a multi-million-pound deal and folded it into a combined learning, communications, and mentoring platform, while stating it would keep developing Guider as a standalone product. Whether that matters to you depends on whether you want mentoring as part of a wider suite or as a focused tool. MentorStack is independent and does one thing.
