Comparison
MentorStack vs Guider
Guider is sold through a call and a demo, so decide how much vendor contact you want before you compare features.
Guider is better for enterprise L&D teams that want a demo-led vendor relationship, a named account team, or mentoring bundled into Thrive's wider learning suite. MentorStack is better for lean People teams that want to see the price and launch the same day without booking a call or running a structured enterprise implementation.
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. As of 2026-08-11 it had been acquired by Thrive in July 2025 and sat alongside Thrive's learning and communications products, though Thrive stated it would continue developing Guider as a standalone product. Pricing was not published, and the buying process started 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 already run a mentoring pilot or program by hand and it is reaching the limit of what one coordinator can carry.
- You want to see the price and launch the same day without booking a call.
- 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 did not publish pricing when we last checked on 2026-08-11, and its buying process started with a call and a custom quote. Confirm current terms with Guider directly. MentorStack publishes $12 per participant per month, or $10.20 billed annually, with a Free Pilot for up to 10 participants.
- 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-participant 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?
- Guider lists Microsoft Teams and Outlook among its integrations, alongside Slack, Workday HCM, and BambooHR. MentorStack integrates with Slack and Teams on the Starter plan and above. On Growth, BambooHR is validated and Workday and SAP SuccessFactors adapters are available for validation with your tenant.
- Can I run reverse mentoring in MentorStack?
- Reverse mentoring is one of MentorStack’s supported formats, where a junior employee mentors a senior colleague. It is available on every plan including the Free Pilot, alongside one to one, group, and peer circle formats, and you can run several formats at once within a single program.
- Was Guider acquired?
- Thrive announced its acquisition of Guider in July 2025, and said it would keep developing Guider as a standalone product, as of our last check on 2026-08-11. Confirm the current structure with Guider directly. Whether that matters depends on whether you want mentoring inside a wider suite or as a focused tool. MentorStack is independent and does one thing.
