72% of culture initiatives fail. Yours doesn't have to.
Most organizations try to build culture through one-off programs. Mentessa builds it where it really lives: in the daily connections between your people.
It's not a program. It's a pattern.
And most organizations are stuck in one that looks like this.
TALENT
You have the talent, but it’s not shared.
KNOWLEDGE
Key knowledge doesn’t transfer.
IDEAS
Same ideas, different quarter.
CULTURE
Nothing changes, no matter what you try.
You’ve tried values statements, training, and team-building.
But culture isn’t what you say at the all-hands. It’s what people naturally do on a Tuesday afternoon: who they call, what they share, and whether they reach across departments without being told to. The organizations that get this right don’t train their way there. They connect their way there.
Culture is a new hire getting help from someone they’ve never met.
Knowledge is shared
A senior account manager debriefs a customer meeting with a junior colleague and the insight spreads before anyone has to ask.
Onboarding that sticks
A new hire finishes onboarding training and gets introduced to a mentor the same week. They see the value of learning and growth before their first 30 days.
Collaboration just “happens”
People from different departments come together on a project, leveraging each other’s expertise to build something faster.
Impact you can see on a P&L
You share a live report with your CFO showing the number of mentoring connections, learning sessions, and growing employee satisfaction.
Led by expertise. Driven by technology.
The only learning culture partner that combines both. From day one.
Expert Program Design
We co-design your learning culture program with goals, criteria and metrics using a framework refined across 100+ programs.
Award-Winning Platform
Our platform integrates with where your team works with intelligent matching, progress tracking, and GDPR compliance.
Ongoing Facilitation
We ensure mentoring sticks with ongoing check-ins, program analytics and support when you need it.
From strategy to a daily practice
Culture isn’t a buzzword. It’s how your team shows up.
Your culture, mapped
We start with your unique goals. A strategy sprint with your leadership team aligns the program to the outcomes you’re already measuring.
A platform that weaves into the workday
Mentoring, networking, buddy, and peer programs on a platform built for participants. Calendar integration, appointment booking, and a member directory that makes hidden expertise findable.
Momentum that compounds
Besides our platform, we stay involved with ongoing check-ins, program analytics and support so your program keeps compounding instead of stalling after a few months.
“Scales to 100% of our employees with no additional effort.”

Evica Kuc Head of Employee Growth OTP Bank Exactly the right technology for our community of mentors. We can use the intuitive platform to network the founders of tomorrow with the right experts. That saves us a lot of work and makes us very efficient.
Sophia Kuhl Managing Director HHL Digital Space Both the preliminary work and the implementation were very professional and we look forward to further cooperation.
Stefan Loibl Co-founder & CEO Immocation Masterclass Traditional approaches to learning are too slow and disengaging, hindering innovation and productivity. Mentessa provides a solution to build a connected learning culture, increase employee engagement, and improve overall wellbeing.
Mentessa creates real leverage by integrating exchange and belonging directly into everyday work — making growth scalable in the first place.
When we learn from and build on the ideas and skills of others, we create an inclusive work culture in which everyone can develop continuously and flexibly. This helps to react faster to change, to innovate, and ultimately to find more fulfilment at work.

Your questions, answered
What makes this different?
Most teams try to change culture at the level of ‘knowing’ through values statements, and one-off training. Mentessa changes it at the level of ‘doing’ to directly impact behavior change that compounds across your organization.
How is this different from buying mentoring software?
Software without strategy doesn’t last. Mentessa is the only partner that combines strategic advisory with an award-winning platform. We design around culture goals, not features.
What results should we expect?
Behavior change starts within weeks. Measurable culture shifts from engagement to productivity and retention are seen within 3-6 months. We track it with you through monthly check-ins and program analytics.
We’re a large organization. Can this scale?
25,000+ employees across 100+ programs. The platform handles matching, scheduling, reminders, and reporting. The facilitation layer means HR doesn’t become the bottleneck.
What does working with Mentessa look like?
That depends on your needs. Starting new? We run a strategy sprint, design your program, and launch it with you. Already have a program or switching providers? Get the platform only and add advisory if you need it. Most teams are live within 1-2 weeks.
Do we need to replace our existing tools?
Not at all. Mentessa integrates where your team naturally works, from Microsoft Teams, to Slack, Discord, calendar integrations and everything in between.
Your team already has the expertise. Let’s connect it.
After 100+ programs and 25,000+ employees connected, we know what makes culture a verb. Talk to one of our experts to explore how we can make it work for your organization.
