About Mentors

“Our Mentors are real friends who give advice based on their talent and experience, not just utilitarian business contacts”.

Mentors at Catalyzer Startup Accelerator are genuinely interested in supporting startups and entrepreneurs. Even the most successful and busy mentors are supportive, and will spend time to answer questions. They give practical advice, provide feedback, make introductions and recommendations. Mentors are real friends who give advice based on their talent and experience, not just utilitarian business contacts. This culture makes us unique and different from other seed and startup accelerators.

Mentors have seen it all ! They have seen big exits and small businesses, profitable and train-wreck companies, fast growth and slumps, dream teams and disputes, and all types of great ideas and the worst crashes. Startups and startup businesses are unpredictable; you never know what surprises lie around the next corner. When you talk to mentors, whether you have good or bad news, chances are that they have seen the situation before. Their experience and understanding of the problem will enable them to make good predictions. Mentors at Catalyzer Startup Accelerator are exceptionally bright and talented, outspoken, straight-to-the-point and honest people. They make time for the startups and only do things that are good for startup businesses.

Mentors are entrepreneurs themselves and know anybody and everybody worth knowing in the startup scene. This makes them ideally placed for introducing you to the kind of people you want to meet. They also know who is sincerely helping you, who is genuinely investing, and who do not mean business.

For startups that are new to the markets, mentors are a great way to help you, establish your ground. You can build your network with the help of those who already know their way around. You can celebrate with them when things go well, and get encouragement from them during tough times. You could not ask for a better group of people to hang out with and build your startup business with a network of talented people.

Catalyzer Mentors and Advisors are experienced entrepreneurs, academicians and consultants. They volunteer their valuable time without compensation in order to give back to the entrepreneurial community and help nurture future entrepreneurs. Mentors and Advisors work with teams to provide impartial advice in their areas of relevant expertise.
