Learn moreI seriously doubt hiPets would even have taken off if it wasn't for ReaktorX. I won't list everyone who talked to me during my ReaktorX because I'm sure I'll forget someone, so I'll say collectively that Reaktor, thank you for bringing the best people who gave their time and shared their know how and experience with me.

Great organization, connection with mentors who were supportive at every step, ad hoc consultations with the best, intensive pitching sessions — all this resulted in a completely different approach and a look at our business. Thanks to the support of the entire ReaktorX team, we managed to redefine our goals and consistently implement them.

ReaktorX's mentorship was crucial in refining our business model and strategy — emphasizing assumption validation before development and facilitating connections that led to beneficial partnerships and funding opportunities.

How did ReaktorX help? By a very individual approach to our business case, but also creating great structure shared with other startups.

I'm a seasoned entrepreneur with lots of love for the Youth Travel industry. Despite being in the business for over 14 years, ReaktorX gave me a lot on shaping a start-up vs. a regular business. We expect to have booming growth in the post-COVID times.

ReaktorX helped me build my routine. I met my first business mentor in ReaktorX — Uldis Leiterts. Uldis is a serial entrepreneur with a history of successes but also failures — thanks to that we quickly hit it off. The knowledge, pieces of advice, and motivation that he shared with me have been bearing fruit up until today.

The ReactorX team just gets it. The program gave us exactly what we needed: honest feedback on early-stage development of our product, industry insights from successful founders, and network connections that actually matter. The best part? Months after demo day, they're still in our corner.

ReaktorX infused us with hands-on knowledge in an exceptionally supportive environment.

Based on the work done within the program, we were able to make an important product pivot, increasing the value of our product. Our special thanks to ReaktorX for the mentor who shared his extensive experience and helped us to form a go-to-market strategy.

The program opened my eyes to many relevant aspects of running a startup, though the most significant benefit of taking part in it was the network. I met fantastic people, including like-minded founders, mentors, and investors, many of whom I am still in touch with.

The program helped a lot along the way from advice (even harsh advice) to commitment, contacts, deep understanding and learning all the steps required to build and manage the "next big thing". People from ReaktorX and SMOK rock in so many ways even after the program ended.

Starting Renderro was one of the biggest changes of my life. There were problems that my previous experience couldn't provide me with solutions. How to transform your idea into a solution that helps people? How to make a product out of it? ReaktorX was the best place to find those answers.

When I joined ReaktorX in 2020 I had a lot of doubts and mixed feelings, especially when people I talked about it assumed that I would be a mentor and not participate in the program myself. 😅 In my opinion, ReaktorX is the best accelerator in CEE.

Quite surprisingly, the no. 1 value that I drew from ReaktorX were not the workshops. Sure, they were amazing and very well suited to what we needed. But it's almost nothing compared to the incredible network I got access to thanks to ReaktorX.

The ReaktorX team just gets it. The program gave us exactly what we needed: honest feedback on early-stage development of our product, industry insights from successful founders, and network connections that actually matter. Months after demo day, they're still in our corner, supporting BuyerMind's growth.
