Our Alumni Say

Sessions with our technical mentor, Serhiy Shelpyuk, demonstrated the importance and advantages of our product. Training the model on real legal cases ensures high-quality processing of legal terminology and context. And, of course, the power of networking. It is very important to exchange ideas, experiences, and challenges with other founders.

Enrique Prado, Inspira

With our mentor, we set a goal to secure at least one pilot client. However, thanks to the program’s experts and the work we’ve done, we now have a packed schedule of calls with potential clients for the next two weeks.

Denys Samofan, Rythmex

When we began expanding into other countries, we realized that we couldn’t follow the same approach everywhere. One of our goals in joining the accelerator was to gain experience in scaling a business. We’re also integrating AI tools into the platform to make learning more interactive and personalized for children. Challenger’s expertise has been instrumental in this process.

Natalia Limonova, GIOS

Working with our mentors was an incredible opportunity. We especially want to thank our business mentor Lev, who shared invaluable insights on building our company in the European Union. In particular, his guidance on setting up in Estonia gave us a clear direction — and we see this as our next step toward entering the EU market.

Vladyslav Kaliuzhka, Extra-Vision

So first of all we have managed to optimize our technical architecture of our product, and second of all I would like to mention that we have gained valuable insights about investments thanks to our mentors, colleagues and partners.

Ilona Didukh, Josti

Actually we are extremely happy to be the part of the program because we came to Challenger, we needed some technical advice and we definitely received it and even more. We received the mentor from business side who already did the exit and he just gave us a speed and some advice which economized months and maybe years for us to do the right actions.

Olena Kleiner, Salesdep.ai

In my opinion, Challenger is definitely one of the best programs I have ever seen according to quality of content and quality of mentorship. We applied to Challenger because we scale up and we wanted to get more professional advice on how to scale, because it is tricky to grow. We wanted mentorship, we got it fully. We are very excited with our business mentor, with our technical mentors. We are excited with the quality and level of the educational program.

Sergii Kravtsov, ConnectiveOne

“From the get-go of the program we had not a single line of code of the Intemper version two. We had hired our new CTO, our new developer and we were starting from a blank slate. Our first communication with the mentors was super helpful because we redeveloped our business model, our financial model and our go-to-market strategy at all. So, on a nutshell, it was super helpful, super insightful and super supportive.”

Alina Holovatiuk, InTempo

“I'm very excited about the mentors involved in this program and very happy with the one-to-one sessions. We have dramatically improved our pitching, business model, and valuation for our clients. So it's a biggest value part of your acceleration program.  Thank you for that!”
