What we ask for:

Why ReaktorX?

We thought that the current acceleration model is broken.

So we started asking founders what exactly they would expect from an acceleration program. We collected feedback from former cohorts, serial entrepreneurs, total beginners and early-stage founders and crafted the format you see today.

Take over the region today.

Start from CEE, grow globally with us.

No matter where in CEE you're from, you can apply to ReaktorX. Our program takes place in a different country every single batch, with the winning team of the program being the host country.

Build the next big thing.

We support global vision and high ambition founders.

You're an entrepreneur, and you see the world in a different way. You have a vision for the future, and you want to build something that will change lives. We believe in your vision. And we want to help you take your company from dream to reality by giving you the tools and resources to help turn your big idea into reality.

Get more hands on deck.

Experts and helpers standby whenever you need them.

Threre are a lot of building blocks to put in place when building a startup. Sometimes you just don't have the bandwidth or know-how to do it all on your own. The best way to help is to provide experts to guide you in a specific area and helpers that can hop on and take some of the workload.

Grow the way you know.

You decide what to focus on during the program.

Every startup has different needs, some have to focus on sales now, others on product or validation. We structure the accelerator on a 1-week sprint framework, with a total of 9 weeks for the entire program. Decide on your focus for each upcoming sprint with your lead mentor.

What founders say about ReaktorX

I 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.

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. One of the best tips that Uldis gave me ( which I want to keep to myself) influenced one of the best decisions I have ever made.

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.

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, what we do, and what we want to achieve. Thanks to the support of the entire ReaktorX team, as well as our hard work, we managed to redefine our goals and consistently implement them.

"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, supporting BuyerMind's growth."

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. 😅 Im my opinion, ReaktorX is the best accelerator in CEE.

Starting Renderro was one of the biggest changes of my life. And one of the first steps toward this change was joining the ReaktorX. There were problems that my previous experience couldn't provide me with solutions, all revolving around those questions: "How to transform your idea into a solution that helps people? How to make a product out of it? Could this idea be changed into a business?". I knew I needed answers. And back then the best place to find those answers was in the ReaktorX.

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.

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

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

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 with whom we began to work thanks to their mentorship program. He shared his extensive experience and gave us a number of valuable pieces of advice regarding business strategy, as well as helped us to form a go-to-market strategy.

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 at the early stage we were in. 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. The best part? Months after demo day, they're still in our corner, supporting BuyerMind's growth."

I'm a seasoned entrepreneur (twice regular business, once start-up) 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. Currently, we are challenging the Youth Travel market. We expect to have a booming growth in the post-COVID times.

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.

What is ReaktorX?

ReaktorX is an acceleration program for CEE founders in their first year of activity. The program is created and supported by SMOK Ventures, Creative Motion and Vestbee.

Who can apply?

Any founder from Europe or CEE region with a startup in its early stages. What does early stage mean? You either have a MVP, some validation (either through traction or research), or a validated model in other markets. At this stage, we care more about the team than anything else, so in your application please tell us more about your team structure.

How can I apply?

Scroll to the top of the page and click Apply.

What is the aim of the program?

Take your startup through validation, product-market fit, go-to-market strategy and more and get you ready for your first investment round.

How does the application process look like?

ReaktorX crew reviews the applications and startups that make it to stage two are notified via email. Calls are scheduled with all the teams and final decisions are announced before the program starts.

What's going to happen during the program?

Once you are accepted, you will be assigned your own private lead mentor who will help you develop your product on a weekly basis.
During the last week of the program, we are going to organize ReaktorX Demo Day where each graduate will pitch their startups to investors, journalists and fellow founders.

What tools and resources do you provide?

Except experts, helpers and mentors we also provide a growing database of courses, books, videos, templates (especially financial ones) and software tools to make your journey clearer.

How long will the program last?

9 weeks.

What will happen after I graduate?

That’s entirely up to you. We are going to introduce you to programs, business angels and VC’s who can help you with your next next steps.

Who are the mentors?

Mentors are seasoned entrepreneurs hand-picked by the ReaktorX crew.

How do we match startups with mentors?

In short: based on skills, startup requirements and personality match.

Why do you take equity in my startup?

We believe that by taking equity, we will be able to filter out people who are not thinking seriously about their business. Building a company is hard work and a huge commitment. We need to be sure you are serious. Taking equity also helps with your evaluation, having your startup evaluated at 500K EUR from the first year.

What is of equal importance, ReaktorX is a private acceleration program not funded by the European Union, PARP or any other public institution. We are proud to be independent. Because of that we can focus only on the important stuff like getting you though customer development, your MVP, towards a scalable business model and funding to secure future growth of your startup. No paperwork bullsh*t, only hard work on your company matters.

Can I still join if I don't want to give away equity in my startup?

No 🙂

I can't make it this year. When is the next batch?

We organize two batches a year, usually one starts in February and ends in May and the second one starts in September and ends in November.
