What is Dare to Scale

Dare to Scale is a 4-month accelerator for entrepreneurs across various industries who are eager to scale their already profitable businesses with the help of group workshops and 1:1 mentoring from Endeavor’s network members and PwC’s top consultants. The highly-customized program is aimed at nurturing Bulgarian late-stage startups in their quest to become globally competitive, growth-oriented, and resilient businesses.
Every year, the program partners, together with the Endeavor network, interview the shortlisted candidates and select a cohort of 6-12 aspiring companies to join Dare to Scale. Since launching in 2019, the program has nurtured 43 late-stage startups that have received over 400 hours in mentorship, 150+ introductions to partners and investors and have attended multiple networking events.
Dare to Scale is run by Endeavor Bulgaria – an affiliate of Endeavor, a global non-profit organization that supports high-impact entrepreneurs in over 40 markets. In its latest edition in 2022, the program was proudly financed by Postbank, Software Group, EBRD and BSMEPA.

What our Alumni are saying quote
“Dare to Scale helped us zoom-out of the day-to-day challenges, think strategically, define our ultimate objectives and start taking long-term bets towards them. The program also had a huge network effect for our company within the Bulgarian scale-up community! And most importantly, even during the COVID times, thanks to Dare to Scale, I managed to make some awesome new friends!”
Ruslan Leteyski
Founder, Checkout X
“Dare to Scale program is an excellent opportunity for early stage founders to learn from experienced entrepreneurs who have walked the path before. Besides various workshops that cover many of the aspects of running a company, you also get appointed a personal mentor, who will be supporting you during 1:1 sessions! Above all, it’s really up to you to take most of the program, the access to many successful entrepreneurs and peers.”
Oggy Popov
Founder, Prospecto
“Dare to Scale was very useful in a number of ways: 1) We made a number of improvements to our business, based on practical advice from mentors and speakers. 2) I upgraded my knowledge in each of the business areas we covered. This would serve me in the years to come. 3) Dare to Scale gives you access to a vast network of top experts and achievers in all business areas. Everyone was open to invest some of their time, talking to us.”
Svetoslav Dimov

“The great strength of Dare to Scale is that it has mentors who are business practitioners. These are entrepreneurs from the local community who have build successful companies and are business operators, not lecturers.”
Boyan Ivanov
CEO & Co-founder, StorPool Storage
“Dare to Scale proved to be an excellent opportunity also for non-software scale-ups, which is a rare gem to find in the sea of accelerators and programs. I believe the mentors and presenters at the workshops at Endeavor are the best you can find in our market and we highly value everything we learned. I believe Dare to Scale will change our business tremendously.”

We want to encourage every founder to participate in next year’s cohort as the value you will take, the people you meet and the opportunities you will have are priceless.”
