The story behind AceOn

What started as a non-profit accelerator for start-ups and traditional businesses turned into complex accelerator program with exceptional program, mentors, and speakers. Back in 2019, we organised our first accelerator under #accacelife civic association and since 2023, we work together with ZAKA VC fund.

We continue on our journey providing ambitious founders the opportunity to further develop their businesses, support entrepreneurship and deliver insights into various start-up “must-know” topics such as fundraising, valuation, business development, marketing, founder vesting, design thinking and more.


Created by skilled entrepreneurs and start-up enthusiasts from advisory & BPO company Accace, together with ZAKA VC fund, our accelerator program is designed to turn entrepreneurs' ideas into successful businesses.

The world-class accelerator consists of two programs – Spring Accelerator and Autumn Accelerator that can take place either online or offline. With a diverse team of skilled mentors and experts you can get support and first-hand insights into finance, business development, marketing and more.

With a long history of helping and guiding start-ups, we have helped dozens of European start-ups to grow and shine.

AceON start-up accelerator was perfect for Flyer’s Guard. The remote evening sessions fit my schedule, and I learned a lot without feeling overwhelmed. The contacts I made turned into valuable business partnerships. Plus, their free consultations after the program are a great bonus. Highly recommend!
