Program stucture

The founders got to know each other and the Rubik Hub team and had the first in-person workshops with Marius Lupu, Gautam Kumar, attended an Ask Me Anything session with Razvan Suta (Startup Wise Guys), Alex Burciu and Alex Chifu (Foretech Investments), and Emil Chichioi (Rubik Garage alumnus and co-founder of Bloomcoding). Also, the founders had their first pitches before the three months of acceleration.

Acceleration – During the next 3 months, the startups had intensive workshops with mentors from our community, group and individual meetings, and enjoyed benefits from our Startup Support Package, such as House of Startups and media coverage.

The startups pitched in front of an audience of over 100 attendees, attended in-person workshops held by Sebastian Gabor and Ruxandra Pui from Digitail and Andrei Dudoiu from SeedBlink, and had the opportunity to form authentic connections with investors, mentors and other founders.
