Testimonials from previous participants

“I took part in the Paysafe Hackathon 2018.  The experience was great - I believe Hackathons are the best place for meeting new people, challenging yourself to build something worthy in a limited amount of time and validating your ideas.

 We managed to build a working application from the ground-up and got a lot of positive feedback about our idea and implementation. The biggest upside for me was that I met my future manager at the hackathon, who told me that there are active openings at Paysafe and 2 months later I was part of the company.

I would definitely recommend taking part in a Paysafe Hackaton. Gather a team, come up with an idea and sign up.”

Anton Sankov, Paysafe Hackathon, March 2018

“Our team decided to join Paysafe Hackathon 2018 because the topics seemed challenging and seeking innovation.  It was a great fun overall and we would recommend it.

In fact, we have already shared with a lot of friends what a wonderful time we had during the event - we met great people and had the opportunity to develop technical solutions to interesting challenges.”

Team “Tech Valley”, Paysafe Hackathon, March 2018

“The experience that you have during the Hackathon is unique – there are always surprises, funny moments, positive people and mentors who are always ready to support you and of course - a lot of challenges.

I had the chance to participate in 2 Hackathons organized and hosted by Paysafe – in 2018 during the Next Block Conference and in the Paysafe Hackathon 2019.

For me the hackathon is not only a competition, but also an opportunity to show creativity while dealing with a social problem and I am sure that I’ll take part again in similar events!”

Nikolay Angelov, Next Block Hackathon, September 2018 and Paysafe Hackathon 2019, August 2019
