Don't take our word for it

It’s nice to come to London to attend the conference in person. I’m always excited about the ZIO ecosystem, and it’s really amazing to be here and see all the people and amazing vibe around this community.

Alex Garella

I get to meet all these people I speak to on Discord the whole year. There are lots of amazing talks, it’s an amazing opportunity. I really appreciate the organizers for doing it.

Jaroslav Regec

It’s really great (...) meeting the authors of the libraries that we use, getting the information, and learning about libraries that otherwise we wouldn’t have known about.

Andreas Pauley

I've enjoyed all the talks, and I think the quality throughout the two days has been amazing.

Avinder Bahra

I had a great time at the Functional Scala. It was an amazing experience. It's like working remotely on the same project for a few years and finally having a chance to speak in person, but the project is called scala ecosystem and your team is the whole scala community. Hope to see you all soon.

Kasper Kondzielski

I had a blast at Functional Scala 2022. Good to meet so many fellow Scala developers and OSS contributors in person. A lot of feedback, ideas... I go home with renewed motivation.

Pierre Ricadat
