Our clients 🤝

Citadel, an increasingly expanding project overtime
We started working for Valuation Metrics, a Citadel Securities company in the fintech sector, six years ago when they were a small startup. We helped them to transition to being a big team after their acquisition in late 2021. A year ago, we were working 20 hours/week, and now, our team is dedicating 150 hours/week, to redesigning their UI/UX, working on web accessibility, architecture, performance, and overall security.

Our events 📅

Changing the venue for our Startup Grind events
June's event was our last one taking place at Movistar Center after eight years of doing events there. Movistar changed the rules, and from now on only free events are allowed. We're a paid event. We don't do it for profit, but to keep the quality standards high, and avoid people signing up and then not coming, just because it's free.

The summer events will be hosted at Talent Garden Barcelona while we look for a new home for our monthly event. If you want to share with us some venues, proposals, or crazy ideas, we'll love to read them. Thank you!

Our next event will take place on July 20th at Talent Garden BCN. We'll announce the speaker and open registration shortly. 
Stay Tuned!
