About us

Plenit (formerly Jotelulu) is the Operating Platform for IT Service Providers. We help MSPs, ISVs, VARs, and IT resellers run, scale, and grow their businesses on top of our own sovereign infrastructure, with footprint across Europe and the Americas.

We are a European cloud platform with a clear conviction: digital sovereignty matters, and the IT channel deserves a partner that speaks their language, builds for their reality, and stays close to the ground. We are not enterprise-y. We are simple, pragmatic, and obsessed with our partners’ success.

Five years in, we are 130 people, four countries, and growing fast — which is exactly why we are bringing this role on now.

 
 We’re passionate about technology, but we’re also a bit geeky—we love Star Wars, video games, 90s movies, and pop culture. We work hard and with passion, but we also have a great time together. At Jotelulu, you’ll find a balance between work and fun, where teammates often become friends, and boredom is rare—there’s always something new, unexpected, and memorable happening.
