I worked with CELSO both to create ASPA’s presentation website and to develop a complex application through which we manage and promote for adoption the dogs in our shelters. The collaboration was seamless, and together we achieved even more than we initially set out to accomplish.

General Manager ASPA
The Municipality of Bucharest

The team at CELSO exceeded all expectations when it came to building our website. We've asked for many custom functions which they built fast and at a very good price. Also, they provided expertise whenever we were at doubt about various design, content or functionality issues.

General Manager
SACHE Foundation

CELSO built for our company many custom solutions but the most complex was a CRM that includes many specialized functions - this alone allowed us to save thousands of euros yearly by discontinuing the subscription based CRM that we used before. Strongly recommend this team, they work quickly and accept any challenge!
