I look for 5 key things in a software development partner: great programmers, consistent quality, excellent value, a responsive management team, and a fun experience. Selleo is a solid 5 out of 5 by my standards.
Myron WeberCEO at Northwood AdvisorsTrust
More than 75%
of our business comes from recurrent projects and referrals made by clients and co-workers. We’d love to make traditional marketing and sales redundant.
I’ve asked them to complete projects that are new and they’ve always managed to do it. It’s important to have trust between partners, and they’re open enough for that to cultivate.
Peter LancasterCEO at Documobi LtdLONG-TERM RELATIONSHIPS
An engagement
with a client usually lasts well over 2 years. An average co-worker stays with us for almost 4 years. Our clients and collaborators appreciate long-term relationships.
Selleo were always professional and surprisingly responsive. I would definitely recommend Selleo, and would not hesitate to work with them again.
STABILITY & DEDICATION
Over the last 5 years
we have operated with a low voluntary turnover rate of 4.2%. We serve our clients with stable dedicated teams with long track records of effective joint collaboration.
Selleo treats this project as if it was their own business. They are emotionally invested in what they’re doing, which, to me, is unique.
