AI Overview
Performance snapshot
Selleo is a nearshore custom software development firm with a broad portfolio spanning edtech, fintech, healthcare, and real estate, supported by 63 reviews across four platforms dating back to 2016. The vendor's profile is predominantly Strong across technical execution, communication, and client satisfaction, with the overwhelming majority of reviewers praising code quality, responsiveness, and long-term partnership value. Two notable negative reviews — one a verified 0.5-star rating citing missed deadlines and poor deliverables, and another a 1-star rating referencing wasted budget on a widget redesign — introduce isolated but material concerns around consistency on smaller, design-focused engagements. Recurring patterns of multi-year client retention and MVP delivery success reinforce Selleo's positioning as a reliable extended-team partner.
