AI Overview
Performance snapshot
DO OK is a Polish-based software development and IT staff augmentation firm with a strong track record across a diverse client base spanning Europe and North America. The vendor consistently earns high marks for technical versatility, communication, and on-time delivery, with the majority of detailed reviews returning perfect or near-perfect sub-ratings. One significant negative review from 2018 — citing missed deadlines, poor communication, and a buggy product on a large enterprise engagement — stands as an isolated but notable outlier in an otherwise positive review history. Overall, the pattern leans strongly positive, particularly in post-2022 engagements.
Performance breakdown

Project management & delivery
MixedThe majority of recent reviews confirm on-time delivery with well-defined milestones and cost adherence.

Communication & collaboration

Daily developer contact and seamless integration into client workflows are recurring positive themes, anchored by specific engagement details across several high-density reviews.
Reliability
