Client testimonials reference work with Rolls Royce, where repeat business demonstrated strong performance. A Director of Digital Strategy noted that BairesDev's resourcing and account management enabled faster product delivery while reducing costs. A VP of Engineering at another client highlighted BairesDev's ability to integrate seamlessly with internal teams and meet full-time employee expectations. An SVP managing LATAM operations credited BairesDev's staffing process and nearshore timezone alignment for faster execution. A seven-year client relationship was cited as evidence of resource quality and management flexibility.

How they work

The engagement process begins with an exploration call to discuss team structure, success criteria, timescale, budget, and required skill sets. Within days, BairesDev finalizes project specifications, agrees on an engagement model, and selects and onboards the team. Teams are described as ready in two weeks. Once agreed on milestones, work begins immediately with progress tracking, regular updates, and continuous adaptation to changing needs. Client retention stands at 96%, with average engagements lasting over three years. The company emphasizes timezone alignment for nearshore teams and English-language communication.
