Top 10 AI Consulting Companies in 2026

LeewayHertz started back in 2007, quietly spending close to two decades building core software long before artificial intelligence became a constant boardroom topic. Things shifted in a big way in 2024 when The Hackett Group acquired the firm. That move opened doors to massive enterprise relationships while letting them keep the hands-on, engineering-first mindset they were known for. Rather than treating AI like a tacked-on afterthought; which a lot of agencies end up doing; they built their own flagship platform called ZBrain. It is designed specifically to help companies figure out real AI use cases, map out the underlying technical architecture, and actually get those models live into production.
