Stride Consulting vs B12 Consulting: overview
Stride Consulting
Stride Consulting is a New York City-based software engineering agency founded in 2014 by Debbie Madden, with 51–200 employees, built around embedding senior engineers directly with client teams rather than staffing a layered account-management structure. It has extended that agency model into agentic AI with a proprietary '100x agent' for legacy modernization, and its client roster (Plated, The Daily Beast, Equinox, Gust) shows it can win named enterprise work at agency scale. For a buyer wanting an agency rather than a large SI, its senior-only staffing model is the clearest differentiator on this list.
B12 Consulting
B12 Consulting was founded in 2012 by a group of PhDs in Physics sharing a passion for complex problem solving, headquartered in Louvain-la-Neuve, Belgium with an additional Brussels presence, and roughly 35 FTE. It is an agency expert in artificial intelligence, data science, and custom software development, with a technical, research-adjacent culture reflecting its founders' academic backgrounds.
