Thoughtworks vs Quantiphi: overview
Thoughtworks
Thoughtworks was founded in Chicago in 1993 and has roughly 10,000 staff. Apax Partners took it private in a deal announced in August 2024 that valued the company at about $1.75 billion. Its AI work grows out of software and data engineering, so strategy engagements focus on where AI changes how software is built and how data products are run. In March 2026 it launched an AI joint venture with Teneo, a New York advisory firm, to add a stronger business-advisory side. Its public Technology Radar, a twice-yearly review of tools and techniques, is a free way to judge how it thinks before you hire it.
Quantiphi
Quantiphi was founded in 2013, is headquartered in Marlborough, Massachusetts, and has around 4,000 employees. It holds top partner tiers with Google Cloud, AWS, and NVIDIA, according to its own materials, and ISG named it a Leader for AI and machine learning services on Google Cloud in its 2024 Provider Lens report. Its strategy offer is mostly a front end to engineering: use-case discovery and roadmaps that lead into builds on those platforms. It makes most sense when the platform decision is already made.
