Deloitte vs Softermii: overview

Deloitte

Deloitte was founded in 1845 in London and is now the largest professional services network in the world by revenue and headcount, employing approximately 470,000 people as of 2025. Its AI and Insights practice covers generative AI, agentic AI, and edge intelligence specifically, backed by the Deloitte AI Institute for research and thought leadership. At this scale, generative AI consulting is one service line within an enormous global professional services firm, not a dedicated boutique.

Softermii

Softermii has run out of Los Angeles since 2014, with reported staff between roughly 88 and 120. Its core identity is custom software and platform development; generative AI consulting is a newer, growing line rather than the founding specialty. Clients get a partner that builds the full surrounding product, not just a generative AI recommendation, at the cost of the depth a dedicated AI-only consultancy can offer.
