How Japan’s 220-Year-Old Contractor Is Rolling Out AI Across A 20,000-Person Workforce
Description
"We don't see the real costs of AI."
That's Jean-Marc Frangos, ex-BT in Silicon Valley, now running AI at Shimizu, one of Japan's "Big 5" contractors, founded in 1804.
We sat down with him to unpack how a 220 year old builder actually rolls out AI across a 20,000 person workforce.
The playbook, not the hype:
✅ Start with your data, not the model
✅ 5,000+ staff on one AI platform in ~7 months
✅ When the subsidies end, undisciplined teams get hit "like a ton of bricks"
