Why it matters
Most spending still happens in physical stores, and operators lack real-time intelligence. A $170M raise into Physical AI signals growing investor appetite to wire up offline retail.

Spencer Hewett (Spencer Hewett (@SpencerHewett)) said his company RADAR has raised a $170 million Series B, valuing the business at more than $1 billion, in an announcement on X.
Hewett framed the round around a bet on what he calls Physical AI. "We believe Physical AI can transform the 80% of global commerce that still happens in stores," he wrote, adding that retailers lose an estimated $1 trillion each year. The post linked to a video with more context.
In the post, he thanked investors including @nimble_partners, @gideonstrategic, @AlignVentures, @sound_ventures_, and @ycombinator. He also cited customers such as @AEO, Gap Inc., and @OldNavy, and credited the RADAR team.
RADAR, a physical retail data infrastructure startup led by Hewett, builds a hardware-enabled SaaS platform that uses overhead sensors, software, and AI-powered analytics to locate products in stores and deliver item-level analytics. According to the company's website and hiring materials, RADAR is deployed across 1,400+ stores with retailers including American Eagle Outfitters and Old Navy, processes tens of billions of real-world events every day, and delivers 99%+ accuracy in complex environments. The company describes its system as powered by RFID and positions its stack as foundational infrastructure for the physical economy.
Beyond the amount and valuation, the X post did not detail how the new capital will be used. RuntimeWire will update as more information becomes available from RADAR or additional disclosures about the round.
