A New York headquarters built to develop autonomy at the speed of software.

Fresh off an $8.5M raise to scale the development of physical AI, the next move is a home base that keeps pace. This is a curated set of 15 full floors across the Flatiron and Midtown South corridor, the same submarket now absorbing the majority of New York's AI and growth-tech leasing. Right-sized, largely furnished, and anchored on Union Square. Start with the market read, then the map, then the spaces.

01 · The market, in brief

Where Manhattan office stands, Q2 2026

A tight read for Antioch: availability is tightening, pricing is firming, and the demand is being led by exactly your cohort. Growth-tech and AI tenants are driving the quarter, and they are concentrating in Midtown South.

The quarter was demand-led, and the tech cohort is the through-line, from Series A right through the growth stage.

Sublease inventory has fallen back under 11M SF from a 23M SF peak, so landlords are holding firm for direct deals and concessions are compressing. Tech and media requirements in the market total 8.8M SF, and 22.1% of that is AI tenants specifically. For a company at Antioch's stage, the read is simple: the space you want is getting leased, and the best-priced full floors move first.

The set on the following pages sits deliberately in the Flatiron and Midtown South core, the center of gravity for that AI demand. Asking rents in the set run from $58 to $115 per SF, which brackets the Class B to trophy range for the submarket and keeps real optionality on budget.
