What architecture plus information (a+i) does
Architecture Plus Information (A+I) is a strategy-led integrated design agency founded in 1996 in New York City by Columbia University graduates Brad Zizmor and Dag Folger. The firm provides architecture, interior design, and brand strategy services to enterprise clients, with a focus on workplace design, corporate headquarters, building and asset repositioning, and brand-integrated environments. As of September 15, 2025, A+I merged with global design firm Perkins&Will, with the New York studio becoming the second-largest in Perkins&Will's global network at 179 employees. Pre-merger headcount stood at 70+ professionals, with the firm headquartered in a 13,000 SF office in Manhattan's Flatiron District.
The firm's service portfolio spans several interconnected offerings: workplace and headquarters design (notable projects include Squarespace's 98,000 SF HQ, Equinox's 117,000 SF HQ at Hudson Yards, and TIDAL's first office); building and asset repositioning (theMART 4,000,000 SF for Vornado, PENN 1 225,000 SF, Hines' 168,000 SF HQ, Nuveen's Gardens at 780); brand strategy and identity (with proprietary sub-brands developed for clients including WorkLife, The Landing, and Office Hours for Vornado); and selective retail/hospitality and residential work. The firm's methodology is described as an investigative, information-driven approach that combines strategy, architecture, interiors, and brand design into cohesive solutions. Operating status post-merger is "acquired" — A+I now operates as a studio within Perkins&Will.
A+I operates on project-based professional services pricing with multi-year contract cadences. The go-to-market motion is enterprise field sales driven by direct senior-leadership engagement, with CEO Kate Thatcher and co-founders Zizmor and Folger driving business development through direct relationships, referrals, and industry recognition. Customer segments span technology and media companies, real estate developers and landlords (Vornado, Hines, Silverstein, Nuveen), retail and hospitality brands, and high-net-worth individuals. Geographic focus is primarily major US metropolitan markets (Northeast, Midwest, South, West) with selective international work (Peloton London studios). Leadership includes CEO Kate Thatcher (appointed 2020, Yale-trained), Chief Design Officer Sommer Schauer, and co-founders Brad Zizmor and Dag Folger, both now Managing Principals under Perkins&Will.

architecture plus information (a+i) competitors and assessment
Company assessmentBroad incumbents
- Perkins&Will: Global architecture firm and A+I's parent company post-September 2025 merger. Competed with A+I pre-merger for large workplace and repositioning projects; combined entity now competes across 20+ studios worldwide.
- HOK: Global architecture and engineering firm with major workplace practice. Competes for enterprise and developer-led projects at much larger scale than A+I, including building repositioning and corporate HQs.
- Gensler: Largest global architecture and design firm with deep workplace design practice. Directly competes with A+I for enterprise HQ and repositioning mandates but operates at vastly greater scale (5,000+ employees) and across all building types.
- Skidmore, Owings & Merrill (SOM): Iconic global architecture firm with significant workplace, commercial, and repositioning practice. Competes at the highest end of the market for landmark commissions that A+I also targets, though at much greater scale.
Direct peers
- Studios Architecture: NYC- and London-based architecture firm specializing in workplace design for tech and media clients. Direct competitor on enterprise HQ mandates with similar client overlap (Google, Facebook, Spotify) to A+I's Squarespace, Peloton, and TIDAL engagements.
- Rockwell Group: David Rockwell's NYC-based integrated design firm combining architecture, interiors, and brand storytelling. Closest direct peer to A+I given shared strategy-led, experience-driven approach to hospitality, workplace, and entertainment environments.
- Rottet Studio: Houston- and NYC-based interior architecture firm specializing in luxury workplace, hospitality, and residential design. Direct peer competing in the high-end corporate HQ and repositioning segment.
- M Moser Associates: Global workplace design firm with integrated architecture, interiors, and strategy capabilities. Direct peer in the integrated-design-for-workplace category where A+I competes.
- IA Interior Architects: Workplace-focused interior architecture firm headquartered in San Francisco. Direct peer competing for the same enterprise tenant-improvement and HQ commissions as A+I, though A+I differentiates via brand strategy integration.
Regional players
- Leo A Daly: US architecture, engineering, and planning firm with established workplace and commercial interior practices. Comparable in mid-market enterprise commissions though less focused on integrated brand-strategy design than A+I.
