A+I is a strategy-led, integrated architecture agency offering design services from inception to completion. It was founded in New York City in 1996 by Brad Zizmor and Dag Folger. The firm’s name stands for Architecture Plus Information, a nod to its investigative approach and creative curiosity. 

For the last 30-years, A+I has been at the forefront of workplace innovation, harnessing information and creativity to design and build ambitious, amenity-rich headquarters for innovative organizations across the world. Some of its most well-known projects include PENN 1; PENN 2; the brand identity for the entire PENN District; and the branding of PENN 1’s signature restaurant The Landing. The firm is also behind the design of Le Truc for French advertising giant Publicis Groupe as well as the headquarters of Squarespace and Peloton. 

A+I believes that the physical environment is the most visceral way for a company to embody its values, reflect its ethos, and communicate its ambition, carrying culture and mission through times of change and transformation. The firm’s fully integrated studios create spaces that propel businesses and their people forward. 

On September 15, 2025, A+I became part of global design leader Perkins&Will. This partnership combines A+I’s strategy-led, data-informed, and brand-integrated design approach with Perkins&Will’s worldwide reach, deep expertise in sustainability, and legacy of design excellence. Together, they will set new standards for design excellence and impact.
