Congratulations to Alexa Tonner, our Co-Founder and Chief Operating Officer, for being named to ADWEEK’s inaugural Architects of Culture list! ADWEEK’s inaugural Architects of Culture award celebrates senior leadership across the marketing, advertising, and technology industries who are actively creating environments where talent can learn, thrive, and make an impact.

Since co-founding Collectively in 2013, alongside Co-Founder and CEO Ryan Stern, Alexa has built what many call the “anti-agency agency,” a place where high-performers show up authentically, love their work, and grow into creative leaders. Her philosophy is simple: When people feel seen and heard, they create the best work of their careers.

Alexa stands by the belief there’s no “I” in culture, only the collective(ly) “we.” That truth comes alive through what we call The Collectively Code, five guiding principles that go beyond words on a wall: we’re in this together, do the right thing, make it amazing, step up, and stay curious. The Code is a living blueprint shaping how teams collaborate, how we overdeliver for clients, and how creators are valued.

In 2025, Collectively grew its talent by 20% and promoted a quarter of the agency. Through initiatives advocated by Alexa and her teams such as the peer-nominated Step Up Awards, our Diversity Council, seven employee resource groups, and a six-month mentorship program for emerging leaders, Alexa turns belonging into the agency’s greatest strength.
