Passion. Experience. Vision.


Our Story

FORMATIV principals Sean Campbell and Josh Marinos first met in Jackson Hole, WY, in 2008. Sean was investing in new media companies, after a successful career in trading and finance in New York, and Josh was growing his expertise and leadership in action sports media, events and production. With a shared industry focus, they soon found themselves working together and it quickly became apparent that they not only shared an entrepreneurial spirit, but they approached business with the same spirit: work hard, pursue excellence, be true to yourself, and have fun. 

In 2010 Sean moved to Denver and Josh followed a year later to join the co-founding team behind Battery 621, a shared office space dedicated to the outdoor/active lifestyle industry. With its success, the team was approached by the Mayor and Denver’s Office of Economic Development to expand this vision and  develop a creative office space for technology-focused businesses, emerging companies, and entrepreneurs in Denver.

After looking at sites and opportunities around the metro, the team was drawn to the River North (RiNo) neighborhood and the Mayor’s bold vision for Brighton Blvd, the South Platte River improvements and the new National Western Complex and in 2012, Sean, Josh and team acquired 10-acres at 29th and Brighton Boulevard to develop their new venture: INDUSTRY.  The first INDUSTRY was delivered in 2014 and has become known as a world-class coworking space for technology, digital, and creative businesses, winning the 2017 ULI Impact Award for Innovation.  The space features more than 153,000 SF of shared office, meeting room, and event space, as well as a number of hip restaurants and bars. 

With the success and timing of INDUSTRY, Sean and Josh suddenly found themselves as community and development leaders in Denver’s number one emerging neighborhood, the RiNo Art District. With the spark ignited in Denver’s hot real estate market, and having built a reputation for developing some of the city’s most in innovative, community-centric projects, the two formed FORMATIV in 2016 to build a business centered around the core values that initially drew them together.

Today, FORMATIV focuses on catalytic, mixed-use real estate developments and operates a host of affiliated businesses rooted in people, innovation, and placemaking. The FORMATIV team are active leaders within the Denver’s entrepreneurial and business ecosystem and are passionate about their people, projects and positively impacting community.
