Prior to joining TenantBase, Underhill spent five years as the CEO of Cresa, the world’s largest commercial real estate firm focused solely on advising tenants, where he led its growth into additional markets worldwide. His previous commercial real estate roles include Americas CEO at Cushman & Wakefield and a regional founder of The Staubach Company, one of the original leaders in tenant rep service innovation.

“How companies use technology to acquire commercial space is ripe for transformation and TenantBase has clearly emerged as the leader, with a proven track record of closing transactions in markets all across the U.S.,” said Underhill. “I’m excited to be joining TenantBase’s strong leadership team. Together, we share a big ambition for creating a company that’s not only a transformative industry leader, but also highly respected for its commitment to innovation, talent and entrepreneurial culture.”

In TenantBase’s short operating history, more than 170,000 tenants have accessed the platform’s on-demand service delivery model, designed to revolutionize the search and lease negotiation process for companies seeking commercial space.

“TenantBase addresses the technology and client-focused solution gap in the market with a tenant-first, tech-enabled offering that provides the user experience expected by tenants today,” Underhill said. “Tenants paying rent are at the very top of the value chain in CRE - they drive the value of buildings, the land, the mortgages, and the leasing transaction marketplace. It’s appropriate that there is a marketplace built for them - and that’s what TenantBase has done.”

“Jim is an accomplished leader in the tenant rep industry and is highly respected for his ability to see the next great opportunity that will push commercial real estate transactions into the digital age,” said Bennett Washabaugh, CEO of TenantBase. “His experience and proven leadership style will help us in this period of rapid scale for our business as tenants are demanding a tech-enabled solution for the commercial real estate leasing process. Together we look forward to partnering with the industry to revolutionize how transactions are initiated and executed online.”

Frequently Asked Questions

How does TenantBase's technology-enabled platform simplify the process of finding office space for businesses?

TenantBase simplifies the office search by reversing the traditional commercial real estate model. Instead of businesses spending weeks searching listings and contacting landlords, tenants begin by sharing their space requirements, including location, size, budget, and timing. TenantBase’s technology then matches those needs with qualified local tenant-representation brokers and relevant market options.

What role do local tenant representation brokers play in TenantBase's commercial real estate leasing process?

Local tenant-representation brokers provide market expertise, advocate for tenant interests, and manage the leasing process from start to finish—space selection, negotiations, and concessions—helping reduce risk and improve outcomes.

How can I use TenantBase's blog to compare different commercial real estate leasing options?

The blog breaks down lease structures (Gross, Net, Modified Gross) and explains how costs like taxes, insurance, and CAM charges affect total occupancy expenses so readers can compare trade-offs.

What insights does the Partner Broker Highlight section provide for businesses searching for office space for rent?

Partner Broker Highlights showcase trusted tenant-rep brokers, their experience, and advice—building transparency and trust while sharing negotiation and market insights.
