Zeeba, an on-demand van rental service, announced plans to grow its fleet by an additional 4,000 vans by the end of 2021, expanding its business exponentially from the West coast to a nationwide presence.

Currently the startup’s vans are available to book, unlock, and drive throughout Los Angeles, San Diego, Sacramento, and Seattle, all from the Zeeba app or mobile site.

“Our business model is much more fluid and requires less commitments in terms of renting large facilities with long-term leases, or having a heavy operational team in the field,” CEO Kayvon Marashi said in a statement. “We can expand on a much bigger scale, and enter new markets rapidly. So the next van you see out on the road may very well be a Zeeba van."
