Loft Labs raised $4.6 million in seed funding led by Fusion Fund, with participation of RTP Seed, Emergent Ventures, Berkeley SkyDeck Fund, as well as angel investor and Puppet CTO Abby Kearns, who recently joined the company’s advisory board.

Initially, Fusion Fund led a $2.6 million seed round for Loft Labs earlier this year and then offered to expand the round just three months after the initial closing because the investment team at Fusion saw the tremendous commercial traction that the company was able to build up in such a short amount of time. The company’s revenue growth also exceeded the expectations of RTP and Emergent Ventures and together, the three investors expanded the seed round to a total of $4.6 million.

The company’s commercial product, Loft, enables any organization to scale self-service access to Kubernetes to hundreds or even thousands of engineers. Loft’s customers span from fast-growing startups Gusto, Urbint, and HqO to well-established Fortune 500 companies that include one of the largest U.S. financial institutions and one of the world’s largest car manufacturers.

“Our mission is to enable any organization to scale self-service access to Kubernetes from 10 to 10,000 engineers in days rather than years,” said Lukas Gentele, CEO of Loft. “Although Loft is a very new product, we’re already seeing strong demand from enterprises that want to expand their use of Kubernetes and that deploy Loft to become truly cloud-native across all stages of the software development lifecycle. This funding will enable us to accelerate product development and to scale up our customer success team to ensure that we keep on providing enterprise-grade support for our quickly growing customer base.”
