In their early years Ben Bromhead and Adam Zegelin wanted to build a marketplace for sharing data sets on the Internet, but they had to work hard and build tools to manage the databases that held all the precious data.

They even cooked up a user interface to see how everything was working in the database, which derived from an open-source NoSQL database known as Apache Cassandra. It all ran on the popular Amazon Web Services public cloud.

“It kind of got to a point where we thought, ‘Maybe somebody else would be interested in this,'” Bromhead said.

Work on the system led to the creation in February 2013 of a startup called Instaclustr to sell the software, which falls under the database-as-a-service category. That year the team met with Nick McNaughton the CEO of a local Venture firm. He was impressed by the scalability of the business and helped the team pull together a US$2M Seed Investment. This included a material investment from the Canberra Business Development Fund managed by Steve Hardy & Michele Troni. This allowed the team to launch the company at the Cassandra Summit in San Francisco in September 2014.

The companies progress and funding are not surprising: The Cassandra open-source community has been growing larger and larger with close to three times the number of attendees at the 2015 Cassandra Summit.

The company has grown out of an office in the Australian city of Canberra and recently opened an office in San Mateo, Calif. While 25 people work for Instaclustr now, the headcount is continuing to grow rapidly to meet the demand from their many global clients.
