Advertising analytics platform Metamarkets raises another $15M

Metamarkets, a San Francisco startup providing streaming analytics to advertisers, has raised a $15 million round of venture capital. Data Collective led the round, which also included John Battelle and City National Bank and existing investors Khosla Ventures, IA Ventures, True Ventures and Village Ventures. Metamarkets (see disclosure) has now raised more than $43 million since launching in 2010.

While the company’s product, like most software as a service, is tied to a rather specific use case, its technology is not. To many engineers working on big data systems, Metamarkets is also known as the creator of Druid, an open source data store the company created in order to handle the speed and scale its analytics platform requires. Last week, Metamarkets announced that Druid is now available under the permissive Apache 2 open source license.

Metamarkets CEO Mike Driscoll has a clear view of where the software world is headed, and he thinks his company is one of many helping take it there. Essentially, it’s a world where applications are delivered as cloud services, and infrastructure technologies become commodities, often created and then open sourced by the companies building those applications.

If you look at the technology landscape today, it’s hard to argue with that premise. Large companies such as Google, Facebook and Yahoo have created a large number of today’s popular data analysis, data storage, programming and other technologies, and now Metamarkets, Airbnb, Twitter and others are getting in on the act. It’s not wholly inconceivable that future developers, even at the enterprise level will be able to find anything they need as open source, meaning money only has to change hands for services, support and, of course, applications.

The Druid real-time database moves to an Apache license

Druid, an open source database designed for real-time analysis, is moving to the Apache 2 software license in order to hopefully spur more use of and innovation around the project. It was open sourced in late 2012 under the GPL license, which is generally considered more restrictive than the Apache license in terms of how software can be reused.

Druid was created by advertising analytics startup Metamarkets (see disclosure) and is used by numerous large web companies, including eBay, Netflix, PayPal, Time Warner Cable and Yahoo. Because of the nature Metamarkets’ business, Druid requires data to include a timestamp and is probably best described as a time-series database. It’s designed to ingest terabytes of data per hour and is often used for things such as analyzing user or network activity over time.

Mike Driscoll, Metamarkets’ co-founder and CEO, is confident now is the time for open source tools to really catch on — even more so than they already have in the form of Hadoop and various NoSQL data stores — because of the ubiquity of software as a service and the emergence of new resource managers such as Apache Mesos. In the former case, open source technologies underpin multiuser applications that require a high degree of scale and flexibility on the infrastructure level, while in the latter case databases like Druid are just delivered as a service internally from a company’s pool of resources.

However it happens, Driscoll said, “I don’t think proprietary databases have long for this world.”

Metamarkets open sources Druid, its in-memory database

Metamarkets is open sourcing its in-memory database technology called Druid. The rationale for open sourcing a key piece of its technology platform is both altruistic (better all!) and a savvy recognition that if the startup doesn’t do it, someone else will build it.

Why you (yes you) should donate your medical data
