Software Engineering Analytics Platform Semmle raises $21m in Series B funding

San Francisco, CA-based Software engineering analytics platform, Semmle has raised $21m in Series B funding. The round was led by Accel Partners, with participation from Work-Bench. As part of the investment, Accel’s Ping Li and Vas Natarajan will join the board of directors.

The current investment which brings Semmle’s total funding to $31 million, will be used to accelerate its go-to-market efforts serving large technology and financial services companies around the world.

Founded by Dr. Oege de Moor, Pavel Avgustinov and Julian Tibble, Semmle provides an analytics platform to create reliable code without slowing down. The company’s analytics platform combines deep semantic code search and data science insights from its community of 500,000 developers to help them better understand their code, engineering processes, and people. It is powered by QL, a query engine that lets developers and security researchers turn their source code into searchable relational data in order to spot critical errors and variants virtually impossible to find any other way.

“The greatest scientific and technological breakthroughs throughout history resulted from combining different disciplines, such as the use of computer science and biology to sequence the human genome,” said Dr. Oege de Moor, CEO of Semmle. “We built Semmle on this same principle, bringing together our 100+ patents in database technology and programming to enable deep semantic code search. With Semmle, CIOs, developers and security researchers can finally answer previously unanswerable questions about their code to find coding mistakes and 0-days that would otherwise be invisible.”

The platform, which uses AI techniques to present actionable recommendations for improvement to developers and managers, building on the data from the user community, is used by software engineering and security teams at Credit Suisse, Dell, Google, Microsoft, NASA, and Nasdaq.

“The stakes have never been higher for securing the world’s software,” said Accel’s Ping Li. “By making code searchable in a database, Semmle is redefining what’s possible in terms of fidelity of the analysis. It’s why Semmle is already trusted by the most innovative and valuable organizations in the world like Google and Microsoft.”

The company, which also has offices in Copenhagen, New York City, Oxford, Seattle and Valencia, Spain, has a team of more than 60 cross-functional experts includes computer scientists, biochemists, astrophysicists, clinical scientists and mathematicians, more than half of them hold PhDs. The Semmle team spent 10 years researching and creating the solution that is now the QL engine behind Semmle’s LGTM platform; they now hold 82 technology patents, with an additional 25 patents pending.
