Threat Stack Raises $45M in Series C Funding to Accelerate Cybersecurity Innovation & Market Expansion

This is another landmark day in Threat Stack’s growth: It’s with great excitement that we announce that Threat Stack has secured $45 million in a Series C funding round led by F-Prime Capital Partners (the venture capital group associated with the parent company of Fidelity Investments), and Eight Roads Ventures, along with participation from existing investors Scale Venture Partners, .406 Ventures, and Accomplice.

Leveraging strong customer adoption and robust organic growth, we have set our sights on expanded opportunities in existing markets as well as entry into new sectors. Further investment in innovation will consolidate Threat Stack’s leadership in the cybersecurity market as we continue to develop the industry’s most comprehensive intrusion detection platform for cloud, hybrid-cloud, and on-premise environments.

How We Got Here

In April 2016, I announced our Series B financing. At that time, we were focused on continued investment and market validation of the Threat Stack intrusion detection platform and executing on a well-defined go-to-market strategy. Since then, we have learned a great deal from our customers, our employees, and the market at large. These stakeholders have enabled us to make critical pivots that continue to strengthen the company, our platform, and our ability to execute on our growth strategy.

I’m proud to say that we have achieved outstanding results. Eighteen months after our Series B funding, we have experienced 358% Revenue Growth, 259% Customer Growth, and 175% Employee Growth. With figures like these, I can honestly say I’m thrilled with our team’s performance, and it is an honor to be leading such a dedicated group of professionals.

The Future Ahead

Our strong business performance across multiple key metrics provided us with a number of funding options as we looked to accelerate our business growth and innovation. We have positioned ourselves as the provider of the industry’s most comprehensive intrusion detection platform for cloud, hybrid-cloud, and on-premise environments. And our success has been driven by the creation of a company culture centered on “conviction for the mission”, which is fueled by our talented team, attention to customers, and a passion for cybersecurity innovation and business growth.

Simply stated, our mission is to drive “Security at Speed and Scale” for companies of all sizes, from small, rapidly scaling startups to massive corporations with complex legacy infrastructure. We recognize that companies need to capitalize on the business benefits of cloud infrastructure and automation in order to compete. Threat Stack is committed to helping them do that securely.

In addition to accelerating innovation, we have our sights set on extending our reach in North America and around the globe — to help more companies achieve security at scale. Leveraging Boston’s world-class cybersecurity and DevOps talent pool, we have an opportunity to make history by building the next great Boston-based cybersecurity company. Threat Stack’s value is at the intersection of cloud-computing and cybersecurity — two of the most vital and rapidly evolving areas in technology today. We believe our continued focus will help us become a disruptive leader in a market that promises unbounded growth.

Wrapping Up . . .

In closing, I would like to express my sincere thanks to two major additions to our investment team: F-Prime Capital Partners and Eight Roads Ventures. Their collective experience and success, domestically and globally, will be a valuable asset as Threat Stack drives to its next level of success. And, of course, I would also like to express my gratitude to the ongoing participation of our existing investors: Scale Venture Partners, .406 Ventures, and Accomplice.

As well, my deep thanks goes out to the Threat Stack team — whose hard work and passion have brought us this far and will carry us forward to new successes.

Finally, I’d like to thank all of you — the customers who trust us to help you scale your businesses and who continually offer great feedback and support. We look forward to working with all of you well into the future.
