Riot's 1,500 Companies Pay for the Employee's Cybersecurity Moment

Benjamin Netter's cybersecurity company, Riot, has a simple proposition. It wants to protect your employees, not just your perimeter. Two years after a $12 million Series A, the Paris-based SaaS firm has closed a $30 million Series B, pushing its post-money valuation above $170 million [TechCrunch, February 2025]. The money follows a revenue jump from $2 million ARR in early 2023 to over $10 million in annual revenue for 2024 [TechCrunch, February 2023][TechCrunch, February 2025].

Riot's traction is measured in people, not just firewalls. It now supports 1,500 organizations, a customer base that includes L'Occitane, Deel, and Intercom [TechCrunch, February 2025]. The platform has interacted with over a million employees, according to the company [TechCrunch, February 2025]. For investors like Left Lane Capital, which led the latest round, the bet is that the human layer of security is the next durable market.

A wedge in the employee experience

Most security awareness training is built for compliance, not adoption. The traditional model involves mandatory, often tedious, annual modules that employees click through to check a box. Riot's approach is to embed security into the daily workflow. The platform provides phishing simulation, two-factor authentication for internal tools, and a cybersecurity hotline, all designed to be low-friction for the end user [Perplexity Sonar Pro Brief, Unknown][tryriot.com, Unknown].

The product syncs with employee directories from Google, Microsoft, Slack, and Okta up to four times a day, automating user management [tryriot.com, Unknown]. The goal is to make the right security behavior the path of least resistance. It is a product philosophy that targets the root cause cited in many breaches: human error.

The founder's pivot from fintech

Netter, who founded Riot at age 30, is not a career security executive [Perplexity Sonar Pro Brief, Unknown]. His background is in building platforms for users. He was previously the CTO of Lendix (later October), a leading SME lending platform in continental Europe [TechCrunch, May 2018]. Before that, he was known in tech circles as a hacker, having built an Instagram-based travel jukebox called 'Somewhere' and serving as a judge for TechCrunch hackathons [TechCrunch, January 2014][TechCrunch, May 2018].

This product-centric, user-experience mindset appears to be the through-line. At Lendix, he built technology for borrowers and lenders. At Riot, he is building for employees. The company now employs 160 people in Paris and plans to double its headcount and open international offices in the next year [Y Combinator, Unknown][techfundingnews.com, Unknown].

Traction and the funding runway

The company's growth metrics tell a clear story of scaling distribution. The jump from 100,000 protected employees in early 2023 to over a million by 2025 indicates rapid customer expansion and upsell within existing accounts [TechCrunch, February 2023][TechCrunch, February 2025]. The $30 million Series B provides a multi-year runway to execute on that expansion, particularly in the competitive US market.

The funding history shows a steady climb in investor conviction.

2023 Series A | 12 | M USD
2025 Series B | 30 | M USD

Early backers included Base10, Y Combinator, and Funders Club, with angels like Snyk founder Guy Podjarny and Supercell co-founder Ilkka Paananen joining the cap table [TechCrunch, February 2023]. The Series B was led by Left Lane Capital, with participation from those existing investors [TechCrunch, February 2025].

Where the wheels could come off

Riot operates in a crowded segment. The security awareness and training market has established giants like KnowBe4, as well as a field of newer entrants like Jericho Security and HEROIC.com. Differentiation on product alone is difficult; the real battle is often fought in sales channels and brand recognition.

The company's model also depends on continuous engagement. If the platform's simulations and tools become just another piece of background noise for employees, its core value proposition erodes. Furthermore, while the 1,500-company count is impressive, the revenue concentration among those customers is not public. A handful of large clients could represent a significant portion of the reported $10 million-plus in annual revenue, creating renewal risk.

Riot's answer appears to be a focus on product-led growth and ease of use, betting that high adoption will drive retention and expansion. The planned international office openings are a direct move to build a sales footprint that can compete with larger, US-based rivals.

The next twelve months

The fresh capital from Left Lane Capital sets a clear agenda. The company will be judged on its ability to convert its European success into meaningful market share in North America. The open role for a Head of US, reporting directly to Netter, is a signal of that priority [Wellfound, Unknown].

Investors have priced in significant growth. The implied valuation of over $170 million, on roughly $10 million in revenue, suggests they are betting on Riot capturing a leading position in the employee security layer. The next milestone to watch is whether the company can double its customer count again, or significantly increase its average revenue per customer, within the next 18 months.

For a company built on the premise that employees are the first line of defense, the question for 2025 is straightforward: can Riot make its own product indispensable enough to defend its newly won valuation?
