Pulse 2.0: Blackwall Raises $100 Million Series C at $2.2 Billion Valuation

According to Pulse 2.0, Blackwall has announced a $100 million Series C funding round at a $2.2 billion valuation.

Blackwall builds traffic security tools for hosting providers. The Estonia-based company develops products that help websites manage rising volumes of bot traffic, including AI agents. It focuses on DDoS attacks, scraping, botnets, and malicious requests through a channel model that sells to hosting, managed service, and cloud providers.

The round was led by AVP with support from prior backers. Existing investors Dawn Capital, MMC Ventures, and Tera Ventures also participated. Executive chairman Roi Carthy stated the new valuation represents a fourfold increase from the company's previous fundraise in 2025.

Providers customize and resell the tools under their own brands. Customers receive a free tier that displays traffic and threats, then pay for protection features. Revenue is shared between the providers and Blackwall, with providers setting their own pricing for end customers.

Digital fingerprinting and AI models distinguish traffic types. The system identifies software sending requests and analyzes intent and behavior at customer endpoints. Co-founder and CEO Nikita Rozenberg noted this approach separates legitimate visitors and authorized AI agents from disruptive bots.

Blackwall will expand operations and tooling. The funding supports growth across North America, Europe, Asia-Pacific, and the Middle East. The company also plans to develop additional security features for hosting, cloud, and managed service providers.
