What happened

Estonia-based Blackwall raised $100 million at a $2.2 billion valuation on Tuesday, a fourfold increase over its 2025 round, according to executive chairman Roi Carthy as quoted by TechCrunch. AVP led the Series C, with Dawn Capital, MMC Ventures and Tera Ventures participating. Blackwall sells web traffic security tools through hosting and cloud providers rather than directly to websites, and says it separates legitimate visitors and AI agents from malicious bots. Tech.eu noted that a valuation of about €1 billion was reported only last month.

What we know

TechCrunchtechcrunch.comTech.eutech.eu
  • Blackwall raised $100 million in a Series C at a $2.2 billion valuation, per TechCrunch and Tech.eu.
  • AVP led the round; existing investors Dawn Capital, MMC Ventures and Tera Ventures took part, per TechCrunch.
  • Executive chairman Roi Carthy told TechCrunch the valuation is four times that of the company's 2025 fundraise.
  • Blackwall uses a channel model: hosting, managed service and cloud providers white-label its tools, set their own prices and share revenue with Blackwall, CEO Nikita Rozenberg told TechCrunch.
  • Blackwall plans to expand in North America, Europe, Asia-Pacific and the Middle East, per TechCrunch.

What we don't know yet

  • Blackwall's revenue, customer count and profitability were not disclosed in the sources, so the valuation multiple cannot be checked.
  • How well its fingerprinting and intent-analysis methods separate legitimate AI agents from malicious bots has not been independently tested; the claims come from the company.
  • Whether the channel model can hold up against Cloudflare, which offers AI Crawl Control directly to website owners, is untested.

Why it matters

Hosting providers and websites are under growing load from scraping, DDoS attacks and AI agent traffic. Investors are now valuing vendors that let hosts resell bot management under their own brand, a model that competes with Cloudflare and Akamai for the customer relationship.
