Blackwall Raises $100M Series C Led by AVP at $2.2B Valuation to Fight AI-Agent Bot Traffic

Estonia-based Blackwall raised a $100M Series C led by AVP with Dawn Capital, MMC Ventures and Tera Ventures, quadrupling its valuation to $2.2B from its March 2025 Series B. The company sells digital fingerprinting and ML models to hosting providers to distinguish humans from the exploding volume of AI-agent bots, running a channel model that splits revenue with hosts rather than selling to sites directly.
