Blackwall Secures $100 Million Funding Round Valued at $2.2 Billion

Estonia-based company Blackwall has announced a significant funding round, raising $100 million at a valuation of $2.2 billion. The Series C investment was led by AVP and saw participation from existing investors including Dawn Capital, MMC Ventures, and Tera Ventures.

This latest funding round marks a substantial increase in Blackwall's valuation, quadrupling since its previous fundraise in 2025 according to Roi Carthy, the company's executive chairman. The significant growth in valuation reflects the growing importance of web traffic security tools in today's online landscape.

As the internet becomes increasingly crowded with bot traffic, especially AI agents, websites are struggling to keep up. Web infrastructure companies like Cloudflare and Akamai are facing a surge in demand for their services as they deal with DDoS attacks, scraping, botnet farms, and malicious requests.

Blackwall is capitalizing on this trend by providing web hosting providers and websites with the tools they need to manage unwanted traffic. However, unlike some of its competitors, Blackwall is taking a unique approach to sales by working through channels rather than directly selling to end-users.

Blackwall's business model is designed to be flexible, allowing hosting companies to customize their security solutions based on their specific needs. This is made possible by the company's modular approach, which enables customers to mix and match various security components.

The arrangement benefits both parties, as hosting companies can set their own prices for these services and share revenue with Blackwall. The company initially provides a free tier that offers basic traffic monitoring and threat detection capabilities.

To differentiate between legitimate visitors and malicious bots, Blackwall employs advanced techniques such as digital fingerprinting to identify the software behind each request. This allows the company to filter out unwanted traffic and provide more accurate threat intelligence to its customers.

As AI agents become increasingly prevalent in online interactions, Blackwall is positioning itself to capitalize on this trend. The company's systems will need to adapt to manage the access and authorization of these digital entities, ensuring they can interact with websites safely and securely.

Blackwall is not alone in recognizing the potential of AI-powered internet management. Cloudflare's AI Crawl Control allows website owners to selectively permit or block individual AI crawlers and even charge them for access.

However, Blackwall's advantage lies in its ability to enable hosting providers to offer traffic management services directly to their customers, rather than handing over the customer relationship to another security provider.

The company plans to use the recent influx of funding to expand its operations into new regions, including North America, Europe, Asia-Pacific, and the Middle East. This expansion will be accompanied by the development of additional security tooling for hosting, cloud, and managed service providers.

Blackwall's growth is part of a broader trend as companies seek to manage the increasingly crowded internet landscape. By providing hosting providers with direct access to traffic management services, Blackwall aims to help them stay ahead in this evolving market.

Blackwall's recent valuation surge to $2.2 billion is a testament to its success in addressing the growing complexity of internet traffic management.

The company's innovative approach has caught the attention of hosting providers, who are increasingly looking for ways to stay ahead in this evolving market by leveraging Blackwall's direct access to traffic management services.
