What Circeus does
Circeus is an AI-native B2B software holding company that acquires and operates mission-critical enterprise software businesses on a permanent basis, differentiated from traditional PE roll-ups by its hold-forever philosophy and centralized AI infrastructure. Founded in London in 2021 by Luca Cartechini (CEO) and Gian Maria Gramondi (COO), with Robin Hardt as CFO, the company has completed 18 acquisitions over four years and rebranded from Shop Circle to Circeus in June 2026. The portfolio spans e-commerce enablement (Aiden, 506, Releasit, Wholesale Helper built on Shopify), API infrastructure (KrakenD), document automation (Encodian/Flowr on Microsoft Power Platform), and emerging AI-native capabilities. Circeus serves 200,000+ businesses globally through its portfolio products.
The company's core technology consists of two proprietary AI platforms: SCAIL, the AI operating layer that aggregates performance signals across the portfolio to surface patterns and competitive intelligence, and CircleX, the AI engineering layer that embeds AI engineers directly into portfolio companies to ship AI-native features and automation. These platforms are deployed alongside direct partnerships with OpenAI and Anthropic for frontier model access, and deep integrations with Shopify and Microsoft as ecosystem distribution partners. Distribution occurs through Shopify App Store, Microsoft Marketplace, open-source channels, and direct enterprise SaaS sales.
Circeus generates revenue through SaaS subscriptions across its 18 portfolio companies serving 200,000+ businesses, supplemented by value creation through M&A — improving EBITDA, Rule of 40 scores (+1,800 bps average improvement), and operational metrics via AI deployment. The company has raised $220M+ in total capital ($120M+ equity, $100M credit facility from i80 Group) from institutional investors including QED Investors, NFX, 645 Ventures, Endeavor Catalyst, 3VC, Nextalia, CDP Venture Capital, and the European Bank for Reconstruction and Development. Operating geographies span London (headquarters), Milan, and Sarajevo, with end customers in 80+ countries.
