Octostar, an Ireland-based investigative and decision intelligence platform, has raised €6.1M ($7M) in a Seed round extension. The platform fuses petabyte-scale structured and unstructured data with AI-assisted analysis for law enforcement, national security, and financial compliance. The capital supports expansion into UK and US markets, product development, and scaling deployments.
Sovereign Platforms Fill Palantir Void
Europe's push for data sovereignty accelerates as nations terminate US vendor contracts. Switzerland ended its Palantir deal over national security risks in February 2026. French firm ChapsVision raised €90M in 2023 for AI data platforms targeting defense and finance. Octostar's EU-native, air-gapped solution positions it as a Palantir alternative amid these shifts.
Geopolitical Risks Drive Sovereignty Shift
Rising cyber threats and EU digital sovereignty mandates expose vulnerabilities in foreign platforms. EU Parliament voted 471-68 to reduce non-EU tech dependency in security tools. Traditional US-centric tools face scrutiny, with Germany blocking contracts and France dropping vendors. Law enforcement requires secure, on-premise AI to handle OSINT, SIGINT, and cyber intelligence without jurisdictional risks.
Petabyte Fusion Powers Investigations
Octostar integrates data across sources into virtual knowledge graphs, enabling collaborative AI workflows. Domain-specific apps handle SIGINT event analysis, media recognition, and vetting. Unlike Palantir's cloud-heavy model, Octostar's Kubernetes-deployable platform runs fully offline via the Octostar Appliance. Generative AI copilots deliver 2x-100x speedups on tasks without replacing investigators.
As CEO Giovanni Tummarello noted:
"Nations are re-evaluating their technology supply chains…"
Investors Back EU Independence Play
The round includes new backers The Techshop SGR and national institutions alongside Cysero VC. These mission-aligned investors signal conviction in sovereign AI for defense. The funding validates Octostar's traction with EU law enforcement deployments and conference demos at Milipol Paris.
Decision Intelligence Market Expands
The decision intelligence market stands at $20.73B with a 19.1% CAGR. Law enforcement software hits $20.41B in 2026, growing to $40.76B by 2033 at 10.4% CAGR. Competitors like Siren, which raised $10M Series A, focus on link analysis but lack Octostar's full AI decision stack.
Ex-Siren Founders Drive Expertise
Founder CEO Giovanni Tummarello built Siren.io, bootstrapping it to $1M ARR in year one before raising $10M+ as a Gartner Cool Vendor. Cofounder Simone Scarduzio scaled ReadonlyREST Security to $1.3M revenue with a three-person team. Their semantic web and Elasticsearch expertise directly transfers to Octostar's petabyte-scale fusion.
BAE Partnership Fuels Global Scale
Octostar launched a UK subsidiary led by Lee Hannaford and announced a collaboration with BAE Systems for defense AI. Recent C-level hires include CTO Fabio Corneti and COO Zarko Panic. With three EU deployments in Q1 2026 and more planned, the firm eyes rapid enterprise adoption.
