- Assail
Led · Seed · Jan 2026
Assail develops Ares, an agentic offensive AI platform that spins up to 100 coordinated AI agents to probe APIs, web, and mobile assets, compressing vulnerability discovery and remediation from weeks to minutes. The system is powered by a proprietary 14-billion-parameter model fine-tuned on offensive tactics and continuously improves by generating its own synthetic training data. Assail has open-sourced an Ares Docker Agent so enterprises can run the technology behind their firewalls, and the full SaaS platform is slated for general availability on February 1, 2026. Since a keynote debut at ISC2 Security Congress 2025, more than 264 organizations have registered for early access, and pilots are under way with Fortune 100 manufacturers, U.S. federal agencies, financial institutions, and leading hospitals. The company was accepted into the NVIDIA Inception program, giving it access to NVIDIA’s startup network. Financially, Assail has raised a $250,000 pre-seed round led by Squared Circle Ventures and secured $100,000 in AWS cloud credits to fund compute-intensive development and deployment.
- Opti
Participated · Seed · Nov 2025
Opti provides security teams with an AI engine that interprets identity risk, recommends least-privilege decisions, and orchestrates continuous access corrections across complex enterprise environments. Its pre-trained, domain-expert LLMs analyze thousands of identity data points in real time, detecting vulnerabilities, misconfigurations, and over-privileged access while delivering validated remediation guidance. The platform is designed for large organizations in finance, retail, healthcare, and technology where continuous compliance and risk reduction are critical. Founded in 2024 by cybersecurity veterans Barak Perelman, Mille Gandelsman, and Ido Trivizki, Opti positions itself as a fully automated replacement for fragmented, manual IAM processes. Customers gain an intelligence layer that makes identity operations faster, clearer, and safer, ultimately lowering costs and elevating security posture. With fresh capital, the company plans to accelerate product expansion and pursue global growth initiatives. No revenue or user metrics were disclosed in the announcement.
