AI Security, Cloud Observability and Digital Health Startups Secure Major Funding

Venture investors announced several substantial funding rounds spanning cloud infrastructure, AI security and digital health. Groundcover raised $100 million, Onyx Security secured $113 million at a reported $640 million valuation, and Throne Science closed a $10 million Series A—highlighting continued appetite for companies addressing urgent enterprise and healthcare problems.

• Groundcover’s $100 million Series C will support North American sales, international expansion and cloud-provider partnerships.
• Onyx Security’s $113 million Series B reflects growing demand for controls around enterprise AI agents.
• Throne Science raised $10 million to advance its AI-powered toilet sensor, clinical validation and consumer education.
• For venture-backed technology companies, funding creates an execution challenge: converting capital into repeatable revenue.

One Peak led Groundcover’s Series C, with participation from Morgan Stanley, Zeev Ventures, Angular Ventures, Heavybit and Jibe. The round reportedly values the cloud observability company at $500 million.

Groundcover uses eBPF, a Linux technology, to collect logs, metrics and traces without requiring application code changes. Its pricing is not tied directly to telemetry volume, allowing customers to monitor lower-priority workloads that usage-based models can leave unobserved. Customers can also retain data in their own cloud environments and manage storage costs by moving older telemetry to less expensive infrastructure.

The company says more than 250 organizations use its platform, including customers with seven-figure contracts. Its new capital will fund go-to-market activity in North America, international growth and joint sales initiatives with cloud providers—areas where disciplined commercial ownership can matter as much as product capability. A fractional CRO can help a scaling SaaS company formalize those motions while owning pipeline and revenue outcomes without the cost of a full-time executive hire.

Israeli cybersecurity startup Onyx Security raised $113 million in a Series B led by Bessemer Venture Partners, only four months after emerging from stealth. The financing follows $40 million in earlier funding and reportedly lifts the company’s valuation to approximately $640 million.

Onyx helps enterprises discover, govern and monitor AI agents. Its platform manages permissions, tracks agent activity and identifies potentially harmful or unintended behavior. The company plans to invest in AI model development and expand sales, business development and marketing operations in the United States and other international markets.

With more than 80 employees and Fortune 500 customers, Onyx is moving quickly from product validation to category creation. Its partnership with Anthropic further underscores enterprise demand for safer AI adoption. The commercial task now is to translate that urgency into a scalable market narrative, repeatable enterprise sales process and efficient expansion—core responsibilities for an accountable revenue leader.

Austin-based Throne Science closed a $10 million Series A led by Will Ventures, bringing total funding to nearly $18 million. Founded in 2023, the company sells an AI-powered camera that clips beneath a toilet seat and analyzes waste to generate insights about gut health, hydration and urinary function.

The system uses computer vision models and personalized coaching. The device costs $399, with a subscription priced at $5.99 per month or $69.99 annually. Throne plans to direct the new funding toward research and development, clinical validation and consumer education.

The round illustrates the breadth of digital health investing, but also the difficulty of creating a new consumer category. Throne must earn trust, demonstrate clinical value and build sustainable acquisition economics—commercial problems that require operating leadership rather than advice alone.

Across these financings, investors are backing technically differentiated products in markets with clear pressure points: cloud costs, AI risk and overlooked health data. Funding accelerates opportunity, but it also raises expectations for measurable growth.

Founders should connect capital plans to specific revenue milestones, ownership and operating cadence. For companies not ready to hire a full-time CRO, a fractional CRO can provide senior-level strategy and execution, with direct accountability for building the pipeline, sales motion and partnerships needed to turn investment into durable growth.
