  • Yuno

    Participated · Series B · Aug 2026

    Yuno provides an AI-native payments and financial services operating system that connects customers through a single API to payins, payouts, fraud prevention, KYC/KYB, and stablecoins at global scale. The platform is agnostic by design and connects to over 1,000 payment methods and 460+ integrations across 190+ countries, with intelligent routing, one-click checkout, and AI-powered fraud detection. Over the past year the company recovered more than $5 billion in otherwise-failed transaction volume, increased authorization rates by about 5%, saved customers over $500 million in processing costs, and added 150 new integrations. Global brands using Yuno include McDonald's, NetEase Games, GoFundMe, inDrive, and Rappi, and Yuno partners with providers such as dLocal and Prosa to white-label its technology. Founded in Colombia in 2022, the company is expanding its product footprint into in-person payments and agentic commerce while scaling its presence in the United States and deepening regional coverage in the Middle East.

  • Onyx Security

    Participated · Series B · Jul 2026

    Onyx Security is developing an agent-native security and governance platform that continuously discovers enterprise AI agents, inspects every step of their reasoning, and intervenes when necessary to block, require human approval, or redirect agent actions. The unified control plane gives security teams visibility, posture management, and runtime protection, while helping governance teams satisfy regulatory requirements and enabling infrastructure teams to optimize cost, accuracy, and latency. Executives can also track AI adoption and performance metrics through the same dashboard. The system is powered by proprietary supervisory agents and in-house AI models purpose-built to understand and manage other agents in real time. Co-founded by cybersecurity veteran Maxim Bar Kogan and former Nvidia AI researcher Gil Elbaz, the company already serves multiple Fortune 500 customers and employs more than 70 people across Israel, the United States, and Canada. Headquartered in New York and Tel Aviv, Onyx plans to use its new capital to expand product and engineering teams, build additional AI models, and scale go-to-market efforts. The business has raised $40 million to date but has not publicly disclosed revenue or user numbers.

  • Tsuga

    Participated · Series A · Jun 2026

    Tsuga builds an observability platform that runs directly in customers' cloud accounts (AWS, Azure, Google Cloud and regional sovereign clouds) so telemetry data stays inside the customer's environment rather than being routed through a vendor. The company offers a single billing rate per gigabyte, claims to provide unsampled, end-to-end traces (including AI agent traces, prompt and token details, confidence scores, and agent call graphs), and assists customers in optimizing setups to reduce data usage. Founded in 2024 by Gabriel-James Safar and Sébastien Deprez (who previously sold Madumbo to Datadog), Tsuga exited stealth and within six months reported several million dollars in revenue and secured enterprise customers such as Le Monde, Camunda, Buk, and Black Forest Labs, with average contract values in the six figures. Tsuga's product targets cost and data-sovereignty challenges in modern AI-heavy workloads by keeping data inside clients' security perimeters. The company plans to use recent funding to expand its business and speed development of its AI agent observability capabilities.

  • Fuse Energy

    Participated · Series B · Dec 2025

    Founded in 2022 by ex-Revolut executives Alan Chang and Charles Orr, Fuse Energy supplies energy to more than 300,000 UK households and is building a 1 GW generation pipeline. The company says it runs the full energy value chain in-house—generation, trading and retail—which it credits with delivering roughly 17% efficiency gains versus legacy providers. Fuse uses proprietary trading algorithms and a digital twin of each customer property to predict demand and optimise supply at the household level. Management reports the business has been EBITDA-positive every month since December 2025 and that ARR grew 32% in Q1 to over €472 billion ($550 million). Fuse is opening a 32,000 sq ft headquarters in Canary Wharf, plans to hire over 380 people in the next 12 months, and intends to expand into Europe and North America while launching a plug-in solar product for homes.
