  • Orkes

    Participated · Series B · Apr 2026

    Orkes builds and operates Conductor, a platform and runtime designed to orchestrate durable, long-running, non-deterministic workflows that include branching, retries, tool calls, and human-in-the-loop steps. The company says Conductor has been widely adopted by enterprises for mission-critical workflows and for building AI agents. Orkes recently open-sourced Agentspan to foster community-driven development of agentic applications and runtimes. The Series B provides $60M in growth capital to double down on the platform and support accelerated adoption as application and agent building accelerates. The announcement frames the company as positioned at an inflection point for software where durable execution, state, and observability are becoming critical. No revenue, user, valuation, or founding-year details were disclosed in the announcement.

  • Cleric

    Led · Seed · Dec 2025

    Cleric offers an AI SRE agent that continuously learns from every incident, alert, and human decision to triage, diagnose, and resolve production issues. The agent integrates with existing observability, CI/CD, and incident-management tools such as Datadog and Grafana, delivering findings in Slack and a web interface with confidence scores and detailed diagnostics. Engineers can guide its reasoning conversationally, and its signal-to-noise ratio improves over time as it learns from feedback. Early adopters, including BlaBlaCar, report recovering 20–30 % of engineering capacity previously spent on repetitive troubleshooting and using Cleric’s insights to drive long-term reliability improvements. Founded by former Gojek platform engineers, Cleric positions itself as building “AI teammates for production engineering.” The company has been recognized as a Gartner Cool Vendor in AI for SRE and Observability 2025. Cleric plans to use newly raised capital to expand R&D in San Francisco, ramp customer deployments, scale production support, and deepen partnerships with observability and infrastructure platforms.

  • SWARM Biotactics

    Participated · Seed · Jun 2025

    SWARM Biotactics builds bio-robotic swarms consisting of living insects—cockroaches—equipped with proprietary sensor backpacks, neural interfaces, and secure communications to enable precise navigation and real-time data collection in cluttered, denied, and high-risk terrain. Its platform combines biology with edge AI, swarm intelligence, and secure communications to provide silent ISR and real-time data for defense, national security, disaster response, and industrial inspection. Founded in 2024, the company is headquartered in Kassel, Germany, with a U.S. subsidiary in San Francisco. SWARM has raised a total of €13 million to date, including a €3 million pre-seed and €10 million in seed funding. The new funding will be used to transition from deep tech R&D to field deployment, including launching operational pilots in Europe and North America, scaling production of sensor backpacks and swarm infrastructure, and expanding R&D and engineering hubs. The company plans to recruit talent in insect neurobiology, embedded AI, field robotics, and dual-use system integration.

  • Recce

    Participated · Seed · Apr 2025

    Recce brings data validation best practices natively into code review to help data-driven organizations ensure the stability and accuracy of critical data transformation projects and complex AI systems. Led by CEO and founder CL Kao, the product originated as an open-source project and now also offers a cloud platform for cross-team collaboration. The platform embeds data validation into the software lifecycle to surface issues during code review. Recce plans to use newly raised funds to expand operations and accelerate development efforts. Its open-source project sees about 3,600 downloads per week on GitHub, with users including The Philadelphia Inquirer, telecom companies, healthcare tech startups and government entities in Brazil and Australia.

  • Olix

    Participated · Seed · Apr 2025

    Founded in London by James Dacombe in 2024, Olix develops the X-1 platform that distributes AI model workloads across specialised chips connected by an optical interconnect. Its first chip, the DX-1, is a decode accelerator that the company claims can deliver over 10,000 tokens per second per user on 100-billion-parameter models while using less power for large batches, and is designed to scale to models with trillions of parameters. Olix has over 140 employees across London, Bristol, Toronto, Austin and San Francisco. The company plans to launch DX-1 to initial customers in the second half of 2027 and to ramp platform development and chip manufacturing with the new funding. Olix has rapidly increased its valuation through multiple funding rounds, most recently reaching $3.3 billion after the $312 million raise, up from just over $1 billion in February. The AI chip market in which Olix competes was valued at about $84 billion in 2026 and is expected to grow rapidly through 2030.
