  • Fleet Device Management

    Participated · Series B · Jun 2025

    Fleet builds an open-source device management platform that gives IT and security teams visibility, control, and automation across macOS, Linux, and Windows. The platform supports both self-hosted and Fleet-hosted (cloud) deployments to meet strict data-privacy and regulatory needs. Fleet says it enrolls millions of devices and is used by customers including Stripe, Fastly, Uber, Reddit, Nutanix, and MrBeast. The company emphasizes transparency, extensibility, and repeatability as differentiators from traditional closed MDM vendors. Fleet’s roadmap is driven by partner and customer feedback and includes continued development of enterprise-grade managed hosting alongside self-hosting capabilities. Leadership highlights in the article include CEO Mike McNeil and a board addition from Ten Eleven Ventures’ Scott Lundgren. Fleet Device Management builds open-source software to manage and secure computing infrastructure, including employee laptops and cloud servers. The platform helps IT, security, and development teams automate, manage, and understand devices in real time. It has seen adoption and contributions from engineers at companies such as Uber, Atlassian, Heroku, Dropbox, Square, Ernst & Young, Wayfair, Yubico, Schrödinger, and Gusto. The company is led by co-founder and CTO Zach Wasserman and CEO Mike McNeil and is based in San Francisco, CA. Fleet intends to use the $5M seed funding to expand operations and broaden its business reach.

  • Mermaid Chart

    Participated · Seed · Mar 2024

    Mermaid builds hosted services around the open-source Mermaid project, a Markdown-like language for creating diagrams and charts. The project was created by founder Knut Sveidqvist and later commercialized after Open Core Ventures connected him with CEO Andrew Firestone. Mermaid's cloud offering had about 4 million users last year. The company is adding features to broaden adoption beyond technical users, including an opt-in visual editor and a trained AI model to generate and fix diagrams via chat, with AI fixes available to paying users. Its longer-term vision is to enable process and workflow automation and pursue use cases adjacent to tools like ServiceNow rather than directly displacing Lucidchart or Miro. For now the team is focused on building out the service and reaching a broader audience so Mermaid can become a vital knowledge base for companies that adopt it.

  • FlowFuse

    Participated · Seed · Nov 2022

    FlowForge is an open-source PaaS for IoT that enables engineers, systems integrators, and control engineers to bring Node-RED into production. The platform adds enterprise capabilities such as multi-tenancy, role-based access control, and customer support. Together with Node-RED, FlowForge positions users to build applications in the physical world rather than just web applications. The company was founded by Nick O’Leary and Zeger-Jan van de Weg and is based in San Francisco, CA. FlowForge raised a seed round and intends to use the proceeds to accelerate growth, expand operations, and broaden its business reach. No operating metrics or prior rounds were disclosed in the article.
