  • Rendezvous Robotics

    Participated · Seed · Sep 2025

    Rendezvous Robotics is developing reconfigurable space infrastructure based on modular "tesserae" tiles that magnetically latch and self-reconfigure in orbit. The flat-packed tiles launch in dense stacks, are roughly the size of a dinner plate and an inch thick, and each contains a processor, sensors and a battery intended for low-cost mass manufacturing. The company uses autonomous swarm assembly and electromagnetism so tiles can find each other, dock, unlatch and rearrange via software commands. The technology was invented by Ariel Ekblaw during her time at MIT, incubated at the Aurelia Institute, and the company was formalized around Thanksgiving 2024; it is headquartered just outside Denver. Tile prototypes have flown on Blue Origin's New Shepard and on two missions aboard the International Space Station, which demonstrated autonomous docking, self-correction and reconfiguration. Rendezvous plans an ISS demo in early 2026, an external ISS mission in late 2026 or early 2027, and a subsequent mission to build a functional antenna aperture; it closed a $3M pre-seed to hire and advance the tech from demo to a full-scale orbital product.

  • MacroFab

    Participated · Equity · Jan 2023

    MacroFab offers a technology platform that advances electronics manufacturing by streamlining operations, improving efficiency and providing visibility into production. The platform supports prototypes, production, and extended services through a network of over 100 factories across North America. The company intends to use newly raised capital to further advance its platform, expand operations and accelerate revenue growth. MacroFab recently received $20M in growth financing from Trinity Capital Inc. (NASDAQ: TRIN). Earlier this year it raised $42M in equity led by Foundry and joined by BMW i Ventures, Edison Partners and ATX Venture Partners. Those rounds bring the company’s total capital raised to $102M. MacroFab is a Houston, TX–based cloud manufacturing platform that manages electronics manufacturing from prototype to high-scale production. Its technology platform connects customers to a network of 100+ factories across North America and provides visibility into production. Led by CEO Misha Govshteyn, the company reported shipments were up 275% year-over-year as companies moved electronics production to North America. MacroFab has doubled its workforce and opened a new facility in Mexico. The company raised $42M in new growth funding and has now raised a total of $82M. It intends to use the funds to continue expanding operations and broaden its business reach. MacroFab provides a digital platform that enables supply chain teams to build everything from PCB assemblies to fully tested and packaged electronics products. Enterprises use the system to consolidate vendors or reshore production from China to North America. The company aggregates unused capacity at 75+ factories across the US, Canada and Mexico to offer mid-market firms an alternative to offshoring amid constrained capacity and disrupted lead times. MacroFab is led by Misha Govshteyn (CEO), Chris Church (Founder and Chief Product Officer) and Chris Granberry (COO). The company plans to use the new funding to accelerate expansion in North America, increase investment in R&D and sales/marketing, and open a new distribution center for international logistics this summer. MacroFab raised $15M in a Series B round announced May 26, 2021. MacroFab provides a cloud-based platform where users can upload PCB designs, get instant quotes, and have boards printed in MacroFab’s factory. The platform includes access to an inventory of over 250,000 electronic components and a pricing/risk matrix that suggests parts based on production scale. MacroFab’s software consolidates multiple prototyping orders into larger jobs so setup costs can be shared, enabling lower-cost one-off prototype runs. About half of the company’s orders are small-quantity test boards and the other half are larger mass-production orders. The company also offers a full-service API allowing programmatic quoting and ordering without visiting the site. MacroFab plans to use new funding to bolster its R&D staff and add new platform features.
