  • Peripheral Labs

    Participated · Seed · Aug 2026

    Peripheral Labs uses technology from self-driving cars to reconstruct live sports into broadcast-quality photorealistic 3D volumetric video at lower cost than legacy systems. Its system produces immersive replays that can be explored in 3D and aims to make such experiences scalable for live sports productions. The company is working with leagues and stadiums on deployments. Peripheral plans to launch a browser-based consumer-facing replay product later this year that requires no special hardware. Financially, the company has raised a total of $12.5M following the newly announced $8.7M seed round.

  • Inversion Semiconductor

    Led · Seed · Aug 2026

    Inversion Semiconductor is pursuing a lithography approach that uses high-power lasers to heat a gas into plasma, driving electrons in a magnetic structure to emit light with wavelengths closer to X-rays. The company claims its source can generate up to 500 million pulses per second, compared with about 50,000 pulses per second from current tin-droplet EUV systems. It aims to challenge the dominance of incumbent lithography suppliers by producing a more directed, laser-like light source and contends this could enable up to 15x faster chip manufacturing if successful. The team has reduced the size of its laser from the scale of several football fields to roughly 30 meters by 5–10 meters, but says a test lithography machine is still years away. Financially, it has secured $500,000 in pre-seed funding from Y Combinator and Entrepreneur First and $750,000 in government grants with Lawrence Berkeley National Laboratory, and it was awarded the DOE’s "Genesis Mission" prize.

  • EverSettled

    Participated · Seed · Jul 2026

    EverSettled provides a platform combining AI and human specialists to guide executors through estate settlement, including a 24/7 AI assistant named Sage and a personalized interactive checklist. Launched four months before the funding, the company says it has helped thousands of families across the U.S. and is available in all 50 states. The product can locate bank accounts and policies, cancel subscriptions, negotiate debts, organize documents, and allow multiple family members to collaborate. EverSettled charges about $1,499 billed to the estate, positioning its offering between self-serve software and high-end concierge services. Founded by Arum Kempster and Jacob Effenberger, the team built the product after interviewing more than 170 families and estate professionals and observing probate court processes. With the new funding, the company plans to expand hiring and broaden services to handle more complex estates.

  • Juno Bio

    Participated · Seed · Jul 2026

    Juno Bio offers an at-home vaginal microbiome test that screens for bacteria, fungi and some sexually transmitted infections, and provides an analysis of microbes linked to conditions like bacterial vaginosis and yeast infections. Tests are available in 46 states and are priced at $149 for a single test or $99 for a test every three months, with patients able to book a free follow-up call with a company coach to review results and next steps. The company cites data indicating 67.5% of its customers had been incorrectly diagnosed before using the test and only 13% had been successfully treated. Juno Bio is establishing a CLIA-certified sequencing lab in Oakland to bring testing in-house, improve turnaround and support future research and clinical standardization. Founder and chief science officer Leighton Turner and CEO Hana Janebdar have framed the next phase as scaling clinical infrastructure, expanding access to actionable care and advancing understanding of the vaginal microbiome.

  • Rig

    Participated · Seed · Jul 2026

    Rig provides a secure, organized “traffic controller” layer between AI tools and companies' internal databases, enforcing rules, hiding sensitive customer data, and preventing costly AI mistakes. Its platform gives AI systems constraints and oversight so outputs can be trusted when accessing internal data. The company was founded by Toby Mather and Jacob Langr and is based in London. Rig raised a $2.8M pre-seed round from a mix of venture and angel investors. The founders have emphasized keeping the team small and efficient while building amid rapid changes in AI technology.
