Investment portfolio

  • C-Infinity

    Participated · Equity · Apr 2026

    C-Infinity builds foundational AI for mechanical design and manufacturing through its AutoAssembler platform. AutoAssembler connects to CAD and PLM systems to automate process planning, accelerate engineering change order reviews, and generate production-ready assembly instructions. The technology enables AI to reason about geometry, motion, spatial constraints, and production logic, bringing a new layer of industrial intelligence into engineering workflows. The platform is already in use across Global Fortune 100 manufacturers as well as small and mid-sized enterprises. Early deployments reportedly convert workflows that used to take weeks into processes that take minutes, with implications for faster product launches and lower operational costs. The company is headquartered in Mountain View, Calif., and recently raised $16 million in funding led by Canaan Partners.

  • TensorStax

    Participated · Seed · May 2025

    TensorStax is a San Francisco–based provider of an agentic platform for data engineering that offers autonomous AI agents. Its platform mitigates the operational complexity of data engineering so engineers can focus on modeling business logic, designing scalable architectures, and improving data quality. Early adopters leverage TensorStax for ETL/ELT pipeline building, data lake/warehouse modeling, and pipeline monitoring. The company raised $5M in seed funding to support its growth. The round was led by Glasswing Ventures with participation from Bee Partners and S3 Ventures. Led by CEO Aria Attar, TensorStax intends to use the funds to accelerate product development and consolidate its market position.

  • Sourcetable

    Led · Seed · Mar 2025

    Sourcetable is an AI spreadsheet and data analyst that analyzes Excel and CSV files, creates charts and graphs, cleans data, answers questions, and offers an Autopilot mode for complex spreadsheet work. Its Autopilot can create and edit financial models, generate templates, build pivot tables, clean messy data, format sheets, enrich data, and analyze entire workbooks. The AI understands data context without requiring users to pre-select ranges and can interpret multiple ranges across tabs while seeking human clarification when instructions are unclear. The company was founded by Eoin McMillan and Andrew Grosser and is based in San Francisco, CA. Sourcetable recently raised $4.3M in Seed funding and intends to use the proceeds to expand operations and accelerate development efforts. No operating metrics or valuation were disclosed in the article. Sourcetable is building a new spreadsheet from the ground up that combines familiar cell-based notation with modern data tools. Its product includes charts, graphs, pivots, real-time collaboration, syncing to over 100 business applications, data warehousing, a SQL GUI and editor, publishing features, and standard spreadsheet formulas and shortcuts. Founder Eoin McMillan argues incumbents have stagnated and that owning both the interface and data stack is necessary to make big leaps. The company is operating in private beta and plans to remain in stealth until the end of the year while refining the product with user feedback. Sourcetable plans to add more integrations, templates, analysis, reporting and collaboration features and to build a world-class team. Target customers are professionals who manipulate significant data, such as those in sales, accounting, finance, support and HR.

  • Infactory

    Led · Seed · Oct 2024

    Infactory is a generative AI–based fact-checking startup founded and led by Brooke Hartley Moy (CEO) and Ken Kocienda (CTO), both ex-Humane.AI. The company broke cover in July via a TechCrunch article and emphasizes using generative AI selectively to address online fact-checking. Infactory says it will not use large language models to generate fact-check results; instead LLMs will be used to determine the intent of natural-language search queries. The team prioritizes vetting data vendors over content providers and aims to be selective in partnerships to ensure accuracy. The startup raised a $4M seed at a $25M valuation and plans to use the funding to expand the team and ramp up go-to-market efforts. Kocienda’s 26-year Apple iPhone engineering background is noted as part of the founding team’s credentials. Infactory is building a fact-checking search engine that uses large language models for a natural-language interface while deliberately avoiding generative AI in the results themselves. The service will pull and collate data directly from trusted data vendors and include citations to reduce hallucinations common to generative models. At launch the product will focus exclusively on computational, data-driven queries rather than subjective topics, targeting enterprise subscribers such as newsrooms and research facilities. The company plans subscription pricing aimed at enterprise customers. Infactory is led by CEO Brooke Hartley Moy and CTO Ken Kocienda, both ex-Humane employees, and says a public launch is coming in a matter of months. The founders have raised a pre-seed round (amount and investors not disclosed) and plan to focus on a seed round in the next six to 18 months.

  • Circe

    Participated · Seed · Sep 2024

    Circe uses advanced gas fermentation to convert CO2 into complex molecules, positioning its platform as a carbon-negative alternative to plant- and animal-derived fats and oils. The company has demonstrated prototypes across confectionery, dairy, sugars, protein, polymers, and biofuels and is currently focused on fats and oils due to their broad industrial use. Its pilot plant in Waltham, MA, accelerated by an ARPA-E contract, will move production out of the lab and enable scale-up of carbon-negative molecule manufacturing. Circe reports that its process consumes 3 kg of CO2 for every 1 kg of oil produced, enabling fully carbon-negative outputs. The company is pursuing partnerships to co-develop products across oils, sugars, proteins, and polymers and aims to secure supply chains with drop-in, carbon-negative alternatives. Circe is based in Boston, MA, and is a spin-off of the Wyss Institute at Harvard University, holding a worldwide exclusive license to commercialize the underlying bioproduction technology. Circe commercializes a Wyss Institute fermentation platform that programs microbes to consume greenhouse gases and produce industrial molecules. Its platform has produced triglycerides (used to make fats, butter, oils), sugar‑like molecules, biodegradable plastics, and biofuels using only CO2, water, and electricity as inputs. The company has used its triglycerides to make the world's first gas fermentation‑derived chocolate and is exploring other fats including milkfat and palm oil for food, cosmetics, and fuel applications. Circe emerged from work in Pamela Silver’s lab and was spun out of Harvard after being nurtured at the Wyss Institute; co‑founders include Shannon Nangle and Marika Ziesack. The Wyss Institute designated the platform an Institute Project in 2021 and provided additional funding and validation support to de‑risk the technology. Circe has raised over $8 million from venture investors and previously received $3.2 million from the U.S. Department of Energy’s ARPA‑E ECOSynBio program while still at Wyss.
