  • Harell Data

    Led · Seed · Aug 2026

    Harell Data develops a secure cloud platform that lets data producers host proprietary experimental datasets while permitting ML teams to run training inside the protected environment. Its commercial model includes a direct compute-revenue sharing mechanism that gives data owners a share of the revenues generated during training runs, plus a ‘compound value’ concept where dataset value increases with repeated model improvements. The company is targeting problems in computational medicine but says the approach applies across domains from materials to imaging. Harell Data launched an early-access program with initial datasets from partners including Adaptive Biotechnologies and organizations in Seattle. The team comprises roughly 11 people distributed between Bellevue and Palo Alto. The $15 million raise is intended to fund the platform rollout, partner integrations, and the operationalization of its data-monetization and compliance features.

  • Prosper Medical

    Led · Seed · Jul 2026

    Prosper Medical operates an AI-enabled concierge primary care platform that aggregates patient health data, maintains continuity across interactions, coordinates care, and augments physician workflows with an AI care layer. Founded by Ryan McQuaid and Dr. James Wantuck (the founders of PlushCare), the company aims to deliver a personalized physician relationship at scale. Prosper is available to patients in all 50 states and is in-network with many major insurance plans. In its first months of operation the company has grown to serve thousands of members. Leadership frames the product as augmenting, not replacing, clinicians—combining Prosper AI, a Care Concierge Team, and doctors who arrive with patient context. The company plans to use recent financing to expand its physician network, further develop its AI platform, and accelerate market expansion.

  • Thira

    Participated · Seed · Jul 2026

    Thira develops a secure, self-learning AI system of execution designed to operate across disparate enterprise systems to automate complex back-office workflows. The company combines self-learning agents, enterprise connectivity, governance and an enterprise knowledge graph to provide visibility and control for enterprise operations. Founders Sunny Gupta and Kurt Shintaffer—co-founders of Apptio—lead the company alongside an early team of enterprise and AI veterans. Thira says ten enterprise organizations are acting as design partners as it prepares for a broader launch this fall. The company aims to expand its engineering team with proceeds from its $21 million seed round and deepen collaboration with those design partners. Thira frames its mission around returning $1 trillion of enterprise spending for reinvestment in innovation by changing how enterprise processes are executed.

  • General Compute

    Led · Seed · May 2026

    General Compute operates an inference-focused neocloud that rents AI processing power for models during the active inference phase. The company has partnered with SambaNova and has $300 million of the vendor’s SN50 inference chips on order to power its offering. Its hardware choice emphasizes air-cooled, lower-power chips that can be colocated in existing data centers and repurposed crypto-mining facilities. General Compute launched its cloud offering recently and claims to be the fastest at running the MiniMax 2.7 open-source LLM. The founders, CEO Finn Puklowski and CTO Jason Goodison, are pursuing colocation deals to scale capacity without heavy infrastructure buildouts. Financially, the company completed a $15 million seed round at a $60 million post-money valuation led by FUSE VC, with participation from Carya Venture Partners, Village Global Ventures, and investment from Evercrest Capital Partners.

  • Portal Space Systems

    Participated · Series A · Apr 2026

    Portal Space Systems is developing solar thermal propulsion engines that concentrate sunlight to heat propellant and enable higher-thrust, high-impulse maneuvers in orbit. Its Hex thruster integrates a combined solar concentrator and nozzle and the company cites advances in additive manufacturing and materials science as enablers. Portal has demonstrated flight electronics on a recent shakedown mission and plans an additional prototype launch in October, with a full engine demonstration on its SuperNova spacecraft targeted for 2027. The company highlights military demand for rapid orbital maneuvering and has received $45 million in strategic U.S. military funding alongside prior private capital. Financially, Portal raised a $50 million Series A at a $250 million valuation in 2024, supplementing earlier private raises. Founded in 2021, the company is led by Jeff Thornburg with co-founders Ian Vorbach and Prashaanth Ravindran.
