- BoolSi
Participated · Seed · Jun 2026
BoolSi offers a compilation platform that automatically synthesizes software functions into custom digital logic, producing dedicated coprocessors (hardware agents) as standard compilation output. Its tooling is designed to let users compile software onto silicon by generating custom hardware accelerators from ordinary code. The platform aims to overcome traditional chip design hurdles by delivering generated hardware as part of the compilation flow. BoolSi is headquartered in Boston, MA. Following its seed raise, the company plans to expand operations and accelerate product development using the new funds. The articles do not disclose revenue, user metrics, or other financial performance details.
- Mesoware
Led · Seed · Jun 2026
Mesoware develops an AI-powered ecosystem of modular hardware and software that enables manufacturers to capture tasks for robots and set up productive work cells quickly with minimal robot training. Its platform and modules handle real-world variation—such as differences in part placement, tolerances, and sequence changes—so automated work remains consistent without frequent reprogramming. The company offers native modules and integrations with third-party modules to support tasks including assembly, packaging, and machine tending. Mesoware is initially focusing on automating subassembly processes for products such as drones. Led by CEO Joe Mattekatt and based in Palo Alto, CA, the company recently raised $1.5M in Pre-Seed funding to expand operations and further development.
- Vivere Oncotherapies
Participated · Equity · Jan 2026
Vivere Oncotherapies engineers cancer therapies that activate the immune system to detect and eliminate solid tumors that typically evade immune surveillance. Using a proprietary bioengineering platform created at UC Berkeley, the team designs delivery vehicles that reach tumors more efficiently and release highly selective, immune-stimulating payloads. The company’s scientific approach merges engineering, immunology, and translational expertise to crack the longstanding problem of immunologically cold tumors, which are resistant to conventional checkpoint inhibitors. With its technology, Vivere aims to bring a new generation of targeted and safer immunotherapies to patients who currently have few effective options and poor prognoses. Future plans include advancing these candidates toward clinical development and expanding the platform to additional hard-to-treat cancers. Financially, the company has secured over $10 million in new capital to fuel preclinical development and platform expansion; no other operating metrics or revenue figures were disclosed.
- Edison Scientific
Participated · Seed · Dec 2025
Edison Scientific is developing a full-stack AI research platform aimed at accelerating scientific discovery. At the center of the platform is Kosmos, an AI scientist capable of executing hundreds of research tasks in parallel, including literature synthesis, data analysis, and molecular design. The company also maintains PaperQA, an open-source literature agent that it is preparing for a major release as part of its open-science commitment. Led by CEO Sam Rodriques and CTO Andrew White, Edison Scientific positions its tools to help researchers move rapidly from initial questions to validated breakthroughs. The recent $70 million seed financing provides substantial capital to scale operations and deepen product development. Although the company has not disclosed revenue or user numbers, the sizeable seed round underscores strong investor confidence in its technology and market potential. With fresh funding, Edison Scientific plans to expand both its operational footprint and the capabilities of its AI research stack.
- Addis Energy
Participated · Seed · Dec 2025
Addis Energy is developing a novel geologic ammonia production method that injects nitrogen and water into iron-rich subsurface formations, using natural underground heat and pressure to synthesize ammonia. An AI-aided laboratory of chemical reactors replicates these conditions, allowing the team to test more than 600 rock samples sourced from formations across the United States. By avoiding natural-gas feedstock and the extreme conditions of Haber-Bosch, the process promises a net energy-positive, zero-emission route to ammonia at a significant cost advantage. This innovation targets a market where 70 % of ammonia becomes fertilizer and demand is projected to rise 25 % within five years. The company’s approach could reduce both energy consumption and carbon footprint, providing a domestic alternative in a supply-constrained U.S. market. Cambridge, Massachusetts-based Addis plans to expand its operations team, finish nationwide geological mapping, and move toward its first field pilot. The startup has secured $17.3 million in total funding, including a newly raised $8.3 million seed round.
