Green 100

What Green 100 does

Green100 (legal name GREEN100) is a private green energy investment firm founded in 2020 by Tomas Simanauskas, operating as a venture capital and investment platform that deploys capital into innovative greentech startups. The firm targets companies across renewable energy, energy storage, hydrogen technology, robotics, sustainable construction, and EV charging, and currently holds six named portfolio companies: Saules Graza (Lithuanian solar PV installations, 150+ MW built), Stuart (EV charging and energy management software), HDRGEN (green hydrogen and eFuels project development), Strato-create (cloud-based AI automation for construction planning), Tiltsun (robotic solar PV installation systems), and Charge-in (EV charging network installation services).

The firm does not develop proprietary technology itself; instead, its intellectual contribution is the investment thesis and portfolio construction around a "100% Green Future" mandate, with a stated 2035 goal of saving 100 million tons of CO2. Reported impact metrics include 204K+ tons of carbon emissions reduced, 120+ green jobs created, and 150+ MW of solar installation capacity supported across portfolio companies.

Green100's business model is return-driven equity investing in early-stage greentech companies, with revenue (for the firm) implicitly tied to portfolio company growth, exits, and value appreciation rather than disclosed management fees or product pricing. Go-to-market is relationship-based enterprise outreach, using website CTAs ("Partner With Us" and "Apply for Investment") to source both startup deal flow and capital from impact-oriented investors. The firm is extremely small (1-10 employees), provides no disclosed financial data, and operates without a public record of fund closings, AUM, or LP composition, which materially limits visibility into its commercial scale despite the portfolio breadth.
