Overlay Capital Research
Investment Thesis
Overlay Capital is a private investment firm founded in 2022 in Alpharetta, Georgia, built around a single thesis: identify structural shifts in essential infrastructure systems early, before markets fully price the risk and opportunity. The firm's stated mission is to invest in "the essential systems that will power, connect, and sustain modern life over the next 50 years." Unlike a traditional startup-focused venture fund, Overlay operates as a multi-vertical infrastructure investment platform, combining structured project finance, platform equity, and asset management across three core verticals: Energy Finance, Fusion & Firm Power, and Waste & Materials. Its investment ethos, stated directly on its site, is that it invests "where structural change is inevitable, but not yet priced."
Sector Focus / Stage Focus
Overlay's three verticals are distinct in mechanism:
- Energy Finance: structured credit and bridge facilities for power generation developers, specifically financing grid interconnection deposits — the primary bottleneck constraining new power development in the US.
- Fusion & Firm Power: equity investments in frontier "firm power" platforms (fusion, advanced fission, hybrid systems) and the enabling infrastructure around them (magnets, fuel cycles, materials, thermal systems, grid integration).
- Waste & Materials: equity and platform investment in AI/robotics-enabled materials recovery and recycling infrastructure (sortation, advanced processing, offtake-backed assets).
This is not a conventional pre-seed-to-Series-A venture shop. Energy Finance deals are structured, development-stage infrastructure credit tied to milestones rather than growth equity. Fusion & Firm Power and Waste & Materials investments are typically later-stage platform equity into capital-intensive, technically de-risked companies (e.g., Commonwealth Fusion Systems, Zap Energy, AMP Robotics). Per-company stage/round detail was not independently sourced during this research pass, so stage is not attributed at the portfolio-company level.
Check Size
Limited public deal-size disclosure. One confirmed data point: a $20 million structured bridge facility to Accelergen Energy for grid interconnection deposits. Overlay Asset Management also serves institutional partners (RIAs, family offices, foundations, endowments) via discretionary and sub-advisory mandates, suggesting a broader range of ticket sizes depending on structure. Insufficient evidence to confidently set a firm-wide check size range.
Lead Tendency
Overlay structures and leads its own bespoke credit facilities in Energy Finance (bridge facilities, credit facilities for interconnection deposits) and participates as a direct investor in Fusion & Firm Power and Waste & Materials platform deals. Best characterized as "both" — it originates and structures its own credit deals but also co-invests alongside other capital in equity platforms.
Recent Activity
Overlay has been highly active in 2025–2026, primarily in Energy Finance interconnection-deposit funding:

Per the firm's own 2025 recap, its energy finance platform had financed more than 3 GW of generation assets, and by Dec 2025 the firm reported surpassing 4 GW in Energy Finance deployments. Fund status: actively deploying across all three verticals, with two flagship vehicles (OCIP2, OC WAM Fund I) launched in 2026 and four additional hires planned for the year.

Fusion & Firm Power: Zap Energy, Commonwealth Fusion Systems, Pacific Fusion, Avalanche Energy, Xcimer Energy, Type One Energy, Crusoe. Waste & Materials: AMP Robotics, Sortera Technologies, Molg. Energy Finance borrowers/partners: Accelergen Energy, Belltown Power, Grid Connected Infrastructure (GCI). No disclosed exits or acquisitions to date.
Team
- Chadd Evans, CFA, CAIA — Managing Partner & Chief Investment Officer. Leads the firm's primary investment business across all three verticals; previously a founding partner at Altera Investments.
- Eric Rubinstein — Managing Partner, leads Energy Finance. Joined October 2025; veteran energy infrastructure investor with experience as both a developer and underwriter.
- Brett Wayman — Managing Partner & COO; also leads Overlay Asset Management. Opened the firm's Denver office in 2024.
Decision Process
Overlay Asset Management's own materials describe "formal underwriting and investment committee processes," indicating an investment-committee-driven decision process rather than a solo-GP model, consistent with a multi-partner structure (Evans, Rubinstein, Wayman) with defined risk-management and mandate-governance frameworks.
Founder / Counterparty Preferences
Overlay does not back early-stage startup founders in the traditional VC sense. Its counterparties are (a) power-project developers needing structured capital at the interconnection-deposit stage, and (b) technical teams building capital-intensive frontier infrastructure platforms (fusion reactor developers, AI-driven materials recovery operators) with credible paths to commercial deployment at scale.
Geographic Focus
Headquartered in Alpharetta, GA (Atlanta metro), with a second office in Denver, CO. Deal activity spans multiple US ISOs/RTOs (WECC, SPP, PJM referenced) and states; Overlay Capital Canada, Ltd. exists as a subsidiary of the parent Overlay Group, LLC, suggesting some Canadian exposure. Geographic focus is effectively North America.
