  • MetroElectro

    Led · Debt Financing · Nov 2025

    Founded in 2023 in Melbourne, MetroElectro targets the largely untapped commercial and industrial rooftop segment, where solar penetration is under 5 percent. The startup finances, designs, installs and maintains rooftop solar arrays and battery storage, then sells the generated power to tenants and the grid—often at lower rates than traditional retailers—thereby solving the usual landlord-tenant funding standoff. MetroElectro currently has more than 50 projects in its near-term pipeline, totalling over 20 MW of solar and 20 MWh of storage capacity, enough to power roughly 3,000 homes. Key clients already signed include Aramex, Linde Materials Handling and Bucher Municipal. Management believes raising adoption in the C&I sector to residential-level penetration (about 30 percent) could supply a quarter of Australia’s electricity needs. Proceeds from its newest financing will accelerate deployment of contracted projects and further develop the company’s technology stack to open additional revenue streams. To support longer-term expansion into markets such as Europe and the U.S., MetroElectro plans to pursue an additional $3 million equity raise in early 2026.

  • National Renewable Network

    Led · Series A · Aug 2025

    National Renewable Network (NRN) builds the infrastructure layer that aggregates household rooftop solar and battery systems into centrally managed Virtual Power Plants (VPPs). NRN's platform enables energy retailers to offer white‑label VPP plans with no upfront costs, repayments, or maintenance fees while NRN manages assets independently to avoid retailer asset‑ownership conflicts. The company collects customer energy data to benchmark savings against partner retailer rates and reports that around 80% of customers' energy comes from the behind‑the‑meter solar and battery system. Key technical steps for reliability include installing two 4G modems for redundancy at each site and partnering with quality solar installers for national rollout and maintenance. NRN plans to use recent funding to add 40 megawatt hours of battery storage over the next year and to expand internationally. Financially, NRN completed a $67.2 million Series A (equity and debt) and previously raised $10 million in April last year; investors view the model as a clear pathway to address grid stability challenges. National Renewable Network (NRN) installs residential solar panels and battery storage with an offering that removes upfront costs for homeowners. The company was launched in 2021 by Alan Hunter, cofounder of Splend, who serves as CEO. NRN says its model aligns with the objectives of energy retailers and consumers and aims to provide scalable distributed generation and storage. The startup plans to spend $100 million on renewables generation and storage for 15,000 homes by the end of 2026, and aims to deliver systems to 250,000 homes by 2030 and more than two million homes globally by 2040. NRN operates in Australia and is positioning to scale across the market there. Management is preparing for a larger Series A later this year to extend its rollout. National Renewable Network (NRN) is a Sydney-founded startup (2021) that supplies fully installed solar and battery systems through a B2B platform that removes large upfront costs. The company equips both owned and rented homes and offers four active energy plans, including a partnership with Diamond Energy. NRN aims to provide low-cost solar and battery setups to 250,000 Australian homes by 2030 and plans to spend $100 million to install systems in 15,000 homes over the next three years. Its model routes installations and payments through partner energy retailers so customers avoid complex financing and upfront capital. NRN says average customers save between $750 and $900 annually and that the $10 million facility will enable deployment of more than 600 systems in the coming months. The company projects current customers will save more than $6 million over the next decade as a result of the installations.

  • SPEC Toolbox

    Participated · Equity · May 2024

    SPEC Toolbox is a Melbourne-based construction engineering platform founded in 2023 by structural engineers Adam Jones and Ringo Thomas. Originally launched as CLT Toolbox to serve the cross-laminated timber niche, the company rebranded after discovering similar design bottlenecks across a wider range of modern manufactured materials. Its cloud software automates complex engineering calculations, helping designers more easily specify affordable and sustainable materials in building projects. The product has attracted more than 6,000 user sign-ups and 35 product suppliers and has already expanded its footprint into Europe, the UK, and North America. CEO Adam Jones says the new capital will accelerate the product roadmap, onboard additional suppliers, and deepen technical infrastructure. To date, SPEC has raised multiple rounds, including a $1.5 million Seed round in October 2023 and a $1 million bridge round in 2024, prior to the current pre-Series A fundraise.
