Investor Profile: Powerhouse Ventures — Thesis, Cheque Size & How to Apply

Founders scouting Powerhouse Ventures funding will find a seed specialist with a single, sharply defined mission: decarbonising the world's energy and mobility systems. Based in Oakland, California, the firm backs seed-stage founders building the future power system across energy, infrastructure and AI. It was founded by Emily Kirsch, Founder and CEO of Powerhouse and Managing Partner of the fund, and its second fund, Powerhouse Ventures Fund II, closed at US$70 million in 2022 with backing from industry heavyweights including Credit Suisse, Constellation Energy, Microsoft, Total Energy and Toyota.

Thesis and focus areas

Powerhouse's thesis is that the biggest gains in the energy transition now come from software: the hardware that converts renewable resources into electricity keeps getting cheaper, so the decisive savings lie in the digital technologies that finance, develop and operate those assets. The firm's own framing is "seed-stage and market-ready" — it backs founding teams scaling proven technologies in established markets to accelerate energy abundance. Its investment buckets are finance and deployment, asset management and optimisation, and market access and participation. The fund sits inside a broader innovation firm that connects startups with corporate partners such as Schneider Electric and Enel, hosts the Watt It Takes founder podcast, and runs New Dawn, its annual gathering of clean-energy leaders.

Cheque size and stage

The firm invests at seed stage. A public investor profile lists an investment range of US$150K–US$350K with a US$250K sweet spot, and the firm has made more than 20 investments from its second fund. Its first fund raised US$5.5 million from backers including Total Energy Ventures and Centrica Innovations. Founders should arrive with a product oriented toward established energy or mobility markets — the firm is explicit that it backs technologies scaling in real markets, not science projects years from revenue.

Notable portfolio

The portfolio reads like a who's who of grid and energy software. Featured companies include ThinkLabs (physics-informed AI digital twins for grid operators), Pearl Street Technologies (interconnection modelling, now acquired), Overstory (satellite and AI vegetation-risk monitoring for utilities), Heron Power (solid-state transformers), Tyba (energy-storage project optimisation), Amperon (demand and renewable-generation forecasting), Terabase and Raptor Maps (utility-scale solar development and operations platforms), Presto (EV charging access for drivers and fleets) and Rock Rabbit (energy-incentive programme management). The firm also joined Carbon Collective's US$2.2 million seed round, backing climate-aligned wealth management.

Team

The firm is led by Emily Kirsch, Founder and Managing Partner, who started Powerhouse in Oakland in 2013 with Sungevity co-founder Danny Kennedy and has spent over a decade at the centre of clean-energy venture building. The investing team includes Shaandiin Cedar, a Principal whose work spans the fund's energy and mobility portfolio. Beyond the fund itself, Powerhouse's broader team runs the innovation firm, connecting startups with corporates and investors across the industry.

How to apply for funding

Powerhouse Ventures does not publish an open pitch-application form on its website — founders will not find a submission portal at powerhouse-ventures.co. The only public channels on the site are the contact and newsletter links. Given the firm's deep ecosystem presence — the Watt It Takes podcast, New Dawn events and its corporate-partner network — a warm introduction through its community or portfolio founders is the most credible route in. Founders should lead with a software-first product aimed at scaling clean energy in established markets, which is the firm's stated sweet spot.
