Semilla’s Investment Focus

Semilla Climate Capital is an early-stage venture fund focused on protecting the environment. Semilla’s goal is to provide its Limited Partners with returns that they can then re-invest in additional climate solutions, enabling an ever-increasing amount of capital applied to mitigate climate change.

Our first requirement for an investment is an experienced startup leadership team. They must have first-hand experience in the problem area and have experienced success and failure.

Semilla looks for startups that reduce sales friction as they enter the market. We look for startups that can approach the operator of an industrial facility and show how the operator can both decrease energy consumption and achieve a compelling ROI. We also look for startups that have energy efficiency solutions that can move to adjacent markets, for example, in commercial buildings. Again, the goal of the startup must be to provide an operator with an attractive, near-term ROI.

Given the Semilla General Partners’ long experience in working in and founding hard-tech startups with strong IP, they are comfortable investing in those types of companies. Those companies have long-term sustainable competitive advantages, in contrast to yet another software-only AI startup. Strong IP can also make companies an attractive acquisition target.

The Semilla General Partners have deep experience in investing in Texas and central US startups. The founders of those companies do not over-hype their businesses and have realistic valuation expectations. Similarly, diverse founders also are typically realistic about their businesses and the valuations.

Semilla avoids moon-shot startups that have massive ambitions such as directly scrubbing existing atmospheric carbon or removing plastic waste from oceans. Those companies require investment levels best provided by the government. We avoid trying to identify the winning technology when there are many competitive innovative technologies. And we don’t invest in startups whose revenue growth is dependent upon uncertain and ever-changing government regulations or subsidies.

Semilla is expert at what it does, is well connected with Texas and central US startups, and funds investment opportunities which are often overlooked by east and west coast investors.

Semilla announces an investment in Pure Blue tech

Semilla Climate Capital is pleased to announce an investment in Pure Blue Tech.

Pure Blue Tech offers innovative and patented reverse-osmosis membranes for industrial and utility-scale water filtration that greatly reduces membrane fouling. Reducing and managing fouling is paramount to preventing and minimizing flux loss, energy consumption, and downtime.

Their technology significantly reduces operating costs for water purification operators, and makes increasingly scarce, clean water more readily available.

The Pure Blue Tech senior management team has collectively been designing, developing, manufacturing, and implementing membrane systems for a combined 175 years since the dawn of the membrane industry in 1969.

Semilla has followed the progress of Pure Blue Tech since 2022.

Announcing an investment in Stormentum

Semilla Climate Capital is pleased to announce an investment in Austin-based Stormentum.

Stormentum is a storage-first architecture built for the electrified home. It replaces the traditional inverter and ancillary parts with a battery-agnostic system that reduces total cost by up to 30% compared to today’s typical solar & storage systems.

The Stormentum technology provides:

  • Direct battery storage integration across a wide operating voltage range
  • Higher system efficiency from reduced power conversion stages and distributed Maximum Power Point Tracking
  • Scaled system capacity through distributed power conversion

and addresses the following challenges:

  • Microinverter-based solar systems are expensive and inefficient for storage integration—requiring redundant power conversion that adds cost and reduces overall system efficiency
  • Hybrid inverter systems are inflexible and battery-limited, often forcing full system redesigns to accommodate changing homeowner needs
  • Closed ecosystems limit interoperatibility, constraining system design and reducing market reach across batteries and energy platforms
  • Proprietary workflows prevent installers from standardizing processes across jobs—driving up time, cost, and training requirements

Announcing an Investment is Skyven

Semilla Climate Capital is pleased to announce an investment in Texas-based Skyven Technologies.

The Skyven Arcturus industrial heat pump is able to achieve industry-leading performance that allows industrial facilities to significantly reduce emissions in a highly efficient, and cost-effective way. Skyven’s Arcturus system achieves a higher coefficient of performance and a higher temperature lift than any other heat pump on the market.

Semilla’s Managing Partners have closely tracked Skyven’s progress for many years and have previously made an angel investment in Skyven.
