What happened

Geothermal startup Mazama Energy raised $135 million to drill three miles underground into superhot rock. The company is developing wells capable of generating 15 MW of electricity continuously.

Why it matters

Deep geothermal energy is attracting significant capital to scale baseload clean power for energy-intensive sectors. Securing $135 million allows Mazama to tackle the steep engineering costs associated with deep-strata drilling where conventional geothermal systems fail.

What to watch

Drilling progress and thermal conversion efficiency during field tests as the company attempts to demonstrate continuous 15 MW power generation.

Molagri raises $5.2M Seed round

Molagri raised $5.2 million USD in a seed funding round. The funding will support hiring scientists and conducting field trials for its evolving pesticides.

Why it matters

Biological and evolving pesticide alternatives require multi-year R&D and strict regulatory compliance, making early capital critical to clearing initial efficacy gates. Directing seed funds toward scientific hiring and field trials moves the core IP from lab validation toward initial commercial proof points.

What to watch

Field trial data milestones and regulatory filing timelines for Molagri's pesticide formulations.

Kairos Power Raises $643M for Reactor Construction

Nuclear-energy startup Kairos Power LLC secured $643 million in private and government funding. The capital will support the construction of its demonstration reactor in Tennessee.

Why it matters

Commercializing advanced nuclear technology requires massive, blended capital structures combining public grants with private equity. Securing over $600M moves advanced reactors from regulatory concepts into capital-intensive physical deployment.

What to watch

Construction timeline milestones and regulatory clearance progress for the Tennessee demonstration reactor.
