One Trillion spent on AI Capex in 2026, the story isn't in chips alone.
For every $100 flowing into the supply chain

- $1 to forgings
- $3.6 to sheet metal parts
- $2 to Plastic
- $2.4 to CNC machining
without these manufacturing technologies, the rest isn't even possible.
50. Bedrock Energy - Deep-drilled geothermal heating and cooling for buildings
Key People: @joselyn_lai, Silviu Livescu
Stage: Series A
Founded: 2022
Bedrock Energy builds geothermal heating and cooling systems for commercial buildings and communities, using deeper boreholes to shrink the land a system needs. It completed a retrofit at an Austin office building and is building district systems in Colorado and Utah.
Today, we are excited to announce the first annual Austin Deep Tech 50.
Austin has become the hub for some of America's best deep tech founders, so we brought together 8 VC firms with a local presence — @overmatchvc, @valor, @8vc, Banner VC, @BCapitalGroup, @TheAmbitionCap, @ensemblevc, and Trust Ventures — to vote on the 50 startups making the biggest impact.
Together they've raised $10B+ in the last 12 months.
