Terra AI uses AI to learn more from geological data, accelerating discovery and development of critical minerals and energy resources, wedging into a conservative industry via probabilistic 3D subsurface models that tell operators where and whether to drill. The platform integrates geophysics, geochemistry, and drilling data to generate millions of geologically realistic models and quantify uncertainty in minutes, spanning mineral exploration, enhanced geothermal, and carbon storage.
Founded by two Stanford Intelligent Systems Lab PhDs, Terra advanced early pilots (Shell, OMV, California Geological Survey) into signed engagements with OMV ($550K, two-year) and the CGS, plus a growing commercial roster across copper, gold, and rare-earth projects; by the 5/26/25 call it reported royalties of $5.4M booked value and $400K cash fees. StoryHouse committed $250K via StoryHouse SPV - Fund I into the Khosla-led $15M round at a $50M valuation (10 LPs participated; official amount sent $249,998.22), closed 2025-10-10. Internal Airtable Notes (2/25/26) record a subsequent $4M BHP convertible note at a $100M cap, and the round was publicly announced as a $20M Series A led by Khosla Ventures with strategic investment from BHP Ventures on 2026-06-03.
Terra sells into a specialized but fast-growing wedge of the broader AI-in-mining market, driven by surging demand for critical minerals, declining success rates of conventional exploration, and maturing ML able to integrate multi-source geological data at scale. Web
| Company | Approach | Note |
|---|---|---|
| Terra AI | Generative probabilistic 3D subsurface modeling; software / decision-support layer | Customers BHP, Rio Tinto, OMV; copper / gold / REE / reservoir |
| KoBold Metals | AI targeting plus its own asset development and drilling | Best-funded comparator; Mingomba copper proof point |
| Earth AI | Targeting software plus in-house drilling fleet | Detection to drill-test in 3–6 months |
| VRIFY | Prospectivity mapping software (DORA / Predict) | Direct exploration-software competitor |
| VerAI | AI asset generator; project ownership / carried interest | Monetizes via equity, not software seats |
| Seequent, SLB | Incumbent modeling tools (Leapfrog, Petrel) | Legacy workflows Terra augments / displaces |
Moat: proprietary probabilistic AI rooted in the founders' Stanford Intelligent Systems Lab research, deep multi-source data integration, and strategic data-and-customer relationships with mining majors (BHP, Rio Tinto) that create high-touch enterprise lock-in. Web
Pilots with OMV and the California Geological Survey converted into paid contracts (Shell was in paid-pilot negotiation as of late 2023); the Series A announcement calls out junior miners as a priority expansion segment. Web
Most probable acquirers are the strategic investors and customers already in the cap table and pipeline: BHP and Rio Tinto, alongside subsurface-software incumbents such as SLB. KoBold Metals stands as the best-funded private comparable validating that AI-led exploration can translate into economic mine development. Web
Khosla Ventures term sheet execution: signed exploding offer last Wednesday for a $15M round. KV wants full $15M allocation net of pro rata. Lead partners Rajesh plus one climate-practice partner (Ian, Alice, or Jesse). Currently in legal diligence, targeting first-close allocation by September 12.
Potential co-investors: considering General Catalyst, Bessemer, or Lux for a $1–2M allocation, carved from KV's allocation rather than added to the $15M. All are potential Series B lead candidates; Lux partner Shaheen most engaged in mining. Risk: if a co-investor does not lead the Series B it creates negative signaling. John leaning toward inclusion despite the risk.
StoryHouse allocation: $200K pro rata confirmed; Miles requested up to $1M if additional allocation becomes available. John unlikely to reduce other investors' pro rata. Pro rata described as earned, not given. SPV structure no issue. Next steps: schedule an LP call, target all participants papered with Cooley by September 12.
Source: Meeting Notes recP0chM0mmN1Me8IReceived a term sheet for $15M on a $50M valuation from Khosla, with a 24-hour deadline. Board composition would be two Khosla, two Terra, and one independent, possibly Vinod as a new member, but unclear. Option pool of 15% comes from the post-money.
Other firms in progress: Evoke and Clean Energy Ventures, being called to see if they can move quickly. Summary: good news for Terra; StoryHouse has pro rata allocation to discuss.
Source: Meeting Notes recrsXhxmandVewIBThe Energized VC offer fell through. Terra is considering downsizing the round size, with runway until January 2026.
Talked through a smaller fundraise process, Khosla dynamics, and business-model framing (SaaS with large players versus capturing a piece of the upside with juniors), plus messaging to existing and prospective VCs. Asked to do a run-through of the new deck later in the week.
