One-Liner & Thesis

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.

Investment Score & Recommendation

77 / 100
INVEST
Biggest driver: a top-tier syndicate (Khosla, BHP Ventures, Rio Tinto) attached to a defensible technical team riding a strong critical-minerals tailwind. Biggest drag: modest absolute revenue (~$1.7M LTM) and long, conservative enterprise sales cycles in mining and energy. Healthy Funded holding with strategic validation and an early paper markup.

Return Scenario
$50M entry vs $100M cap note (2/25/26)

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

Latest Meeting Notes

2025-09-04 Call KV term sheet execution & SH allocation Expand
Miles with Anthony & John. Khosla signed an exploding offer for the $15M round, now in legal diligence targeting a first close by September 12; StoryHouse held $200K pro rata with a request for up to $1M.
  • Round: KV wants the full $15M allocation, net of pro rata; leads are Rajesh plus a climate-practice partner.
  • Co-investors: weighing General Catalyst, Bessemer, or Lux for $1–2M as a potential Series B lead; signaling risk debated.
  • StoryHouse: $200K pro rata confirmed, Miles requested up to $1M; SPV structure no issue.
Full note

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.

2025-08-26 Call Khosla term sheet: $15M on $50M Expand
Terra received a Khosla term sheet for $15M on a $50M valuation with a 24-hour deadline; StoryHouse confirmed it holds pro rata allocation.
  • Terms: $15M on a $50M valuation; board of two Khosla, two Terra, one independent; 15% post-money option pool.
  • Other firms: Evoke and Clean Energy Ventures being pressed to move quickly.
  • StoryHouse: confirmed pro rata allocation, flagged to discuss.
Full note

Received 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.

2025-08-11 Call Energized offer falls through; downsizing Expand
The Energized VC offer fell through, prompting Terra to consider downsizing the round; runway ran to January 2026.
  • Setback: Energized VC offer fell through.
  • Response: considering a smaller round; runway until January 2026.
  • Advising: talked through Khosla dynamics and SaaS-vs-upside business-model framing.
Full note

The 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.
