Rubric AI
's Moat:
Open-source agentic frameworks (used by Cal.com, Trigger.dev) build community adoption. Rubric-based reward models are a structured approach to alignment that most labs implement ad hoc. Staff Payments Lead at Meta across Instagram, WhatsApp, and Facebook demonstrates the ability to ship production systems at massive scale.
How They're Leveraging AI
AI Use Overview:
Using rubric-based reward modeling for LLM evaluation, academic review simulation for paper feedback, and agentic AI orchestration for alignment workflows.
Aemon
Autonomous AI engineer that discovers better algorithms than DeepMind at a fraction of the cost.
Beat DeepMind's AlphaEvolve on an NP-hard problem for under $10 in compute. If that result generalizes, Aemon sells automated R&D to quant funds and biotech labs at a fraction of what they spend on human researchers.
ARC Prize Foundation
Defines how the world measures progress toward artificial general intelligence.
Chollet wrote the benchmark every frontier lab uses to measure AGI progress, and now he controls the next version. That gives ARC Prize a chokehold on how the industry defines and funds intelligence research.
Doomersion
Turns doomscrolling into language learning with adaptive video feeds and clickable subtitles.
Duolingo gamified language learning. Doomersion replaces doomscrolling with it. Adaptive video feeds of native content with clickable subtitles, built by a founder who self-taught Japanese through 6 years of immersion and understands how acquisition actually works.
Librar Labs
Gives the 98% of schools without a library system an AI-powered cataloging and search platform.
98% of schools worldwide lack a proper library system. Librar collapses cataloging from weeks to hours using camera-based bulk scanning and a self-healing data backend. The niche is small but uncontested, and the data asset (structured literary metadata) compounds.
