## Summary

US YC S23 AI materials discovery at 10x acceleration with Aperam (specialty steel) partnership Oct 2024; $3.1M from YC/Singular/Kima/Collaborative Fund competing with Citrine for AI-powered industrial materials R&D.

## Company Overview

Osium AI is a United States-based AI materials discovery platform — backed by Y Combinator (S23) with $3.1 million in total funding including a $2.6 million seed in 2023 from Y Combinator, Singular, Kima Ventures, Collaborative Fund, and Raise Phiture — providing materials R&D engineers and industrial companies with AI software that accelerates the discovery and optimization of new materials by 10x, predicting physical and chemical properties of candidate formulations before laboratory synthesis. Founded in 2023 by Stanford University friends Sarah Najmark and Luisa Bouneder, Osium achieved a partnership with Aperam (a global stainless and specialty steel producer) in October 2024 and partnerships with leading research institutions in November 2024 — validating the platform's utility for industrial materials development.

Osium AI's materials discovery platform addresses the cost and time inefficiency of traditional materials R&D: discovering a new steel alloy, polymer formulation, battery material, or catalytic compound through conventional trial-and-error laboratory methods requires synthesizing and testing dozens or hundreds of candidate formulations — each synthesis run costing thousands of dollars in materials and equipment time, and the iterative testing feedback loop taking months to converge on optimal compositions. Osium's AI models (trained on materials science literature, experimental datasets, and first-principles simulation data) predict how candidate material formulations will perform on target properties (strength, thermal conductivity, corrosion resistance, electrical characteristics) before laboratory synthesis — allowing R&D teams to down-select from 100s of candidates to the 5-10 most promising formulations for experimental validation, compressing the materials discovery timeline.

In 2025, Osium AI competes in the AI materials discovery, computational materials science, and industrial R&D automation market with Citrine Informatics (materials AI, $42M raised), Kebotix (AI materials discovery, $14M raised), and Schrodinger (NASDAQ: SDGR, computational chemistry platform, $200M revenue) for industrial materials company and research institution AI-accelerated materials development platform adoption. Collaborative Fund's investment reflects sustainability materials investment thesis (advanced materials for clean energy and climate applications). Y Combinator S23 backing connects Osium with the materials science AI and deep tech investor community. The Aperam partnership (Aperam is a Luxembourg-listed steel company with €5B+ revenue) validates commercial deployment in the specialty metals market. The 2025 strategy focuses on growing the European industrial materials company partnerships in steel, advanced ceramics, and specialty chemicals, building the active learning loop (AI-directed experimental design for faster property data collection), and expanding to battery materials discovery for the EV and energy storage market.
