Altara secures $7M to bridge the data gap that’s slowing down physical sciences

Companies working on batteries, semiconductors, and medical devices generate vast amounts of data — much of it ends up scattered across spreadsheets and legacy systems, making it hard to use to improve products or understand failures.
San Francisco‑based startup Altara, which just secured $7 million in seed funding, says it has built an AI layer designed to bridge these data gaps and bring fragmented technical information into a single platform.
Funding round
The seed round was led by Greylock, with participation from Neo, BoxGroup, Liquid 2 Ventures, and Jeff Dean.
Founders
Altara was founded in 2025 by Eva Tuecke, who previously conducted particle‑physics research at Fermilab and worked at SpaceX, and Catherine Yeo, a former AI engineer at Warp. The two met while studying computer science at Harvard University.
The problem and Altara’s solution
“Imagine you’re a company building next‑generation batteries, and a battery fails during the cell testing in the R&D process,” Yeo explained. “A team of engineers has to go in and manually check a lot of different sources of data, anything from their sensor logs to their temperature data, moisture data. They cross‑check historical failure reports.”
Scientists and engineers often spend weeks or months on this “scavenger hunt” across a multitude of data sources just to diagnose and resolve failures. Altara claims its AI dramatically slashes the time required for this process, condensing weeks of manual data triaging into minutes.
Industry perspective
Corinne Riley, a partner at Greylock, compares Altara’s work in the physical sciences to the role of site‑reliability engineers (SREs) in software. If a system fails, “an SRE will go in and look at the observability stack of the company,” she said. “Someone pushed a change to the code, and that’s what caused an outage.”
For context, Greylock‑backed Resolve, valued at $1.5 billion, uses AI to diagnose software failures. Altara’s vision is to act as the hardware equivalent, determining exactly what went wrong when a battery or a semiconductor wafer map fails to perform.
Related startups
Altara isn’t the only startup using AI to accelerate development in the physical sciences. Startups like Periodic Labs and Radical AI are also tackling scientific research from the ground up.
Altara takes a different, less capital‑intensive approach: rather than trying to replace decades‑old research and manufacturing firms, it provides an intelligence layer that plugs into their existing data.
