Scientists first
Every decision we make starts with the question: how does this help scientists do better research?
We are a team of scientists and engineers
We build AI for scientific instruments because we've worked with them firsthand: in the lab, in the field, and in the enterprise.
Our story
The idea for Rayni came from firsthand frustration. Sakshi spent years working alongside top physicists at Fermilab, watching brilliant researchers waste countless hours searching through 1000s of pages of manuals, waiting days for manufacturer support, or relying on the one person in the lab who happened to remember how to fix a particular issue.
She teamed up with Divyanshu, who had built enterprise platforms serving millions at CrowdStrike and Visa, and Shahadat, who had sold and supported instruments in the field at MOBILion Systems. Together, they had the rare combination: deep scientific empathy, enterprise engineering, and instrument industry experience.
They built Rayni to be different: an AI that only answers from verified sources, cites every claim, and learns your lab's specific procedures. Their unique industry fit led to Rayni winning the New Venture Challenge, a top-ranked accelerator in the nation (Grubhub, Venmo, Simple Mills).
Our values
The principles that guide everything we build.
Accuracy over speed
We never compromise on the accuracy of our answers. Every response must be verifiable and cited.
Privacy by design
Your data is yours. We build security and privacy into everything we do from the ground up.
Transparent AI
No black boxes. We show our sources so you can verify and trust our answers.
