Was Rasyn tut

We builds foundational AI models for chemistry. Almost nothing you buy is a single chemical. Products like datacenter coolant, GPU thermal paste, paint, and glue are formulations, which are mixtures of around ten ingredients each, and demand for them has grown quickly because of AI and EVs. Designing a new formulation is essentially a search problem, because there are more possible mixtures than anyone could ever test, and none of them can be predicted in advance. As a result, bringing a single formulation to market today takes three to five years of trial and error in a lab. Our models predict how a mixture will behave far faster than the standard methods used today, which lets us design new formulations in weeks rather than years, at a fraction of the cost. To prove this, we used them to invent three chemicals that never existed before, including a PFAS-free coolant for datacenters, and we have since synthesized and patented all three. We are already working with some of the largest manufacturers to design formulations for them, and we are building our own lab to generate the data that will train our next models.

Rasyn

Describe what your company does in 50 characters or less.

Foundational AI models for chemical formulations.

What is your company going to make? Please describe your product and what it does or will do.

We build AI models that predict how chemical mixtures - formulations - will behave, so R&D teams can invent and test new products in silico before ever stepping into a lab. Today, making a new coolant, paste, or glue is a years-long process full of trial and error. With Rasyn, manufacturers can go from concept to a working, manufacturable chemical in weeks. Our models are already used to create real, patented substances, including a PFAS-free coolant for datacenters.

Where do you live now, and where would the company be based after YC?

We live in San Francisco, CA. The company is based in San Francisco.

Explain your decision regarding location.

San Francisco has most of the people we need to hire and is a hub for both AI and deeptech. We need access to talent in both chemistry and AI; our customers are also here.
