About Us
Why we're building Cardinal
Feature-block
Hi all - Devi and Jianna here! We first met in 2023 and built our first company together, Leafpress (YC S23), an energy management platform. At its core, Leafpress parsed utility data for customers - and the hardest part, by far, was processing utility bills.
Some were handwritten, others covered in annotations, and nearly all of them were formatted completely differently. Every line item mattered, and preserving the structure was critical - otherwise, account numbers wouldn't match usage data, and things would fall apart.
We spent countless hours manually reading bills, trying every solution on the market. In the end, we cobbled together a multi-step, human-in-the-loop pipeline… and still got inaccurate results.
So we built the tool we wish we had: Cardinal - a new OCR engine born from those painful lessons. It's everything we needed back then, and everything we couldn't find anywhere else. For healthcare companies, where fax is the most common means of communication, having a good document intelligence engine is critical.
We're excited for you to give it a try - and we'd love to get your feedback! Email us at devi@trycardinal.ai or jianna@trycardinal.ai
