Our Story

When Jason (our CEO) began his career as a corporate lawyer in 2007, one of his first assignments was performing a definitions check on a loan agreement — finding "Defined Terms" that were never used, and capitalized terms that were never defined. He understood the necessity of the task, but was surprised that no standard procedure existed to perform it.

One evening, around 9PM, a request came in to perform the definitions check and have it reflected in the next morning's draft. Due to other pressing assignments, Jason started the check around 2AM and finished around 4AM. He submitted the work, but it was too late; the revised document that came out in the morning did not reflect his findings. After being yelled at, he wondered if someday this process could be automated, the way redlining and spell checking had been.

When Jason left law practice to start Celant Innovations, he revisited the pain points of modern corporate practice. After learning that the latest technology had not flowed through to defined-terms checking, DefCheck.com was born. After 18 months of continuous refinement against actual commercial agreements, the algorithm produced reliable results and was granted U.S. Patent No. 10,713,482 on July 14, 2020.

DefCheck.com is a simple and reliable tool to automate defined-terms error detection. Alongside the fully highlighted document, DefCheck produces a prioritized findings report — so confirming the errors takes a practitioner minutes, not hours.

What makes DefCheck different

It is patented.

The core detection method was granted U.S. Patent No. 10,713,482 in 2020 — the product of 18 months of refinement against actual commercial agreements before launch, and continuous improvement since.

Measured against real lawyer work, not synthetic tests.

Every change to DefCheck's engine is benchmarked against SEC-filed credit agreements, merger agreements and indentures reviewed line-by-line by a practicing securities attorney. DefCheck surfaces over 98% of the issues the human review found — while filtering out the noise (tables of contents, section headings, signature pages) that makes naive term-checkers exhausting to use.

It has read more contracts than any associate ever will.

DefCheck's suggestions draw on a research dataset built from 7,200 SEC-filed contracts, in which human reviewers individually examined more than 30,000 flagged terms and recorded the correct resolution for each. When your draft says "Issuing Bank" but defines "Issuing Lender," DefCheck doesn't just flag the term — it tells you which defined term you probably meant, and how often that exact slip has appeared in other agreements.

Built for the AI era.

Every check produces an analysis report designed to be pasted directly into an AI assistant such as Claude or ChatGPT, with the context, evidence and instructions the AI needs to act like a trained reviewer. In our blind tests, an AI assistant working from DefCheck's report reproduced roughly nine out of ten items on the expert attorney's final review memo — including some the expert missed.
