“I was facing a 12–15 hour prep for the deposition of the person most qualified to testify at a major manufacturer in a lemon law case. Using TrustFoundry, I had a great 33-page document that covered all topics within a few minutes. I was also very happy with how the questions were worded. TrustFoundry turned this multi-day depo prep into less than 3 hours of work.”
