- A strong case shouldn’t depend on the size of the firm.
That’s why we’re excited to announce a new partnership with HeyCounsel, bringing Rev to the solo attorneys and boutique firms in its community. Nobody has enough hours for the evidence they already have, and that’s especially true when you’re the whole firm.
- Clio runs your practice.
Rev helps you interrogate your evidence. With Rev’s Clio Manage integration, you can pull in as many matters as you need, or just the one file you’re after, and they land in Rev ready to transcribe, search, and interrogate.
