User reviews

Useful, easy to use solution

I love the app simplicity and how it helps me with all my small business agreements and payments management.

My New Favorite Business Tool

Exactly what small businesses and creators need. I’m constantly managing collaborations, invoices, bookings, and agreements, and this app makes everything feel so much more organized and professional. The AI assistant, payment tracking, reminders, and built-in agreements save so much time and eliminate the awkward back-and-forth. The interface is sleek, easy to navigate, and feels premium compared to other platforms I’ve tried. You can tell this app was designed with modern entrepreneurs in mind. Excited to keep using it as it grows!

Founder

I need this in my life!! Other signing tools have gotten was too expensive, especially for small to medium size businesses.
Also, love the functionality and the look and feel of this consumer app.

SMS doesn’t work

You cannot advance further in registration because the sms is never delivered

So helpful

This app needed to exist, it’s so easy to navigate and I’m using it to meditate a very challenging landlord tenant situation right now as an escrow and / or contract substitute. Brilliant.
