There appears to be a bug on the Column.com contact form after signing up.
Number of employees is pre-populated with a range (e.g. 2-5) based on initial question, but trying to submit the contact form gives a NaN error with "Please match the requested format" but is not editable.
Do you have a public dev environment where people can test it out and work on building apps on top of it?
I’d love to experiment with using column to replace my banking and payments for my consulting business.
