You're really limiting your userbase (customer pool) here by expecting only enterprise users. Many people here are freelance designers, students with part-time jobs, researchers writing for-profit books, or they work for themselves. Most employers don't allow expenses for note-taking apps.

It looks cool, but I won't buy it until it's a lifetime license.

Edit: Sorry that this came out overly-negative. It's a beautiful product, congrats on launching it!
