We increased prices at 80legs from on-demand ($2.00 per million pages) to subscription + on-demand (starting at $99 per month + $2.00 per million pages).

It was a success for us. Here's why:

1. It was early on - just a few months after our public launch.

2. We offered a limited free version in conjunction with the price increase.

3. We lost some customers, but they were only worth max $10 per month. We were able to work with some of those customers to setup custom plans that met their needs.

4. The customers we did keep went from being worth $50 - $100 per month to $100 minimum per month.

5. Our major competitors charge thousands per month, so we were still absurdly cheaper than them.
