One of the best SaaS websites I've seen. Lets you play with the tool as much as you want without signing up and the business model is totally aimed at businesses with a very generous free tier. Chart tools seem very powerful as well.
Pretty steep from free to $5990 per year. That's a lot of money for startups etc, but they can stick to the free tier. I'd be worried if the free tier suddenly changed though, but I doubt they'd do that to their potential customers. All in all I'd be willing to try this out.
That’s $50/seat/month if you have 10 seats and marginal seats are $21/month. Feels fine if lots of people will use it. Perhaps they are trying to avoid doing support for tiny customers.
