Honestly, I'd scrap everything up to $29/mth and change the pricing basis from MB and number of queries (people who use spreadsheets have no real understanding of this) to number of spreadsheets.

I remember working for Deutsche Bank 15yrs ago when one Excel spreadsheet could make them millions of £/day — don't be afraid to charge a decent amount! People who care about data, have spreadsheets, and need some interoperability will not baulk at $29, $50 or even $200/mth. And if they're giving you a decent income, they'll trust that you'll be around for longer.

Would you expect a bank (or accountant, or FMCG company) to trust a critical part of their process to a free or £12/mth service? Hell, no.

But perhaps part of the problem is that you've build a cool thing but don't know exactly who your customers should be. When you figure that out you'll be able to write more compelling copy and price it appropriately.

The only problem is that I'm almost sure that DB were making millions not thanks to the excel data per se but thanks to all the logic that was running inside/behind that Excel. In this case, you can't "APIfy" it with a tool like this.

N.B. I'm not bashing sheetlabs, just saying that sometimes the most important part is not the numbers in the cell but how you create them

I wanted to encourage people here to give it a try and get some feedback. The splash page doesn't do a great job of selling it by itself; I think you need to try it to see the value. The Free tier allowances are probably a bit generous though.

It's worth noting that the costs for this really are tiny - just a couple of servers. I've done the sums, and even with the business tier costing $20, the profit margins are significant.

The biggest unknown is how much support each user will generate, and that's probably a good reason to raise the business price. Anyone who signs up before then will be offered the existing price of course.

Based in the UK. The site already does some work with geolocating the user (for giving localised pricing and also for inferring date formats when you upload spreadsheets), so I suppose I could localise spelling too ;)

The correct English spelling is Organisation. People in America using American version of English tend to spell it as Organization.

Nearly almost every American spells it organization.

Americans also use Potato per salsa sauce or something as unit of speed.

Actually it doesn't matter - either version is correct, and in fact English spelling used organize long before it was adopted by the US.

In fact it appears more to be laziness on the part of the UK english. Whilst the 'ize' form is derived from the greek endings, certain english verbs had to end with 'ise'. As we were too lazy to remember which ended 'ize' or 'ise' we just took the pragmatic approach and used 'ise' version for all of them.
