When I worked in AWS S3, I spent a lot of time in Excel

Excel 2010 is several times faster than the latest Excel versions. What are the performance metrics compared to Excel 2010?

"We're the team that wrote the file system that powers S3." Your funding slide heading right here.

Do you sell a software or a service running in a browser? Is the computation happening on my computer or your cloud?

What I'd love to see is an easy workflow to make this supplant Google docs. Right now, let's say i want a shared spreadsheet. I need to: 1) Signup for an account 2) Create a workbook 3) Click share and put in friend's email 4) They get an invite 5) Now they need to sign up 6) They can edit my doc I'm not a paying customer (or even a user... I just heard of this), so take this with a grain of salt, but what I'd love to see is a super-friction-less way for me to share a doc and make it editable without others needing accounts. Cut out as many steps as possible above. Doing this can be a great tool for marketing... what's better marketing than easily collaborating on a spreadsheet on a site that my friend is already using and that already looks very similar to tools I'm familiar with?

Starting from a place of "I want to start providing this to my employees yesterday"... I can't see how to adopt this at an info-sec minded financial services firm that would otherwise love to pay you for it. For example, the docs show the product wants static creds for a Postgres database or signed URL for S3 bucket instead of leveraging best-practice service-to-service identity and access management. Maybe you support what I want, and I didn't find it at first glance. This either ... (a) needs to support modern dynamic or token-based authentication (e.g. Oauth2.0 client credentials grant, JWT, or for enterprises ideally CSP native IAM in Azure/GCP/AWS such as share S3 by cross account bucket permissions policy instead of signed URL, etc.), or ... (b) allow firms to operate this themselves so the spreadsheet is run in the firm's security context, no creds are shared and data never leaves…

This looks like something that I could use right away, but I wonder, since we can write Python, does this mean that we can write back to one of the native backends (e.g. Postgres)? Currently, the only way to do this from Excel (e.g. saving a snapshot of an analyst's current dashboard that they just built) is through a macro, which then starts the (understandable) descent into Excel's External Content and Trust Center permissions hell.

Your spreadsheet experience was plugged by "no first-class Python support"? What makes Python special here?

The power of excel is that everyone has it and most people have a ton of familiarity with it and there’s a million results for anything you search Google that you don’t know how to do. Basically, all the network effects, bec you’re right if excel were a new product today it would lose to every single competitor that does it much better. Are you compatible with excel functions?
