Rowzero seems incredible, but this and PySheets target the wrong users. You are targeting data scientist while I would target finance people to get traction. So let me tell why I would use it as a Data Scientist but not as a finance guy: 1) It runs on the cloud, I would go with something that runs locally (or on premise) since there are sensible data there (with rust as a backend should be fine, python you need to ship a set of libraries using docker) or should be integrated into GCP/AWS/Azure. 2) You need to create a PowerPoint/Word alternative as well where you can just copy/paste stuff or you need to make the copy/paste in PowerPoint/Word easy 3) Push strong on big data and DB connection, right now those are the bottlenecks, also create some API in python for popular services in finance (Bloomberg, Factset, CapitalIQ, ...) so that they are available out of the box with a subscription 4) Do something for the text part, like getting embeddings for similarity, fuzzy match in python plus probably the interface can be different in analyzing text (highlights in green of keywords, search in text and so on), people in finance often work also with PDF and having all in a platform is nice instead of having two windows as of today
