I'm looking for tools that replace the use of Spreadsheets and PowerPoint. Ideally, it should touch on Business Strategy, Customers, Product, Market and Growth Experiments.
I love using Canny for product management because it helps me quantify user interests in feature requests. As a single developer with a ton of feature requests to go through, it's hard to quantify what users want. Canny lets users vote on their favorite feature requests so I can know what users want most.
