Lack of time is one of the typical issues founders face. Contacting investors takes time and is undoubtedly crucial. Since time is ultimately the most valuable resource, I am happy to see a tool that can help entrepreneurs save a significant amount of time.
Based on our record, Portfolio Performance seems to be more popular. It has been mentiond 1 time since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
To keep track of investment performance I use the open source tool PortfolioPerformance. It’s stored locally and not in the cloud (like an excel sheet) and gives a pretty nice interface with stats and graphs. (See: https://portfolio-performance.info). Source: about 2 years ago
