Depending on your stage, type, and number of investors, you may need to use different formats for your reports. Email newsletters are simple and concise, making them easy to send to a large group of investors. Tools like Mailchimp or Substack can help create and manage newsletters, which are ideal for early-stage startups, angel investors, and crowdfunding backers. Dashboards are interactive, visual, and data-driven platforms that allow you to share key metrics with your investors. Platforms like Google Data Studio, Klipfolio, or Baremetrics can be used to create and update dashboards, which are best suited for growth-stage startups, venture capitalists, and sophisticated investors. Presentations are formal documents that cover all aspects of your business. Platforms like PowerPoint, Google Slides, or Pitch Deck can help create and share presentations; these are great for late-stage startups, institutional investors, and board members.
