Internal stakeholder updates can make all the difference between alignment and chaos.
Be sure that your investor update emails (and internal stakeholder updates of all kinds in fact) start with clear charts to show key KPIs and include Highlights, Lowlights and What's next.
Ensure each section is concisely written with bullet points that contain key facts and implications without too much fluff.
Be sure to be real so that your stakeholders can help you when possible and aren't blind sided if things go off the rails.
