1. Use a standard multiple on revenue for you industry, e.g. 3x for SaaS, conservatively estimate your revenue in 5 years (be realistic), and multiply. Then divide that result by 10, I.e. investor wants a 10x ROI, and that’s a good starting point for a valuation cap.
2. Modified Berkus: Start with a $2 million basis, then add up to $2 million based on relative experience of the team, up to $1 million for the status of the development/market readiness, up to $2 million for the sales pipeline, and up to $1 million for other factors. You can also add $1 million per $500k of revenue if you have it. That’s a good starting point.
