2 fundamental ideas: Distribution & Supply Chains

Distribution:

You need to secure distribution before your company can grow. Which means essentially a lead list or people you can reach in bulk or manually by walking down the street. You need at least 500+ such connections.

The goal of the initial distribution is iterating on your core value proposition. Core value proposition is a binary statement which should be answerable by hell yes or no by your distribution. So iterate on the statement on the first 100 till you get to a hell yes on the binary question. That question should also become the heading of your landing page above the fold.

Supply Chains:

To deliver the product you need to think in supply chains. If you have played factorio or such games this will make more sense to you.

You need a constant supply chain of potential customers (distribution from above). You need a constant supply chain of great employees. You need a constant supply chain of new income streams in your product.

A good product delivers value at first touch. That is through strong UX and clear demarcation. Every feature should exist to deliver the core value. So you need to reject a bunch of designs, product ideas, customer feedback to make sure that you are only delivering value.

Other thoughts:

I can only speak of core technology businesses. If you are selling data, you are not a tech company, stop acting like one. Just put stuff in a spreadsheet and sell that.

Use a strongly typed language like Golang or a highly expressive one like Ruby for your backend. Choose extreme languages such as Imba or Steel Bank Common Lisp (which I built on initially before switching to Golang) for maximum advantage.

Make sure that you have a potential market of at least a $100 million flowing through.
