I have a landing page setup, do I develop the site further (be able to offer the product) and then upon order completion capture details? or leave it as a simple landing page with EOI capture (email)? (the former would entail additional spending as I am not a dev)
I have worked with startups for more than 15 years, mostly as a seed stage (pre revenue) VC.
More and more, funders and other stakeholders look towards third party proof points (e.g. users). If you can build a mock up or MVP great, but even a simple landing page with EOI proves that what you are working on may have legs.
Better to test, early and often is what the Lean Startup teaches us. Once you have proven something, only then move on, invest more, and build out. First search for problem/solution fit, then product / market fit, then scale.
If you'd like to discuss, drop me a follow up note and I can share more thoughts and resources.
