Tailscale has raised $160M

If they had taken just say $40 million would they be able to sustain their project for the foreseeable future and perhaps not yield as much future product direction and equity?

I honestly don't know how this big dealmaking works but it strikes me that when you take out this big of an obligation that the obligation has a gravity that may drag you in a direction you (or consumers) do not want to go.

Love Tailscale as a product (as does everyone I talk to) but genuinely want to learn more about the trade-offs as usually when we see big dollar signs all we do is celebrate.

One of the main problems with raising too much is that you stop caring about product-market fit and can go on tangents that do not make you competitive. This is quiet common afaik.

Yes; you will burn through all the capital you raise in ~18 months. It is _extremely_ difficult to efficiently allocate large raises (100M+) in 18 months. In fact, I’m developing a pet thesis that no single human or business can efficiently allocate more than $100M. This would imply that any time a single raise is more than 100M, the investors always would have had a better return by splitting it into chunks of 100M or less. It’s not a _good_ thesis yet, just one I’m performing thought experiments with
