Often there is important insight and market detail in a deck, especially first-financing deck, that could help a fast follower, so you wouldn't want it shared widely.

But in the end there's a big, big difference between idea an execution, and if a fast follower could get it from a deck, perhaps there isn't much differentiation in what you do.

Decades ago I was advised to act as if any competitor had full access to our internal systems (payroll #s, marketing plans, the works) and assume that prospects and customers not only don't know anything about what we do but also that they could not care less. I've taken this to heart.

For my current company (self-funded for the past year, raising about the same size seed round now) I have a goal of 1/3 strategic partner, 1/3 customer, 1/3 professional investor. But I know if I get a professional investor(s) to cover more than 1/3, or all of the round I'll just take it and move on to the next task. Fundraising always takes too long and is too distracting to try to optimize on this scale at this point in time.

A strategic investor is extremely rare at the seed stage, and for many of the reasons that it is rare, it usually a problem when you do it. Our plan is a very special case...but still it's unlikely, despite expressed interest.
