A nicely designed proposal is one of the secret to steal your investor attention, or just everyone else.
Design Statement: Proposal is one of the example, by presenting it with user engagement in mind we start it from the front: a knot.
Next is the paper. A yellowish one give it a warm feels on the eyes, the light-weightness give it a touch of lux.
Using a boundless format this proposal will ease your nerve like a morning newspaper.
But beside the design itself a prospective proposal must have contents that as brilliant as diamond and as clear as crystal to make it work.
Goodluck with your proposal-thingies! And don't forget, a solid team is the best foundation.
