This is a super, super mature thing to do. VCs are trying to make multiples of their investments, so the higher the valuation, the bigger your company has to be in order for VCs to make their multiple. This means you have to optimize around growing as much as possible, which increases burn rate and can screw up your priorities. If you want to build a solid, long term profitable company, it gives you more flexibility to try different things and 'do it right' rather than focus entirely on growth.
