That's the problem with VCs in general, and it doesn't fit their business model from a math perspective if you are low-growth. There are some investors who are trying a new model (see Indie.vc). The alternative is either to go without funding (at the expense of an ad or subsciption model), or have your users help fund you through something like an ICO or equity crowd fund or patreon etc. Or you find a way to remove infrastructure costs through some technical decentralization or open-source and treat development/support as a hobby, but that doesn't scale to this size.
