- VCs aren't interested in "revenue tomorrow" unless you mean a 10x+ exit multiple. VCs want you you to focus on your product because there's an invisible( and sometimes not so invisible) clock running as soon as you take the investment.
- VCs aren't interested in 5-10 year tails on their investments. Most are looking for an 18mo.-3.yr ROI. If you can prove revenue and 'market traction' they'll extend your runway accordingly, however that's a constantly moving target and generally the types of VCs who are interested in the 'long tail' aren't the same that want to give you money at the infancy of your company.
- There is definitely a big difference between a traditional consultancy and a product focused organization but only in the sense of the 'end goal'. If your entire plan is to bootstrap your company by building a consultancy, it's easy to keep a separation of concerns between the two halves of your organization. Usually the "clash" that you're talking about is when a consultancy based/focused organization decides to build a product, not when a product company decides to do some consultancy.
Developers (in fact, all of technology) are considered cost centers at ALL businesses. There's not an MBA on the planet that wouldn't jettison the entire technology cost-center of their business in a heart-beat if they could figure out how to do it and still achieve their monetary objectives.
