"What's your company's vision in the next 5 years?"
While I used to answer this question patiently, every time potential employee or a new client or even an investor asks this question, I can't help rolling my eyes now.
Like it's difficult for a government to see through its 5 years' plans, it's difficult for a young company to put a realistic vision out even for the next 2 years, leave alone 5.
A vision is a long term plan. Any company when it starts off goes through the famous 'J' curve. You start low, go still lower along the J curve, keep on morphing and experimenting with the product, throw beta versions and MVPs (minimum viable products), set up a voracious customer feedback loop in place and then figure out the correct market fit.
It is AFTER all of this that you have can plausibly have a concrete long term vision. Anything before that cannot really be termed as a 'vision'. Those are necessary short term tasks that you, along with your small team follow in order to get a vision.
