Growing a startup takes time, talent, and solid business acumen.
Most businesses begin from a simple idea or solution to a usual problem. Make sure that your idea doesn't end up transforming into something too complex.
Simplicity is the best. The more complicated your idea becomes, the more costly it can get. Overly-complicated explications to problems are more challenging to both market and to implement.
Start small and narrow your focus and decide what is more important.
