Plants usually start from seeds and so do plans! To make money from an idea, you need to invest money in it and this money may be in the form of a seed round or the initial round of financing you put into you new idea, deriving funds from personal assets or from venture capitalists.
For example…
An all-star investor team including the likes of Atlassian co-founder Mike Cannon-Brookes and Salesforce investor Simon Clausen helped with the seed round for Sydney-based startup, Spaceship, a mobile only super fund. Together, they raised a massive one point six million dollars in a handful of days during the seed round.
