Most side hustles fail because founders build first and ask later. Validation flips that order.
Write a one-sentence offer: who it helps, what outcome you deliver, and the price. Share it with people in your target audience. Ask what they already tried, what they would pay, and whether they want to buy a first version.
If three or more people say yes to a paid pilot — or you collect pre-orders — you have enough signal to invest evenings building. If not, adjust the offer before you spend on logos, inventory, or ads. For more guidance, see how to start a side hustle while working full-time and build a simple system to grow your side income.
