some strategies to acquire the first few customers

you should understand your customers better – what they want and do you have a product they need ?

understand the pain points and try to resolve them with your product / service

you also need to learn to price your product / service optimally

your product / service will not solve all problems for all people – the faster you understand this – the better

you could give away your product for free to some people and take their feedback , incorporate it to improve your product

try to find a customer who can give you a long term revenue – rather than a one time sale – it costs more to acquire a new customer than keep a customer
