As a new product, how do i get a new customers?

1. Advertising. 

The key to advertising successfully is to generate promising leads in exchange for the money you spend. To do so, it helps to offer a message that not only hits on your target customers, but also showcases the value you can offer them.

2.Networking and referrals.

Landing referrals from networking or past business associations isn't just a cheap way to pick up new business. It's also a way to pick up customers with the highest retention rates. What's more, referral customers tend to purchase more over time and in turn become a source of additional referrals.

3. Teaming up.

Another way to leverage available resources is through what's known as a host-beneficiary arrangement. In this arrangement, another business with the same target customer will use their database to promote your business.

4. Strategic Alliances

You might take that partnership a step further and form what's known in the industry as a "strategic alliance." While a host beneficiary relationship is generally a one-time or short-term commitment, strategic alliances can sometimes last for many years. For instance, a Web designer and an ad agency might send each other referrals for clients who need added services.

To get new custmers or even to retain your recent ones, you have to understand the customer and the consumer behavior by making marketing research to get information and to make analysis like the idustry analysis, the environmental analysis, the porter's five forces and finally the SWOT analysis. Then you have to interpret and forcast, and finally you have to start setting the marketing strategy and to work on the brand awareness.

Good luck with that.
