San Francisco based grocery delivery startup, Instacart, has raised a $200 million fund round led by Coatue Management.

The company provides its customer base with a mobile app which can be used to order groceries directly to users’ homes. The startup works with approximately 200 retailers such as Costco Wholesale Corp and Target Corp.

Instacart had previously partnered with Whole Foods with whom the company signed a deal in 2016. The grocery chain was recently purchased by Amazon making the company a competitor for the startup.

The startup, now valued at $4.2 billion according to the company, will use funds for resources in their competition with Amazon. Sequoia Capital, Andreessen Horowitz and Whole Foods Market previously invested in the company along with others.

Amazon recently began testing its own grocery delivery service for Whole Foods groceries, so far available in a few cities in the US.

Instacart is also partnered with companies such as General Mills Inc, Coca-Cola Co and Pepsico Inc to bring in income via promotions and coupons for their customers. The startup also brings in income via its delivery fees.
