Building a strong relationship with your first hundred customers can lead to organic growth as they share their passion with others.

Building growth into the product from the start is crucial, rather than treating it as an afterthought after initial user acquisition.

The best companies grow through word-of-mouth rather than paid acquisition, and in the early days of a startup, if you lack funds, focus on growing your business without spending money by doing things that don't scale. This organic growth is a sign of a strong product that resonates with users.

The first task for a startup is to build a product that some users love, as this is crucial for long-term success.

Organic growth, which is growth that doesn't require payment, is often neglected by founders. For example, at Monzo, we reached a million customers before spending on direct marketing or advertising, primarily through virality and network effects.

Focus on building deep relationships with your first 1,000 users; this will help ensure your product truly meets their needs and can scale effectively.

Creating a product that a small group of users absolutely loves is more valuable than trying to please a larger audience with mediocre features.

Once you have a product that users appreciate, expanding your market becomes easier; starting with a niche can lead to broader adoption later.

Instead of finding a ton of people who like your product, focus on finding 10 to 20 customers who truly love it, as growth comes from great products, not the other way around.
