During the initial stages of growth, a bootstrapped startup should focus on both getting more customers and making a few customers really happy.
Closing every customer and providing them with utmost attention is crucial, regardless of their size.
Having happy customers, even if they generate less revenue initially, helps pave the path to acquiring more customers and stimulates word-of-mouth marketing.
HubSpot's success demonstrates the significance of word-of-mouth, as 33% of their customers came through this channel.
