Is being Product led as a startup enough?

Any successful team will be product-led - to a certain point. Some markets succeed with an inbound flow (product-led) while others need more external outreach to find interested users. I think it really depends on the target market and how they usually interact with users.

Considering the huge role that marketing plays in business development and customer acquisition, it would be foolish for any start up founder to disregard the importance of marketing. For some companies, such as those focused on B2B sales will have little need for marketing. But those that service the average consumers will likely always need to use the right form of marketing to get their message out to potential customers effectively.
