The short answer
Product-led companies get most of their new users from two places: organic search (about forty percent) and product virality (about sixteen percent), so build for those two deliberately. On search, the winning patterns are free sidecar tools, template libraries and programmatic pages built from your own data, which is how Zapier, Airtable and Snyk got their reach. On virality, reduce friction on sharing and inviting until it is a single click, and make the artefact your user creates something they want to send to someone else. Pick product activation as your north star, not signups, because a signup that never reaches value costs you money. Postman is the Indian example worth studying: distribution through the tool developers already used, not a sales team.
