The author was doing marketing research for his boba shop and tired of endlessly scrolling Instagram to find competitors' old posts. Existing tools demanded pricey subscriptions or manual API scraping, so he wrote a script that pulled competitor posts into a table — turning an hour's work into a minute. Three weeks later he shipped the MVP at instaseer.com.\n\nFor growth, he used Claude with an Agentic-SEO-Skill to write blogs, layering in 15 years of entrepreneurship experience, and reached 10-20 Google clicks/day within two weeks. He now has 37 signups, 4 paying users and $28 MRR. Takeaway: scratch your own itch, and blogging still works as a free acquisition channel.
