Build a portfolio of tiny, hyper-specific Chrome extensions that each do one narrow data-extraction job (e.g. extract emails from a page, scrape Shopify bestsellers, pull data from Redfin) named literally after their high-volume target keyword. Each ranks for its keyword, offers a free tier plus usage-based paid tier with email nurture, requires minimal maintenance, and forms a holding-company portfolio of cash-flowing micro-tools.
Opportunity7.1
Why now
AI/offshore teams make extensions cheap to build (~$3K in ~3 weeks), and high-volume keyword demand with weak named competitors persists; SEO + exact-match domains still rank easily.
Market gap
Long tail of narrow 'job to be done' extraction needs (Redfin, Shopify, emails) underserved because builders chase big tools (Honey, Grammarly) instead of tiny literal-named utilities.
Business fit
Type
Micro-SaaS (Chrome extensions)
Target
People needing to extract specific data from sites lacking APIs
Revenue
$10K/mo per tool; portfolio of 20-100 tools; single tools cited at $50K-$300K/mo
Founder
Solo developer/engineer building a portfolio holding company; ideal first product for a technical founder.
