How It Works

Five-phase execution.
No manual overhead.

01

Research

Scrape Etsy, TikTok, Pinterest, Reddit. Identify micro-niches with low competition and high purchase intent. Rank by passion intensity, community size, and virality score.

02

Generate

For each niche: 25-50 shirt, sticker, and poster concepts. AI-optimized design prompts. SEO titles, descriptions, and tags generated automatically.

03

Publish

Upload to Etsy and Shopify via Printify integration. A/B test thumbnails and titles. List 20+ products per niche in week one.

04

Content Engine

TikTok video concepts, hooks, captions, and hashtags — generated for every product. Pinterest and Instagram reels from the same asset pool.

05

Scale

Daily analytics: views, CTR, conversion. Kill low performers at 30 days. Expand winning niches deeper. Push proven products to Shopify for brand control.

Target Niches

Go narrow. Win deep.

Broad niches have thousands of competitors. Micro-niches have dozens — and buyers in those communities spend more because the product feels made for them.

Breed-Specific Pets

Dachshund mom. Corgi dad. Bernese Mountain Dog owner. Fragmented communities, passionate buyers, repeat gift purchasers.

Trade Job Pride

Electricians. Plumbers. HVAC techs. Welders. Blue collar identity runs deep — and those buyers tell each other.

Regional Humor

State pride. Local references. City-specific jokes. Evergreen demand, underserved by POD sellers chasing broad trends.

Niche Gaming

D&D dungeon masters. Specific game subcultures. Deep communities, identity-driven merch, low competition.

Family & Relationships

Mom/Dad/June - specific family role humor. High emotional reactivity. Strong gift angle, repeat buyer potential.

Micro-Hobbies

Bird watching. Knitting. Pickleball. Fly fishing. Tiny communities with big spending on identity gear.
