Price Tracking Browser Extension

The idea

A browser extension that tracks prices on products you view and alerts you when they drop, monetized through affiliate commissions.

Verdict: PASS 28/100

The core product is commoditized with entrenched competitors (Honey, Rakuten, CamelCamelCamel) who have scale, brand trust, and affiliate relationships locked in. A solo founder has no distribution advantage and would be competing on pure feature parity in a race-to-the-bottom affiliate model.

Tribe

casual online shoppers who want deal notifications (no specific niche identified)

Pain level: low

Price-drop alerts solve a real but weak pain — most shoppers either don't care about incremental savings, use existing free tools (Honey, Keepa), or check prices manually. The problem is solved, not underserved.

Market size

TAM: ~$10B affiliate marketing TAM globally, but price-alert segment is <5% of that (~$500M). Most value flows to retailers and affiliate networks, not tools.

Year-1 SOM: $0–50K year 1 as a solo founder. Affiliate commissions are thin (0.5–3%), require massive traffic to monetize, and you'd need 10K+ active users just to hit $500/month.

Competitors

Moat

None. Feature parity is easy to replicate, affiliate networks are commoditized, and network effects are absent. The only moat would be a proprietary data source (e.g., exclusive retailer partnership) or a narrow niche (e.g., luxury watches only), neither of which is in the idea.

5 actions for this week

  1. Spend 2 hours researching Honey's and Rakuten's affiliate payouts, user acquisition cost, and retention curves on public sources and founder interviews — understand the unit economics you'd need to survive.
  2. Install and use Honey, CamelCamelCamel, and 3 other price-alert extensions for a week; document what they do, what breaks, and where the UX is bad — you need a wedge.
  3. Cold-email 5 affiliate network managers (Amazon, Rakuten, ShareASale) asking: would you prioritize a new price-alert extension over Honey? Document responses honestly.
  4. If you find a wedge (e.g., luxury goods, niche category, or a retailer with poor affiliate coverage), validate it with 10 cold outreach calls to that niche buyer — does the pain justify switching tools?
  5. If no wedge emerges by end of week, kill this and move to the next idea; this is a feature, not a business, and you'd be grinding on affiliate commissions for 12+ months with no path to $10K MRR.

Kill criteria

If 0 of 5 affiliate network managers express interest in prioritizing your extension over incumbents, OR if you cannot identify a specific niche (product category, geography, or user cohort) where existing tools have <50% market penetration, kill this by end of week. Do not build a generic price-drop extension; the game is over.
