Questions & Answers

As answered by people managing Codility and WhatNotSell.

How would you describe the primary audience of your product?

WhatNotSell's answer:

Deal hunters and smart shoppers who are tired of fake discounts and want a single trusted place to find genuinely good deals. Secondary: content creators and businesses who need structured deal data via our API plans.

What makes your product unique?

WhatNotSell's answer:

Every deal gets an AI score from 0–100 based on discount depth, price, retailer trust, and community votes — so instead of scrolling through hundreds of listings, you instantly see which deals are genuinely worth it. We combine 9,500+ deals across 36 categories with 100 expert buying guides, so you can research what to buy and find the best price in one place.

Why should a person choose your product over its competitors?

WhatNotSell's answer:

Traditional deal sites either rely on community voting alone (slow to surface deals) or pure editorial curation (limited volume). WhatNotSell uses AI scoring to evaluate every deal automatically at scale, filtering out fake discounts and inflated "original prices" that plague deal aggregators. Plus, plain-English price alerts and a free forever plan — no extension installs, no data selling.

What's the story behind your product?

WhatNotSell's answer:

WhatNotSell started from a simple frustration: deal sites are full of noise — inflated original prices, expired links, and "deals" that aren't deals. We built an AI scoring engine that evaluates every deal objectively, then layered in expert buying guides and price alerts. The goal: tell you what's actually worth buying, and what's not — hence the name.

Which are the primary technologies used for building your product?

WhatNotSell's answer:

Next.js, TypeScript, Tailwind CSS, Supabase (PostgreSQL), and Vercel, with AI-powered deal scoring and categorization.

Who are some of the biggest customers of your product?

WhatNotSell's answer:

WhatNotSell is a free consumer platform, so our "customers" are everyday shoppers rather than enterprise clients. We're an early-stage product growing our user base, focused on helping individual shoppers verify deals and avoid overpaying.
