We built a verification engine because coupon sites are broken.
SimplyCodes exists for one reason: most coupon codes on the internet don't work, and nobody was willing to fix it. So we built a system that tests every code before you see it.
The coupon industry has a trust problem.
Coupon sites make money from clicks, not accuracy. They scrape codes from every source they can find — expired emails, old forum posts, social media leaks — and list them all. More codes means more page views means more ad revenue. Whether the codes work is irrelevant to their business model.
The result is an industry where 40-60% of listed codes are dead on arrival. Consumers waste time trying code after code. Merchants get flooded with invalid code attempts. And the coupon sites profit regardless.
We decided to build a different kind of system. One where every code is tested before it's shown. One where accuracy is the product, not an afterthought. One where we show you the evidence behind every verdict.
Started building commerce data infrastructure. Bootstrapped from day one. No venture capital.
Browser extension and website go live. Built on the premise that verification should come before display.
Crossed one billion dollars in annual gross merchandise value processed through verified codes.
Automated testing, human verification network, and fleet signal all running. 10,000+ verifiers active.
SimplyCodes becomes a Product.ai company. 604K+ merchants in the database. The verification methodology expands beyond coupons into the full commerce truth layer.
SimplyCodes by the numbers
The principles behind how we build.
Competitors scrape codes from the internet and list everything they find. We test every code through a three-layer engine before showing it to anyone. A verified database of 1,000 codes beats an unverified list of 10,000.
Every verdict comes with a Proof Packet — a structured evidence chain documenting exactly how we reached our conclusion. Users, developers, and AI agents can inspect the evidence behind every claim we make.
When there are no working codes for a merchant, we say so. Most coupon sites pad results with expired junk to avoid showing an empty page. Our willingness to say "no" is what makes our "yes" trustworthy.
Privacy is not a feature we added. It's a constraint we designed around. We verify codes, not track users. The architecture makes surveillance impossible, not just unlikely.
We make money when our codes save you money. Our accuracy is our revenue engine. We never rank codes by commission rate or hide our economics. Affiliate relationships don't influence verdicts.
We're bootstrapped and profitable. No venture capital. No board. No pressure to compromise verification quality for growth metrics. We answer to our users, not investors.
The same methodology. A bigger mission.
SimplyCodes is a Product.ai company. Product.ai is building Axiomatic Intelligence for commerce — a system that determines truth through adversarial verification rather than averaging opinions or summarizing reviews.
The three-layer verification engine that tests coupon codes is the same methodology Product.ai applies to product claims across all of commerce. SimplyCodes is where that methodology was born and battle-tested at scale, processing over $1B in annual transaction value.
Product.ai is The Truth Layer for Commerce — and SimplyCodes is its proving ground.

Small team. Big verification engine.
SimplyCodes is built by a team of about 20 people in Santa Monica, California. We're engineers, data scientists, and product builders who believe commerce needs a verification layer.
We've been profitable since inception. We don't have a sales team, a marketing department, or a board of directors. We have builders who ship verification infrastructure.
If you're the kind of person who builds things that work rather than things that look good in a pitch deck, we might be a fit.
