About 5sec.io
Who is behind 5sec.io?
I’m Anthony Roose. I built 5sec.io because I kept seeing companies lose visitors before those visitors understood the offer. The same problem came back every time: plenty of visitors on the website, but few or no conversions and leads.
For more than 20 years, I have worked as a product and marketing strategist. I design products and services that work for the people who use them.
In recent years I widened my focus to digital marketing. I saw the same thing again and again: even the best product does not sell without a clear message. Visitors leave before they understand why it matters to them.
Most teams never see that moment. Analytics show the bounce, not the reason. And you know your own product too well to read your homepage like a stranger.
So I built 5sec.io. The free test runs fully on AI. It reads your page the way a first-time visitor does and tells you what came across in five seconds and what did not. When you want the full picture, our two audits go through your whole site, check by check. They combine AI with our review team, and every finding comes with a fix.
I lead the review team myself. A conversion expert checks every audit finding before the report reaches you, and I stand behind every word.
