Most of your visitors leave empty-handed, and you can’t see why. Echo can. It finds what’s stopping them, builds the A/B tests that fix it, and only keeps what actually makes you more.

Don’t take our word for it. Below, shoppers split at random between two identical pages. Watch what a typical dashboard makes of it.
Every dot is a shopper, split at random between two identical pages. The 3% who buy light up and pool. Put your cursor in the stream.
Dashboard · day 1
Doors open…
You can’t tell a buyer from a browser until they decide. Neither can the dashboard tell luck from a better page.
You need a developer.
Every test is a ticket. Every ticket waits behind the next launch. Six weeks later you’ve tested one headline and lost interest.
You need a statistician.
Plenty of dashboards paint a big green ‘winner’ the moment a test crosses p < 0.05. Check every day and identical pages ‘win’ again and again. You just watched it.6
Most ideas don’t work.
Even at Microsoft, only about a third of tested ideas improved what they were meant to.4 Your gut isn’t better than Microsoft’s. Test more, test cheap, test honestly.
Echo is the developer and the statistician. You’re the boss.
Meet Echo.
Your new conversion specialist. It builds your tests, checks them, guards them and ships what wins. Doesn’t sleep, doesn’t bill by the hour, and never calls a winner on day three. Point at anything below and it’ll tell you about it.

Do the math. It’s your money.
Drag the sliders to match your store. Tiny lifts on traffic you already pay for turn into numbers that make you a bit sick.
Your store today
5 orders and $50 a month
Extra revenue a year
$6
That’s 0 more orders a month. Getting them from ads instead means buying about 10 more visitors, every month.
How it adds up over a year
Orders a month: 5 now, 5 with the lift
Each dot is an order a month. Green is the lift.
Arithmetic, not a forecast. Most tested ideas don’t win4, which is exactly why each one gets tested before it’s kept.
Everything in Echo. Go on, touch it.
Thirteen tools a CRO consultant would invoice you for, in one place. Pick one and play.
Store scan
A real phone and a real laptop open your store, close the popups, and measure what costs you sales.
Watch the real scanner open our test store, Fieldwork Supply Co., on a phone and a laptop. It closes the popups, measures where the buy button sits, and writes up what’s costing sales.
Three steps. No excuses.
Setup takes about as long as reading this section.
Paste one line.
Into your store’s <head>. Shopify, Woo, Webflow, whatever. That’s the last time you need a developer.
Say yes or no.
Echo lines up tests with the reasoning written out. Approve, tweak or bin them. Nothing runs without you.
Keep the winners.
Each test runs its planned window. Winners ship in one click. Losers get filed so nobody tries them again.
Fast. Private. Boring to your lawyer.
It lives on every page of your store, so it had better be tiny, polite and on a short leash.

A note from the founder
I got tired of watching good stores bleed.
I do conversion optimization for online stores. It’s the same story nearly every time: a good product, decent traffic, and a site quietly losing sales in the same five places.
The fixes aren’t secret. Testing them properly is the hard part. The serious tools are built for companies with analysts and developers. Everyone else gets an agency quote, a long wait, or a tool that crowns a “winner” after two days of noise.
So I built the tool I wanted. It does the CRO grunt work, tests honestly, and leaves every decision with you.
Echo is brand new. There are no case studies on this page because there aren’t any yet, and I’m not going to make them up. Join now and you get early access and a direct line to me.
The founder of Echo
One line of code. Wherever you sell.
No app. No new theme. No replatforming. Pick your platform and see exactly where it goes.
Shopify: Online Store → Themes → Edit code → layout/theme.liquid. Paste it right after <head>.
<script src="…/echo.js" data-site="YOUR_KEY"></script>
Questions. Straight answers.
Brand new. That’s why there are no case studies or customer logos here: there aren’t any yet, and we’re not going to invent them. Join now and you work directly with the person who built it.
Quit guessing.
Start knowing.
Paste your URL. In about a minute you’ll know where your store loses sales. Worst case, it’s perfect. (It isn’t.)
