The page loads like it's carrying luggage
Apps you tried once still load scripts on every page. Photos ship at camera size. On a phone over 4G, shoppers wait, and plenty leave before the product appears.
Shopify speed and conversion studio for DTC brands
Your Shopify store already has the traffic. We make more of it buy.
We find where your store leaks sales on mobile, then fix it in ten days: faster pages, product pages that answer every question, and a cart that lifts the order. Fixed price. Speed guaranteed.

Feel what a slow store costs you
Press run. Both phones open the same product page on mobile data. One still carries every app it ever installed and camera-size photos. The other has been through a Sprint.
A 0.1 second faster mobile site lifted retail conversions by 8.4% and average order value by 9.2%.

Three places your store loses sales
The product page makes buyers hunt
Price, reviews, shipping and returns sit in different corners of the page, and add to cart hides below the fold. Every extra scroll is a moment for doubt.
The cart lets the order shrink
A shopper three dollars short of free shipping never hears about it. Relevant add-ons go unoffered. Each gap is small, and together they set your average order value.
The Conversion Sprint: ten days, one fixed price, on a copy of your theme
Your live store stays exactly as it is until you approve the preview. You get a three-line update every day: what's done, what's next, and anything we need from you.
- Day 1
Audit and fix list
Every app, script, image and template reviewed. You get the prioritised list the same day.
- Days 2–4
Speed
Unused app code removed, scripts deferred, images resized and served in modern formats.
- Days 5–7
Product page
Buy box above the fold on phones, reviews and shipping beside the button, a short FAQ, sticky add to cart.
- Day 8
Cart and tracking
Free-shipping progress, one relevant add-on, and GA4 and Meta purchase events checked end to end.
- Day 9
Your review
Tested on real iPhones and Androids, then a preview link for you to click through.
- Day 10
Live, with proof
Published after your OK, with a before and after report of every change and score.
If your mobile speed score doesn't rise by at least 20 points, you get every dollar back.
Measured with Google PageSpeed Insights on your main product page, the median of three runs, before and after. We record the baseline with you at kickoff.

You work with the person doing the work
I'm Harshit, founder of Brainycorn. I run ads, design storefronts and write the code in Shopify, React and Hydrogen. That lets me follow a shopper from the ad they tap to the checkout they finish, and fix the step where they drop off. Every message you send reaches me, and I'm the one changing your theme.
Questions founders ask before a Sprint
Will you touch my live store?
Only when you say so. All work happens on a duplicate theme. You review a preview link on day 9, and we publish on day 10 after your written OK. Your old theme stays saved as a backup.
Do I need a new theme?
Usually not. Most of the speed and conversion gains come from fixing the theme you already have: removing leftover app code, resizing images and rebuilding the product page layout.
We already have a developer. Why bring you in?
Developers build what's on the roadmap. A Sprint looks only at what stops shoppers from buying. If you prefer, we hand your developer the exact fix list from the teardown.
How is the speed guarantee measured?
Google PageSpeed Insights, mobile, on the main product page you choose. We take the median of three runs at kickoff and again after launch. If the score rises by less than 20 points, we refund the Sprint in full.
What do you need from me?
Collaborator access to Shopify, which you approve in your admin, viewer access to GA4, and 20 minutes for a kickoff call. We never ask for your password.
We're in the US. How do calls work?
Calls happen in US mornings, Eastern and Pacific. Your daily update arrives in your inbox before your working day starts.
