Manpreet Singh

Manpreet Singh is the founder of Proscube, an ecommerce growth studio that builds Shopify and headless storefronts for DTC brands and then tries to prove the work moved something.

He leads the studio's engineering directly — Shopify and Shopify Plus builds, headless storefronts on Next.js and the Storefront API, conversion work, and the integrations that sit behind both. He works with founders without an account-manager layer in between, which is a deliberate constraint on how many engagements the studio takes at once rather than a growth strategy.

Most of his writing is about the gap between what ecommerce advice claims and what the numbers support. The studio publishes its split tests with confidence intervals attached, including the ones that did not settle — the Pawpeye test on this site is published with the plain statement that eleven add-to-cart events against six is not a result, however good the percentage looks. That standard is unusual enough in the category to be worth stating.

He also turns work down fairly often. A brand whose traffic cannot settle a split test does not need a CRO retainer, a store shipping daily merchandising changes is usually better served hiring than retaining an agency, and a problem that a spreadsheet solves should stay a spreadsheet. Saying so costs the studio engagements and makes the ones it takes easier to deliver.
