The same loop runs in the product every week, without the meetings.
take the tour
from an agency to an autopilot.
From 2023 acceleroi was one operator embedded in Shopify and SaaS teams: find the leak, build the change, test it on real shoppers, keep what wins. The loop was the same in every engagement. Only the judgment inside it was Denis's.
I ran the agency myself. Every client bought the same thing: the store gets better and they are not in the room. The meetings, the decks and the retainer were the price of that, not the product. So I wrote down how I decide: where revenue leaves a page, what to build first, when a test has earned a verdict, when to revert. acceleroi runs that on full autopilot, every week, in the store's own design. On 9 September 2026 a fresh store went from connected to a built, verified first change in thirteen minutes, with no one at a desk.
