The product was never the bottleneck. Reach is.

Five years of selling online taught us that good products rarely fail on quality — they fail on reach. We're a team of PhD mathematicians who read demand straight from Google search data, find where it's heating up, and aim a large-scale ad chain at exactly those hotspots.

The insight

Good products get stuck in the neck of the bottle.

In five years of e-commerce we kept seeing the same thing: shelves full of genuinely good products that almost nobody found. The product was never the problem — reaching enough people was. So we treat advertising as a math problem: where is the demand, when does it peak, and how do we reach it at scale?

How the partnership works

From product sheet to sales curve in four steps.

  1. STEP 01

    You send us the product

    An ASIN, a listing or just a spec sheet. We pull price, margin, category and the whole keyword universe around it.

    • Listing or product sheet
    • Cost, price and stock
    • Any past ad data you have

  2. STEP 02

    We map demand hotspots

    We pull search interest directly from Google for every keyword around your product, then run it through seasonality decomposition and z-score detection. The output: which hours, days and regions are running hotter than normal.

    • Hour × weekday × region demand grid
    • Seasonal peaks separated from noise
    • Hotspots flagged at z > 2
    Demand index · weekday × hour · sample dataσ-flagged
    0 100 hotspot · z > 2
  3. STEP 03

    We fire the ad chain

    Hotspots become targeting. Your product goes out across search, short video, feed, stories and retargeting at the same time — timed to the hours demand peaks, with budget moved every day toward what converts.

    • 5 channels running in parallel
    • Creatives tuned to each hotspot
    • Daily budget reallocation

  4. STEP 04

    Your sales go up

    More buyers land on your listing at the moment they're already searching. You get one weekly report: units, ad spend and return — no black box.

    • Weekly units, spend and return
    • Which hotspot drove which sale
    • Next month's demand forecast

What buyers actually see

Your product, everywhere the hotspot scrolls.

One product, many formats, launched together. These mockups show how the same item is packaged for each placement — your real brand and creatives replace “yourbrand”.

Why a math team

Advertising, treated as an estimation problem.

Most ad agencies guess, then report. We estimate, test and update. Three ideas do most of the work.

yt = Tt + St + εt

Seasonality, separated

Search interest is split into trend, weekly and yearly seasonality, and noise — so budget lands on real peaks, not on last week's random spike.

z = (x − μ) ⁄ σ

Hotspots, not hunches

An hour, day or region only counts as a hotspot when its demand sits more than two standard deviations above its own baseline.

θk ~ Beta(αk, βk)

Budget that learns

Each channel's conversion rate is a probability distribution that updates with every sale. Spend shifts toward what converts, every day.

5 years of e-commerce

Sourcing, listing, pricing and moving real inventory — we know what a sale costs because we've paid for them.

The team

Sellers who think in distributions.

We studied mathematics at MIPT — the Moscow Institute of Physics and Technology, then moved to the US for our PhDs. Along the way we spent five years selling online. Put the two together and you get a partner who reads your market like a dataset and sells like a seasoned merchant.
