Two projects this quarter
I find the decision first. Then build the smallest thing that settles it.
My rates are high and I don't pad hours. Fixed price, so my speed is my problem and not your invoice — you're paying for knowing where to look, not for the time it takes me to look.
Book me
Most days are closed. I take two projects a quarter and the open slots are what's genuinely left.
Flagship
Today's data agents have senior execution and junior judgment. Great SQL, guessed definition. The guardrails are the product.

Or book fifteen minutes. No brief, no RFP.
What changes depending on the answer? We sketch your metric tree. If there's no decision under it, I say so and you've spent nothing.
Fixed. If the job is bigger than the package, you hear it now.
You get me, not a junior.
The number, what it costs you, what I'd do. Plus the keys.
What I fix
“GA4 and Meta disagree by 40% and I don't know which to believe.”
Trust“I can't tell which channel actually pays.”
Attribution“Our numbers live in eight tools and no two agree.”
Plumbing“Month-end reporting eats three days. Nobody reads it.”
Time“We know people churn. Not who, not when, not what it's worth.”
Money“Someone asked me for a dashboard and I can't work out what for.”
The real onePrices
Fixed fees, never hourly. An hourly rate pays me for being slow; a fixed fee pays me for being right. Half up front, one revision round.

The monthly pack, built once, updating itself.
When reporting eats days you don't have.
A standing half-day a week. Questions answered, numbers defended, and someone telling you when a request isn't worth doing.

Straight talk
Name who opens it on a Monday and what they change. Otherwise it's furniture.
It gets weaponised in a meeting within a month.
“Up 40%” is four out of ten often enough.
If it needs forty slides I haven't understood it yet.
Who I am
Gergana Tyaneva. I write the SQL and I present to the room — which is why the analysis survives the room.
2025 —
Analytics & Strategy Manager. Subscription pricing, trial-to-paid, retention, campaign measurement.
2018 — 2025
Product Analytics Manager. Seven years of product analytics and experimentation at marketplace scale.
2016 — 2017
Built the brand team's first KPI framework and the tracking behind it.
2014 — 2015
Measurement plans, KPI definition, tracking specs with dev teams.
Server-side GTM, mobile SDKs, consent plumbing.
Warehouse and pipelines that still agree at 6am.
Test design, honest sample size, calling flat results flat.
When a finding has to survive a board deck.
You hire me. I name anyone I bring in, what they cost, and you approve first. No account manager, no junior handover, nobody gets acquired out from under you — and no bench I have to keep busy, which is why the advice stays honest.
