Because tipster brands sell faces. Engineer projects sell evidence. The math doesn't care who I am — and you shouldn't either. Verify the public log instead.

Is this a one-person operation?

The model, pipeline, and code: yes, one engineer. Customer support and infra: managed via tooling and automation. The fewer people, the faster the iteration on the model.

What's your tennis betting record?

Every single graded prediction since Feb 13, 2026 is published at tipero.app/track-record. All-time ROI and bankroll update live from the same database the engine writes to — no curation, no hidden losses.

What happens if I sign up and lose?

Annual subscribers get 30 days money-back, no questions. The promise is the policy, not the picks — variance is part of betting, and the long log proves the long edge.

Built by an engineer, not a tipster

No face. No "guaranteed wins." Just a quant who got tired of tipster bullshit and built a tennis model — every pick logged publicly since Feb 2026.

I built TIPERO for myself first. After three years of paying tipster subscriptions and watching the same selection-bias playbook repeat, I wrote my own ratings engine, calibration loop, and bet selector. It started printing. Then a friend asked for the picks. Then his friend did. That's why this exists.

Why anonymous

First principle

Tipster brands sell faces because they have to. There's nothing to verify, so the personality is the product. Engineer projects sell evidence — and the moment you put a face on it, the conversation drifts away from the math.

So I keep the face out of it. Verify the public log instead. If the numbers are bad, walk away. If they're good, the wrapper doesn't matter.

What I actually built

The short version, in plain language:

The model

Surface-specific Elo ratings (separate for ATP/WTA, separate for hard/clay/grass), refreshed daily from every recent match. Layered on top: form (last-5 weighted), head-to-head, calibration against market-implied probabilities, and a learned correction term from 38k historical matches.

Every match the model expects has an explicit win probability — and that probability is calibrated so 60% actually means ≈60% over the long run. That's the part most tipsters skip.

The bet selector

Just because the model has an opinion doesn't mean we bet. The selector applies an expected-value gate, a Kelly-fraction stake (capped to keep variance survivable), a tier system (Core / Value / Long / Ultra by odds band), and surface-specific filters that have proven to reduce drawdown.

Average week: model rates ~300 matches, selector keeps ~12-20 bets. The rest stays untouched.

The infra

One pipeline runs every night. Reads yesterday's results, grades every prediction, retrains the calibration layer, fetches tomorrow's matches with live odds, scores them, applies the selector, publishes to tipero.app. Total runtime ~65 min. Zero hands on the wheel.

Pick gets graded the next day automatically. Track record is read live from the same database the engine writes to. There is no manual curation, no "we only show the wins" filter, no delete-bad-bets switch.

What TIPERO isn't

Not a tipster service. No "lock of the day," no influencer voice, no telegram pump-and-dump.
Not a sure thing. Bad days exist. Losing weeks exist. The 30-day rolling ROI sometimes goes negative. The long edge holds because the model is calibrated — not because every pick prints.
Not for parlay degenerates. The math doesn't work on 10-leg accumulators. Singles, occasional doubles, units measured in 1% of bankroll. Boring on purpose.
Not pretending to be neutral. The site sells subscriptions. The picks are real, the log is public, but I'm not your friend — I'm the operator. Read accordingly.
