The Bonus Doctor — iGaming Analytics: Bonus ROI, Player Value, Retention

Measured, not estimated

Three numbers from real engagements.

-96% promo cost on the abuse tier Net revenue per player flipped positive in 13 days.

15-25× return on mid-tier VIP rakeback The whales returned 1-4x. Sometimes negative.

4.5% → 71% of players drove 71% of deposits And you could see who they were by day three.

Anonymised. Each measured against a control group or a baseline, with its conditions attached.

The work · anonymised, numbers real

Four engagements. Four verdicts.

Sweeps · Bonus economics

The whales didn't need the subsidy

Four mechanics, no read on any of them.
Rakeback: 15-25x mid-tier, 1-4x on whales.
Daily bonus cut to a fifth. Cost -75-85%. Conversion untouched.
The worst abuse tier lost money on every promo.

Whale subsidy capped, mid-tier fed. Promos off for the abuse tier: cost -96%, net revenue positive in 13 days.

Sweeps · Early life

Day 3 tells you who matters

62% bounce after one session.
4.5% carry 71% of all deposits.
Both visible by day three.
Bonus spend was treating them identically.

A day-3 score now routes early spend - generosity follows the players who'll still be there in 30 days.

Multi-brand · Bonus & CRM

Would it have happened anyway?

Four brands, three markets, no shared read.
Where the money goes - by tier, product, purpose.
What it buys - against control groups.
A +62% revenue uplift came with +30% bonus cost.

Per-programme verdicts: keep, cap, redesign or kill - including the underwater ones nobody had spotted.

Sportsbook · Retention

You win the bet, not the player

Regulars stick: 52% still active a year in.
But only 4.4% of new depositors reach VIP.
Reactivated players churn at 44%.
Top 5% carry 63% of revenue - unprotected.

A named lapsed-VIP pilot, an early-activation journey, a daily top-5% watchlist. Retention as a programme, not a report.

What we do

Three ways operators use us.

Bonuses are where we start, not where we stop. The same discipline runs across retention, acquisition, VIP and player value.

01 · Insights

The read, with a verdict

Fixed scope, written readout, executive walk-through. Findings and actions - not another dashboard.

Bonus efficiency Player value & VIP Retention & reactivation Acquisition quality Campaign incrementality Redemption risk

02 · Reporting builds

Raw data to trusted numbers

For sweeps operators growing faster than their reporting. Built on your warehouse, reconciled before anyone trusts it.

Curated aggregates GC / SC wallet model Daily scorecard Data-quality alerts Value segmentation Documented handover

03 · Bonus engines

For before there's data

Launching, entering a market, adding a vertical. The engine that creates the data doesn't exist yet - we design it.

How it runs

Four phases. Every engagement.

Fast because it's pre-solved - the value models, efficiency frameworks and detection logic already exist. Not a discount.

Map & QA

What your data can actually support. This step has caught revenue-inflating bugs before launch.

Build the base

Value models, segmentation, aggregates. In your warehouse, documented, reusable.

The readout

Every finding paired with an action. Numbers you can defend upward.

Test & act

Pilots with controls and kill criteria. Done means running without me.

Fixed fee, scoped on a free 30-minute call. No day rates. No prices on websites.

Who you're dealing with

Angeliki Kiakotou, PhD

Founder, The Bonus Doctor.

Thirteen years operator-side, including Entain. Multiple operators, often in parallel - UK, regulated EU, North America, .com and LatAm. Casino and sport, RMG and sweepstakes. What I sell is the pattern recognition that vantage point produces.

Before iGaming: a doctorate in theoretical astrophysics. The physics doesn't transfer. The discipline of separating signal from noise does.

Start from the decision, not the data. Build things that keep answering. Then say what the numbers say - the whales who didn't need the subsidy, the campaigns that weren't incremental, the bonus that was buying nothing.

A small senior team behind me on the technical build - analysts who have lived inside this industry. I front every engagement and QA everything that ships.

One rule doesn't bend: the analysis is sacred. If the data doesn't support it, it doesn't ship - whoever it disappoints.

The AI vertical
