Waterhouse VC: Find a wagering edge

Summary

Tom Waterhouse profiles Bernard Marantelli, a punter-turned-entrepreneur who has industrialised wagering edge. From early bookmaking roots in Melbourne through algorithmic trading on Betfair and a finance stint, Marantelli moved from exploiting inefficiencies personally to building products and businesses that monetise and institutionalise advantage.

Key milestones covered include his Scoop6 successes, founding Colossus Bets (and inventing cash-out), building White Swan Data for large-scale modelling, the 2023 Texas lottery operation that returned US$57.8M in cash value, and his latest venture iBankroll, which packages bankroll-as-a-service to underwrite operator volatility and enable challenger brands to scale.

The piece highlights Marantelli’s loop: find inefficiencies, build systems to exploit them at scale, then offer those systems commercially to both bettors and operators.

Key Points

1. Marantelli combines deep market knowledge with engineering to scale wagering advantages across products and operators.
2. He pioneered industry-standard features: Colossus Bets introduced cash-out (branded ‘cash-in’) and syndicated pools to manage multi-leg jackpot risk.
3. White Swan Data runs proprietary models across many sports and has grown into a 150+ team split across quant, engineering and commercial functions.
4. The 2023 Texas lottery operation bought 99.3% of combinations, yielding a US$57.8M cash win — a hallmark of operational execution at scale.
5. iBankroll offers bankroll-as-a-service, giving challenger operators fixed expected GGR payments while iBankroll assumes variance — a product that could become standard for smaller brands.
6. Marantelli monetises both sides of the market: bettors (Colossus/White Swan) and operators (iBankroll), creating an ecosystem that raises competitive standards.

Context and relevance

This article matters to anyone tracking innovation in wagering, risk finance and betting product design. It shows how advancements in data, execution and financial engineering shift market structure: cash-out changed player behaviour industry-wide; iBankroll aims to change operator economics and risk management.

For investors, operators and product teams, Marantelli’s trajectory demonstrates how technical edge can be productised and scaled — turning sporadic wins into repeatable revenue streams and offering new services (like bankroll insurance) that change competitive dynamics.
