The referral bonus barometers
Who pays the most for a new customer? Sector by sector, our barometers rank referral bonuses and welcome offers using a common methodology: amounts in euros only, the maximum bonus accessible to a new customer, manual verification of every offer, and automatic recalculation whenever a bonus changes. An editorial summary is published every quarter.
Life insurance & savings
Online brokers, robo-advisors and savings accounts: the sector that pays new customers the most.
Banks & neobanks
Referral bonuses and welcome offers on current accounts, with online banks in the lead.
Stock brokers
Cash, free shares or reimbursed fees when opening a brokerage account.
Crypto platforms
Sign-up bonuses from crypto exchanges and apps, in two separate € and $ rankings.
Real-estate crowdfunding
Welcome bonuses from real-estate crowdfunding platforms — capital at risk.
Energy & telecoms
Electricity, gas and heating-oil suppliers, plus the cash offers from broadband & mobile providers.
Cashback sites
The most accessible bonuses: no deposit required, just a sign-up and a first purchase.
Meal kits & delivery
First-order discounts from meal-kit boxes, delivery platforms and online groceries.
A common methodology
Every barometer applies the same rules: only bonuses expressed in euros are ranked (the crypto barometer adds a dollar section, without conversion); the amount retained is the maximum accessible to a new customer, conditions included; non-monetary perks — free subscription months, percentage discounts, points — are excluded. Every offer is manually verified and displays its last verification date. The figures are freely reusable with a link to the relevant barometer as the source.
