Prelude, a Paris startup, has raised $20 million in Series A funding led by 20VC

Prelude’s platform uses telecom data, device intelligence, network signals, and behavioural patterns to build a continuous trust profile for each user

Over the past year, the company has grown its revenue and customer base by six times. Prelude now handles user verification for one of the world’s largest social networks.

When Matias Berny and Quentin Le Bras worked on SMS verification at Zenly, they discovered that up to 30% of the budget was lost to fraud from fake intermediaries. Older providers either missed this problem or had no reason to fix it.

After Snap bought Zenly and later shut it down in 2023, the duo started Prelude to help other companies avoid similar losses. Its platform uses telecom data, device intelligence, network signals, and behavioural patterns to build a continuous trust profile for each user.
