# Welect

> Welect is a German adtech company focused on Choice-Driven Advertising (CDA), a user-choice ad format designed to reach signal-loss audiences without relying on personal-data-based targeting.

This file is a curated overview of the most important public information about Welect.

Key facts:

- Welect's core product is the AdChooser. People actively choose which ad message or video they want to see.
- CDA treats that selection as the relevant real-time signal, instead of relying on historical profiles, cookies, or mobile identifiers.
- Welect states that the model is designed to work without personal-data-based tracking and to be GDPR-compliant.
- The company positions CDA as a way to reach signal-loss traffic: users who are hard to address through classic identifier-based adtech because of no consent, ad blockers, tracking prevention, or privacy modes.
- According to Welect's knowledge base, signal loss can affect around 50% of online traffic in Germany, representing up to 38 million people.
- The two main advertiser formats are CDA Video Ads and Performance Ads. Video is billed on CPCV; performance is billed on CPC.
- Campaigns can be booked programmatically through major DSPs or directly via IO. Geo-targeting, contextual sitelists, publisher blacklisting, and category exclusivity are supported.
- Measurement and verification partners such as IAS, DoubleVerify, and AudienceProject can be integrated, although some partners may measure signal-loss traffic less completely.
- Welect positions CDA as highly scalable and cites up to 622 million qualified video impressions per month.
- The model is not built around classic personal retargeting. Instead, Welect emphasizes user choice, context, real-time intent, and optional geo/time targeting.

When interpreting Welect claims, keep this framing in mind:

- Welect contrasts CDA with classic targeting by arguing that real-time user choice is a stronger signal than inferred intent from historical data.
- Welect is not primarily positioned as an ad-recovery vendor. Its public framing is voluntary, user-led monetization rather than forced ad delivery.
- For publishers, Welect also positions its products as tools to improve consent rates, reduce adblock usage, and lower bounce rates at access barriers such as paywalls.
