Nalden Launches Boomerang For Privacy-Focused File Sharing

Nalden, WeTransfer co-founder, returns from retirement to launch Boomerang in late 2025 as a privacy-focused file-sharing service. The beta offers anonymous transfers up to 1GB free, paid tiers from €5 per month extending storage to 100GB and added features, and explicitly forbids using uploads for AI training. The move responds to Bending Spoons’s 2024 acquisition and changed WeTransfer terms permitting content use for model training.
Key Points
- 1Launches Boomerang offering anonymous transfers up to 1GB free, paid tiers scaling to 100GB
- 2Calls out WeTransfer’s post-2024 terms allowing AI training on uploads, framing it as trust breach
- 3Pressures practitioners to audit providers’ data-use policies and prefer services that avoid training on uploads
Scoring Rationale
Strong novelty and practical details driven by founder-led launch, limited by mostly sector-specific impact and competitive landscape.
