Tier 1 — Self-Managed
ViperFish
Anonymous feedback your team controls.
Encrypted at rest. Threshold-protected — content unlocks only after a minimum number of submissions. Your admin holds the key. We cannot read your submissions.
Best for: Organizations that trust their own leadership and want a simple, secure anonymous feedback channel.
Tier 2 — Analyst-Managed
Cuttlefish
Submit to us. Receive a strategic assessment.
Employees submit feedback directly to Caisson analysts. We read every submission, identify themes and priority signals, and deliver a written strategic assessment to leadership. Your employees' identities are never shared — only our analysis.
Best for: Organizations that want expert interpretation, not a spreadsheet of raw responses.
Tier 3 — Zero Knowledge
SnailFish
Mathematical proof that nobody can identify who submitted what.
Zero-knowledge cryptographic proofs. The submission is verified without revealing the submitter. Not even Caisson can read the content or identify participants.
Best for: High-stakes environments, legal exposure, or situations where leadership itself is the subject of the feedback.
