Product Hunt • ProductHunt • Use case: Evaluating the product's potential to replace an existing proxy/redaction layer for AI agents.

WORKED

The idea that AI agents can reason on tokenized data without ever seeing the raw values is exactly what regulated industries need to adopt AI safely.

Product Hunt • ProductHunt • Use case: Building project finance models for renewable energy deals, handling sensitive data like tariff structures, counterparty financials, and tax equity terms.

WORKED

Astra intercepts before the prompt, agent works on tokens, real values resolve only at execution.

Product Hunt • ProductHunt • Use case: Building AI agents that handle regulated/sensitive data (e.g., patient SSN) without exposing the raw data to the LLM.
