About
We believe your data
should be yours.
NoSheet exists to give teams a single platform that cleans, protects, and activates their data — without compromising on security or usability.
Dirty data costs businesses billions
Teams copy data between five different tools. PII sits unencrypted in shared Google Sheets. Campaigns go out with 30% bounce rates because nobody cleaned the phone numbers. Compliance audits trigger panic because there's no audit trail.
No single platform could clean, protect, and activate data — until now.
Cost of bad data annually
IBM estimates poor data quality costs the US economy $3.1 trillion per year.
Average SMS bounce rate
Campaigns sent with unvalidated phone numbers waste budget and kill deliverability.
Tools to manage one dataset
Teams juggle Google Sheets, Excel, Zapier, Mailchimp, and custom scripts just to clean and send.
Platforms that do all three
No existing tool cleans, encrypts, and activates data in a single workflow.
Our Approach
Three pillars. One platform.
Every decision we make is guided by these principles.
AI-First
Let AI handle the tedium so your team can focus on strategy.
- Natural language data cleaning
- Smart anomaly detection
- Auto-formatting and deduplication
- AI-generated reports and insights
Security-First
H33 post-quantum encryption is baked in, not bolted on.
- Cell-level FHE encryption on PII
- DLP scanning and quarantine
- 12 ISMS controls in Rust
- Tamper-proof hash-chain audit trail
Developer-First
Your data goes where you need it. API keys, webhooks, Zapier.
- REST API with full CRUD
- HMAC-signed webhooks
- Zapier and Mailchimp integrations
- CSV, XLSX, and PDF export
Backed by H33 Post-Quantum Cryptography
NoSheet's encryption layer is powered by H33, a post-quantum cryptography engine benchmarked at over 2 million authentications per second on production hardware.
- BFV Fully Homomorphic Encryption (FHE) — compute on encrypted data
- Dilithium post-quantum digital signatures for attestation
- Benchmarked at 2,172,518 auth/sec sustained on Graviton4
- 38.5 microseconds per authentication — faster than a blink
- Post-quantum safe: resistant to both classical and quantum attacks

Open Source Commitment
We believe the best way to earn trust is to be transparent about what we build and how we price it.
