Our mission at Discreet Labs is to make privacy more programmable through adoption of applied cryptography, and decentralized blockchain technology.
 
Discreet Labs is the developer of Findora, a public blockchain with programmable privacy. The original research team behind Findora also invented Bulletproofs, a type of zero-knowledge proofs that have been widely used across different blockchains such as Monero, Mimblewimble, and Grin. Discreet Labs has implemented Bulletproofs on Findora to support confidential transactions, and private asset issuance. The company is also working on additional zero-knowledge proofs to support confidential smart contracts for more programmable privacy.
 
Discreet Labs is backed by Polychain and Powerscale Capital, and is partnered with dozens of companies and organizations including Tencent, BSN, MetisDAO, Taxa, Bank of Asia, Travel USA Express, MoneyMoov, IOTPay, YouWorld, Citcon, and Bayes.
 
We have offices in Palo Alto, CA and Beijing, China, plus we have the platform tools and benefits to support you in your remote work environment.
