Sixscape Communications
Sixscape Communications is a Singapore-based cybersecurity vendor specializing in Public Key Infrastructure (PKI) automation and post-quantum readiness. Founded in 2014 by cryptography veteran Lawrence Hughes, the company builds digital certificate-based products for secure email (S/MIME), password-less authentication, IoT device identity and unified communications. Its patented Identity Registration Protocol (IRP), assigned IANA port 4604, automates the request, issuance and management of X.509 certificates so enterprises can deploy trusted digital identities in seconds rather than weeks. Sixscape sells through a 100% partner-centric model spanning system integrators, resellers and certificate authorities, and positions its IDcentral platform for certificate lifecycle management and cryptographic posture management in a market bracing for shorter TLS certificate lifespans and the migration to quantum-safe algorithms.
Omnisient - Collaborative Consumer Intelligence
Omnisient is a privacy-preserving data collaboration company that lets banks, insurers, retailers and consumer brands analyze their first-party data together without ever sharing or exposing it. Using privacy enhancing technologies, US-patented Crypto-IDs and AI-powered data clean rooms, the platform matches mutual customers across datasets so lenders can score credit-invisible and thin-file consumers using alternative behavioral data - all while personal information never leaves the owner's environment. Founded in Cape Town and now expanding into the United States, the company protects hundreds of millions of consumer records for more than 100 enterprises.

Fabric Cryptography is a San Francisco hardware startup building the Verifiable Processing Unit (VPU) - a fully programmable custom-silicon chip with an instruction set designed specifically for advanced cryptography. Founded in 2021 by Michael Gao, Tina Ju, and Sagar Reddy, Fabric aims to do for cryptography what Nvidia did for AI: dramatically accelerate workloads like zero-knowledge proofs, fully homomorphic encryption, and multi-party computation compared with CPUs, GPUs, and fixed-function accelerators. The company has raised $39M total, including a $33M Series A in August 2024 co-led by Blockchain Capital and 1kx.
Matthew Cohen
Matthew Cohen is the co-founder and chief executive of Provable Markets, a New York fintech running Aurora, an SEC-registered Alternative Trading System for securities lending. After 15 years trading equity finance at Bank of America Merrill Lynch, Jefferies, and Nomura, Cohen partnered with cryptographer Thomer Gil in 2020 to apply secure multi-party computation to a market that had run for decades on phone calls, spreadsheets, and information leakage. In 2022 Provable ran the first securities lending transaction cleared through DTCC's SFT service. In May 2024 the company raised an $8M Series A led by Dialectic Capital Management.
Shane Curran
Shane Curran is the founder and CEO of Evervault, an encryption infrastructure company he started in 2018 after dropping out of University College Dublin three days into a business and law degree. A year earlier, at 16, he had won the BT Young Scientist and Technology Exhibition with a post-quantum encrypted storage project called qCrypt. Evervault sells developer-facing tools that keep sensitive data - card numbers, health records, keys - encrypted while still being processed, running inside AWS Nitro Enclaves. The company has raised $46 million from Sequoia, Kleiner Perkins, Index Ventures and Ribbit Capital, most recently a $25M Series B in March 2026.
Alpen Labs
Alpen Labs is a Bitcoin infrastructure company building Strata, a zero-knowledge (ZK) validity rollup and bridge that lets people borrow, earn, and transact in dollars directly on Bitcoin - without wrapped tokens or custodians. Founded in 2022 by a team of MIT alumni, the company uses ZK cryptography to bring programmable smart contracts and DeFi-style financial products to Bitcoin while preserving its security and decentralization.
Succinct
Succinct is a San Francisco cryptography company building SP1, an open-source zero-knowledge virtual machine that lets developers prove the correct execution of any Rust program, and the Succinct Prover Network - a decentralized marketplace where independent provers compete to generate ZK proofs for rollups, bridges and onchain applications.
Simanta Gautam
Simanta Gautam is the co-founder and CEO of Alpen Labs, a startup building zero-knowledge infrastructure to make Bitcoin scalable, private, and programmable. An MIT-trained engineer who earlier founded the airport-security computer-vision company Synapse Technology (acquired by Palantir, where he became AI Lead), he now leads a team turning Bitcoin's intentionally limited base layer into rails for global money. The mission traces to a personal detail: founders with roots in Nepal, where roughly a quarter of GDP arrives as remittances, saw firsthand how much money is lost to middlemen.
Umaimah Khan
Umaimah Khan is the co-founder and CEO of Opal Security, a San Francisco identity security company building the controls that decide who - and increasingly what - can access an organization's systems. A homeschooled math kid who entered MIT at 16 and fell for cryptography, she did research embedded with government agencies including DARPA, then engineered infrastructure and security at two startups that became unicorns. She founded Opal in 2020 to treat authorization as the hard technical problem she believes it is, and has raised roughly $32M, including a $22M Series B in December 2023. Opal's customers include Cloudflare, Figma, Databricks, Scale AI, Grammarly and Perplexity.
Alon Webman
Alon Webman is the co-founder and CEO of Chain Reaction, an Israeli semiconductor company building purpose-built chips for encrypted computation, Bitcoin mining, and privacy-preserving AI. Before Chain Reaction, he co-founded Mellanox Technologies in 1999 and spent nearly two decades there, rising to VP-level roles before NVIDIA acquired Mellanox for $7 billion in 2020. A Technion graduate, Webman is now betting his second act on making fully homomorphic encryption practical at scale - a technology that would let clouds compute on data they can never see.

He also designed the Noise Protocol Framework, a foundational cryptographic framework deployed in WireGuard, WhatsApp's client-server layer, and the Lightning Network. A 2017 Levchin Prize winner, Perrin works as an independent consultant on quantum readiness and cryptographic systems design.
Vitalik Buterin
Vitalik Buterin is the Russian-Canadian programmer who, at age 19, wrote the Ethereum whitepaper and changed what a blockchain could be. He turned a programmable ledger into an idea engine - smart contracts, DeFi, NFTs, DAOs - and then spent years fighting to keep it decentralized. He travels with a single suitcase, posts thousand-word blog essays at 2am, and once cried over a World of Warcraft nerf that indirectly launched a $200B ecosystem.
