The Houseparty Guy Got Burned Twice. Now He Wants You to Own the Group Chat.
Ben Rubin built Meerkat and Houseparty, watched both die, and decided the problem was ownership. Towns Labs is his answer: a messaging protocol where the community holds the keys, not the landlord.
Ockam Spent Years Making Networks Disappear. Then the Company Did Too.
The San Francisco startup raised $17.6 million to turn zero-trust plumbing into a developer primitive. Its sharpest lessons survive in open source - including the costly rewrite that finally made the idea click.
BlockSurvey
Most survey companies can read your answers. BlockSurvey built one that can't - end-to-end encrypted forms with an AI agent on top, run by two ex-fintech engineers who won a hackathon and never went back.

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.
Evervault
Evervault is a developer-first encryption platform that lets companies collect, store, process and forward highly sensitive data - especially payment card data - without ever handling it in plaintext. Founded in 2019 by Irish entrepreneur Shane Curran, the New York and Dublin based company pairs a dual-custody encryption model with products for card payments, secure enclaves and network proxying. It processes over $5 billion in transaction volume and generates more than 100 million encrypted tokens per month for customers including Ramp, Rippling and CarTrawler.
PreVeil
PreVeil is a Boston-based cybersecurity company, born out of research at MIT, that delivers end-to-end encrypted email and file sharing built on zero trust principles. Its data is never decrypted on any server, so it stays protected even if passwords are stolen, admin accounts are hijacked, or servers are breached. PreVeil has become the go-to compliance platform for defense contractors and other regulated industries needing to meet CMMC, NIST 800-171, ITAR, and DFARS requirements at a fraction of the cost of legacy alternatives.
