Rebecca Krauthamer

Chief Executive Officer & Co-Founder QuSecure

Last Reviewed: September 19, 2026

Executive Summary

Rebecca Krauthamer co-founded QuSecure in 2019 and runs it as chief executive. The company exists because of a structural problem in how organisations use encryption: cryptography underpins trust in every digital system, but it was never designed to be changed, and most organisations have little visibility into which algorithms, protocols and certificates they actually depend on. Quantum computing turns that from an architectural inconvenience into a deadline. QuSecure’s QuProtect platform inventories the cryptography in use, moves live traffic onto the NIST post-quantum standards ML-KEM and ML-DSA, and produces a cryptographic bill of materials mapped to the mandates — what the company calls crypto-agility, and what it argues costs 90 to 97 percent less than ripping out and replacing network-facing systems. Krauthamer was QuSecure’s Chief Product Officer before taking the top job, and has become one of the most quoted public voices on what quantum computing does to encryption.

Career Highlights

• Co-founded QuSecure in 2019, which the company describes as driven by the need for a more agile approach to cryptographic security.
• Served as QuSecure’s Chief Product Officer before becoming Chief Executive Officer.
• Led the company to No. 526 on the 2026 Inc. 5000 list of America’s fastest-growing private companies, ranked on revenue growth from 2022 to 2025.
• Won a Silver Stevie Award as Most Innovative Woman of the Year in Technology in November 2022.
• Named to the inaugural Techstrong Group “Quantum Security 25” and given Inc.’s 2026 Female Founders Award, both announced in March 2026.
• Forbes 30 Under 30 honouree, and a World Economic Forum speaker on quantum computing and AI security.
• Oversaw QuSecure’s move from research into operational defence programmes: TREX for the Office of the Under Secretary of Defense, NetModX and Operation Jailbreak for the Army, and in 2026 the Army’s PCC6 capstone programme.
• Holds, through the company, a facility clearance for classified work, an Army Interim Authority to Test, and U.S. Air Force TACFI sponsorship toward Impact Level 6 — the Defense Department cloud level for information classified up to SECRET.
• QuSecure was cited as a benchmark for industry-wide adoption strategies in the Securities and Exchange Commission’s 2025 Post-Quantum Financial Infrastructure Framework, and named Global Product Leader in post-quantum cryptography by Frost & Sullivan.

Professional Journey

Krauthamer studied symbolic systems at Stanford — the interdisciplinary programme that sits between computer science, philosophy, linguistics and cognitive science — and her public work has kept that generalist’s angle: she writes and speaks less about cryptographic primitives than about what happens to institutions when the assumptions underneath their security stop holding.

QuSecure was founded in 2019, with Krauthamer as one of four co-founders alongside Garrison Buss, Austin Bosarge and Dave Krauthamer. Its bet was that the post-quantum transition would not be won by shipping new algorithms — NIST was already standardising those — but by solving the operational problem of finding, governing and swapping cryptography in live systems that nobody has a complete map of. She took the Chief Product Officer role, and the early public profile of the company ran largely through her: interviews, podcasts, panels and a run of Forbes columns on the quantum threat to language models, on China’s quantum announcements, and on what technology leaders should actually do about post-quantum cryptography. In November 2022, still as CPO, she won a Silver Stevie Award as Most Innovative Woman of the Year in Technology.

The company’s growth came through the U.S. government. QuSecure describes itself as having achieved the first deployment of post-quantum cryptography for the U.S. government, and its timeline runs from a facility clearance and an Army Interim Authority to Test, through Air Force TACFI sponsorship toward Impact Level 6 authorisation, to a series of operational programmes: TREX under the Office of the Under Secretary of Defense, NetModX and Operation Jailbreak with the Army, and the Army’s PCC6 capstone programme in 2026. An SBIR Phase III procurement contract made it a sole-source provider of post-quantum cryptography to federal agencies.

By the time she moved into the chief executive role, the commercial market had begun to arrive as well — banking, telecom and critical infrastructure, driven by compliance deadlines converging on 2030. Her own framing of the 2026 position is that the timelines for quantum-safe adoption have compressed and that the year matters as the foundation for the growth that follows. The company was ranked 526th on the 2026 Inc. 5000, named to Forbes’ America’s Best Startup Employers, made a finalist in the MIT Sloan CIO Symposium Innovation Showcase, and took Gold at the 23rd International Business Awards. In March 2026 she was named to the first Techstrong Group Quantum Security 25 and received Inc.’s Female Founders Award.
