Carl Hoffman

Co-Founder and CEO BasisTech

Last Reviewed: September 18, 2026

Executive Summary

Carl Hoffman is the co-founder and chief executive of BasisTech, a Somerville, Massachusetts company he started with fellow MIT alumnus Steven Cohen in 1995 to apply artificial intelligence to understanding documents and unstructured text written in languages other than English. For most of its history BasisTech was a natural language processing software business: its internationalisation work in 1999 made Lycos and Google the first search engines capable of cataloguing the web in Asian as well as European languages, and its Rosette platform became infrastructure for cross-lingual identity resolution in national security, financial crime and identity verification systems. Hoffman sold Rosette to Babel Street at the end of 2022 and has since run BasisTech as a venture investment and incubation operation, working with roughly forty early- and mid-stage technology companies across the United States and Japan while the company continues to steward the open-source digital forensics tools The Sleuth Kit and Autopsy.

Career Highlights

• Co-founded BasisTech in 1995 and has led it for three decades, through two distinct incarnations of the business.
• Shipped the company’s first website internationalisation products in 1999, enabling Lycos and Google to catalogue the web in both Asian and European languages.
• Delivered the technology behind Amazon’s and Google’s Japan market launches and supported Bing’s and Yahoo’s Asian expansion.
• Built Rosette into a text analytics platform used by governments and financial institutions, and sold it to Babel Street in a deal announced November 2022 and closed that December.
• Worked with the US Intelligence Community on multilingual intelligence analysis.
• Oversees BasisTech’s continued development of The Sleuth Kit and Autopsy as freely available digital forensics tools.
• Earlier served as business development director at the Free Software Foundation and as a director of the Unicode Consortium.
• Investor in Customer Matrix, Diffeo, Lucidworks, Luminoso, PolySwarm, Recorded Future, Tamr and Zoomd; Diffeo was acquired by Salesforce in 2019.
• Adviser to PolySwarm, Thrive Bioscience and the Alliance for Innovative Regulation.

Professional Journey

Hoffman moved to Boston from Okinawa in 1976 and spent roughly a decade at MIT, first as an undergraduate, then as a graduate student and researcher, working as a teaching and research assistant in the AI Laboratory and at Project MAC. That period put him at the source of two things that would define his career: machine understanding of language, and the open technical standards that make multilingual computing possible. He later served as business development director at the Free Software Foundation and as a director of the Unicode Consortium — the standards body whose work he would spend years persuading corporations to adopt.

In 1995 he co-founded BasisTech with Steven Cohen, another MIT graduate, on the premise that the emerging web would have to work in every language, not just English, and that nobody was building the software to make that possible. The bet paid off quickly. The company’s 1999 internationalisation products allowed Lycos and Google to become the first search engines able to catalogue the web in Asian and European languages, and BasisTech went on to deliver the technology behind Amazon’s and Google’s launches in Japan and to support Bing’s and Yahoo’s Asian expansion.

The company’s flagship product, Rosette, applied machine learning and deep neural networks to identify people, places, organisations and events across multilingual text, and became widely deployed for cross-lingual identity resolution — used to protect national security, prevent financial crime and verify identity. Hoffman also worked directly with the US Intelligence Community on multilingual intelligence analysis. In parallel, BasisTech developed and maintained The Sleuth Kit and Autopsy, open-source digital forensics tools for analysing storage devices and extracting evidence.

In November 2022 Babel Street announced it would acquire Rosette from BasisTech, closing the deal at the end of December on undisclosed terms. Hoffman framed the sale as a fit rather than an exit, describing Rosette’s NLP as a natural complement to Babel Street’s open-source intelligence platform. He then turned BasisTech into something different: by his own account he transitioned to venture capital in 2023, and the company now operates as an accelerator and investment vehicle, running a 13,000 square foot workspace in Somerville that houses startups and established companies, and backing early-stage ventures in enterprise data, machine vision and the public sector. He works with around forty companies across the United States and Japan, concentrated in fintech, regtech, cybersecurity, machine vision and information retrieval.

His investment record predates the formal shift — he has backed Customer Matrix, Diffeo, Lucidworks, Luminoso, PolySwarm, Recorded Future, Tamr and Zoomd, with Diffeo acquired by Salesforce in 2019 — and he advises PolySwarm, Thrive Bioscience and the Alliance for Innovative Regulation.
