AI21 Labs is the Tel Aviv-based foundation-model company co-founded in November 2017 by Yoav Shoham (Professor Emeritus, Stanford), Ori Goshen (serial entrepreneur), and Amnon Shashua (co-founder of Mobileye, OrCam, and One Zero Digital Bank). It is one of the very few non-American companies operating at the foundation-model layer of the AI economy. The company's Jurassic-1 model (August 2021) was the first large language model released publicly outside the United States. As of August 2023, AI21 Labs was valued at $1.4 billion in its Series C round led by Walden Catalyst with participation from Google, Nvidia, Pitango, Samsung Next, and Shashua himself.
AI21's consumer product Wordtune has approximately 10 million users. Its enterprise product line — AI21 Studio, the Jurassic and Jamba foundation models, and the Maestro orchestration layer — serves Fortune 100 customers including Carrefour, Clarivate, eBay, Guesty, Monday.com, and Ubisoft. The company is, by some accounts, Israel's largest pure-play foundation-model operator and one of the structural anchors of the country's emerging AI sovereignty thesis.

The Founders
Yoav Shoham is Professor Emeritus of Computer Science at Stanford University and a former Principal Scientist at Google. His academic work spans AI, game theory, and multi-agent systems, with foundational publications in each. Shoham describes himself as a "professor in rehab" — he stepped back from full-time academic work to co-found AI21. He is Co-CEO.
Ori Goshen is a serial entrepreneur with more than 15 years in technology leadership before AI21. He co-founded CrowdX, a network-analytics firm acquired by Cellwize in 2016, and Fring, an award-winning VoIP service acquired by Genband in 2013. He is Co-CEO and leads product, operations, and go-to-market.
Amnon Shashua is the company's Chairman and the most publicly visible Israeli AI figure of the post-2017 era. He co-founded Mobileye in 1999 (acquired by Intel in 2017 for $15.3 billion — the largest Israeli technology acquisition in history at the time), founded OrCam (the assistive-technology device-maker for the blind and visually impaired, valued at approximately $3 billion), founded One Zero Digital Bank, and serves as CEO of Mobileye Global. Shashua came on board AI21 a few months after Shoham and Goshen began. By Shoham's account, the initial conversation was about funding a separate education project, WeCode; Shashua "donated to the project" within ten minutes, then asked what else Shoham was working on, and joined AI21 as a strategic partner rather than a passive investor.
The Company Strategy
AI21 was founded with the stated mission of "changing the way people read and write" through natural language AI. The name AI21 itself is shorthand for "AI for the 21st century." From founding through late 2020, the company operated in what Shoham has called "sleepy genius lab" mode — building infrastructure without releasing a public product.
The first product release was Wordtune in October 2020 — a browser extension and writing assistant that rewrites sentences for clarity, tone, and style. Wordtune was named one of Google's favorite Chrome extensions of 2021. The product has accumulated approximately 10 million users and competes most directly with Grammarly, the Silicon Valley AI writing-assistant category leader.
In August 2021, AI21 launched AI21 Studio, its developer platform, alongside Jurassic-1 — the first publicly released foundation model with a token vocabulary above 250,000, larger than OpenAI's GPT-3 at the time. Jurassic-1 was the first publicly available large language model developed outside the United States. The product positioning was direct: NLP-as-a-Service for developers and enterprises, with the same accessibility AWS brought to cloud computing.
Subsequent model generations have evolved the architecture significantly. Jurassic-2 (March 2023) added instruction-following and enterprise tuning. The Jamba family (2024) introduced hybrid architecture for efficient long-context processing — a structurally different approach than the pure-Transformer designs of GPT-4 and Claude. Jamba Reasoning 3B (2025) targets on-device computing. Maestro (2025) is the orchestration layer that coordinates multiple model calls and external tools for enterprise workflows.
The Funding Trajectory
AI21's capital trajectory reflects the broader generative-AI investment cycle that the company helped initiate.
- January 2019 — $9.5 million seed round
- November 2020 — $25 million Series A led by Pitango First; called "Israel's largest venture capital fund" round of the year
- November 2021 — Walden Catalyst announced $20 million additional investment
- July 2022 — $64 million Series B led by Ahren Innovation Capital, with participation from Shashua, Pitango Ventures, TPY Capital, and Mark Leslie. Valuation: $664 million
- August 2023 — $155 million Series C led by Walden Catalyst, with Google, Nvidia, Pitango, Thailand's SCB10X, European b2venture, Samsung Next, and Shashua. Valuation: $1.4 billion — Israeli unicorn status
- 2025 — Series D round (details not publicly disclosed; Nvidia and Google participated)
Estimated 2023 annual revenue was $50–60 million. Employee count was approximately 200 with stated plans to recruit 100 more.
Why AI21 Matters in Israel
Three structural reasons AI21 occupies a distinctive position in the Israeli technology economy.
First, it is the only Israeli foundation-model company operating at the global frontier of model development. Foundation models — the underlying neural networks that power generative AI applications — are dominated by a small number of US labs (OpenAI, Anthropic, Google DeepMind, Meta) plus a small cohort of Chinese labs (Baidu, Alibaba, ByteDance) and a single European lab (Mistral). AI21 is the only Israeli operator at this layer. Every other Israeli AI company is built on top of foundation models trained elsewhere.
Second, it is one of the foundational anchors of Hebrew-language AI. Hebrew is a structurally low-resource language for foundation-model training; the corpora available are smaller and more fragmented than for English or Chinese. AI21 has built specific Hebrew-language capability into Jurassic and Jamba that is materially more sophisticated than what general-purpose US-trained models offer. Israel's AI sovereignty thesis — the argument that the country requires domestic foundation-model capability for strategic, defense, and cultural reasons — runs principally through AI21.
Third, the Shashua connection. Amnon Shashua is the single most consequential figure in Israeli AI of the past two decades. Mobileye redefined the global automotive technology category. OrCam built one of the most consequential assistive-technology businesses in the world. One Zero Digital Bank is reshaping the Israeli retail-banking economy. AI21 sits inside the same Shashua cluster — and inherits the network, the institutional credibility, and the customer-introduction depth that comes with it.
Customers, Products, and Commercial Reach
AI21's enterprise customer base, as publicly disclosed, includes:
- Carrefour — France-based global retail giant
- Clarivate — academic and intellectual-property data services
- eBay — global e-commerce marketplace
- Guesty — short-term-rental property management software
- Monday.com — Israeli work-management platform (Nasdaq: MNDY)
- Ubisoft — French video game publisher
- Multiple unnamed Fortune 100 enterprises
The commercial positioning has evolved. The original "NLP-as-a-Service" framing of 2021 gave way, after the broader ChatGPT-driven generative-AI cycle began in late 2022, to enterprise-AI-platform positioning. AI21 has consistently differentiated against OpenAI on the basis of enterprise reliability, multi-tenancy, and the structural cost-efficiency of the Jamba architecture for long-context use cases.
Why AI21 Matters Now
The 2025–2026 enterprise-AI procurement cycle is moving from foundation-model selection toward orchestration, agent, and reasoning layers. AI21's Maestro release in 2025 positions the company at exactly the layer the next cycle of enterprise spend is targeting. The Jamba architecture — with its long-context efficiency — is structurally well-positioned for the agentic-AI workloads that are becoming the dominant enterprise pattern.
The strategic question for AI21 over the next 24 months is whether it can continue to compete at the foundation-model frontier without the order-of-magnitude capital advantage that OpenAI, Anthropic, and Google DeepMind hold. The company's positioning — efficient architecture, enterprise focus, deep Hebrew-language capability, Shashua network depth — gives it a sustainable niche. Whether that niche compounds into category leadership or whether AI21 settles into a strategically important but commercially second-tier position is the open question of the next funding cycle.
FAQ
Who founded AI21 Labs?
AI21 Labs was co-founded in November 2017 by three principals: Yoav Shoham (Professor Emeritus of Computer Science at Stanford and former Principal Scientist at Google), Ori Goshen (a serial entrepreneur who previously co-founded CrowdX and Fring), and Amnon Shashua (co-founder of Mobileye, OrCam, and One Zero Digital Bank, who joined a few months after Shoham and Goshen and serves as Chairman).
What is Jurassic-1?
Jurassic-1 is the first large language model AI21 Labs released publicly, in August 2021. It was the first publicly available LLM developed outside the United States, with a token vocabulary of more than 250,000 — larger than OpenAI's GPT-3 at the time. Jurassic-1 launched alongside AI21 Studio, the company's developer platform for building text-based applications.
What is Wordtune?
Wordtune is AI21 Labs's flagship consumer product — an AI-powered writing assistant that rewrites sentences for clarity, tone, and style. Released in October 2020, Wordtune has approximately 10 million users and is the principal competitor to Grammarly in the AI writing-assistant category. It is available as a browser extension and integrates with Microsoft Word.
How is AI21 Labs valued?
AI21 Labs was last publicly valued at $1.4 billion following its August 2023 Series C round of $155 million, led by Walden Catalyst with participation from Google, Nvidia, Pitango, Samsung Next, and co-founder Amnon Shashua. The Series D round in 2025 brought further capital from existing and new investors including Nvidia and Google; valuation details for Series D have not been publicly disclosed.
How does AI21 compete with OpenAI and Anthropic?
AI21 competes on three dimensions: architecture (the Jamba hybrid architecture is structurally more efficient than pure-Transformer designs for long-context workloads), enterprise focus (the company has consistently prioritized Fortune 100 reliability and multi-tenancy over consumer-product flash), and Hebrew-language capability (AI21 has built deeper Hebrew-language support than general-purpose US-trained foundation models). The company positions itself as the enterprise-AI alternative for organizations that need foundation-model capability without single-vendor lock-in to a US lab.
What is Maestro?
Maestro is AI21 Labs's AI orchestration system, launched in 2025. It coordinates multiple foundation-model calls and external tools across enterprise workflows — the layer between raw foundation-model capability and end-to-end agentic enterprise applications. Maestro is central to AI21's positioning for the 2025–2026 enterprise-AI procurement cycle.
Is AI21 Labs publicly traded?
No. AI21 Labs is privately held. The company's most recent disclosed valuation is $1.4 billion (Series C, August 2023). No IPO has been announced as of mid-2026.
