Companies using Rust in Israel

Companies in Israel using Rust
List of companies In Israel that use Rust along with some information on what they use it for.

On this page we try to showcase all the companies in Israel that use Rust. We include local companies and international companies that have a local office where some people write Rust. For each company we try to include some "evidence". e.g. A link to a presentation they gave. The fact that they hosted a Rust event. If they have Open Source projects written in Rust.

In addition we would like to have a few paragraphs about each company answering the questions:

  • What do they develop in Rust?
  • Why did they pick Rust?
  • Why is Rust good for them?
If you know about more companies, if you know more details about the use of Rust in these companies, if you have other evidence that they use Rust, please send a Pull-Request to improve this page or contact Gabor.

EurekaLabs

Eureka Labs is building the next-generation block builder for Ethereum. This means processing vast volumes of transactions in real time, simulating them, and assembling them into blocks at the same pace as the network itself. Achieving this demands extreme throughput, ultra-low latency, and rock-solid reliability - the system must handle transactions in peak moments without bottlenecks or failures.

To meet these challenges, we turn to Rust, with its unique mix of performance and safety. By combining concurrency with an actor-based architecture, we design lightweight, independent components that coordinate seamlessly at scale, keeping the system both efficient and resilient.

  • They are building a cloud financial management platform and all (well, probably 99%) of the backend is written in Rust!

StarkWare

StarkWare is an Israeli deep-tech company developing a platform that enables scalable transactions on blockchain. Our technology is based on zero-knowledge cryptographic proofs: connecting a theoretical model with practical computer science, significantly streamlining transaction verification and solving the scalability challenge. This makes it possible to execute thousands, and even tens of thousands, of transactions per second on the Ethereum network.

To handle the complexity of the computations and proofs we run, we need a language that is both highly efficient and extremely safe, especially in memory management. That’s why we are currently migrating our entire codebase from Python to Rust – a move that makes the system more robust, resilient to developer errors, and capable of delivering top-tier performance.

In addition, we developed Cairo – a unique programming language for building applications on our network, inspired by Rust. Cairo was born out of our drive to always stay at the forefront of technology, giving developers modern, relevant tools and a solid, safe, and efficient foundation at scale.

Rust is a cutting-edge language, positioned at the very top of the programming world – and that’s exactly where we aim to be. Using Rust reflects StarkWare’s technological mindset: choosing the very best tools to build infrastructure that is trustworthy, scalable, and efficient.

Tabnine

Tabnine's Unique Rust Architecture

Tabnine is an AI code assistant built to integrate seamlessly into the developer’s workflow. Its architecture combines the power of server-side infrastructure with a strong, lightweight presence on the client side—right where the developer’s code and IDE reside.

At the heart of this client-side presence is Tabnine’s Rust application, a core component that makes the product stand out. Unlike many developer tools that rely solely on the cloud, Tabnine runs directly on millions of end-user machines, across multiple operating systems and architectures. This approach ensures speed, reliability, and flexibility in real-world coding environments.

The Rust application itself brings several unique capabilities:

  • Massive scale: installed on millions of devices worldwide.
  • Cross-platform execution: runs smoothly on diverse operating systems and hardware.
  • Self-managed updates: powered by an in-house auto-update mechanism.
  • Local persistence: capable of spinning up both a vector database and a relational database on the client side.
  • Robust connectivity: supports secure communication with Tabnine’s servers in varied network conditions, including certificate-based authentication and proxy environments.

This combination of large-scale deployment, advanced local functionality, and secure connectivity makes Tabnine’s Rust application a rare example of client-side AI software that is both powerful and production-ready. It bridges the gap between cloud AI inference and the day-to-day developer experience, ensuring that Tabnine feels not just like a tool, but like an integral coding companion.

Varonis

  1. We are developing a next-generation endpoint agent in Rust as part of our Data Loss Prevention (DLP) solution, ensuring secure and efficient protection directly on user devices.

  2. By leveraging Rust’s safety and performance, we’re building core endpoint capabilities that detect, monitor, and prevent data exfiltration at scale.
