The Israeli cryptography lab that might have built the best blockchain scaling technology on Earth. StarkWare uses zero-knowledge proofs (STARKs) to verify thousands of transactions in a single mathematical proof — no trust required. Their tech powers StarkNet (an Ethereum L2) and StarkEx (used by dYdX, Immutable X, and Sorare). Valued at $8 billion. Co-founded by Eli Ben-Sasson, who literally co-invented the STARK proof system as an academic. This isn't a startup that borrowed technology. They invented it.

starkware.coTHE ORIGIN STORY
Eli Ben-Sasson is a computer science professor at Technion who spent decades researching zero-knowledge proofs. In 2018, he co-founded StarkWare with Uri Kolodny and others to commercialize STARK technology — a type of zero-knowledge proof that can verify computations without revealing the underlying data.
The team spent years building the math before shipping products. StarkEx launched in 2020 as a scaling engine for specific applications (dYdX for derivatives, Immutable X for NFTs, Sorare for fantasy sports).
StarkNet launched in 2021 as a general-purpose L2 network on Ethereum.
WHAT THEY ACTUALLY DO
StarkWare builds and licenses zero-knowledge scaling technology. StarkEx is a permissioned service — specific applications pay to use StarkWare's scaling engine.
StarkNet is a permissionless L2 where anyone can deploy smart contracts. Revenue comes from StarkEx licensing fees, StarkNet sequencer fees, and the STRK token ecosystem.
THE PRODUCTS
StarkEx — scaling engine for specific applications (dYdX, Immutable X, Sorare). StarkNet — general-purpose L2 network on Ethereum.
Cairo — the programming language for building on StarkNet. STRK — the governance and utility token for the StarkNet ecosystem.
HOW THEY GREW
Technology-first approach. While competitors rushed to launch tokens and marketing campaigns, StarkWare spent years on the mathematics.
The academic credibility (Ben-Sasson co-invented STARKs) gave them instant legitimacy. Signing dYdX, Immutable X, and Sorare as early StarkEx customers proved the technology worked at scale before StarkNet launched.
THE HARD PART
Developer adoption on StarkNet. StarkNet uses Cairo — a custom programming language — instead of Solidity (which most Ethereum developers already know).
This creates a learning curve that Arbitrum and Optimism don't have. Competition from zkSync (which uses Solidity) is a direct threat.
The STRK token launch was also controversial due to airdrop distribution decisions.
