Sandeep Nailwal is an Indian entrepreneur and engineer who holds an MBA from the National Institute of Industrial Engineering and began exploring blockchain after encountering Bitcoin in 2013 and building his first Ethereum dApp. He co-founded Matic Network — later rebranded Polygon — in 2017 to scale Ethereum, and over time became the most prominent and longest-serving member of the founding team as others stepped back. In 2025 he stepped up as CEO of the Polygon Foundation, steering the ecosystem's grants and strategic direction, including a pivot toward regulated stablecoin payments. He has also been an active backer of crypto causes, including a high-profile COVID-relief fund in India.
Jaynti Kanani is a software engineer who previously worked as a data scientist at Housing.com before turning to blockchain and Ethereum scaling. He co-founded Matic Network (later Polygon) in 2017, where his work on scalability, proof-of-stake architecture, and decentralized applications was foundational to the early protocol. He stepped back from active involvement in the project in the years following Polygon's growth.
Anurag Arjun is a co-founder of Matic Network (later Polygon), which he helped start in 2017. A trained engineer with a background in product and project management, he brought planning and execution experience to the early team building Ethereum scaling infrastructure. He later stepped back from Polygon and went on to co-found the modular data-availability project Avail.
Mihailo Bjelic is a Serbian engineer and entrepreneur who joined the Polygon founding team, formally becoming a co-founder in 2021 as the project expanded its scaling research and zero-knowledge ambitions. He helped shape Polygon's multi-product strategy, including its zkEVM and AggLayer efforts. He departed the project in 2025, leaving Sandeep Nailwal as the last remaining member of the original founding team.

Polygon PoS is an Ethereum-compatible proof-of-stake network that offers low fees and fast confirmations for EVM applications, long used as a scaling venue for DeFi, NFTs, gaming, and enterprise pilots. Fully compatible with Ethereum tooling, it lets developers deploy existing Solidity contracts with minimal changes while settling value back to Ethereum. It has historically been one of the highest-usage Ethereum-adjacent chains by daily active addresses, and is being upgraded as part of Polygon's broader AggLayer-centric architecture.
AggLayer is Polygon's cross-chain protocol designed to aggregate liquidity, users, and state across many independent chains so they feel like a single network. Rather than forcing apps onto one monolithic chain, AggLayer connects sovereign chains — including Polygon's zkEVM and partner rollups — and coordinates secure cross-chain transactions anchored to Ethereum. The goal is to solve the fragmentation that comes from a proliferation of L2s, giving users near-seamless movement of assets and unified liquidity while each connected chain keeps its own execution environment.
