Helius Tech Stack

Enterprise Solana infrastructure: RPCs, APIs, and validator services

Software Development Remote 11–50 employees Founded 2022 Privately Held

Helius operates critical infrastructure for Solana development — RPCs, APIs, data streaming, and validator services — built on a polyglot stack (Go, Rust, C++, TypeScript) optimized for low-latency, high-throughput blockchain queries. The engineering-heavy headcount with senior/staff concentration signals deep infrastructure work; active projects confirm this (API performance, latency-critical systems, multi-petabyte ledger indexing). Migration away from Datadog toward internal observability tools indicates a shift toward in-house control of visibility as operational complexity scales.
