Lightspark

Lightspark is a global payments platform founded in 2022 and headquartered in Los Angeles, California. Led by CEO David Marcus (former President of PayPal and Head of Messenger at Facebook), the company is building open, instant, and programmable financial infrastructure on top of Bitcoin and the Lightning Network. Backed by co-lead investors a16z Crypto and Paradigm, alongside Thrive Capital, Coatue, Felix Capital, Ribbit Capital, Matrix Ventures, and Zeev Ventures, Lightspark is positioned at the intersection of traditional finance and the decentralized Bitcoin ecosystem.

Core Products/Services

Lightspark offers three main product lines for businesses:

Grid is the company's flagship global payments API. It allows developers to send, receive, and settle value anywhere in the world across fiat currencies, stablecoins, and Bitcoin—all through a single unified API. Grid supports use cases including cross-border transfers, on- and off-ramps, payouts to contractors and gig workers, debit card issuance, pay-ins and collections, rewards and cashback programs, FX conversion, payroll, and treasury management. It is built on Bitcoin as the underlying settlement layer and designed for 24/7 real-time operation at low cost.

Node is an enterprise-grade managed Lightning Network infrastructure product. It handles all operational complexity of running Bitcoin Lightning nodes—including key management, liquidity provision, channel balancing, routing optimization, and software updates—so businesses can integrate Lightning payments without operating the network layer themselves. Node includes flexible custody options (Remote Key or Operation Signing Key), AI-powered routing via Lightspark Predict, compliance integrations, SSO support, and developer dashboards. It offers Starter and Enterprise pricing tiers.

Spark is a Bitcoin Layer 2 protocol that enables moving bitcoin and bitcoin-native assets (including stablecoins) instantly at near-zero cost while remaining fully connected to Bitcoin's infrastructure. Spark is developed by Lightspark and has been adopted by partners including Tether (via WDK) and Wallet of Satoshi.

UMA (Universal Money Address) is an open-source protocol created by Lightspark that works like an email address for money. It enables interoperable, global payments across any UMA-enabled wallet, exchange, or bank, using Bitcoin Lightning for settlement.

Why Choose Lightspark

The platform's open, Bitcoin-native architecture means lower costs, greater capital efficiency, and freedom from closed financial networks—while still meeting regulatory requirements across jurisdictions.
