What LINQ PARIS does
Linq (legally Linq App Inc., formerly Linq Technologies Incorporated) is a communications infrastructure company headquartered in Birmingham, Alabama with offices in New York and San Francisco. Its core product is the Linq Partner API, a REST platform (V3) that enables developers to send and receive iMessage, RCS, SMS, and Voice messages with automatic iMessage-to-RCS-to-SMS fallback, group chats, reactions, voice memos, and webhook-based event handling. Linq claims to be the only SOC 2 Type II compliant iMessage API, and ships SDKs for TypeScript, Python, and Go alongside an MCP server that exposes its messaging primitives to AI agents in Anthropic's Claude Desktop. The company also offers Linq Blue (dedicated phone lines for businesses), Linq Zero (call management), Linq One (NFC-enabled digital business cards), the iMessage Agent Store (a marketplace for AI agents built on Linq's infrastructure), Chat Health (predictive deliverability scoring in beta), and Agentcard Payments (conversational commerce processed via Stripe).
The company serves three primary customer segments: AI agent developers (Lindy, Pika, Karpo AI), high-growth enterprise and fintech customers needing messaging infrastructure (Ramp, Clay, Tomo, Kalshi), and smaller developer teams adopting via a free Sandbox tier. The go-to-market combines product-led growth through the Sandbox environment with direct enterprise sales on annual contracts. Monetization is driven by API subscription tiers (Sandbox free trial plus Enterprise annual plans), the Linq Blue dedicated-line subscription, and increasingly by Agentcard Payments transaction-adjacent revenue. Linq has processed 150M+ messages across 1,000+ claimed customer teams, with 30M+ messages flowing monthly across 100+ paying companies. The business model relies on a combination of subscription API access, dedicated phone-line fees, and emerging payment revenue, with CRM integrations (Salesforce, HubSpot, GoHighLevel) serving as the primary enterprise wedge.
