What NotificationAPI does
NotificationAPI, which rebranded to Pingram in 2024, is a developer-focused unified messaging API platform headquartered in Canada (Toronto, with operations referenced in St. John's, Newfoundland). The company consolidates Email, SMS with managed A2P 10DLC compliance, automated Voice calls, and an incoming WhatsApp channel behind a single flat JSON API endpoint, replacing the need for developers to integrate separately with providers such as SendGrid, Twilio, Resend, and ElevenLabs. Its technical differentiators include managed end-to-end US A2P 10DLC registration, a multi-tenant architecture for agencies and SaaS platforms, native integrations with AI voice providers (ElevenLabs, OpenAI, Deepgram), and an API surface optimized for AI agents via skills, MCP, and a machine-readable llms.txt file.
Pingram operates a hybrid product-led growth and API-first go-to-market. Developers self-serve through a free tier (3,000 emails, 100 SMS/calls per month, no credit card required) at app.pingram.io/signup, with paid plans starting at $20/month and custom multi-year enterprise contracts available via Calendly-booked demos. Pricing combines a recurring subscription base with usage-based charges for SMS and Voice. The customer base spans Y Combinator startups (GhostEye, Minicor), venture-backed mid-market firms (Zingage, Copecart, FullEnrich), and enterprise accounts (Spellbook, serving ~4,000 law firms across 80 countries), suggesting traction across the SMB-to-enterprise spectrum. Distribution is augmented by marketplace listings on Auth0 and Supabase and by presence on AI agent platforms (ChatGPT, Claude, Cursor, Lovable, Bolt). The company is privately held with 1-10 employees, no disclosed funding rounds, and certifications including SOC 2 Type II, GDPR, and HIPAA.
