11Seas

11Seas builds the AI agents and automations that take work off your plate — and the web and mobile apps that run your business on top of them. We're a full-stack agentic AI and automation agency. On one side, we design and ship AI agents and multi-agent systems using Claude, Claude Code, and OpenAI/ChatGPT APIs, backed by careful prompt engineering — the kind of agents that make real judgment calls, not just chatbots. On the other, we build n8n workflow automation and business process automation that connects your CRM, GoHighLevel, HubSpot, Google Workspace, and voice/SMS tools through clean API integrations, replacing hours of manual busywork with a system that just runs. When you need the product itself, not just the automation behind it, we build it on the same AI-native stack top teams are standardizing on: Next.js, React, and TypeScript on the front end, Supabase and PostgreSQL for the database and auth, and Vercel for deployment — fast, scalable, and built to ship in weeks, not quarters. Need it on phones too? We build the same experience natively with React Native and Flutter, so your web app, iOS app, and Android app share one backend and stay in sync. What sets us apart: we don't hand you a demo and disappear. We scope the workflow, build it against your real data, test it against edge cases before it touches a customer, and hand over something you can actually run — with documentation and support, not a black box. If you're looking for an agency that can design the AI agent, automate the workflow around it, and ship the web and mobile app it lives in — all under one roof — let's talk.
