Site builders make pages for humans. Oka also makes your business usable by AI agents: every site ships with an MCP server, an A2A agent card and agentic checkout (UCP), so ChatGPT, Claude or any agent can find you, check availability, book and buy. Behind it, one growth stack for small businesses: site/CMS, booking, store, AI chatbot, WhatsApp AI with human co-pilot, email campaigns, CRM, A/B tests and Google Ads drafts. Think HighLevel, but agent-native.
