About Gaku

AI-powered Shared Inbox, CRM and autonomous AI Agents for B2B

Gaku is an enterprise-grade, multi-tenant B2B SaaS platform that combines a shared team Inbox (Telegram / WhatsApp), project-scoped CRM, and autonomous AI agents with fail-closed policy guardrails. Built for agencies, customer support, and sales teams that need an all-in-one messaging and workflow hub. 🌟 Key Capabilities: • Shared Team Inbox: Multi-channel messaging, real-time sync, manual manager takeover / AI handoff, team assignments. • Project-Scoped CRM: Leads, client cards, tasks, calendar, idempotent Website Intake API with UTM tracking. • AI Agents Runtime: Channel-bound autonomous responders powered by LiteLLM with strict 12-tool permission policy (AIPolicy), routing, and audit logs. • Multi-Tenancy & Access: Tenant, company, and project isolation; granular role-based permissions (RBAC), team shifts, and work presence. • Billing & Operations: Subscription engine (Paddle integration), promo codes, audit logs, workspace merge, and clean offboarding. 🛠️ Modern Tech Stack: • Backend: Python (FastAPI), SQLAlchemy, Alembic (80+ migrations), PostgreSQL, Redis, Celery (worker + beat). • Frontend: Next.js 15, React, TypeScript, Tailwind CSS (100+ fully typed pages and components). • DevOps: Docker & Docker Compose (dev and production configs with Nginx & Certbot). • Quality: Extensive test suites (Pytest, account/CRM smoke scripts, zero-error production build). 💼 What is included in the sale: • 100% intellectual property (IP) and exclusive source code rights. • Production-ready Docker deployment configs and complete database schema. • Comprehensive documentation, deployment checklist, and test suites. 💡 Opportunity for buyer: Saves an estimated 5–6 months and $30,000+ in development costs. Perfect foundation to launch a branded AI customer service SaaS (competitor to Respond.io, Intercom, Wazzup) or deploy as a white-label solution for clients.

Reason for selling

I am a technical engineer passionate about architecture, security, and building robust full-stack software. I have completed the entire engineering lifecycle, core product features, and testing. However, I don't have the marketing background or dedicated time required to run B2B sales and customer acquisition. I am selling so a marketing-focused founder or agency can take this platform to market and scale it.
