LUFU CRM

A Lightweight CRM for Businesses That Don't Need Salesforce

LUFU CRM was born from a specific technical challenge I wanted to solve: building a production-grade multi-tenant SaaS application on Supabase. But it also addresses a genuine market gap. Small businesses — freelancers, agencies, consultancies — need a CRM, but Salesforce is overkill and HubSpot's free tier is a funnel into an expensive ecosystem. They need something clean, fast, and focused.

Multi-Tenant Architecture

The most interesting technical challenge is the multi-tenant architecture. Every customer (tenant) shares the same database, but their data is completely isolated using Supabase's Row Level Security policies. This means:

• One codebase, one database — no per-customer infrastructure to manage
• RLS policies enforce isolation — even if application code has a bug, data can't leak between tenants
• Shared infrastructure costs — the economics work even at low price points

Getting RLS right for a multi-tenant app is genuinely tricky. Every table needs policies, every query needs to respect tenant boundaries, and you need to think carefully about how joins work across tenant-scoped tables. I built and rebuilt the permission model three times before it felt solid.

What LUFU Does

The feature set is deliberately constrained:

• Contacts — people and companies with custom fields and tagging
• Deals — pipeline management with drag-and-drop stages and weighted forecasting
• Tasks — linked to contacts and deals, with reminders and recurring tasks
• Email — send and receive email within the CRM, with full conversation history on each contact

That's it. No marketing automation, no help desk, no project management. Every feature request gets filtered through the question: "Does this help a small business manage their customer relationships?" If not, it doesn't get built.

Fighting Feature Creep

The CRM market is littered with products that started simple and became bloated. Every user wants one more feature, and saying no is the hardest part of product development. LUFU's value proposition is simplicity — the moment it becomes complex, it loses its reason to exist.

Current Status and What I've Learned

LUFU is in development with a handful of beta tenants. The multi-tenant pattern I've proven here transfers directly to other SaaS products — the architecture, the RLS patterns, the tenant provisioning flow. Even if LUFU never becomes a massive business, the engineering patterns it produced have already paid for themselves across my other products.
