Build Customer Portals
using Existing Code
with Automation
for SaaS

SaaS products need multi-tenancy, subscription billing, and activation flows. Greta ships all of this pre-wired — Stripe, auth, onboarding, and analytics from day one.

Set up automated workflows that run tests, enforce code quality, lint, and deploy to production — so you focus on building features, not maintaining infrastructure.

The Problem

The SaaS stack is broken by default.

01

Multi-tenancy from scratch takes months

Building tenant isolation, per-seat billing, and role-based access from scratch is error-prone and expensive before you've validated anything.

02

Activation gaps kill trial conversion

Most SaaS products lose 60–80% of trial users before they see value. Onboarding is an afterthought, not a system.

03

Scaling without systems

Manual processes that work at 10 customers break at 100. Growth requires infrastructure most teams haven't built yet.
