Two Agents. One Continuous Lifecycle.
"We don't hand you a finished portal and walk away. We hand you a portal and the means to keep improving it."
Legacy Portal
As-is behavior, undocumented rules, accumulated debt.
Agent 1 — Rewrite
Extracts and documents logic, rebuilds cleanly in React.
New React Portal
Modern, fully documented, parity-proven architecture.
Agent 2 — Modify
Allows changes to flow in continuously and safely.
Agent 1 — Rewrite
Converts as-is legacy behavior into clean, conventional React, readable by any engineer, not just the agent. Eliminates guesswork by extracting hard-coded business logic directly into structured, documented epics and specs.
Agent 2 — Modify
Embedded directly in your team's workflow, so your existing team can ship changes to the new portal at any time. Changes are automatically validated with parity testing before release, avoiding long-term maintenance decay.
Traditional SDLC vs. Product Sweet AI-DLC
Why a traditional rewrite is old school and how the AI-DLC model transformed Payminty's velocity and cost structure.
Traditional SDLC Rewrite
Outsourced agency or in-house teams using legacy sequential waterfalls.
Product Sweet AI-DLC
AI-powered software delivery that amplifies and empowers your existing team.
Delivery Quality and Auditability — Built In
Four incentive-based stage gates. Real humans verify key deliverables — payment only follows approval.
Document
Legacy code and documentation turned into structured epics, features & user stories.
Refine
Scope, environments, realistic test data & Acceptance Criteria confirmed.
Rewrite
Rebuilt in clean, conventional React and tested continuously in parallel.
Release
Live in PROD, and the Modify Agent is handed to your internal team.
No slop, by design: Total transparency, no long-term lock-in for projects that fail to deliver — never pay for an unvalidated stage.
"Product Sweet allowed our product team to have direct, unambiguous control over our entire stack. From CI/CD pipelines to mobile apps – simply by describing our intent. It fundamentally changed our ability to deliver and allowed us to move faster with less risk."
