The Real Problem
Engineering is treated like labor. Not leverage.
4M Labs builds AI infrastructure and operational software for companies that need leverage, not headcount.
Websites do not convert
Conversion WebsitesThe company is credible offline, but engineering is treated as a cost center, not a competitive advantage.
MVP scope drifts
MVP & Product BuildsThe idea keeps expanding because there is no leverage culture. Every change needs more people, not better systems.

Persistent memory for AI agents
Challenge
AI-assisted development creates useful context quickly, but that context often disappears after a chat, branch, or task ends. Teams need a way to retain decisions, lessons, and reusable project knowledge.
Outcome
A live product at squishplugin.dev providing persistent memory that connects across AI tools and coding environments.

Read case studyHow We Work
From strategy call to production handoff.
Every build follows an 8-week process. No surprises, no scope creep, no open-ended billing. Your team knows exactly what is coming.
Week 1
Discovery + Architecture
We audit your workflow, map constraints, and define the architecture. By the end: approved handoff criteria and a build plan.
Week 2
Prototype + Integrations
We build a working prototype with key integrations. Your team sees exactly how it works before production code is written.
Weeks 3-4
Core Build
Senior builders implement the full system. A new artifact every day. No dead weeks.
Weeks 5-6
Production Hardening
Hardening, edge cases, error handling, monitoring. Built to not break, not to look good in a demo.
Week 7
Testing + QA
Full testing: unit, integration, and user acceptance. Your team tests the real system, not a demo.
Week 8
Launch + Handoff
Deploy, documentation, analytics, and full handoff. Your team can own the system with zero dependency on us.
