Diffco AI Methodology
A delivery method built for the AI era, not retrofitted to it.
Code is the cheap part now. Knowing what to build first, which foundation will hold at ten times the users, and what not to build at all is where projects are won.
Senior engineers make those calls. More than 100 AI agents per engineer do the building, around the clock, on our own delivery platform built on Claude Code and OpenAI Codex. A living plan with automatic checks keeps every agent inside the lines.
- You click through your product before we build it
- We bring you the parts of the job you never put into words
- Every architecture decision is written down with the alternatives
- Everything traces back to a goal, which is what makes change fast
- People make the decisions, and AI agents build inside them
- Before release, a person watches it work
- The whole project
is a document you can read
- Read the full methodology

How we build
Seven stages, with a person signing off at every gate.
Every project runs through Production-Ready AI Engineering: seven stages, senior engineers directing 100+ AI agents, a check on every save, and a person signing off at every gate.
- 01
Discover
Human + AIWorkshops and stakeholder interviews with AI in the room. It cross-verifies inputs across calls, docs, and Slack threads, flagging blind spots, edge cases, and contradictions humans miss.
- 02
Plan
AIAI decomposes the work, picks architecture, models, and tools. Surfaces risks, costs, trade-offs, and conflicts between stated requirements, before they become bugs.
- 03
Align
HumanYou review and approve. Every decision is logged: an auditable trail before any code is written. No black box, no scope drift.
- 04
Build
Human + AIAI agents execute the approved plan inside engineered guardrails. Senior engineers steer and unblock. Sprint cadence with working artifacts, not status decks.
- 05
Validate
Human + AIThree independent layers on every release candidate: automated evals, senior code review, and dedicated Human QA, with manual and exploratory testing alongside security, performance, and accessibility checks.
- 06
Release
Human + AIProduction deployment, UAT, knowledge transfer, runbooks. Cutover is documented, reversible, and on a schedule you approve. Your team takes the keys, or we operate it for you.
- 07
Evolve
Human + AILaunch is a milestone, not a finish line. Monitoring, feedback loops, and incremental improvements keep the system compounding, and feed the next discovery cycle.
Every later change re-enters the same loop, and nothing skips a step.

Frequently Asked Questions
Senior engineers direct more than 100 AI agents that write the code and tests, review each other’s work, and keep the plan current, around the clock, on our own platform built on Claude Code and OpenAI Codex. You decide what gets built; the agents do the typing.
No. Issues surface the moment work is saved, when they are cheapest to fix, and the agents do not stop when the office closes. What disappears is the rework from a requirement that changed in March and was noticed in October.
You do, in full, from the first week. The goals, the specifications, the decision log, and the acceptance standards are yours to keep and take anywhere.
That is a normal event here. We show you what the change touches across everything already agreed and built, you approve, and it gets built.
Yes. We add the plan beside your existing code without touching it, and the checks apply to new work from day one. Older areas come under the plan as you touch them.
They go into the plan first. Your requirements, whether SOC 2, HIPAA, PCI DSS, or your own policies, become rules every agent reads before it starts and the checker enforces on every change, including which models may see your code and what data the agents can touch.
