Boundaries that split the domain
A service boundary can look clean and still split a concept that belongs together. Product teams pay for that forever.
Project overview
See everything in flight, at a glance
The overview surfaces every active proposal, running task, and recent conversation in one place — no status updates required. Codemix keeps it current as work progresses, so anyone on the team can see what's happening and where things stand.
Technically sound. Wrong for the product.
Good technical reasoning is not enough without product understanding.
Architectural decisions can be technically reasonable and still wrong for the product. A boundary can split a domain concept in half. A platform abstraction can make product work slower.
The issue is not competence. It is context. Without the domain model, architects optimise for the wrong things. Codemix puts the product model in the room before the decision gets made.
Platform abstractions nobody uses right
Infrastructure designed without product context gets bent, worked around and eventually replaced by the teams it was meant to help.
Optimized for the wrong workloads
Scalability and resilience patterns are easy to apply in the wrong place when you don't know where the domain actually concentrates load.
Architecture that fights the domain
When technical structure fights business structure, every feature has to bridge the gap. That friction compounds.
Start from the product
Know what the domain is before you decide how to divide it
You cannot draw good boundaries without understanding the concepts and how they relate.
Codemix surfaces concepts, commands, flows and constraints from real code. You reason from the product domain before decisions harden into contracts.

Follow the domain, not the diagram
Cut seams where the product's concepts actually separate
A seam that looks clean on a whiteboard can still be nonsense in the domain.
Codemix shows which concepts cluster together and which flows cross a proposed boundary. You can see where the seam helps and where it creates permanent integration work.
Task plan
A complete task plan, ready to execute
Once a proposal is approved, codemix breaks it into parallelisable tasks and executes them autonomously. The task plan keeps every behavioural commitment visible while the build is underway.
Review with product context
Assess change impact in terms the product actually cares about
Technical impact is only half the review. The other half is product impact.
Codemix maps proposed changes to affected concepts and flows before implementation starts. Reviews can talk about the product, not just the system.

Build for how teams actually work
Design platform abstractions that fit real product workflows
Platform teams often build from technical needs and assumptions about product teams. Assumptions age badly.
Codemix shows the workflows, constraints and domain concepts the platform has to serve. That turns generic scaffolding into capabilities teams actually use.
Proposal review
Catch the problems before the work starts
Codemix flags gaps in the proposal — ambiguities, missing cases, or things that conflict with how the product already works. Resolve them here, and the work that follows is far less likely to need rethinking.
How it works
How Codemix carries context through the full lifecycle
Most product drift happens in the handoffs: from discussion to spec, spec to task, task to code, and code back to the roadmap. Codemix keeps those handoffs explicit.
- 00start
Start with a conversation or from code
Chat with codemix if you're still at the idea stage, or import your existing codebase.
A product baseline
Start with an interview
Talk through the product in plain English. Codemix turns the important parts into something the team can inspect, question, and build from.
Start with the repo
Connect the existing codebase. Codemix reads how the system behaves today, including the bits nobody remembered to write down.
- 01model
model the product
Codemix builds a working model of the product: the concepts, screens, actions, rules, edge cases, and decisions that explain how it is meant to behave.
A model the team can ask about
- 02proposal
shape the change
Before implementation starts, you can ask questions, edit the spec, and turn a rough idea into a concrete proposal for what should change.
A proposal people can review
- 03tasks
write the tasks
Once the proposal is approved, Codemix turns it into implementation work. Send it to Linear or Jira, hand it to a coding agent, or let humans and agents split it up.
Tasks with the context attached
- 04answers
answer questions mid-build
Implementation always uncovers questions. Codemix gives engineers and coding agents answers from the product model, so they don't have to guess from a ticket title or a nearby file.
Product answers during the build
- 05review
review what changed
Codemix reviews the code against the product decision, not just against style, tests, or neighbouring code. That's where a lot of agent mistakes hide.
Review that checks intent
- 06release
ship, then update the spec
Shipping often reveals details nobody saw at planning time. Codemix helps fold those decisions back into the spec, so the source of truth doesn't go stale the moment the PR lands.
Code and spec brought back together
- 07feedback
bring the context forward
Bring in bugs, customer feedback, support notes, and product signals. The next proposal starts with the context you already built, instead of another round of archaeology.

Ready to design from the product?
Stop making structural decisions from half the map.
Codemix gives architects and platform teams the product's actual domain model. Boundary decisions, platform design and change reviews should be grounded in what the product needs, not what looks tidy on paper.
