Codemix for founders

Build at AI speed.
Ship something real.

Code is cheap now. Product coherence is not.

Vibe-coding tools get you to a demo. Then the real work starts: billing, permissions, onboarding, support, all the boring bits that decide whether people can actually use the thing.

Codemix turns the rough idea in your head into product intent agents and collaborators can build against. Not your latest prompt. The product you mean to ship.

New project

Start with a blank slate or bring your code

Create a project from scratch and Codemix will interview you to build a PRD — or connect a repository and it will discover your domain model automatically.

The demo trap

Fast code is not the same thing as product clarity.

Vibe-coded products look great until someone tries to use them. Then the cracks show: disconnected flows, missing rules and features that contradict each other.

That is not really a code problem. It is a product understanding problem. Most AI coding tools assume the product is fully specified in your head. Codemix helps get it out.

Flows stop connecting

Onboarding looks finished. Then billing, permissions and support all interpret it differently.

Edge cases stay in your head

Refunds, seat limits, upgrades and exceptions live in memory. Agents cannot build from memory.

Every change reopens old decisions

Without a product model, every new feature quietly reinterprets the old ones.

Speed turns into rework

You ship quickly, then spend the saved time fixing assumptions you never meant to make.

Start from a rough idea

Ship in days, not months

The idea in your head is not yet a product brief. Codemix gets it closer before code starts drifting.

You answer focused product questions. Codemix turns that into a brief and an initial plan your future self, collaborators and agents can use.

Project setup

Define what you're building

A short interview surfaces the core intent of your product. Codemix uses your answers to generate a first-draft PRD that captures scope, users, and the most important behaviour — ready to refine in chat.

Keep the product coherent

Build something customers can actually use

Codemix keeps a model of how the product fits together. New work is shaped by the system, not the last prompt.

Concepts, screens, actions and dependencies stay connected. As scope grows, consistency stops depending on your memory.

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.

Hand off without losing control

Give agents and contractors a real brief

You should not have to sit next to every agent or contractor restating the product.

Codemix turns approved intent into scoped implementation work. The person or agent gets what the change means, why it matters and what it touches.

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.

Iterate without breaking things

See impact before you pay for mistakes

The faster you ship, the more expensive blind changes become.

Codemix shows scope and dependencies before work starts, then keeps implementation aligned while it is in flight. Safer iteration, without turning the process into theatre.

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.

  1. 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.

  2. 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

    model the productUnderstand the product, not just the files.
  3. 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

    shape the changeGet the shape right before the build starts.
  4. 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

    write the tasksEveryone works from the same brief.
  5. 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

    answer questions mid-buildGive agents somewhere reliable to ask.
  6. 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

    review what changedCatch the wrong idea before merge.
  7. 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

    ship, then update the specKeep the spec alive after release.
  8. 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.

    A better starting point next time

    bring the context forwardThe next change starts with context.
