One company conversation, not two private AI histories

Cofounders make decisions together, but their AI work often happens apart. One founder researches a market in ChatGPT, another tests positioning in Claude, and the reasoning reaches the other person as a screenshot or a compressed summary.

Unium gives cofounders shared chats and projects where both people can see the same history, add context, and continue the work. The conversation belongs to the company decision rather than one founder's account.

Switch models as the work changes

Early-stage work crosses disciplines constantly. A product question becomes a technical question, then a customer email, then a pricing argument.

Choose GPT, Claude, Gemini, or another available model for the next message without restarting the conversation. The model changes, while the accumulated company context stays in the thread.

Use projects as a lightweight company memory

Create projects for areas such as product, fundraising, hiring, or a launch. Related chats can share project context, and a new collaborator can join the project with the appropriate role.

This is not a replacement for source documents or a decision log. It is a practical place to keep the questions, alternatives, and AI-assisted reasoning that led to a decision.

Share access without sharing passwords

Each founder uses their own account. Invite a cofounder as an editor, give an adviser viewer access to a specific chat, or add a teammate to one project without revealing unrelated private conversations.

That is safer and easier to understand than sharing one AI login, where personal history, memory, and billing become mixed together.

Keep early-stage costs variable

Startup AI usage is uneven. A launch week may involve heavy research and drafting, followed by a quieter month. A shared prepaid wallet lets the team pay for paid-model usage without committing to another plan for every person.

Credits can be shared independently of chats, and owners can see member usage or set monthly limits. Free models may also be available when the wallet has no balance.
