Business

Brightline Labs — Founders’ Fund 🚀

Three co-founders, one pre-launch budget. We’re pooling our own money to build Brightline before we incorporate: software, legal fees and our first prototype. Every spend over $500 needs two of us to agree.

How CoTreasury keeps everyone honest

AI Treasurer

The impartial referee.

The AI checks transactions and treasury activity against the rules, helps people understand the ledger, points out anything that breaks the rules, and answers questions about what happened.

It cannot approve requests, move money, or rewrite the ledger.

Shared Ledger

One record everyone can check.

Every contribution, payout, approval, and transaction is recorded with its status and history. Once recorded, financial history isn’t something one person can simply edit behind the scenes.

Collective Rules

Decisions are made by the people authorized to make them.

Your group decides who can approve payments and how many approvals are required. CoTreasury applies those rules consistently, and the AI can’t change them.

PayPal

The money stays and moves through PayPal.

Approved in or out payments are processed through PayPal and verified before CoTreasury records them. The AI never becomes the person holding or moving the money.
