# Hello Purple

> Financial infrastructure you can build on, and the reporting that shows what gets built.

Hello Purple is a technology publisher from Purple Technology. Its Reports describe what was built and how; they are not financial advice and do not offer or invite the use of any financial service.

Every report has a Markdown twin at its URL plus `index.html.md`, linked below; read that instead of the HTML page. Each twin opens with a "TL;DR" section (the piece in 3 to 5 bullets, verdict included) and ends with a "For agents" section written for you: exact figures with dates and sources, steps to reproduce, the described tool's limits, links and terms.

Quote freely with attribution: name the author, Hello Purple and the canonical URL, with the publication date, all of which are in the Markdown twin’s front matter. The twin is the reference text of the piece.

## Reports

- [The agent was ready. The bank wasn't.](https://hello-purple.com/reports/the-agent-was-ready-the-bank-wasnt/index.html.md): I asked an AI agent to pay my kids' kindergarten invoices. It turned out to be the most careful party in the payment. The banking infrastructure around it was the weak part.
- [Seven orders, six refusals](https://hello-purple.com/reports/seven-orders-six-refusals/index.html.md): I spent an afternoon trying to make Vibe-Trading misbehave. Seven orders went in, six came back refused. A teardown of the safety layer, and a twenty-minute experiment you can run yourself.
- [Hand the agent the company account](https://hello-purple.com/reports/hand-the-agent-the-company-account/index.html.md): My bank could not let an agent pay for me without my tap. A business account in Singapore can. Here is what that lets a small company do, and the one place a person still says yes.
- [Two people, one finished foundation: how Takumis went from an evening idea to live trades](https://hello-purple.com/reports/takumis-two-people-one-foundation/index.html.md): Takumis is a platform for vibe-building trading strategies. You talk your idea through with an AI, it tests it on data, and then you trade for real.

- [Hand the agent the company account (interactive edition)](https://hello-purple.com/reports/hand-the-agent-the-company-account/interactive/): Five payments an agent can make from a business account, the one that waits for a customer, and what a mistake could cost with and without rules.
