Build the financial world you imagine.
For fifteen years Purple built fintech piece by piece: trading, investing, payments, technology. Now that foundation is open to build on. We publish the map, so you do not have to guess where this is heading.
We map agentic finance.
Tests of the tools builders actually use, case studies of what we build on the foundation, and analysis of where the ecosystem is heading. Nobody who is actually building on finance is writing this down, so we do.
A safety check for the trading tool you built with AI
Building a trading or investing tool with a coding agent takes an evening, and checking what that tool can do with your account takes about one more. These are the nine questions I'd go through, starting with the key and ending with the off switch.
Spending limits for AI agents: soft, hard and signed
Card networks, payment platforms and fintechs have all announced ways to let an AI agent pay. They all set a budget, but they put it in very different places, and that place decides whether the limit holds.
Which brokers let AI trade your account, and how far each one goes
In 2026, broker after broker opened a door for AI assistants. Some let the AI look, some let it trade after you say yes, a few let it trade on its own. What matters most is where that yes is enforced.
Whatever you are building, there is a way in.

An AI will write anyone a strategy. Knowing whether it is any good is the hard part.
