What you can build

Three ways in, one foundation.

Hello Purple is not only a publication. It is also a technical foundation you can build on top of. What you build, and how far you take it, is up to you. Here are the three ways people come in.

01Build for yourself Experience the market exactly the way you have always wanted to.02Build a product Ship the financial app you wish existed, to your own users.03Embed finance Give your users finance inside your product, without becoming a fintech.

For yourself

Build your own financial app, for an audience of one.

You already know what you wish existed: your own dashboard, your own view of the market, your own way to act on it. With the building blocks here you can make it, and connect it to your own supported account, without asking anyone for permission.

Automations and views built exactly the way you think

You do not need us to build this. We just make it the fastest place to do it, and we show you what is possible in Reports.

Build a product

Launch an app with your own users.

With AI, building an app became easier than ever, and open to any ambitious builder. Financial apps did not follow: the market data, the execution and the licensed infrastructure stop people the way they always have. That is the part we already own, so the technical work becomes about as ordinary as building anything else. Your product, your users, your name.

Your own branded investing or trading product

A partner working out what is possible, with you, not a wall of terms

We work out the right shape for your market with you, and the earlier you come, the faster we get there.

Embed finance

Put finance inside your platform.

You have a product and an audience already, and you want a payment flow, a payout or an investing rail embedded cleanly inside it. This is bespoke B2B work and we shape it with you, one to one. We intend to be the easiest option on the market: more flexible than single-use platforms, and faster to work with when you want to ship.

Collection accounts and payout flows that fit your product
Embedded investing or payment rails, under your brand
A direct B2B relationship, shaped to your use case

Example: a platform for advisors that routes recurring payments through one collection account, so the advisor stays in the loop and the flow fits how the product already runs.

One block, one product

Pick up a capability. Put down a product. Most builds need one of these, not all of them.

You start with

A live market data stream

Prices, instruments, history.

You end up with

A trading app for coffee traders

Only the instruments they care about, in the words they use.

One capability. You bring the audience and the taste; the market data and the execution are already there.

Powered by the Purple Group foundation

Under the hood, these building blocks connect to proven, licensed infrastructure across the group, including our brokerages and payment institution. Which providers a given build connects to depends on the product and your market. We talk you through the specifics when we scope your build.

Where you can build today

Availability depends on where you and your users are. Some markets are open to hands-on building now; others open up as the regulatory picture becomes clearer. Tell us your market and we will tell you what is possible today.
