Why a financial assistant belongs in iMessage

Money already lives in your messages. The most natural place to handle money is the place those conversations already happen - no app to download, no account to set up, no new interface to learn.

That is exactly why a financial agent is hard to put there.

iMessage was not built for agents. The common workaround is to bridge it from a personal Mac that has to stay awake and online, sending messages from your own number. That is acceptable for a side project. It is not acceptable for a product that moves real money. A financial assistant needs a dedicated line, continuous uptime, rich confirmation flows, group-chat support, and a clean separation between the agent and any one person's device. The bridge approach gives you none of that reliably.

Flip makes financial assistance feel as easy as texting a friend.

Photon makes that possible inside iMessage.

How Photon brings Flip to iMessage

Flip selected iMessage via Photon as its channel, connected to a Photon-managed iMessage line, and shipped. From the user's side, there is nothing to install. You text a number, and it just works. Here is what that feels like in practice.

Payday, handled in one sentence. A user texts "move $500 to savings and pay my half of rent to Sam." Flip moves the money, sends Sam his share, and shows what's left - then waits for a yes before anything goes through.

The group trip financing plan. Add Flip to the group chat and text "@Flip split the Airbnb and the rental between all of us." It reads the thread, does the math, and sends each person their share with a one-tap way to settle - inside the same chat where the trip was planned.

The subscription you forgot about. "what am I paying for that I don't use?" Flip scans linked accounts and texts back the forgotten free trial, the duplicate charge, the streaming service nobody's opened in months - and cancels the ones you confirm.

The dip in stock. A watchlist stock hits a level the user flagged. Flip texts first: "Want to act on this?" It surfaces the moment; the user decides. No trade ever executes without an explicit yes.

Every one of these is a normal iMessage conversation. The difference is that the contact on the other end can actually act.

Native iMessage behavior that Photon provides

With Photon, Flip behaves like a native iMessage contact, with RCS and SMS fallback when needed.

• Confirmation cards render transfers, trades, and splits as native, tappable messages - so "confirm before it happens" is one tap, not a wall of text.

• Typing indicators show when Flip is working on a request.

• Images let users send a photo of a receipt to split, or a screenshot to ask about.

• Native iMessage voice notes keep voice interactions inside the same conversation.

• Group chats let Flip split bills, settle tabs, and track shared expenses where the group already is.

Traction

• Flip circulates over $57 million in connected volume

• 2-3x the retention rates of classic finance apps

• Backed by The House Fund, A16Z Speedrun, Pear VC, ZFellows, and Greg Arrese

• Flip’s founders met at UC Berkeley through Blockchain at Berkeley, the first and premier fintech club in the United States

Agents should live where people already are

Photon is built around a simple belief: agents should live in the interfaces where people already are. For most people, that interface is iMessage - and the most useful thing an agent can do there is take real action, safely.

Flip is a clear example of what that unlocks: not a smarter calculator, but a financial assistant that understands plain English and executes across real accounts, with the user in control of every step. We're proud to be the iMessage layer behind it, and we're actively partnering with more founders and builders bringing agents to the channels people use every day.
