We have some big news to share: Composer has joined @SoFi — together, we're bringing automated trading strategies to millions more.

Since 2020, Composer has grown to a community of more than 175,000 investors and one of the largest sophisticated trading communities in the country. Six years later, we've made quant trading accessible to a generation of everyday investors.

Now we're taking everything we've built and going even bigger with SoFi.

SoFi runs one of the most comprehensive financial platforms in the country, used by millions of people for banking, lending, and investing. Pairing that reach with Composer's automated trading infrastructure, Trade with AI, and a community-built library of 2,000+ automated trading strategies accelerates our shared vision: helping people reach financial independence to realize their dreams.

What's next: We have rebranded as "Composer by SoFi". Soon, as Composer integrates further into SoFi, we'll start sharing what becomes possible for your trading. There's a lot to look forward to, stay tuned!

TLDR: Composer is joining forces with SoFi.

6 years ago this started as a white paper and a Slack channel between friends that sent trade alerts.

Today it's tens of thousands of users and billions in monthly trades.

Now with the backing of a fintech juggernaut, we can accelerate our goal of making intelligent trading accessible.

It was April 2020. Newly unemployed, as the world melted down from Covid. A visit to Nicaragua turned into a new home after the border was sealed.

So I did the only sensible thing: called up some buddies - Ronny, Ananda, Mikael and Anja - and we started an automated trading app.

Six years later, I am excited to announce @ComposerTrade's acquisition by SoFi!

@Calvary97 @benrollert Hey Jon - We are sorry to hear that! There is a new security feature that will automatically sign you out after 30 minutes of inactivity. This will only occur if you are inactive.

Please reach out to our team at [email protected], and we would be happy to assist you!

We set a new record for notional trading volume in March: $2.69 Billion. This is 66% higher than our previous monthly record.

So proud of the @ComposerTrade team - it takes a lot of blood, sweat and tears to handle this kind of volume - particularly with a 13 person team!

And no this isn’t an April fools joke, these are FACTS

[Benjamin P Rollert @benrollert]

record trading day for @ComposerTrade - $226M traded! That’s some size for a lil’ team!

Past performance is not indicative of future results, and investing involves risk, including the possible loss of principal. Review our full disclosures: https://t.co/vmCpXFiEPk

[Composer by SoFi @ComposerTrade]

No record is safe. $179M in trading volume today, our second highest day ever.

[Benjamin P Rollert @benrollert]

It's been a looooong time coming

Most systematic traders know this logic:

“If ANY of X, Y, Z is true, do something. If ALL of them are true, do something.”

It’s a fundamental building block for automated strategies. But painful to build without code, until now.

ANY/ALL conditions are now live on Composer.

One year ago, Moody Nashawaty and Risley Mabile launched Enders Capital, a quantitative hedge fund built with Composer. Twelve months later, the results are in.

Pending the final NAV print and today's data, the fund will have returned ~37% gross and ~33% net return to investors.

What does it actually look like to run a hedge fund on Composer, one year in?
