A big milestone for @mercury today as we announced our Series C led by @sequoia. Excited to have the support of @sonyatweetybird and some of the best VCs as we bring our vision of banking* that does more to life.

[Mercury @mercury]

Introducing Command from @mercury

Command is a new agentic operating system for banking - frontier AI paired w/ mercury’s UX, tools, and knowledge to turn ideas into action

It's available today to everyone on Mercury, business and personal (and iOS)

Why'd we build Command? 🧵

[Rachel Moncton @Rachel_Moncton]

Agentic banking only works if there's trust. We built trust into Command (approvals, source data); but we've also spent years earning the trust to launch this. Trust comes from how we communicate, what we ship, how we handle hard times. Trust is the foundation of our brand.

[Mercury @mercury]

Mercury Command is live.

AI built directly into your Mercury account that completes financial work. Natural language, real actions, and you approve everything.

This is how banking* works now.

[Rachel Moncton @Rachel_Moncton]

@mercury what a milestone! excited for mercury's next chapter

[Rachel Moncton @Rachel_Moncton]

AI is going to enable more founders in the next 5 years than we saw in the last 20. Legacy banking isn't built to serve them — and the US is behind on fintech adoption.

Mercury is going to change that. Excited for the next chapter.

Mercury is the single “product” that has improved my life the most. I have always hated banks, invoicing platforms, and corporate cards. They make all of these things so incredibly easy. I haven’t had to open QuickBooks in over a year now.

They do not pay me. I am genuinely just this hyped on them. The only catch is that you’ll hate every bank you use after trying Mercury.

If you need a “bank” for your business, I can’t recommend Mercury highly enough.

[Rachel Moncton @Rachel_Moncton]

This launch came together in a matter of days. Gone are the 6 - 8 week launch timelines. AI is collapsing product timelines and marketers have to adapt: sit w the engineers, pick 2 priority channels, iterate as you go.

[Mercury @mercury]

Our developer suite just got a new addition: Mercury CLI.

[immad @immad]

1/ Today @Mercury received conditional approval from the OCC to establish Mercury Bank, N.A.

I started Mercury in 2017 to build the bank I wish had existed as a founder. Nearly a decade later, we’re getting there.

@mercury @sxsw can't wait to check out these spots when i'm in austin in a few weeks!

4/ It is a risk to do something different and it requires trusting your brand, as well as trusting your customers to notice and care. I'm proud of the work. More to come soon -- but first look in the video above.

[Rachel Moncton @Rachel_Moncton]

1/ Most fintech marketing looks the same: product shot, feature list, and some variation of "your new financial operating system." We wanted none of that.

Here's some of the why behind the campaign:

[Mercury @mercury]

Better together 🤝 Mercury Personal is now included with Mercury Business.

*Mercury is a fintech company, not an FDIC-insured bank. Banking services provided through Choice Financial Group and Column N.A., Members FDIC.

[Rachel Moncton @Rachel_Moncton]

3/ Work and personal aren't separate modes for our customers.

So the campaign doesn't lead with features or the promo. It treats our customers as people with full lives, real ambitions, and taste. They aren't just founders who appreciate free wires and savings yield.

[Rachel Moncton @Rachel_Moncton]

A marketing lesson from 2025: personalization is easy to overdo.

As @Mercury reached more businesses it was tempting to segment everything — more personas, landing pages, “custom” messaging, etc.

But it didn’t always perform better.

@Immad goes deeper in his annual letter.

1/ Mercury 2025 Annual Letter

@Mercury 2025 stats:
* 50% YoY growth in customers to 300k
* 59% YoY growth in transaction volume to $248bn

The theme of the year was expanding beyond startups: we saw 73% of new customers came from outside AI or tech startup category

🧵

[Rachel Moncton @Rachel_Moncton]

@mercury started out fun and then got a little too real. happy halloween!

[Rachel Moncton @Rachel_Moncton]

@mercury’s latest data report is out. The takeaway? Early stage founders — especially those who have adopted AI — are optimistic about the future and optimizing for growth. Excited to support them.

[Mercury @mercury]

Startups in 2025 aren’t waiting for the economy to calm down.

They’re finding new ways to grow — right now. 📈

We surveyed 1,500 early-stage companies to see how they’re raising, spending, and hiring.

Here’s what’s changing and what it means for the new economics of starting up 🧵

[Fast Company @FastCompany]

Pew says half of U.S. workers fear AI replacement. But a survey of 1,500 founders shows AI adopters are growing their teams, not shrinking them. https://t.co/xa4p1bot4P

[Rachel Moncton @Rachel_Moncton]

Always great to look back on the year (especially if you're at a fast-moving startup). Proud of the steps we took towards our ultimate vision of a bank account* that can do more. In 5 years, we'll all be thinking differently about banking.

[immad @immad]

1/ Mercury 2025 Annual Letter:

Our vision is that banking* should do more than hold your money. It should include the cards and software you need to actually use your money.

In 2024, we took huge strides to bring that vision to life:
* Grew transaction volume to $156bn.
* Launched 4 new major products – bill pay, invoicing, accounting automations and expense mgmt
* Expanded into the consumer space with Mercury Personal*
* Invested in our core banking infrastructure and experience

Here’s how we got here and what we learned along the way 🧵
