The majority of agentic interfaces are chat. The most rewarding part of this launch was how to design for control. Agents for finance can’t be “chat me the answer.” Finance is: 📄 policy → application → auditability → iteration. We designed our agent model around 3 ideas 👇

Starter: Done. ✅ Backing: $150bn strong. 💪 Main course: Served. 🍽️ We’re just getting started.

Today we announced the largest fintech-bank deal in history: our partnership with Capital One. In my five years at Brex, I’ve been focused on building our product and design orgs – shipping features, scaling teams, and connecting the systems that make it all work. That shapes how I see this moment. It comes back to a core belief that's guided how we build at Brex: the best roadmap is the one that compounds for customers. Every feature, every integration, every system is designed to solve real problems, not chase trends. Receipts that file themselves. Policies that auto enforce. Books that close in minutes. This partnership is validation of that approach. Capital One didn't join forces with Brex because of a pitch deck. They did it because of what we've shipped and how it works for customers. And now we get to bring our same high bar and roadmap to a dramatically larger scale. But what excites me most is what stays the same: our obsession with building exceptional products for the customers who depend on them. We're just getting started. brex.com/journal/brex-a…

We’re still discovering the best patterns for agentic interfaces and that’s the exciting part. Grateful for inspiration from @elou (Shape of AI is phenomenal) and @LukeW for pushing the conversation on AI design forward.

3. Every agent action has a citation. Not “trust me.” But: Here’s the policy I used, and here’s how I interpreted it. Autonomy is powerful. Traceability is what makes it usable. Citations are the backbone of how we give control to the finance team to improve their agents.

4,000+ AI companies now run on Brex, with the number of AI-native companies on Brex increasing 46% YoY. Brex is becoming the rails for AI spend.

Q3 ended on Friday at Brex, and it was our biggest quarter ever by a LOT. We have our biggest product release of the year coming tomorrow, and momentum continues to accelerate at scale: NRR of 120%+, NPS of 60+, all-time low churn. The customer experience is getting better and better every month. 🧵

We have some news. It drops tomorrow at 9am ET.

Founder Mode has also unleashed a wave of creativity and the highest-quality product-making I've seen in years @brexHQ . Because as the founder changes, the company changes too: We're focused on doing fewer things through a single roadmap. We've decoupled position and portfolio and operate more as an artist colony. There is only the artist and the work. We're funding real customer problems, not static, bottoms-up backlogs. And we've fallen in love with those problems, not the solutions. We co-design a clear vision to work backwards from, with real customers, rather than isolated in the abstract. We now move beyond org lines within Design, because there are no boundaries to a user. We're obsessed over not accepting good enough, unless it's extraordinary. We operate at all levels, regardless of role, from strategy to the smallest details, instead of delegating. We're focused on one thing: winning.

The new Brex mobile app was redesigned to be faster, more intuitive, and to help users manage spend with ease. 💪 💳 Want a behind-the-scenes look into the process? Check out our blog on how the new app came to life & the lessons learned along the way! ✍️ spr.ly/6014OC31m

On design, we have hit some major milestones at the end of last year. The team just grew past 40 in December and is going to almost be at 50 at the end of January. We have some very ambitious goals ahead, and I’m excited to see what the future holds.

Huge day at @brexhq today. I’m super excited to get to grow our product and evolve our team with Karan.

Can confirm working with @danhilltech is awesome 😃 Come join us @brexHQ !
