I was hired at @slashapp to refill the empty water cooler you can see on the left. Still haven’t done it. But I have spent the last few years working with founders, first as an investor at Soma Capital, Alpha Partners, and MS&AD Ventures, and now from the inside. One thing kept coming up over and over: Founders trust their bank. Until they don’t. Cards fail mid-spend. Payments get stuck. Support disappears right when it matters most. And then what? You’re trying to close customers, make payroll, move faster than everyone else, and suddenly one of the most basic parts of running the company becomes a blocker. I saw versions of that problem across a lot of companies. Different markets, different stages, different business models, same frustration: the financial tools around them were always a little too generic. That’s what I’m excited to work on at Slash. I’ll be focused on Startup GTM, which means taking a lot of what I loved about working with founders as an investor and applying it more directly: learning how they operate, where things break, what they actually need, and how Slash can be useful before those problems become painful. @victorcardenas and the team have built Slash with a very clear customer instinct. Spend time with the businesses, understand the workflows, and build around what they actually do every day. And on a personal note, getting to work with a Latino founder building at this level hits differently. There’s a shared context there that’s hard to explain, but easy to feel. Excited to be here. And very excited for what we’re building. PS: seriously, I’ll change the water cooler soon.

Is AI video at production quality yet? We asked @masonwarner, creative director at Slash: "Seedance 2.0 (ByteDance) is truly phenomenal." "I think it's at production quality. We've been using it for our last five major launches and advertisements." "Whatever production budgets I conceptualize in my head ($20,000-$100,000), I can do it for ~$1,000 to $2,000 of credits and 18 hours of just sitting on my computer."

As one of the newest members of the team, this was an amazing opportunity to learn more about Slash’s history and culture. If you’re looking for a new role in fintech I strongly suggest you apply!

Last week we took the whole Slash team to Hawaii for our annual offsite. We spent the week reflecting on the year, working closely within teams, and aligning on major projects for 2026 and beyond. A fun way to celebrate the hardest working team in fintech!

Mercury charges a 3% FX fee on card spend. An absurdly high fee. Yet it remains the dominant and default banking fintech for non-US founders. Why? From application and onboarding to payments, cards, treasury, integrations, support, and everything in between, Mercury has spent years building what is arguably the best founder experience in fintech. And product beats pricing. I've become intimately familiar with their product after helping hundreds of founders get access to it. Soon, I'll publish a deep dive that breaks down what Mercury gets right at every stage of the customer journey. And what any bank, fintech, or startup would need to do if they want to take the #1 spot.
