BlindPay has received approval for its first U.S. state Money Transmitter License (MTL). With 25 MTL applications submitted across the United States, this marks an important step in our long-term U.S. expansion. Compliance has been part of our foundation from day one. This approval reflects months of preparation, regulatory engagement, and work across our team to build trusted global payment infrastructure. Our focus now is on progressing the remaining applications and continuing to strengthen our compliance program as we grow.

Today we're introducing Payables. Let your business pay invoices and bills directly from stablecoins. Upload an invoice, boleto, Pix codes, utility bill or tax bill. We extracts the amount, beneficiary and due date, then routes the payment through the right local rail.

we’ve been visiting some @BlindPay customers in Paraguay this week first time here you can read about a market all day but actually being here and seeing how money moves makes a huge difference people are buying products with: > USDT > Pix > Guaraní > US Dollars with multiple currencies accepted in the same store Paraguay has become a major commerce and redistribution hub for the region, especially for Brazil the country imported almost $17B worth of goods in 2025 and you can actually feel that scale on the ground it honestly feels like a mini New York for Latin America (this photo looks like Times Square lol) there’s advertising everywhere, stores packed at 8am and people from all over Latin America buying products and there are almost two different worlds here: > smaller local stores > huge shopping centers with global luxury brands there’s basically something for every kind of customer seeing this in person changes how you think about building financial infrastructure for Latin America really excited for the next chapters here!

should we create a BlindPay Developer Associate program? customers keep asking us: “do you know any developers who can help integrate BlindPay?” and we almost always recommend the same developer he’s integrated BlindPay for multiple customers, knows the API extremely well and constantly gives us feedback on how to improve the DX this is already happening organically, so the idea is simple: > train developers on BlindPay > certify the ones who know the product deeply > connect them with customers > let them make money from our ecosystem we also just hired an AI engineer who built a working neobank on top of BlindPay in only 3 prompts we’re now improving the docs for a world where both developers and agents should be able to go from idea to working financial product as fast as possible the best developer ecosystems create value for everyone building on top of them

we’ve been working on a complete redesign of @BlindPay for the past few weeks there are 3 main reasons why > a lot of what we built made sense for who we were in 2024 our first brand, copy, website, skeuomorphism style, the visual language, all of it reflected what we were building at the beginning but BlindPay is a very different company today > the brand no longer reflects what we want to build over the next 10 years we’re building something much bigger than what we started with and the brand needs to represent where we’re going, not where we came from > design is becoming way too easy to copy we’ve already seen competitors copy parts of what we built and now with AI, almost anything can be recreated in minutes so this time we want to build something completely different a visual language that feels uniquely ours a visual identity and website with so much craft, detail and personality that they become much harder to copy AI is making it easier for everyone to build the same things we want to go in the opposite direction we also teamed up with two incredible creatives to help bring this new version of to life

I recently saw a neobank founder posting about how to "bypass" bank account compliance program I’ve seen hundreds of fintechs die because of fraud and it reminded me of something that happened to us during YC @BlindPay was scaling when we faced our first fraud attempt that was the moment i realized compliance needed to become a much bigger priority for us I’m not a compliance guy but since then, i’ve spent a lot of time studying: >regulation >risk >controls >AML >fraud not because i wanted to become a compliance expert but because if you’re building a company that moves money, you need to understand the risks that come with it learning this early was one of the most important things that allowed BlindPay to scale safely today at BlindPay: >KYC is completed within 30 minutes >KYB is completed within 1 day >our average KYB review is 21 hours and we’re now working to bring that down to 8 hours compliance doesn’t slow down a fintech weak compliance does the goal isn’t to remove compliance so you can move faster it’s to build compliance so well that you can move fast without putting the entire operation at risk

For a longe time our burn rate was related to compliance/regulatory Now we're spending more on design than ever Stay tuned cc @ericvna @0xGusta @LuisBizarro
My hottest take is that brand marketing is going to be THE major differentiator and one of the most prized assets for a company going forward. And, I’m not talking about launch videos or pouring money primarily for “aesthetics” simply to pump the valuation. You still need retention before attention. I’m talking about thinking through what a company stands for and understanding the “vibe” of what’s happening in the market. Being relentless on the long term goal while also thinking through how to showcase the company in the short term. And doing it every week. Especially if you think agents become the primary user for most products, then to get the attention of a rapidly attention deficit audience (aka humans) you’ll need to stand out consistently in how you present the company. These folks primary have been given tier 2 roles and passed up for CMOs many many times. I think this will finally invert in the next 10 years where you’ll hire these folks as cofounders or at least give them a big seat at the table. Normally the design centric CEO tends to be this, but those are rare and you’ll need to learn how to hire for this role. Just like a good product marketer, these are exceptionally rare so you have one hold them close!!
