Today we launch USD Fiat Account for the world.

Companies in 100+ countries can now
- hold USD with a US sponsor banks
- pay US counterparties locally
- move money through direct access to the SWIFT with same-day settlement.

A company in Jakarta can pay a supplier in California for GPUs.

A Turkey company can pay a partner in Dubai for mineral fertilizers.

What used to take several banks and several days can now happen within hours.

Ai is RIP

[Kate Ivanova @ivanidze404]

Introducing my building an AI-native funeral company in public series.

Our generation does everything online and we care about experiences. But the one experience we’re all going to have? Still feels like a 100 years out of date.

Cringe.

The US has over 15,000 funeral homes. About 80% are family owned. Rising costs, staffing shortages, retiring owners. The people running these businesses are BURIED in admin while serving people in the toughest moments in our lives.

So where the hell does AI come in?

• Give owners one place to manage cases, staff, suppliers, and payments
• Help small teams serve more families by automating routine work
• Reach new customers through digital marketing and online booking
• Let families customize, plan and pay for a funeral online
• Expand the offering with pre-need plans, customized ceremonies and aftercare

Big-company infrastructure for small funeral homes.

Can we pull it off? The end goal: a personalized goodbye without the luxury price tag all over US.

Let's see!

Today, we’re launching USDT payments to China 🇨🇳

China accounts for ~30% of global manufacturing export, and for many importers, buying from Chinese suppliers is essential.

Now you can send USDT, and your supplier can receive a payment the same day through:

• Alipay
• WeChat Pay
• CIPS in CNH

For importers in emerging markets, this opens a faster way to pay suppliers without waiting on international bank transfers.

Pay in CNH at @hevn_finance

meet @mostik_ai!

what happens when you put 12 PhDs in one room for four months? first place on the ARC-AGI leaderboard, which I can't say much about while the competition is still running. and this, which I can.

everyone's arguing about whether open models will catch up to frontier models. we think it's the wrong question. here's the one we pose: why does a frontier model have to generate your answer at all, when the only thing you need from it is the reasoning?

we do this by enabling models to communicate in latent space. through our protocol, hidden states pass straight from a frontier model into a small one running on your infrastructure -- no text between them, and neither model is fine-tuned. two models from different families, sharing reasoning, both left untouched.

how do we know it works? we tested it on a setup where a 753B model reads the problem, and a 4B edge-class model writes the answer. with this approach, we get results 80% as accurate as the frontier model, but at 20x faster performance.

we're committed to preventing frontier model lock-in and are already partnering with inference providers to accelerate open-weight adoption. we've done this between 15 of us, in four months, 12 PhDs and a Fields medalist, backed by @generalcatalyst

LAUNCH: US Accounts for the world with the US Sponsor Banks.

If you run a company in Indonesia and need to pay a US supplier for GPUs, moving $500,000 should not take days of bank emails, paperwork, and uncertainty.

The same is true if you trade machinery, oil, LPG, food, or electronics across borders.

Today, we're launching US Accounts inside HEVN

Companies in 100+ countries can now hold USD with a US sponsor bank, pay US counterparties locally, and move money globally through direct access to the SWIFT with same-day settlement.

That means faster payments, fewer failed transfers, and far less friction in international trade.

A company in Jakarta can pay a supplier in California. A Turkey company can pay a partner in Dubai. What used to take several banks and several days can now happen within hours.

HEVN makes you enjoy payments.

Reading what AI doesn't say

(this topic genuinely matters to me, and it happens to be my birthday today, so if you feel like it, a repost would be a nice gift 🎂)

Something shifting in AI architecture that I don't think gets discussed enough through a safety lens. Models are starting to pass information to each other directly through internal representations, hidden states, activations, and computation vectors (still mostly research right now, but the infrastructure will follow). That matters for how we audit reasoning, since most of what we can currently check comes from what shows up in words.

Right now, the main tool we have for auditing AI reasoning is reading chain-of-thought. Korbak et al. (2025) spend a whole paper arguing this window is already "fragile" for single-model reasoning. If models start reasoning through vectors passed model-to-model instead of text, understanding that latent layer becomes the only way to keep any visibility into what's actually happening.

Thus I think that what seems underexplored is understanding the math of these latent spaces, and it might be the same research direction as learning how to monitor them.

Models appear to converge toward similar geometric structure regardless of architecture (Huh et al. 2024). If that's right, probes for safety-relevant features might generalize: deception patterns, goal representations, misalignment signals studied once and applied across models rather than re-derived per architecture.

Whether this holds for safety-critical features specifically is open, so is what adversarially robust latent decoding would even look like. Both feel more urgent than the current research investment suggests.

Send USD(C) from @hevn_finance with SWIFT. The math is simple:

UAE Bank (AED) ➜ SWIFT (USD) = 3% FX fees

UAE Bank ➜ HEVN ➜ SWIFT = 0.25% FX fees

Today was our last YC office hour.

These past 8 weeks have been incredible. Some of the most intense, educational, and bonding weeks of my life.

I'm so bullish on everyone in this photo! GMI! 🚀

@ycombinator @raspire_ Congrats! 🌟

Today, Paul Graham joined our final YC event before Demo Day.

For me, PG is a true living legend. I was reading his essays in high school and watching his Stanford lectures, and they were a major inspiration for me to drop out of collage and move to San Francisco five years ago when I was 20.

Thank you for everything you have done.

Security is one of the two fundamental barriers to the adoption of AI payroll. We're now one step closer to solving it.

Two weeks ago, we launched @hevn_finance CLI.

Today, more than 75% of transactions and 6/10 invoices at HEVN, inc. are executed through agents and APIs.

In this update, we introduce HEVN Apps - isolated subaccounts with customizable permissions and spending limits for your agents:

⛨ Every "hevn login" grants access not to the entire account, but only to a specific internal application.

⛨ HEVN allows you to create renewable daily spending limits for each app.
You can restrict access to every feature individually, including global bank accounts and payroll operations.

⛨ Notifications and automatic API key revocation if we detect unusual behavior, abuse, or spam.

Automate you global transactions with HEVN on gethevn(.)com
