Stoaexchange
Hi HN, we’re Eren, Berat and Kaan. We’re building Stoa (https://www.stoaexchange.com), a marketplace for new and used GPUs and AI servers. GPUs are the collateral in the data center buildout. Today, financing terms mostly depend on the offtaker, meaning the company that has committed to use the compute. If that company is a hyperscaler, the financing can look investment grade. If it’s a smaller cloud or startup, terms get expensive fast, even with the same hardware as collateral. The lender’s problem is pretty reasonable. If the borrower defaults and we need to sell these servers, what can we actually get for them? There isn’t a good answer today. We started brokering GPU deals to understand why. It was much more manual than we expected. The hardware is still traded through phone calls, forwarded spreadsheets and long email threads. One week, a seller quoted us $200k for a server node and another quoted $240k for what looked like the same thing. Neither was necessarily wrong. They had different information and could only see their own corner of the market. Before we could compare the quotes, we had to sort out the configuration, condition, warranty, location and delivery terms. It’s the same information Kelley Blue Book attaches to a used-car price through the year, trim, mileage and condition. “An H100 server” isn’t enough information to know what something is worth, just as “a used BMW” isn’t. This is also just a bad way to buy or sell hardware. A buyer looking for the best price shouldn’t have to contact several brokers and dealers separately, repeat the same request and then untangle a pile of different quotes. Sellers shouldn’t have to search for demand one buyer at a time. A market of this size deserves better liquidity. Stoa puts the request into one format and sends it to dealers that have gone through know-your-business (KYB) checks. We verify the company, who owns it and who is allowed to trade for it. Before the request goes out, the buyer confirms the exact configuration, quantity, condition, warranty, location, delivery terms and what will be checked during inspection. Dealers return firm quotes against that same request without seeing each other’s bids. Once a quote is accepted, payment, shipping, delivery and inspection are then tracked through settlement. We don’t take possession of the hardware. We got more than $300M in requests for quotes (RFQs) during our first month. The immediate goal is to make buying and selling this hardware less painful. As trades build up, they also leave lenders with actual resale evidence instead of list prices and one off appraisals. We knew from the beginning that this couldn’t be a software only marketplace. GPU trading runs on relationships, and inventory isn’t shown to just anyone. Dealers need to trust the people bringing them clients, and clients need to trust that quotes will actually turn into trades. We built those relationships over time by brokering deals ourselves. Stoa gives people a cleaner way to trade, from the first RFQ through settlement, but it doesn’t replace the trust underneath. Those relationships, and the history of who actually follows through, are a big part of our process. We’ve known each other for more than ten years. We have founded companies, traded interest rate derivatives, built trading and pricing systems for oil and gas. We learned GPU trading by doing the deals ourselves, and Stoa grew out of the problems we kept running into. We charge a tiered fee on completed trades, with lower fees at higher volumes. It’s free to sign up at https://www.stoaexchange.com/signup. If you’ve bought, sold, financed or had to liquidate GPUs, would be great to hear your take!
Orate
Hey friends! Brad here - long time HN user, founder, engineer (Coinbase, Soothe, Jeevz, Release, Hired, GrowthX, etc)... I have been struggling recently with too many tabs, emails, articles, etc sitting unread while I swap between Claude code sessions all day. So I decided to build Orate to help me work through the backlog by listening to it all like I would a podcast. Orate allows you to select any text on your screen and keyboard shortcut it to a listening queue where it gets processed using the latest + greatest TTS AI models, and then read back to you in a mostly-natural sounding voice. Orate works fully on-device and offline. Whatever you pass to it stays yours. It's native, lives in your menu bar, and supports things like tagging, system playback controls, speed adjustment, and more. There's also an optional HD-voice tier that uses Chatterbox instead of Kokoro which ships with it for more expressive TTS. I'm also burnt out on being chipped away at little by little with a subscription for everything, so it's just $4.99 one time and you own it forever. Use the code HACKERNEWS for $3 off, putting you at just $1.99. As AI helped me nail down - it's "read it later, for your ears". I hope you like it! If you have any questions, want more details, notice any bugs, or have an idea for something cool to add, just ping me! I plan to launch a companion iOS app soon to sync text between your devices as well. It's currently Mac only, but I might whip up a Windows version if the response is good. Cheers!
Ekko
Hi everyone, I am a big privacy activist and the amount of privacy concerns in the internet with the discussions around European Chat Control, Meta removing e2ee in Instagram and corporations harvesting personal data for AI training is on the rise. The closed source social media companies keep managing and storing our private keys, allowing them to effectively access all of our personal communications.. Many open source alternatives exist, but the problem I kept running into was not a lack of good private messengers. Signal, SimpleX, and other projects already do important work The problem was getting the people to move. A messenger is only useful when the person you need to reach is there. Asking friends, family, coworkers, or customers to abandon their existing chats is a very high barrier. Ekko takes a different approach. It runs as a browser extension on top of existing messengers. Both people still need Ekko, but they do not need to move their conversation. You can continue using the Instagram, WhatsApp, Telegram, or Messenger chat they already share. Actively building this and trying to achieve a seamless automatic encryption in the UI across all popular messengers and adding support across all browsers, IOS, android and social media.. Under the hood, Ekko uses hybrid X25519 + ML-KEM-768 and XChaCha20-Poly1305. Private keys are generated and kept on your device. You can claim an Ekko handle to make exchanging public keys easier, exchange invitations directly without an account, or self-host the public-key directory. Currently: - A Chromium browser extension, Experimental Firefox and Safari builds - Instagram, WhatsApp Web, Telegram Web, and Messenger integrations - A self-hostable key directory - Open-source client, protocol, and server code Early version Chrome Web Store: https://chromewebstore.google.com/detail/ekko/oaihgpmbkeafbp... Source code: https://github.com/useekko/ekko-core Website and demo: https://useekko.app I would genuinely appreciate direct feedback especially from people familiar with applied cryptography, browser security, key verification, messenger integrations, potential solutions for iOS UI integration (faster than using browser w/ Safari extension) If you try it, please tell me what breaks or what feels confusing. Actively trying to make this better as a side project! If you discover a security issue, email kirill@useekko.app rather than posting it publicly. Looking for feedback! :)

Scott Pelley Shows How Legacy Media Got It Wrong – and Bari Weiss Made It Worse
A platform to find people to jam on side projects with
I have always found it funny how challenging it can be to find people to jam on side projects with. There are literally entire sub-Reddits where people post looking for someone to work on a project with. That is super inefficient. There are also newsletters for this (also pretty inefficient). Let's Jam is my attempt to solve this. This is NOT a cofounder matching platform. The idea is to connect people with ideas and skills so they can jam on them together. If they end up becoming cofounders, cool, but that is up to them. This is also NOT a place for freelancers to hunt job opportunities. Again, the platform is for people who have an idea or a skill and want to work on something together. How it works: > You either a) find a project and request to jam on it with that person, b) post a project and wait for someone to request to jam on it with you, c) claim an idea and wait for someone to request to jam on it with you. > Once someone requests to jam with you, you'll get an email, and you can vet them via LinkedIn or their past work. If you think they'll be a good fit then accept their request and they'll reach out to you. > That's it. Simple. Any feedback is greatly appreciated!

I built a frontpage for personal blogs
With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
