Proud to announce that SalesPatriot raised $5M seed to modernize defense procurement. Our AI-driven platform cuts order processing 7x faster, powering $200M+ Pentagon orders. If you want to build mission-critical systems while helping protect the west, join us.

@kozerafilip congrats!!

Proactive agent that thinks and acts like you. Multiplayer AI Brain for teams. Proper GUI for commanding 50 agents. Sauna.ai is all three. Sauna goes live today. First 2000 people, use access code LAUNCH for $80 of weekly(!) credits. Let’s explain. Multiplayer only works once the personal brain is powerful. So let's start here. Personal AI Brain 3,800+ tools connected. State of the Art memory. Skills and schedules you teach once that get repeated forever on cheaper models. An AI first CRM. Lives on the cloud so you can initiate tasks from anywhere: iMessage, Slack, Email. Also no need for a Mac mini 😉 GUI AI agents have been stuck in their MS-DOS era. A chat box, a scroll buffer, no way to command 50 of them. We built the first GUI: Live sessions on one side, work waiting for your sign-off on the other, plus the things Sauna kicked off while you were asleep waiting for review. Game mode helps clear the queue with actual joy. Okay so far so good, but how to give benefit of what you built to more people or whole team? Multiplayer Once your Sauna actually knows you and you gave her access to your tools, you can use multiplayer. Two modes: - Brain access. My co-founder Robert plugged my brain as a tool into his Sauna last month. He can ask it about pricing while I'm in other meetings, gets a sourced answer back, never has to interrupt me. That’s read only. Yolo mode gives him access to all my tools too :O - Communal Saunas extend that to whole companies with proper permissioning. Folder owners decide what's true for the whole company and build skills. Most get their personal brain + read access to communal files and memories. Works also for group planning my best friend's bachelor party. The Way I’ve been obsessed about AI Brain since 2016. Our human brains suck at some things like memory and are brilliant at others like creativity. We are also particularly bad at thinking we are all on the same page and then realising weeks later that we weren’t. Most leaders spend their days being the human diff tool, catching contradictions in hallway conversations and Slack threads. Repeating themselves 50 times. Now every company is spinning up hundreds or thousands of agents that drift faster than humans do, feeding each other their drift as context. Compounding rot. After 10 years and one failed company in this space we are launching the solution. The Launch We thought about a celebrity launch. Margot Robbie in a bathtub explaining agents. But then we realised the same money gives the first 2,000 people free daily credits, every day, until we burn through that $1,000,000. Sauna runs Claude, GPT-5, Gemini, GLM-5.1, DeepSeek, Kimi so you can budget yourself. The labs are racing to lock you so they can milk you in a year. We picked your side. Onboarding It’s live at app.sauna.ai We’ve preheated saunas based on a niche. Use the access codes in the comments to get a better experience.

@piotrek_nowy mega!!

Obserwujemy dziś jeden z najtrudniejszych momentów na rynku pracy ostatnich lat. Mamy więcej kandydatów, rosnącą konkurencję i procesy, które często są dłuższe i coraz bardziej stresujące. Od 8 lat razem z zespołem rozwijamy dla Was justjoin.it i rocketjobs.pl. W tym czasie pomogliśmy wielu ludziom znaleźć pracę. Ale od dawna chcieliśmy zrobić coś więcej. Dlatego po miesiącach pracy dziś wychodzimy z piwnicy i na świat wypuszczamy Rocketa - Twojego asystenta kariery w formie aplikacji mobilnej. 🚀 To pierwsza taka appka na polskim rynku, która naprawdę pomaga dostać pracę, a nie tylko znaleźć fajne ogłoszenie o pracę. Wcześniej kandydat musiał radzić sobie przed rekrutacją sam, z naszą aplikacją ma „supermoce” w kieszeni. Co konkretnie daje Ci Rocket: ✅ 1. Masz dostęp do dziesiątek tysięcy oferty pracy z całego rynku ✅ 2. Stworzysz CV do każdego ogłoszenia z poziomu smartfona ✅ 3. Sprawdzisz opinie o firmie w sieci, do której aplikujesz ✅ 4. Rocket sprawnie pomoże wypełnić formularze aplikacyjne ✅ 5. Przygotujesz się wspólne z Rocketem do rozmowy rekrutacyjnej ✅ 6. Masz pełną wiedzę o zarobkach na rynku = Masz własnego asystenta kariery w kieszeni. Wszystko z poziomu Twojego smartfona. Jak to działa? 1. Pobierasz aplikację z App Store lub Google Play 2. Logujesz się (najlepiej) przez LinkedIn 3. Rocket w kilka sekund tworzy Twój profil zawodowy, 4. Prowadzi Cię krok po kroku - od wyszukiwania do zdobycia pracy. To dopiero MVP, pierwsza wersja appki, która będzie tylko lepsza. Wiele rzeczy jeszcze poprawiamy, niektóre dopiero testujemy. Nie wszystko będzie działać idealnie, ale i tak będę wdzięczny za podanie tej wieści dalej w świat, niech się niesie! 😇 Daj też znać, co działa, co nie działa i co możemy zrobić lepiej! :) Każdy komentarz, bug report i feedback to dla nas złoto! :) ➡️ Android sklep:  play.google.com/store/apps/det… ➡️ iOS sklep apps.apple.com/pl/app/rocket/… Pobierz Rocketa 🚀 - pierwszą appkę, która naprawdę pomaga dostać pracę!

To już w sumie wiedza powszechna, że eksport z Europy do Rosji odbywa się między innymi przez Kirgistan (głównie automotive). Można coś z tym zrobić, a można palić głupa. Polska i Litwa przykładem dla Niemiec i Włoch, które mają solidarność w walce z Rosją gdzieś…

CMMC is sweeping through A&D. We don’t touch controlled data, only public info and yet still deliver strong signals and compliance-aligned workflows.

@AJamesMcCarthy woah you took this?? looks like Ai but so cool!

Still can’t believe I got this shot… I’m going for something even more difficult this weekend, wish me luck 🙃

@shaunmmaguire That looks so good

Dear Haters and Losers, Don’t forget that my wife is Persian

@rohanpaul_ai Why would someone have this in their house lol

Even an $80K robot has lots of breaking points, and so does the AI running it. we have a long way to go before they can become our room-mate.

@IEAmbPoland Nice view

Brilliant to see blue skies in Warsaw in November.

@Turbinetraveler Cool!

Raccoon eyes on the Airbus A350.

@BLackgold_5 a dream

Describe this view.

@growing_daniel Cool but looks random since there are no other larger buildings next to it

I love that they built this thing. Every city should have one. Just so they can say they did it

@JonBbC_TechGeek lol!

These are the coolest mugs ever!

@MCCCANM Not to mention all the horror stories about air bnbs I've heard I think I can last a day in one. Hotel all the way

I infinitely prefer a hotel to an Airbnb, even if I have to get two rooms.

@doganuraldesign Thats so cool

Grok is beautiful Text-to-image just got a massive upgrade! Go check it out, you'll be surprised Grok image + Grok video

@BoyanSlat @TheOceanCleanup wow

So far in 2025, @TheOceanCleanup has been collecting an average of 3200 kg of trash for every hour of the year.

@Kamscan diesel in the lake?

Sounds like it is here ,semi is leaking diesel. Not sure if it's the saddle tanks

#Kamloops crews responding to a semi crash carrying dangerous goods . Sounds like at the Highway 5 (Coquihalla)and Highway 1 junction ,no other details

@georgecursor @dividendology idk you tell me

@dividendology The money is now worth less than toilet paper, mate. What recovery are you talking about?

I just realized this. Today is officially the first day Bank of America stock has fully recovered from the Global Financial Crisis. Wow.

@ceanmedia Amaznig

@NoMansSky lol

every other publisher right now
