A scientist in Denmark figured out how to make Claude prepare his job applications. He open-sourced the whole thing.
His name is Mads Lorentzen. He is a PhD geophysicist. He built it on top of Claude Code and released it under MIT license.
Here is what it does. You fork the repo, fill in your background once, and it runs a five-step pipeline for every job you want to apply to.
Step 1. It reads the job posting and scores how well you fit.
Step 2. It drafts a tailored CV in LaTeX, picking only the experience that matches.
Step 3. It writes a cover letter framed around what you would bring to the role.
Step 4. A second AI agent reviews the first agent's work, points out weaknesses, and the first agent revises.
Step 5. It compiles both into clean PDFs you can send.
The whole thing is a folder of markdown files. The candidate profile, the writing style rules, the CV templates, the interview prep notes. Every step is plain text you can read and change.
The job portal search is built for Danish boards. The application workflow itself works for any country.
489 stars. 270 forks. A fork-to-star ratio that high means people are using it, not only bookmarking.
Mads is not a startup founder. He built this because he needed it for himself, then shared it.
This is the future of job hunting. Not a service you pay for. A workflow you own.

I spoke with a member of the technical staff at Anthropic yesterday who is about to make $17 million.
He's been there less than 2.5 years and is blown away by his equity value. His biggest worry now is tax strategy.
His CPA told him to "max out his 401(k) and consider a donor-advised fund."
While that's a great starting point, here's what makes even more sense:
He's acquiring a 48 unit apartment complex in Phoenix for $14.5 million.
We're running a cost segregation study to reclassify approximately 30% of the depreciable basis into 5, 7, and 15 year property.
Here's the math:
• $14.5M purchase price
• ~$12.3M depreciable basis (excluding land)
• ~$3.7M reclassified to short-life assets via cost seg
• 100% bonus depreciation under OBBBA = $3.7M accelerated to Year 1
Plus standard Year 1 depreciation on the remaining basis adds another ~$315K.
Total Year 1 deduction: approximately 4M.
His wife is qualifying as a real estate professional 750+ hours, more time than any other activity. The loss is no longer passive. It offsets ordinary income.
At a 37% federal bracket plus 13.3% California, that's a combined rate just over 50%.
$4M × 50% = 2M+ in tax savings. Year 1.
Layer in operating expenses, loan interest, and startup costs on the property, the total offset against his Anthropic income crosses $3 million.
Not deferred. Not spread over 27.5 years.
Meanwhile, the property cash flows. He's converted concentrated tech stock into a real asset producing monthly income. And he's done it all before he files the return on his equity windfall.
This is what real tax planning looks like for tech liquidity.
If you're an engineer, exec, or early employee sitting on a meaningful equity position and your CPA hasn't mentioned cost segregation, bonus depreciation, or REPS qualification, you're probably leaving seven figures on the table.
THIS GUY LIVES UNDER SFO'S TAKEOFF PATH SO HE BUILT A CEILING PROJECTOR THAT TRACKS EVERY PLANE FLYING OVER HIS HOUSE IN REAL TIME
he uses a cheap $30 radio receiver to pick up the signals that planes broadcast while flying.
then projects them onto his ceiling in real time
when a jet flies over his house you hear it outside and at the exact same moment a plane glides across his ceiling labeled with the airline, aircraft type, and destination
pure black background so the projector's rectangle disappears and only the aircraft are visible
but he didn't stop at planes
it also draws the real sky behind them. sun, moon, bright stars, constellations, and live satellites including the ISS. all at their true positions for his exact location and time in real time
so he's lying in bed watching the actual night sky projected onto his ceiling with real planes crossing through it as they take off from SFO
there is a huge market for every man alive that runs outside to see the helicopter
vibe coded the whole thing himself with a cheap radio, a projector, and some clever software
Jensen Huang says that investing in the IPOs of SpaceX, Anthropic, and OpenAI will be like buying $AMZN, $GOOGL, or $META in their early stages.
Don't become a victim of FOMO.
IPO day is not where the best opportunities are made.
In many cases, there's a massive spike followed by a sharp decline that takes the stock below its IPO price.
Just look at $META.
After its 2012 IPO, the stock lost more than 50% of its value within three months.
The best opportunities come when the hype is gone, sentiment turns negative, and nobody wants to touch the stock.
That's when I'll be buying heavy.
Conan O'Brien used his Harvard University commencement speech to argue that humility and the human connection matter far more than any diploma.
"I always recognize the enormous role of luck in my life. Refusing to see how luck has played a role in anyone's success is simply ignorant. Many people are happy to mistake a lucky poker hand for their own brilliance, and fighting that human instinct has kept me sane.
"I honestly believe that community, spontaneity, and a real commitment to humility has helped me build a rich life that means much more to me than any diploma. And believe me, I'm not saying the goal is to renounce accomplishments, but rather to metabolize them. If you carry your victories lightly, other qualities –- kindness, originality, courage, humor, and humanity –- have room to emerge.
"Maybe the greatest lessons I've learned along these lines have been through my 24 travel shows. I have degraded myself in Cuba, Ghana, Korea, Armenia, half of Europe, Argentina, Thailand, Mexico, and Greenland, where I visited a real estate office and tried to buy the country. When I travel to another land, every quality I have discussed -- community, adaptation, and a sincerely humble approach -- are all necessary. When you don't speak the language, no one truly cares where you went to college, and you have no choice but to make friends.
"It's on these travels that I learned a great lesson: let yourself be bad at things. I have been a bad dancer in every country I have visited. But the people laugh because it turns out everyone everywhere is related to at least one terrible dancer. For me, humility on these trips can easily lead to humiliation, which is also a useful tool.
"Three weeks ago, I visited Amsterdam, dressed up as Van Gogh, and forced my way into the Van Gogh Museum, where I started loudly demanding a cut of the merchandising because I made no money during my lifetime. Guards forcibly ejected me. I was roundly mocked by patrons for my pathetic display. But I did see a lot of smiles. And not one person said, now that's a Harvard grad.
"In Tokyo, I met with a teacher of Japanese etiquette who volunteered I wasn't her type. And when I asked her why, she just said, 'face.' In Ghana, after accepting a royal invitation, I was kicked out of the Ashanti Palace by the Queen Mother, because her favorite soap opera was starting.
"I understand that I am preaching modesty and connection at a time when this is not in style. We are living through a period of extreme narcissism. Our current leadership in Washington believes that empathy is a weakness and that our nation stands supreme and alone. Add to that, everyone here today has a phone in their pocket that is algorithmically programmed to celebrate you and you alone by making you the protein-maxing hero of your own special journey.
"Much has been written about how isolated and siloed we've become, but for me, the antidote is quite simple. By de-emphasizing what makes us special — in your case, a prized degree — we can really find one another, not as an exercise in virtue, but as a path towards greater laughter, love, and real growth."
Nvidia will now pay you to put a mini AI data center on your house
It looks like a normal AC unit in the yard.
But inside sits 16 Nvidia Blackwell GPUs and Dell servers.
A startup called Span builds them, backed by Nvidia.
They bolt onto your home and you get paid for the power and Wi-Fi.
Some estimates put that around $1,000 a month in your pocket.
That is rent money just for hosting a box outside.
Span says it deploys way faster and cheaper than a real data center.
The AI boom is literally moving into the suburbs.
Save this, the grid is getting rebuilt in real time.
A company gave every employee unlimited access to Claude.
Set zero spending limits.
Got a $500 million bill. In one month.
Meanwhile Meta made token usage a leaderboard.
Low score meant getting fired.
So engineers left AI agents running all day doing nothing.
Just to keep their jobs.
AI was supposed to replace the humans.
Instead the humans figured out how to game the AI metrics.
Nobody is getting replaced. Everybody is just bleeding money.

who else did I miss?
I just got back from SF and I FEEL INSPIRED.
I spent 5 days with frontier AI model teams, AI startup founders, and 3 billionaires.
My takeaways:
1. I had lunch with 3 billionaires. All of them are buying SaaS companies and rebuilding them agent-first. They were deeply inspired by Bending Spoons and Ryan Cohen's eBay deal. Buy the company, cut the headcount, rebuild the tech, add agents, add features, make more valuable experience, raise prices.
2. The frontier model companies are hungry for usage data from the field. They can see API calls and token counts. They can't see the actual workflows. If you're deep in a niche using these models in ways the model companies haven't seen, that understanding is incredibly valuable. Usage intelligence is the new alpha.
3. Consumer AI is massively underbuilt. Every billboard in SF is either B2B inference infrastructure or vertical agent companies. The entire city is optimized for enterprise. Meanwhile you have companies like Cal AI doing $50M ARR in 18 months as a consumer app. I met with a cool few teams doing consumer AI (@paulscherer / @ekuyda)
4. MCP came up in literally every conversation. The companies exposing their product as MCP endpoints are getting pulled into deals they never pitched for. The ones that aren't are becoming invisible to agents. This is the new SEO. If agents can't find you, you don't exist. Building products for agents is the new zeitgeist in general.
5. Not uncommon for hot seed rounds to be $25-50 million valuations. I saw a Series A at $450 million
6. If I had a dollar every time someone mentioned "forward-deployed engineer" this trip I could have funded a seed round. It's the hottest role in SF right now. The person who sits between the agent and the customer, making sure everything actually works.
7. The mood around open source shifted. A year ago it felt like open source was chasing the frontier models. Now founders are telling me Gemma and DeepSeek are good enough for 80% of what they need at a fraction of the cost. The "which model do you use" conversation is being replaced by "which model for which task." Model loyalty kinda feels dead.
8. Voice agents came up more than I expected. Multiple founders told me voice is the interface for the next billion users. The billion people who will never type a prompt will absolutely talk to one.
9. The Obsidian community in SF is weirdly intense. Multiple founders showed me their vaults unprompted. Like showing someone your home gym. It's a flex now. The quality of your knowledge base (second brain?) is becoming a status symbol among builders.
10. Maybe it was just the people I met but the age of the founders is shifting. I met more founders over 40 this trip than any trip before and more founders under age 21 than ever before. Founders getting older and younger at the same time.
11. I spoke to a lot of fast-growing startups, VCs and frontier models who are hiring content creators right now.
12. The restaurant scene in SF is actually better than it's been in years. Founders are going out more. Alcohol is out, not surprisingly.
13. SF doesn't feel like the only place anymore. We all have access to the same frontier models. We all read the same X feed. A founder in NYC or Lagos is calling the same APIs as a founder in SoMa. So in the past it felt like SF was always lightyears ahead, doesn't feel that way anymore. It's okay not to live in SF and have BIG DREAMS.
14. The coworking spaces in SF are half empty but the coffee shops are packed. People want to be around people. I had a few startup ideas here....
15. Walking around the Mission I noticed something: the street-level businesses, the taquerias, the barbershops, the laundromats, none of them use any AI at all.
16. I heard the phrase "agent debt" for the first time. Like technical debt but for agents. When you hack together an agent workflow fast and never clean it up, the system prompts conflict, the memory gets polluted, the tools overlap. 6 months later the agent is doing weird things and nobody knows why lol.
17. Met a few people who carry two phones now. One for personal. One that's basically an agent terminal running Telegram or iMessage connections to their agent fleet.
It's always amazing to get that dose of inspiration in SF. I FEEL INSPIRED.
But I'm so happy to be back home, locked in and building.
We're 12-18 months into a shift that will take 15 years to play out. The urgency in every conversation was real.
What an incredible time to be building.
CLOUDFLARE CEO EXPLAINS HOW HE CHOSE WHICH EMPLOYEES TO LAY OFF DUE TO AI
This man just laid off 1,100 people during Cloudflare's best quarter in company history. $639.8 million in revenue. 34% growth. Record free cash flow.
He then wrote a Wall Street Journal op-ed explaining how he decided which employees to replace with AI.
His framework: every company has
1) builders (engineers)
2) sellers (salespeople)
3) measurers (middle managers, operations, HR, finance, analytics)
According to him: AI replaces the measurers.
He admitted he could not find a single example in U.S. business history of a public company growing at 30%+ that simultaneously cut 20%+ of its workforce. So he made himself the first.
The stock dropped 24% before rebounding steadily the past two weeks.
Nearly 1 million people applied for 1,111 Cloudflare internships. He cited that as a sign of opportunity. Read that ratio again. That is 900 rejections for every single acceptance.
So, I wonder: if AI truly made your employees more productive, wouldn't the rational move be to keep them and capture more output? You only cut if this is about margins. Not transformation. Margins.
Cloudflare has over a dozen roles open in India on LinkedIn, and has filed for 251 H-1B employees in the past 24 months.
A dog failed his service dog exam, and was later seen at a train station carrying the reason why.
People at the station couldn’t stop staring when the dog walked onto the train with a stuffed elephant held proudly in his mouth.
At first, everyone thought it was part of his training.
But his owner started laughing and explained the truth.
The dog had been training to become a service dog, but during one of his final tests, he kept getting distracted by an elephant plushie nearby. Instead of staying focused, he tried to steal it like it was the only thing in the room that mattered.
That was the moment he failed.
But his owner said he couldn’t be mad. The dog had tried his best, and even if he wasn’t meant to be a service dog, he was still loyal, gentle, and full of love.
So before they left, he bought him the elephant toy.
That night, the dog didn’t pass the exam, but he still went home with the person who chose him anyway.
My "36 biggest startup opportunities" tweet went viral.
I took the top 9 (AI, mobile apps, IRL) and did a full deep dive.

Happy building, I'm rooting for you
Underrated life advice: Make yourself easy to root for. Be kind. Be reliable. Celebrate other people’s wins. Work hard without complaining. Carry good energy into rooms. You'll be shocked by how many doors open for you by making life better for others.
I just had the craziest experience at the airport.
We are about to board a flight to Atlanta when the pilot from the incoming plane walks out of the jetway. Guy is probably late 50s, salt and pepper hair, military look. The kind of pilot you instantly feel good about seeing on your flight.
Pilot walks over to the counter, gets on the PA system, and starts addressing everyone. “Folks, I’ve been doing this a long time. Flying one of these jets is easy. The hard part is looking at 130 people and telling them their flight is going to be delayed.”
Audible groans throughout the boarding gate. Most people here are flying to Atlanta as a layover before another flight. 130 people just had their day become a complete mess.
The pilot goes on. “I get it, trust me. But here’s the deal: During our landing, we had a small mechanical issue. I’m not your pilot for the next leg, but I don’t feel confident the jet’s safe to fly until we have a mechanical team look it over, and I don’t feel comfortable asking the next pilots to fly you guys until we get confirmation.”
He points at the agents next to him behind the counter: “Now, none of this is the agents’ fault. Please be kind to them. I’m the one who made this decision, not them, so any inconvenience you experience is my fault. Just please know that I don’t do this lightly, and I’m only doing it because I believe it’s in the best interests of everyone’s safety.”
Now this is where the story gets crazy. The pilot puts the microphone down, grabs his suitcase, and all the people in the gate…
Start clapping.
I’m not joking, everyone starts clapping for the guy. 130 people who just had their travel plans ruined give an ovation to the guy who made the decision and delivered the message.
All because he addressed them with decency and transparency, took ownership of the decision, made it clear that it was necessary, and explained why it was in everyone’s best interest.
It’s honestly one of the best examples of strong communication—of strong leadership, for that matter—that I’ve seen in a long time.
@Delta, whoever your Atlanta to Wichita pilot was this morning, he’s one of the good ones. Please tell him the delayed passengers of flight 1637 appreciate what he did.
