Research at Letter Leverage | Writing Deep Dives for Social Capital

Jerusalem, Israel
Turpentine and @eriktorenberg are crushing the podcast content game. • 21 shows • 250K monthly views • Interviewed giants like @balajis, @austin_rief, and @gregisenberg Now they are expanding their business to newsletters. But they have a few leaks in their funnel costing them $$$. Problem - Social Traffic + Newsletter = Weak Opt-In - Current “Hook,” headlines, problems, and benefits could be stronger & more specific - Too many steps to subscribe - Welcoming email is weak - No intro video - Does not prime reader about next email - Does not tell reader how to remove email out of spam Solution Customized Educational Email Courses - Capture more emails, allowing you to attract more customers/clients/users - Establish trust with customers/clients/users on autopilot - Think of it as "The 5 biggest mistakes CFOs make in budgeting" vs. the vague "subscribe to our newsletter here" The goal here is to move your audience from social media ATTENTION to email-based RETENTION and CONVERSION. Erik, I sent you an email if you want to chat.
Turpentine is hiring a GM of Events, and a GM of Newsletters to help launch new business units for our growing media platform. Currently, Turpentine’s core product is a podcast network. We have launched 21 shows to date that bring in 250k unique monthly listeners, and until now @eriktorenberg has essentially played the role of "GM of Podcasts" — building the playbook of how we launch, produce, monetize, and grow our shows. We’re looking for someone to do the same for newsletters and events. Learn more through the below JDs: - GM of Events: docs.google.com/document/d/1… - GM of Newsletters: docs.google.com/document/d/1… And apply by sending us your LinkedIn or CV, and a few sentences why you'd be a good fit: erik@turpentine.co

On September 29th, Donald Trump hosted Mark Zuckerberg, Dario Amodei, Jensen Huang, and other tech leaders at the White House. The topic was the future of AI, and what it means for society. The message from the top was clear: AI will do more and more of our thinking for us. If I had a seat at that table, I would have told the President to encourage Americans to go back to the library. For the past year, I’ve used AI for almost all of my research. Recently, I was tasked with an undisclosed deep dive, and most of my research so far had been YouTube videos, AI, and Google. So I decided to try something different. What if I went to the library, where people have gone for thousands of years to expand their knowledge? I felt an inner calling to go to the National Library of Israel in Jerusalem. I had forgotten the beautiful feeling of getting lost in a library. Following my curiosity. Letting my eyes land on an interesting book on the topic I’m working on, and diving deeper. Sometimes I’ll spot a Dostoevsky novel, get lost in it, and somehow find a monetary connection that fits right into the deep dive. In an age when information comes easily and AI gives you exactly the answer you asked for, getting on a bus for twenty minutes and taking the time to find the book, then the page, is worth it. Today I spent about five hours here exploring one part of the deep dive, something I would have spent 30 minutes on online. And I came away with far more than 30 minutes ever gave me. Boy, was it awesome.

SpaceX's IPO created thousands of new millionaires in this small city of California. On June 12th, 2026, SpaceX went public at $135 per share, valuing the company at ~$1.8T at its IPO price. 7.6K SpaceX employees based in California, including executives, engineers, nontechnical staff, entry-level workers, and even cafeteria employees benefited from capital gains. At least 4K current and former SpaceX employees will become millionaires, with about 400 earning $100M+. Social Capital made a deep dive about SpaceX's IPO. While I was not part of that one, here are three insights I particularly enjoyed reading: 1. SpaceX Is worth nearly three times the entire space economy. The space economy, rockets, satellites, and ground stations combined, generated $626B in revenue in 2025. SpaceX is going public at a $1.8T valuation, roughly three times what the whole industry earns in a year. A multiple that size cannot be a bet on today's space economy. It is a bet on telecom, the $2.1T a year the world spends on phone and internet connections. Satellites deliver under $15B of that today, and the valuation prices in that share growing. 2. SpaceX collapsed the cost To orbit by 20X. Low Earth orbit, or LEO, is the region where most satellites operate, at an altitude between 160 and 2,000 km above Earth's surface. NASA's Space Shuttle was a reusable spacecraft that carried crews and cargo from 1981 to 2011. It cost $54,500 per kilogram to reach LEO. SpaceX has driven that price down to about $2,700, a 20x reduction documented in NASA's own cost analysis. Its flagship rocket, Starship, targets under $500 once fully operational, a 100x cut from the Shuttle. That makes SpaceX the chokepoint for everything that depends on reaching orbit. 3. Starlink, the global wifi provider, is the biggest revenue maker for SpaceX. They reported 10.3M subscribers at the end of Q1 2026, more than double a year earlier. At that scale, Starlink turned $11.4B of revenue into $4.4B of operating profit. P.S- LWM has one for Anthropic coming up soon if you are interested in reading more IPO deep dives!

Israel has more children per family than any other country with a GDP above $500 billion. Walk the streets of Jerusalem or Tel Aviv and you'll notice it right away: parks full of kids, parents pushing strollers on every block. And it's not just the ultra-Orthodox. Yes, Haredi families average around six children, but even secular Jewish Israelis average about two, still well above most developed countries. Now you might be asking: "Menajem, why is Israel different?" While researching this Deep Dive for Social Capital, I wondered the same thing. And reached out to Michael Eisenberg, managing partner at Aleph VC and a father of eight. He highlighted how cultural imagery influences desire formation: “The pictures you see on Middle School textbooks can help you determine how much a society desires larger families or not. If you see just a mom and a dad without children, this is what they are going to desire. However, where I live, there are like 4 or 5 children in the middle school textbooks when they describe a family. And it has nothing to do with religion but rather what is valued here. What a successful person is. And they want to mimic it, they want to be seen as successful in their community.” In this deep dive, we were curious about one question: is population collapse actually a crisis, or just a demographic adjustment? And investigated it in five layers: 1. Biology: The Limiting Factor 2. How Tech Changes Human Reproduction 3. How the Cost of Children Reshaped Fertility 4. How Culture Impacts Raising Families 5. Effective and Ineffective Institutional Policies You can find the link to the full deep dive in the X post if you are curious! x.com/chamath/article/203323…

Last week I met @FarroYossi over coffee in Jerusalem. I was impressed by his drive to make the Rebbeh of Lubavitch's mission of wrapping tefilin with jews, a reality. Tefilin are like an antenna to connect to the divine through prayer, and by facilitating that, he is helping a lot of people feel more spiritually aligned. He mentioned one time in LA, he wrapped Tefilin with a stranger and took a picture with him. Then someone pointed out that was Lil' Dicky. He had no idea. Then he crossed path with James Franco (the actor in the Interview), Scooter Braun, other celebrities in LA. Now he is more involved in the tech, VC, and startup world. Right after my meeting with him, he met Moshe Shalev at the King David, whose company, DecartAI was almost acquired by Anthropic for $6B. What was fascinating to me was how a group of teens approached us and asked Yossi to take a pic with him. Moshe and I stepped backed and smile (and in my head, I was like, can I take a picture with you Moshe?.... for next time). As an outsider, I told Yossi I used to be critical of his work. But after meeting him, I told him, my criticalness came from a place of insecurity inside myself and I found it is inspiring what he is building at 23. Keep on building Yossi, the compounding effect is just starting.

Exposing a @Priceline theft... On May 31st, Priceline failed to notify me of a cancelled flight from Tel Aviv to Madrid on Air Europa, in violation of the FAA Reauthorization Act (PL 118-63) and US DOT automatic refund rules. Air Europa canceled the flight abruplty without notice on May 17th, but until June 3rd, Priceline still showed it was confirmed. I then spent 3-4 hours on the phone with them until I reached a manager who promised free rebooking on a recorded call. Which he mentioned I was not allowed to receive the recorded call due to privacy terms (something a previous supervisor lied to mw about) Then Priceline broke this agreement in writing. I paid out of pocket for a new flight. I am writing this post to expose the outright theft, negligence, and deception and because I find no other source but to fight this injustice online. @USDOT @FTC this is documented.

I lived in NYC for 4 years as a young builder trying to figure things out in my early 20s. It’s devastating to hear a socialist won the elections in the most capitalist city in the world. While I dont know what the future holds, I’m still grateful for so many opportunities from the city that never sleeps. Here are 13 things I’m nostalgic about: 1. Driving from Washington Heights to Queens to pick up three Bitcoin miners from a total stranger I met on BitcoinForum. Paying him in Ether. Then selling the miners on eBay and Facebook Marketplace for a profit. 2. There was an app that gave you your first free beer at a new bar you have never been. If you brought a friend, they got one too. But it shut down really fast because people were taking advantage of it. (cool idea tho). 3. Getting matched on JSwipe, setting up a date at LeMarais… then realizing it would cost me $100 for food, drinks, and taxis, so I ghosted her because I felt financially insecure. (if i did this to you, i'm sorry.) 4. A Medium post I wrote about Ripple went viral and got me invited to speak at a blockchain event in midtown. (I was 20 back then.) 5. Organizing Shabbats in the Upper East Side at a billionaire’s home to complete his minyan. I only needed 10 but 40 people always showed up. 6. Becoming a wine pourer at a kosher wine festival in Chelsea Piers because I thought it would be a great lead gen strategy for my startup. 7. Getting “journalist” passes to events because I had a following on LinkedIn instead of paying $40 for the tickets. 8. Taking the “Shidduch Shuttle” from Midtown to Washington Heights at 2 AM after a nights out because I ran out of free Juno rides (Only YU people will understand this). 9. Skipping classes to attend networking events at the Microsoft office in Times Square. 10. Playing fútbol with a view of the World Trade Center feeling like Radamel Falcao. 11. My first taste of coworking spaces, visiting my brother’s office at WeWork Midtown. 12. Falling in love at a Shabbaton. Rejected. Falling in love again at another event. Dates. Let downs. And repeat and repeat. (What’s a single Latin heart supposed to do in NYC while getting a degree in marketing?) 13. “NYC, I Love You But You’re Bringing Me Down.” That song hit differently. 14. Getting freaked out by the subway madness, wondering why i lived there. 15. Organizing a hackathon for 200+ students. One of the winners was in the VR space. And when I was cleaning up, I unplugged the computers and the winner did not save his data. So it was all lost. (OFC I acted dumb like it was not me, like the Homer Simpson hiding to a bush meme). What’s one thing you feel nostalgic about in NYC?

MrBeast just uploaded this video he filmed 10 years ago He dreamed of having 1M subscribers by now on YouTube (he as 443M). This got me reflecting the dreams I had 10 years ago. One of them was to live in Israel which came true! What big dream you had 10 years ago that came true?

24 hours, Buy Me a Coffee suspended my campaign to send free coffee to IDF soldiers. All funds were blocked. And I now have to refund supporters. I felt frustrated. But something amazing happened. The community stepped up to get this project back on its feet: • 2 builders spun up a replacement from scratch so this problem wont happen again. (thank you Jorge Rybar and David Stiebel for vibe coding them) • The founder of ZenGo (@OurielOhayon)reached out to help set up crypto payments. • People suggested I reach out to @USAmbIsrael for help as well (anyone have direct contact?) • We will partner with a non-profit for this initative. I’m working to relaunch now and would love to raise 100 coffees in the next 24 hours (we hit 50 before the suspension). If you want to help, comment "COFFEE" and I’ll share the new link and ways to contribute (including crypto).

Dear @buymeacoffee... your team just DENIED my account. I'm a barista based in Jerusalem and I wanted to give free coffees to IDF soldiers dedicated by friends from abroad. You are not going to say it because your team is politically correct. But I am not a fool. You denied it because I serve 18-20 year olds in the IDF? We raised 50 FREE coffee cups from support of friends from all over the world. I provided enough evidence. But it seems you removed your anti-semitic mask yourself. Young adults in Israel need more joy in their distress work. They happen to wear an army uniform. I no longer seek to use your platform and I urge other creators to do the same. Any Israeli competitor working on something similar I can migrate to? CC- @HilzFuld

Someone in NYC bought 18 coffees for IDF soldiers in Israel. (I am confident someone in X can match it ;)) I recently launched an initiative at the Rova Cafe. Where anyone from anywhere in the world can buy a coffee for an Israeli soldier at the coffee shop I work. We get hundreds of these heroes order their favorite morning drink. So why not surprise them and let us the baristas say: "a friend from across the world wanted to dedicate this drink to you" Join this initative today! buymeacoffee.com/israelsoldi…

This Israeli Druze artist splashed paint all over my shirt. His name is Sam Halaby and he grew up in Daliat Al Carmel in Northern Israel. He found his passion for painting after his mom got sick when he was 9. She was given 2 months to live and as a way to cope with the pain, he splashed all sort of colors in his room. And noticed he really enjoyed doing this. His father and 9 sisters noticed as well. And they encouraged him to continue. And he did! During the good days and the hard days when his mom passed away and then his father some years later also. Eventually the sisters moved out and Sam kept painting literally the entire house. From the bathroom, rooftop, piano, and shoes. Red, blue, yellow, green, orange, and purple all over. All in a place he felt home when his biggest supporters were not here anymore. I felt inspired, but i was feeling something heavy for some reason when I was there. While walking around, I reflected a time I painted the wall of my house in Miami when I was 9. It was with permanent markers and I felt like an artist trying to draw a green and yellow garden. Then suddenly my dad walked in the backyard and saw me in flow creating my masterpiece. He was not pleased and I thought I was about to get grounded (sorry dad 🙃). But he smiled after and thanked me for trying to beautify the house during a difficult time for our family. Life will take you places so you can go back to a memory and reframe it. For years I had this personal story stored negatively in my backlog due to different reasons. But Hashem makes you relieve a similar situation in order to release the pain which needs an update with more accurate information. Once you have more accurate information you create a space. Which you can fill it up with more colors to beautify your inner self.
