Sam Parr sat down for dinner with Mark, who co-founded both the expert-network giant GLG and a very different kind of venture: United Hatzalah. The origin story is stark. A child was choking. An ambulance was called. The ambulance didn't arrive in time. The child died — even though a doctor lived nearby and had no idea anything was happening. That frustration drove a man named Eli to start a small network of trained volunteers who could be dispatched faster than any ambulance. He started with 6 to 12 people, trained in CPR, the Heimlich maneuver, and emergency delivery, each carrying a 40-pound supply backpack. Mark gave him $18,000 and became his co-founder. [1] — Sam Parr "United Hatzalah is a volunteer emergency network in Israel with 18,000 volunteers who handle 2,000 calls per day. Their goal is a 90-second…" 09:03 Eighteen years later, United Hatzalah has 18,000 volunteers across Israel, handles 2,000 calls a day — one every 45 seconds — and operates with an average response time of 2–3 minutes against a 12-minute ambulance benchmark. Their goal is 90 seconds. They use AI trained on 18 years of data (heart attacks peak in the morning; people are home, not at the office) to pre-position volunteers. The network is powered entirely by donations and spends tens of millions of dollars per year. It's also, Mark told Sam, one of the only places in Israel where ultra-Orthodox Jews, secular Jews, Arabs, Muslims, and Christians work side by side — not through dialogue, but through shared action.
Shaan Puri attempted to use the rule of reciprocity by bringing Diet Cokes to a tense meeting with a school principal, but the principal refused the drink and shut down his program anyway.
United Hatzalah is a volunteer emergency network in Israel with 18,000 volunteers who handle 2,000 calls per day. Their goal is a 90-second response time, and they currently hit about 2–3 minutes — versus the standard 12-minute ambulance. It was built because a child choked and died while a nearby doctor had no idea.
United Hatzalah's mission is to reach any emergency in Israel within 90 seconds; they currently achieve an average response time of about 2–3 minutes, versus the standard 10–12 minutes for ambulances.
United Hatzalah, Israel's volunteer emergency network, handles approximately 2,000 calls a day with around 9,000 volunteers across the country.
Sam built Algrow from zero to $14,000 in monthly revenue within just six months of shipping his first MVP.
Algrow reached over 10,000 users in roughly six months, driven almost entirely by organic Discord community growth.
Sam acquired his first 400 users entirely through Discord communities, without paid advertising or traditional outreach.
Algrow added exactly 480 new paying customers in its most recent month, demonstrating strong ongoing growth.
Sam's Stripe dashboard showed over £10,000 in revenue in the last four weeks, equivalent to roughly $13,000–$14,000 USD.
Sam gave all early users free access so they could show the tool to friends, turning them into live demos and advocates who helped the product spread virally.
By silently screen-sharing his tool in Discord voice chats rather than posting links, Sam attracted curiosity without violating no-self-promo server rules.
Before building Algrow, Sam and two friends made over $10,000 in revenue through affiliate marketing for RizzApp by posting faceless texting story content.
