14/14 What's the biggest lesson here - that failure is just expensive education, or that sometimes you need to step away to gain perspective?

13/14 Marc's formula: Start with the smallest version possible. Ship fast. Build where you're comfortable sharing (Twitter, TikTok, wherever). Don't quit before you win. 🔚

12/14 This is key for anyone building: Product-market fit feels different. You stop convincing people to buy - they start asking how to pay you.

11/14 Expected $100. Made $500 in 2 hours while skating. First month: $40K. Peak: $135K/month. People were begging to give him money.

10/14 He launched 6 apps in 7 months. Still only making $1K/month. Then he built shipfa.st - a code template for other developers.

9/14 New rules: Never spend months on a product. Ship fast, test immediately. Build in public to create an audience for the next attempt. ⬇️

8/14 6 months later, he got fired. Instead of panic, he felt relief. He was ready to try again, but differently this time.

7/14 But here's the twist: The job gave him something entrepreneurship hadn't - a sense of worthiness. Creating value for someone who actually needed it.

6/14 At 28, married and broke, Marc did something he never thought he would: got a $9K/month engineering job. After years making $1K/month, it felt surreal.

5/14 Then COVID hit. Revenue went from $4K/month to zero overnight. Everything he'd built for 2 years - wiped out in 24 hours. ⬇️

4/14 His first sale: Cold emailed escape room businesses. One 42-minute call = first customer who said "send me the invoice." No fancy product, just validation first.

3/14 The turning point wasn't another "brilliant idea" - it was when he stopped trying to build the next Facebook and started solving real problems people would pay for immediately.

2/14 But here's what shocked me: He failed 30 startups over 5 years before his breakthrough. Living with cockroaches, zero savings, punching walls from frustration.

1/14 Today I learned about @marclou.bsky.social, who went from making $10/hour as a waiter to $1.5M/year as a solopreneur... 🧵⬇️

6/6 The real question: Does this systematic approach to "inspired" products represent the maturation of the startup ecosystem, or does it risk commoditizing innovation itself? #BuildInPublic #Entrepreneurship #SaaS

5/6 This connects to a broader shift in entrepreneurship - from "move fast and break things" to systematic execution of proven concepts. In an AI era that democratizes coding, competitive advantage comes from market research and execution speed rather than technical barriers.

4/6 His tech stack (Next.js, Node.js, Vercel) and operational costs ($4K-5K monthly) demonstrate that modern SaaS can achieve significant revenue with relatively lean infrastructure. The key insight: boring, simple tools often outperform complex innovations.

3/6 What's particularly insightful is his traffic source analysis. Apps growing through both ads AND SEO signal strong product-market fit. SEO-only growth requires patience but offers compound returns. Ad-only growth suggests you can replicate quickly but may indicate weaker organic demand.

2/6 His framework is methodical: find apps with proven traction (MRR screenshots on Twitter), analyze traffic sources via Ahrefs, ensure technical feasibility, and verify personal interest. This isn't copying—it's strategic market entry based on validated demand.

1/6 Samuel Rondot's $35K/month app empire challenges the innovation mythology that dominates startup discourse. His systematic approach to "cloning" successful products reveals something profound about market validation and execution risk.

12/12 If he could have any superpower, it would be distribution. Building an audience is key to launching new ventures. What's your biggest takeaway from Charlie's journey? Let me know! #BuildInPublic #Entrepreneurship #SideHustle (12/12) 🔚

11/12 Today, Liinks runs itself, allowing Charlie to explore new projects, including generative AI. He's a solo founder, with his 'AI robots' handling 50% of his coding. (11/12) ⬇️

10/12 He's launched over 20 projects, not all for profit, but each a learning experience. This iterative approach is how you find what sticks. (10/12) ⬇️

9/12 Charlie's advice for aspiring entrepreneurs: Don't quit your job until your side hustle is truly holding you back. Use your current job to build and validate your ideas without risking your savings. (9/12) ⬇️

8/12 He also launched a 'pro' tier for users managing multiple profiles, an idea that came directly from customer requests. This unexpected revenue stream now accounts for a quarter of his income! (8/12) ⬇️

7/12 From $1K to $10K MRR, things slowed. More competitors emerged, and Charlie had less time. He pivoted to maintenance mode, relying on Google search ads for scalable growth. (7/12) ⬇️

6/12 He launched on Product Hunt and offered a free, more powerful alternative to Linktree's free plan. Within 6 months of shipping the MVP, he hit $1K MRR. That's fast! (6/12) ⬇️

5/12 liinks.co is a link-in-bio tool, similar to Linktree. But Charlie built it with more power and customization. He even onboarded early users manually, asking for feedback and building features they requested. (5/12) ⬇️

4/12 His secret? He followed his own curiosity, solved his own problems, and launched into a market with clear demand but low competition. This is key for anyone looking to start. (4/12) ⬇️

3/12 He used that time to build the foundation for what would become Liinks. He worked nights and weekends for almost 4 years, growing it to $25K MRR before quitting his job for the second, and final, time. (3/12) ⬇️
