21-Year-Old Mark Rachapoom: Co-Founder of YC-Backed Merse, Revolutionizing a $300B Industry

In the competitive $300 billion digital content creation market, Merse (YC S24) is emerging as a standout. Led by 21-year-old Mark Rachapoom, Merse has secured backing from Y Combinator, a startup accelerator with a track record of producing 125 companies valued at over $150 million each.

Rachapoom's journey from Rayong, Thailand to Silicon Valley is marked by exceptional achievements. His first app, Diary Dingo, reached the top 3 in Apple's App Store lifestyle category within 24 hours.

Merse's acceptance into Y Combinator's S24 batch by Garry Tan, President & CEO of Y Combinator, came with a $500,000 investment, placing it among the top 1.5% of applicants in a program that has launched over 4,000 companies now worth a combined $600 billion. This backing, from the accelerator that launched unicorns like Dropbox, Airbnb, DoorDash, Reddit, Coinbase, and Instacart, validates Rachapoom's vision of design-centric AI applications.

"Mark Rachapoom has a really high unfair advantage on design and providing exceptional experience for users," notes Aaron Epstein, Y Combinator partner.

Merse's potential has been further recognized by its acceptance into the Vercel AI Accelerator program, overseen by Guillermo Rauch, CEO of Vercel—a $3 billion company. This program selected only 40 participants from thousands of global applicants, placing Merse in an elite group of AI-driven startups.

The company has also secured investment from Daniel Doyon and Tristan Homsi, founders of Readwise—a platform with over 300,000 subscribers, aligning Merse with industry leaders in the $31 billion e-learning market.

As AI becomes more prevalent in creative tools, Merse is setting new standards in a field where giants like Adobe and Canva are also competing. Rachapoom envisions Merse disrupting industries dominated by companies like Webtoon, the $1.37B a year revenue megacorp.
