JJ Chai's entrepreneurial path is shaped by his diverse experiences across consulting, tech startups, and venture building. Beginning his career in a Singapore-based tech startup, JJ transitioned to McKinsey, where he worked across technology, telecommunications, and government projects. His time at McKinsey provided a deep understanding of corporate dysfunction and how startups could capitalize on inefficiencies.

Post-MBA, JJ joined Airbnb as its first Southeast Asia employee, leading the company's regional expansion at a time when it was still an underdog in the region. He played a crucial role in onboarding hosts, optimizing supply acquisition strategies, and adapting Airbnb's model to the fragmented and opaque Southeast Asian market. Later, he joined Carousell pre-revenue, helping scale the classifieds marketplace across multiple countries and business verticals. His experience at Carousell reinforced the importance of sustainable growth and the pitfalls of being overly reliant on venture capital.

JJ's inspiration for Rainforest stemmed from observing inefficiencies in marketplace models. He saw that many e-commerce sellers had great products but lacked the operational expertise to scale effectively. Coupled with his desire to build a profitable, self-sustaining business (rather than constantly fundraising like at Carousell), Rainforest was born. The company acquires and scales successful e-commerce brands, focusing on product, channel, and geographic expansion. While initially considering Southeast Asia-based brands, JJ and his team pivoted to acquiring Amazon-native brands, given the maturity of the ecosystem.

A key to Rainforest's success has been its deliberate approach to M&A. Unlike other aggregators that rapidly acquired brands, Rainforest remained disciplined, conducting thorough due diligence and avoiding debt-fueled acquisitions. This cautious approach proved prescient, as many competitors—like the once-hyped Thrasio—struggled under unsustainable business models. By focusing on high-quality brands and avoiding the post-COVID demand slump, Rainforest has maintained financial resilience.

JJ also discusses Rainforest's approach to integrating and growing acquired brands. While operational optimizations like better packaging and logistics are relatively straightforward, replicating a founder's product intuition and ability to create new bestsellers is more challenging. To address this, Rainforest fosters a culture of smart risk-taking, encouraging brand managers to experiment with new products and marketing strategies.

Company culture is another pillar of Rainforest's success. Built as a remote-first company, JJ emphasizes outcome-driven work, clear OKRs, and radical transparency in company finances and performance. Employees receive ESOPs, ensuring alignment with the company's long-term vision. Hiring at Rainforest prioritizes functional expertise for operational roles, while leadership positions demand entrepreneurial thinking and adaptability.

Beyond Rainforest, JJ is an active angel investor, focusing on founders who demonstrate resilience, adaptability, and a deep obsession with their problem space. He values entrepreneurs who can take feedback, iterate quickly, and persist beyond short-term setbacks. His advice for early-stage founders: stay lean, avoid chasing hype, and focus on solving real pain points rather than just raising capital.

As Rainforest evolves, JJ envisions it becoming a category-defining player in mother and baby products, leveraging data-driven product innovation and supply chain expertise. This episode offers invaluable insights into e-commerce, startup scaling, and the mindset required to build enduring businesses in a volatile economic environment.
