Welcome to Point Zero One – Hosted by Allen Fu. This podcast is about real stories, real strategies, and real results. No fluff—just insights from the best in the game.

In this episode of Point Zero One, we sit down with 24-year-old founder Sarah Woodger, the creator of Coastal Girl — the Australian haircare brand that went from launch to 100,000-unit production runs in under a year.

Before building her own brand, Sarah was a hairdresser from the Central Coast who moved to France to work on superyachts as a personal hairdresser for a billionaire family. It was there she kept seeing the same problem: dry, brittle, colour-faded hair after swimming in saltwater and chlorine.

Instead of accepting it, she built a solution.

Coastal Girl’s hero product — a cream designed to act like an “invisible swim cap” — took two years of R&D, multiple cosmetic chemists, and nearly $100,000 in development before it ever launched. Since launching in March, the brand has scaled rapidly, selling out its initial 10,000-unit run, expanding into wholesale across salons and surf shops, and now producing 100,000 units at a time.

We break down what actually drove the growth: product-market fit, founder-led content, Meta ads with Sarah as the face of the brand, salon trust, and disciplined reinvestment — without relying on influencers or UGC.

This conversation also dives into the realities of scaling: stockouts, cash flow pressure, manufacturing in Australia, funding production with Amex debt, 16-hour days, and building a business with her partner Luke while protecting the relationship.

💡 What You’ll Learn in This Episode: ✅ How to validate real product-market fit ✅ Why founder-led content can outperform influencers ✅ The behind-the-scenes of scaling physical products ✅ Managing stockouts, forecasting & cash flow ✅ Manufacturing challenges in Australia ✅ The mindset required to build at speed ✅ Sarah’s “cheat code” for long-term success

This is a practical, honest breakdown of what it takes to build something real — and scale it fast.

🔔 Watch now to learn how Sarah turned a recurring problem into a fast-growing brand — and what you can apply to your own 0.01.
