About Us - MarketOpen Australia

MarketOpen is an online media business connecting companies and investors. Led by Managing Director and MarketOpen podcast host Stewart Walters, the company was founded in Perth during the pandemic years by a small group of Western Australian investors with decades of experience in the Australian, British, Canadian and US markets, and the media industry. Through its flagship MarketOpen.com.au media channel and MarketOpen Magazine email newsletter, the publisher’s experienced journalists cover breaking news and analysis on mining, oil and gas, technology and biotechnology companies listed on the Australian Securities Exchange and other markets. MarketOpen’s video and podcasting channels feature original interviews with Australia’s small-cap corporate leaders, while its Stock Soirée networking events, Watchlist webinars, and online events connect investors and brokers with CEOs and board members. The publisher also offers a suite of agency services to its corporate members, including media, video, podcasting and social media services, along with writing, editing, reviewing and content creation services.
