Opsize

In the high-stakes world of startups, expertise matters. OPSIZE works with Aussie startup founders, providing hands-on coaching and advisory services to help them navigate the complexities of building and scaling a business. We are not a consulting firm pushing frameworks and recycled business theory. Founded by serial entrepreneur Kev Jochelson, our team consists of seasoned founders and early-stage operators who have built, scaled, and exited businesses themselves. We bring that firsthand experience to every founder we work with—cutting through the noise, stress-testing ideas, and guiding startups to product-market fit and their first taste of revenue. With real-world experience and a fast-paced, execution-driven approach, OPSIZE helps founders make smarter decisions, avoid costly mistakes, and accelerate their path to success. No empty promises—just the strategies, insights, and support to take your business to the next level. Want in? The best way to reach out is to Kev directly on Instagram:
