The day before giving birth, Sally Obermeder was diagnosed with cancer. During chemotherapy, she promised her sister they would build something together if she survived. Years later, the business they built was three months from bankruptcy. To save it, Sally had to look beyond growing sales and understand what the numbers were really telling her.

Key takeaways

• Revenue growth can mask a business walking toward bankruptcy if you don't know precisely where the profit is coming from.

• Blended revenue streams without SKU-level visibility let profitable products quietly subsidise unprofitable ones.

• Cost erosion is rarely one big number, it's death by a thousand small, easy-to-ignore cuts.

• Financial literacy has to be built in from day one, by the time you notice it's missing, it's usually expensive to fix.

The day before giving birth to her first child, Sally Obermeder was diagnosed with Stage 3 breast cancer. During chemotherapy, unsure what the future held, she called her sister Maha Corbett. If she made it through, she said, they would build something together that helped people feel good. They had no product in mind. They had a promise.

As Sally recovered, green smoothies became part of her daily routine, before kale was a household name and  when people were still horrified she was blending spinach and drinking it. She felt the difference first-hand as she tried to rebuild a body chemo had wrecked. That became SUPERGREENS, the brand's first product and the beginning of what is now ZIISH.

“I didn't know what it was, I didn't have a product idea, I just had that promise."

What followed is a decade of being first rather than following, green smoothies, green powders, early into collagen well before it became crowded and Australia's first NAD-boosting supplement. Alongside that, a community-first, founder-led approach to education that predates "founder content" as a category. Sally is proudest not of a single milestone but of the people who stop her in the street to say a ZIISH product has been part of their life for years, alongside launching nationally into  Priceline stores nationally  and into Boots in the UK, on the strength of a bootstrapped, personal-story brand.

The lesson that changed how the business was run
Early on, the business didn't have a proper pricing model or real visibility over margins. Revenue streams blended into one melting pot, so it wasn't clear what was actually working. Profitable parts of the business were quietly subsidising unprofitable ones, until it all came to a head and Sally and Maha discovered they were three months from bankruptcy. To protect their staff's jobs, they cut their own salaries to zero and stayed there until they'd found a real path forward.

“We found out we were basically three months from bankruptcy."

The most profitable decision she ever made
Cutting unnecessary expenses, not as a single big number, but by going SKU by SKU and being honest about what was actually working. Some of the hardest cuts were to products she'd built with her own hands and genuinely believed in. Profitability isn't a year-end check for Sally; it's the lens the business runs through constantly, on every channel and every line item.

What she'd do differently, starting today
Go in with a clear business plan from day one, especially around margins. Get properly fluent in reading a P&L rather than glancing at a top-line number and assuming growth means health. Manage cash runway deliberately instead of reacting to it once it becomes a crisis. And look at performance SKU by SKU from the very start, instead of judging the business as one overall picture, the exact blind spot that caught her out the first time.

"Revenue and activity are not the same as a healthy business."

Sally is candid about how little she understood at the beginning, that revenue, margins, cash flow and profit are entirely different conversations and for years she was only ever having one of them. She knew her customer intimately from day one. It took a crisis to know the business the same way.

F5 Collective exists for founders navigating exactly this, where the brand and the community are thriving, and the hardest work is still learning to read what the numbers are actually telling you.
