Y Combinator chief executive Garry Tan published a guide in April 2026 urging startup founders to be accurate about their revenue, drawing a line between non-binding letters of intent and recurring revenue that has actually been invoiced and paid.
The guide, posted on X under the title “Being Truthful And Precise About Revenue”, was aimed at a US startup culture where inflated numbers have become common enough for the world’s best-known accelerator to address them publicly. In Australia and New Zealand, founders and investors often describe the opposite habit: a cultural reluctance to promote success, commonly called tall poppy syndrome.
The US problem
Tan’s guide set out the difference between a customer signalling it might pay if a product works and revenue that is contracted, billed and collected, Artificial Lawyer reported. The fact that YC’s chief executive felt the need to spell out that distinction points to how far some founders had stretched their reported numbers.
The ANZ pattern
Some of the region’s most valuable companies remain little known at home. Airwallex, founded in Melbourne in 2015, provides cross-border payments infrastructure for global internet companies. Capital Brief reported its Series H lifted its valuation to US$11 billion in 2026, with annualised revenue of US$1.3 billion as of March.
SafetyCulture, which started in Townsville, now supplies workplace inspection software to businesses around the world. Both companies built global businesses while keeping a comparatively low public profile in their home market.
Precision without silence
The two extremes carry different costs. Overstating revenue can mislead investors and damage trust when the numbers are tested. Understating achievements can make it harder for ANZ companies to recruit talent, attract customers and win attention from global investors who are not already looking at the region.
The middle ground is precise reporting delivered with confidence: real numbers, clearly explained, without waiting for a company to become impossible to ignore.
Jack’s take
I think tall poppy syndrome is a genuine competitive disadvantage in 2026. If ANZ founders keep waiting until they are undeniable before speaking up, the world will have already moved on. Precise is not the same as quiet, and the YC guide is a good template for being both honest and loud.
