About Us

Sweet Sour Sauce was founded by Mark, a consumer behaviour researcher who spent years watching small service businesses lose customers they should have kept. Not because of the quality of their work, but because of invisible psychological forces neither they nor their customers were aware of.

The research that explains those forces has existed for decades. Cialdini. Kahneman. Thaler. Ries and Trout. Peer reviewed, documented, and tested across thousands of real world business contexts. Most small business owners have never encountered it. Most of their competitors never will.

Sweet Sour Sauce exists to change that. Packaging decades of consumer behaviour research into practical, specific tools that independent service businesses can use immediately.

WHY CONSUMER PSYCHOLOGY

The principles we apply are not opinions or marketing trends. They are documented findings about how human beings make decisions. Findings that have been replicated across cultures, industries, and contexts for decades.

What makes them powerful for small service businesses is precisely how little they cost to apply. No ad spend. No technology. No team. Just a clear understanding of the moments that determine whether a customer trusts you, chooses you, or comes back. And what to do at exactly those moments.

A SIMPLE EXAMPLE

In the 1980s, researchers at Cornell University studied what happened when restaurants removed the dollar sign from their menus. Not the prices. Just the symbol.

Sales went up. Significantly.

The reason is documented consumer psychology. The dollar sign is a pain trigger. It activates the part of the brain associated with loss, making every price feel like something being taken away. Remove it, and the psychological friction disappears. Customers spend more without knowing why. This principle applies to any business that presents prices in a list or menu format. Spas, salons, clinics, trade quotes presented as itemised lists. The symbol costs nothing to remove. The impact on customer behaviour is immediate and measurable.

This is what consumer psychology looks like in practice. Small, counterintuitive, and backed by decades of research. There are hundreds more where that came from.
