Who stocked this shelf
A snack has to taste good enough to buy again. It also has to be practical to make, priced for its market and ready for retail.
My career began in finance, audit and business development. Today I bring that commercial discipline to food: balancing ingredients, texture, nutrition and production cost, then learning from consumer feedback and shelf performance.

1,000+ product trials. The work is in the details: ingredients, nutrition, texture and what people come back for.
Work with KDCompare taste, source, cost and stability before an ingredient earns its place in the formula.
Set the protein, sugar and calorie targets. Reformulate until the taste and texture work with them.
Test the crunch, chew and melt. A nutrition label cannot fix a bite people don’t enjoy.
Compare flavours, formats and price points against what shoppers already choose in each market.
Let people taste it. Use their feedback to decide what stays, what changes and what needs another trial.
Follow sales, repeat purchase and margin after launch. Use the shelf data to improve the next batch.
Work with me
Bring a product idea, a formulation problem or a plan for a new market. I work with founders, food brands and distribution partners.
