The cooler

One cooler that keeps food hot and drinks cold.

Foil insulation and a thermal wrap hold heat on one side. Hard-plastic insulation keeps drinks on ice on the other. A 1.5″ insulated divider keeps them apart, so game-day pizza and cold drinks ride in one box.

Built in 3D

The cooler you just spun is a model I made. I had never used 3D software, so I taught myself Adobe’s Substance 3D Collection from YouTube and Adobe’s own tutorials.

Self-taught

A business plan usually stops at a sketch. I wanted investors to see the product, so I learned the tools to show it.

Research

I wrote and analyzed our customer survey, pulled the secondary data and turned it into the demand forecast. Each big call in the plan traces back to a number.

Markets

We sized three possible markets, picked the one with the most to gain, then profiled exactly who buys and how many will.

Step 1

Three markets, one target

If every person in all three bought one cooler at $275, that’s $12.30B. Millennial parents are two-thirds of it. Pick a market to see the math.

Priority 1 · target market

$8.19B

74.19M millennials×55% parents×73% kids in activities×$275

74.19 million U.S. millennials, 55% of them parents, with 73% of children in extracurriculars.

They value convenience and family-first products that save time, and 74% discover products on social media.

Demand

How many will buy. A startup-sized 0.11% share of 29.78 million target parents, growing 8.2% a year. A premium cooler lasts about four years, so each buyer counts as a quarter of a cooler a year.

Role
