What Costco contributes

Costco is a membership warehouse club, and Uber Eats shoppers must verify a Costco membership before buying 5.

Members can buy a Costco membership through the Uber Eats app itself 5.

What Uber contributes

Uber's paid membership has more than 50 million 6 members worldwide 6.

Uber's paid members get no delivery fee on eligible Costco grocery and retail orders over a set amount 7.

The new company

Name idea

Working name: Bulkhaul. An independent membership delivery company, not a Costco or Uber product.

Product

A members-only bulk delivery service where a single membership covers both the warehouse prices and the delivery fee, which the Costco and Uber Eats tie-up combines across their memberships 1.

Customer

Households that buy in bulk and pay for delivery.

How it makes money

Membership fees plus a share of each delivered order, with the delivery perk tied to the membership as Uber's paid membership does 7.

Breed your own company

Each parent passes down four traits. The child takes every trait from one parent or the other, and sometimes one trait mutates into a random idea. The same link always shows the same child.

Traits Costco can pass down

Customer: Shoppers who hold a paid membership to buy goods at the warehouse club 5.
Product: A warehouse club membership that a shopper must verify before an order can be delivered 5.
How it makes money: Earns money by selling paid memberships that shoppers must hold before buying anything, including delivered orders 5.
Why it is hard to copy: Hard to copy because it already runs delivery through several outside delivery platforms at the same time 3.

Traits Uber can pass down

Customer: People who pay for a membership that unlocks delivery and ride perks across many partner businesses 6.
Product: A paid membership that unlocks delivery and ride perks across a wide network of partner businesses 6.
How it makes money: Earns money by selling a membership that removes the extra delivery charge on qualifying orders 7.
Why it is hard to copy: Hard to copy because its paid membership already reaches a very large base of members across many services 6.

Demand check

Google autocomplete for "costco x uber" returned 10 8 suggestions, so people type this pairing. Costco members can buy a membership inside the Uber Eats app and get a discount on an eligible order 7, so both companies are paying to reach the same shoppers.

Build plan

Start with bulk-order delivery for members in a single metro area 1.
Add a membership that bundles the warehouse price and the delivery fee 7.
Add scheduled orders for repeat household staples 1.

Copy the build prompt

Build a site for an independent membership delivery company for bulk goods. Show the membership, the delivery area and a signup form. State that it is independent of any retailer or delivery brand.

Risks and unknowns

Costco and Uber already cover 47 1 states and nearly 600 1 locations with a live tie-up, so a copy competes with both.
Costco's same-day delivery runs through Instacart, so the retailer already has another delivery partner 3.
