rrapidly Worked example

From a bookshop brief to a customer test.

A suburban bookshop wanted more weekday visits and a younger regular base. Rapidly generated three ideas, helped choose one and turned it into a test the shop could run with real customers.

The short version

Rapidly takes an idea through the thinking needed to test it: the customer problem, what must be true, the behaviour that would count and the smallest experiment worth running.

This example keeps the full output so you can see how the recommendation was reached. The figures are proposed targets for a hypothetical bookshop, not customer results.

01

The idea

Rapidly generated three. We chose one to take forward.
The brief"A suburban independent bookshop wants to grow weekday foot traffic and build a younger, regular customer base."

Weekday "Third-Place Pass" Chosen

A low-cost monthly pass for weekday regulars: a guaranteed two-hour seat, one rotating perk and a members-only shelf of staff picks that refreshes weekly. The aim is to make quiet weekday visits a habit without turning the shop into a coworking space.

Also generated: a Libro.fm "Listen Local" audiobook-to-print rewards ladder, and stamped weekday "Reading Routes" with neighbouring cafés and schools.

02

The lean canvas

The business model for the chosen idea.
Problem

People want a pleasant weekday place to work or read for a couple of hours without paying coworking prices, but never build the routine.

Solution

A monthly pass: one guaranteed two-hour weekday seat, a rotating perk and a weekly members' shelf.

Value proposition

A low-cost weekday pass that turns a beloved local shop into a regular third place without the feel of a coworking space.

Key metrics

Active members and churn; weekday check-ins and seat occupancy; incremental profit per member.

Unfair advantage

Community goodwill, a welcoming space that's already a weekend third place, and staff curation that's hard to copy.

Channels

In-store offer, newsletter and Instagram, plus local partners such as cafés, campuses and parent groups.

Customer segments

Under-40 remote or hybrid workers; postgraduate students; parents with a post-drop-off window.

Early adopters

Weekday browsers who'd convert with a nudge; nearby remote workers craving structure.

Revenue streams

Monthly membership; incremental in-store spend; partner-funded perks.

Cost structure

Perk or discount cost; weekday overhead; programme administration and communications.

03

What needs to be true

The riskiest assumption is whether enough people will pay.

Customer hypothesis

Nearby under-40 regulars who like the shop but don't visit consistently will buy a monthly Third-Place Pass and use it at least twice a week if it gives them a reliable, low-commitment weekday place to work or read without coworking prices.

Proposed pass mark For testing

At least 15% of weekday regulars and nearby remote or hybrid workers who see the offer will buy the pass within 30 days. Among buyers, four or more weekday visits in the first month would show ongoing use.

Why 15%
Rapidly proposed 15% as a starting threshold based on similar local membership offers. The shop would review that target before running the test.

The experiments

Five practical options, all measuring payment against the proposed 15% pass mark.

  1. Start free: staff offer the pass to people already working or reading in the shop.
  2. Then test the page: use a counter QR code and landing page with people who already know the shop.
  3. Then test repeat use: run a 10-pass manual pilot and see if buyers return at least four times.

The test assets

Everything needed to put the offer in front of customers.

Landing page

A simple page explaining the $19 offer and refundable deposit.

  • The price and benefits are clear
  • The deposit creates a measurable customer action
  • Source tags separate in-store, Instagram and email visits
Open the landing page

Customer creative

Creative for people who already know the shop.

  • In-store QR card and staff script
  • Instagram stories and email or SMS copy
  • Guarantee-versus-perk copy to test later
What this example shows
Grounded starting point

Ideas based on the real brief

The options respond to the shop's actual goal. One draws on Libro.fm's existing bookshop partner programme.

Measurable behaviour

Payment instead of opinions

The test asks people to pay or leave a refundable deposit, then compares that behaviour with the proposed 15% pass mark.

Sensible order

Start with the cheapest test

Begin with a free staff offer, then test the landing page, then see whether buyers return.

Ready to run

The assets are already built

The shop gets a landing page, counter card, staff script, Instagram creative and customer messages.
