Before adding a fashionable technology or adjacent business, force the idea through four tests. First, explain how it fits the existing product hypothesis and thesis rather than merely matching an investor meme. Second, identify real customer demand or willingness to pay. Third, expose the operating difference: a consumer product, marketplace, SDK, and B2B infrastructure company require different skills, fulfillment, and support. Fourth, calculate the focus cost for the current team, especially when only a handful of people are available. If the opportunity still deserves an experiment, define success and exit criteria in advance and run a bounded test. The gate protects a working product from being forked across incompatible businesses while still allowing intentional experiments that can be stopped cleanly when the evidence fails.
Origin
Ramamurthy derived the warning from a failed peer-to-peer electronics expansion at her startup, Netflix's bounded 3D experiment, and a founder attempting consumer payments and an SDK with four people.
Core principles
- 01Investor excitement is not evidence of fit with the product thesis.
- 02Existing customer demand and willingness to pay outrank fashionable market narratives.
- 03A small team cannot pursue adjacent businesses without paying a focus cost.
- 04Experiments need explicit exit criteria before enthusiasm makes them difficult to stop.
How to run it
- 1
Test thesis fit
Write how the fashionable opportunity advances the product hypothesis and business thesis already being pursued. Reject explanations based only on market heat or investor language.
Pro tip Complete the sentence: this strengthens our current product because.
Watch out Adopting a trend to appear current is not strategic fit.
- 2
Test customer pull
Look for customers requesting the outcome, adopting a manual version, or showing willingness to pay. Distinguish curiosity from demand.
Pro tip Ask what evidence exists without mentioning the fashionable technology by name.
Watch out A large theoretical market does not prove that current customers need the adjacency.
- 3
Audit capability distance
List the new technology, logistics, fulfillment, sales, and support the idea requires. Treat a different operating model as a different business even when the customers overlap.
Pro tip Compare the required capabilities with the team's actual composition.
Watch out A feature can conceal a company-sized operational commitment.
- 4
Price the distraction
Name the roadmap, customers, and learning the current business will lose while the team pursues the adjacency. Make the trade-off explicit for the available headcount.
Pro tip Express the cost in team-months and delayed commitments.
Watch out Claims that every initiative will accrue value ignore the cost of divided attention.
- 5
Precommit the exit
Define the evidence and date that will cause the team to stop. Run the smallest experiment capable of reaching that decision.
Pro tip Write the shutdown condition before the first build sprint.
Watch out Without exit criteria, sunk cost and trend enthusiasm extend a failed experiment.
In the wild
Ramamurthy's startup had a working consumer-electronics recommendation business with retail partners. During enthusiasm for shared ownership, the team added a peer-to-peer product for people to list their own items. The adjacency required different logistics, fulfillment technology, and skills, splitting a small team away from the business already working. They eventually shut it down but, in her view, should have done so sooner.
→ The failed expansion revealed that a fashionable adjacency can be an operationally separate company rather than an additive feature.
When television manufacturers promoted 3D, Netflix experimented with the technology across roughly seven movie titles. The player work was difficult and the living-room experience with special glasses remained poor. Ramamurthy said the team entered knowing it was an experiment and had clear exit criteria, then pulled the plug.
→ A bounded test let Netflix explore an industry trend without mistaking it for a permanent strategic commitment.
Common mistakes
Following the investor meme
A trend can improve a pitch while pulling the product away from its customers and original hypothesis.
Calling another business a feature
New logistics, fulfillment, customers, or sales motions can make the adjacency a separate company in disguise.
Experimenting without an exit
A test without predefined stopping evidence tends to persist for months after its strategic case has weakened.
Is it for you?
Best for
Startup founders considering a hot technology, a second business model, or an expansion that promises a much larger market.
Not ideal for
Necessary pivots where the current thesis has already failed and the company must deliberately search for a different business.
