The architecture begins by selecting the person best able to lead the positioning decision rather than assigning ownership automatically by department. A small group—approximately five people—then focuses on the highest-leverage language: the short description that could appear between commas in a news article or on the company's main banner. The group debates whether this phrase clearly identifies the company, category, and useful distinction to an outsider. It does not begin with dozens of reviewers commenting on a long messaging document. Once the compact description is agreed, product marketing, PR, social, brand, and internal communications can build their supporting language from the same anchor. The output is a memorable core message that reduces contradiction while making every subsequent content and channel decision easier.
Origin
Katie Burke described the comma-length test and small-room process while discussing who should lead company messaging.

How to run it
- 1
Select the best owner
Choose the person with the strongest positioning judgment and ability to integrate company, customer, and market context.
Pro tip Let competence determine leadership rather than organizational territory.
Watch out Do not create co-ownership so broad that no one can decide.
- 2
Form a small working group
Bring roughly five essential perspectives into the room and keep the wider organization out of initial drafting.
Pro tip Include people who understand customers, product, brand, and the market.
Watch out A large reviewer list invites pet issues and compromise language.
- 3
Draft the comma phrase
Write the compact descriptor that could follow the company name between commas in a publication.
Pro tip Prefer words an informed outsider already understands.
Watch out Avoid jargon that requires another sentence to decode.
- 4
Test the banner
Ask whether the same core idea could guide the company's most prominent headline and help it win.
Pro tip Test the phrase with people outside the drafting room.
Watch out Do not polish supporting details while the central category remains unresolved.
- 5
Propagate consistently
Use the agreed phrase as the anchor for product positioning, PR, social media, internal communications, and longer message documents.
Pro tip Allow channel-specific elaboration without changing the central meaning.
Watch out Independent channel teams must not invent conflicting company descriptions.
In the wild
HubSpot needed people to understand that it sold software rather than operating only as a blog or agency. The compact description “an inbound marketing software company” could fit naturally between commas in press coverage and gave other messaging a clear anchor.
→ Prospects, journalists, and investors received a consistent explanation of HubSpot's category.
Common mistakes
Eighty-five document commenters
A huge review group becomes absorbed in wording details and loses sight of the central market position.
Starting with supporting copy
Detailed messages cannot align until the company agrees on its core category and description.
Letting departments diverge
Different descriptions across PR, social, product, and brand weaken recognition and trust.
Is it for you?
Best for
It is best for startups or repositioning teams that need one memorable explanation of what the company is and does.
Not ideal for
It is not ideal for detailed product documentation, where precision requires more than a short positioning phrase.
From the transcript
“message architecture and discipline sounds so boring, but it's a step that so many startups skip, and I think it's a huge mistake.”
“If you are in a messaging document and there are 85 people commenting in this messaging doc about whether it's uh just delete that freaking…”
“That description that fits between commas in print, that's what you should be fighting about, and then everything else dovetails from there.”
