Two opposite mistakes come from misjudging where strike up fits, and they pull in exactly opposite directions.
"Strike up" is comfortable in narrative, conversational business writing — case studies, LinkedIn posts, retrospectives, internal updates, cover letters, bios, interview anecdotes — and a weaker fit for strictly formal, legal, or transactional documents like board minutes, contracts, or regulatory filings.
Too stiff, or too casual
Rewriting a genuinely easy, organic beginning into stiff, formal language ("initiated a professional dialogue with") loses the natural, human texture strike up is built to carry — a real register loss in the writing meant to sound human, not just a synonym swap.
Using strike up inside a board minute, a contract, or a regulatory filing reads as too casual for the channel, even when the underlying event genuinely was an easy, unplanned beginning — "established", "began", or "formed" fit that register better.
The event doesn't change; the channel does
The same content can shift register across channels without losing accuracy: a casual Slack recap of how a client relationship began can be adapted for a LinkedIn post or newsletter by adjusting tone and framing, while the underlying strike-up event stays the same.

Start learning for free →"I struck up a great conversation with the panelist after her talk" — natural in a LinkedIn recap or a cover-letter anecdote.
"The Board notes that the Company initiated a professional dialogue with the counterparty on [date]" — correct for the formal register a board minute needs, even if the actual event was an easy, unplanned hallway conversation.
"Per Section 4.2, the parties struck up their business relationship in March" is too casual for a contract; "the parties established their business relationship in March" fits the channel.
Practice scenarios
Practice using strike up in situations like:
- writing a LinkedIn post or case study about how a relationship or partnership began
- drafting a board minute or contract clause about the same underlying event
- adapting a casual Slack recap into a more formal newsletter or announcement
Useful practice phrases:
- "I struck up a great conversation with... (casual, narrative writing)"
- "The Company initiated a professional dialogue with... (formal writing)"
- "The parties established their business relationship in... (legal or contractual writing)"
The right register depends on the channel, not on whether the underlying beginning was actually informal.
A genuinely organic beginning can still need formal phrasing once it's being recorded in a legal or transactional document.
