Strike up and start can both describe the start of a conversation. They differ in range, tone, and common word pairings.
Start is neutral and broad. It works with a project, process, meeting, or conversation. It does not explain the manner of the beginning.
Strike up is narrower and more social. It is most often used with conversation. It can suggest an informal approach, but not a random or pleasant result.
Start means neutral beginning
"I started a conversation with the client about the renewal."
This is correct and clear. It does not say whether the exchange was planned, awkward, easy, or accidental.
Strike up has a social tone
"I struck up a conversation with the client over coffee before the meeting officially started."
This wording adds a social tone. Coffee gives the scene an informal setting. The phrase alone does not prove that the exchange was easy or unplanned.
The practical difference
Compare:
"I started a conversation with someone from product after the all-hands."
With:
"I struck up a conversation with someone from product after the all-hands."
Both are grammatical. The second is a familiar social expression. Someone still initiated the exchange, and it could have been intentional.
Start fits a much wider range of objects. Strike up strongly favors conversation. Dictionaries also record pairings such as an acquaintance or friendship. Those pairings may sound dated or less usual in some settings.

See how Lyra Practice works →Where strike up doesn't substitute for start
Because strike up has limited pairings, it cannot replace start for most procedural beginnings.
Incorrect:
"We struck up the onboarding process for the new client."
Correct:
"We started the onboarding process for the new client."
For a process or project, choose start, begin, or initiate. Check the object, not only the general idea of beginning.
Common mistakes
Mistake 1: Assuming strike up fits every formal report.
Too casual:
"We struck up a relationship with the enterprise buyer last quarter."
More formal:
"We began building a relationship with the enterprise buyer last quarter."
The first version is not wrong because it is formal writing. Still, it may sound too casual or suggest a quick social beginning. The revision describes a longer business process more clearly.
Mistake 2: Using start where strike up would add useful color.
Flat:
"I started talking to someone at the conference."
More natural:
"I struck up a conversation with someone at the conference."
Use strike up when the social opening matters. Do not use it to claim that the full conversation went well.
Where each fits
| Situation | Better expression |
|---|---|
| Any formal or procedural beginning | "Start" |
| A conversation with a social opening | "Strike up" |
| An executive report or formal document | "Start" / "Begin building" |
| An informal networking story | "Strike up" |
