Strike up applies to more than people talking. It also names how a partnership between organizations begins.
Yes: "strike up a partnership" or "strike up a collaboration" correctly describes a partnership beginning organically — through a conversation or a chance meeting — rather than through a heavily negotiated formal process. It applies to teams and organizations, not only to two individuals.
The sense advanced learners activate least
This sense is named directly in the word's own core definition alongside conversation and relationship, but it is the one advanced learners activate least — often defaulting to flatter phrasing like "we started working together" in exactly the retrospective and case-study writing where naming a partnership's organic origin matters.
"The design agency struck up a partnership with the analytics platform after their founders sat next to each other on a panel, months before either side's legal team was involved." The partnership is real and eventually formal, but its beginning was not.
"Our team struck up a collaboration with the platform group over a shared Slack channel, long before either manager knew it was happening." Same shape: an organic beginning that later became something structured.

The word covers only the beginning: it is a real overreach to use "struck up a partnership" to mean an agreement was signed or concluded at that moment. The organic conversation and the formal signing are two separate events, and only the first is what "strike up" names.
"We struck up a formal supply agreement after six months of legal review" is a partnership overreach — six months of legal review is not an organic beginning, so "negotiated" or "finalized" fits the sentence better than "struck up."
Practice scenarios
Practice using strike up in situations like:
- narrating how a business partnership first came together, for a case study or retrospective
- describing a cross-team collaboration that started informally before it was ever formalized
- correcting a sentence that treats a signed agreement as though it were the beginning
Useful practice phrases:
- "The two companies struck up a partnership after..."
- "We struck up a collaboration long before it was formalized."
- "We negotiated the agreement after we had already struck up the partnership."
Every partnership has an origin story and a paper trail, and they are rarely the same event.
Strike up is the word for the origin story, never the paper trail.
