Operations
This is where the company's largest headcount sits (14 people). Operations leaders live in the concrete: a pilot scoped on one process will convince more than a demo.
Finance
The company's second-largest department (6 people). Timing matters here: approach them around budget planning cycles, when arbitrations are actually open.
Other
A team of 5 people. Hard to read from the outside: use a first exchange to map who does what before pushing an offer.
Sales
This department counts 5 people. Talk numbers (conversion, cycle length, pipeline coverage) and you will get their attention quickly.
Administrative
3 people work in this department. Repetitive tasks weigh heavily here: quantify the hours saved and you will hold their attention.
General Management
A team of 3 people. General management thinks in strategic priorities: link your value proposition to one of theirs or you will not get a reply.
