What each function covers
Every job function in the taxonomy, what it includes, and the kind of titles classified into it.
IT 38,881,496
Everyone who builds, runs or secures the technology estate: software engineering, infrastructure and networking, data platforms, cloud, cybersecurity, and the service desk that keeps everyone else working. This is the single largest function in the file, and the usual buying center for software, infrastructure and security vendors.
Titles: Help Desk, IT Manager, Data Engineer, Founder & CTO, IT Consultant, SQL Developer, Web Developer, Data Scientist…
Operations 23,415,163
The people who make the physical and procedural side of a business work — supply chain, logistics, procurement, manufacturing, production, quality, distribution and facilities. Titles run from the plant floor to the COO, which makes this function unusually broad in seniority.
Titles: Supply Chain, Plant Operator, Inventory Clerk, Director and COO, Purchasing Agent, Procurement Clerk, Production Worker, Quality Assurance…
Sales 22,109,898
Revenue-generating roles: field and inside sales, account management, business development, channel and partner sales, and the sales engineers who support them. Typically the fastest-moving function in a contact file, because turnover and territory changes are constant.
Titles: Direct Sales, Sales Analyst, Sales Manager, Outbound Sales, Sales Director, Sales Engineer, Sales Consultant, Parts Salesperson…
Education 20,045,846
Teaching and academic administration — classroom teachers by subject, university faculty, instructors, librarians, admissions and registrar staff, and school leadership from principal to provost. Concentrated in education institutions rather than spread across industries.
Titles: Law Teacher, Math Teacher, Music Teacher, Health Teacher, Vice Principal, History Teacher, Physics Teacher, Academic Advisor…
Health 16,425,892
Clinical and allied health roles: nursing, physicians and specialists, dental, pharmacy, therapy and diagnostics, alongside the medical administrative roles inside care settings. Heavily regulated buyers, and a function where personal rather than corporate email is often the only route.
Titles: Pharmacy Aide, Medical Records, Dental Assistant, Dental Hygienist, Psychiatric Aide, Speech Therapist, Massage Therapist, Medical Assistant…
Finance 15,473,336
Accounting and financial management — controllers, accountants, tax, audit, treasury, payroll, budgeting, billing and collections, up to the CFO. Present in essentially every company, which makes it a reliable function to target across industries.
Titles: Tax Examiner, Tax Preparer, Budget Analyst, Tax Accountant, Tax Consultant, Finance Manager, Financial Clerk, Lead Accountant…
Trades 11,757,910
Skilled manual and field roles: electricians, plumbers, HVAC technicians, welders, machinists, carpenters, drivers, installers and field technicians. Mobile by definition, so a mobile number is often far more useful here than a desk phone.
Titles: Bus Driver, Taxi Driver, Cement Mason, Truck Driver, A/V technician, Lab Technician, Line Installer, Delivery Driver…
Marketing 10,632,559
Demand generation and brand — campaign management, digital and search, product and brand marketing, advertising, merchandising and marketing operations, up to the CMO. The function most likely to be buying data itself.
Titles: Brand Manager, SEO Specialist, Marketing Manager, Marketing Director, Advertising Manager, Marketing Specialist, Marketing Strategist, Marketing Coordinator…
Design 7,652,942
Visual and experience design: graphic, product, web, UX/UI, game, fashion and industrial design, plus art direction and creative leadership. Often sits inside marketing or product rather than as a standalone department.

Titles: Human Resources, Benefits Manager, Talent Management, Benefits Coordinator, Compensation Manager, Human Resources Manager, Human Resources Assistant, Employee Relations Manager…
Customer Service 5,804,605
Post-sale support — service and support desks, call center operations, customer success and customer experience. A high-headcount function, which makes it useful for seat-based software but noisy for executive outreach.
Titles: Customer Service, Customer Success, Call Center Agent, Call Center Manager, Call Center Trainer, Customer Experience, Call Center Director, Call Center Supervisor…
Media 5,783,217
Content production and journalism: editorial, reporting, broadcast, video and audio production, photography and camera operation. Concentrated in publishing, broadcast and production companies.
