How to pick the right agency (quick checklist)

• Match experience to your tech sub-vertical (developer tools, enterprise SaaS, cybersecurity, martech, IoT, etc.).
• Decide primary goal: SEO traffic, pipeline generation, product-led onboarding content, thought leadership, or enterprise ABM—agencies often specialize.
• Ask for metrics and case studies that match your company size and funnel stage (MQL → SQL conversion, organic traffic lift, inbound demos).
• Confirm writer/editor technical depth (do they use subject-matter experts or freelancers?) and ownership of distribution (SEO + PR + ABM).
• Budget signal: small boutiques are usually $6k–$15k+/month; mid-market retained programs $15k–$40k+/month; enterprise programs larger and custom. (Get exact quotes.)

Next steps I recommend

• Pick 3 agencies from above that match your size and goals.
• Ask each for: (a) 12-month content plan outline, (b) 2-3 relevant case studies with metrics, (c) team bios for writers/editors, and (d) a sample brief and pricing model.
• Run a short paid pilot (6–12 weeks) to validate creative & execution before committing long term.

If you want, tell me: (a) your company size (ARR or employee range), (b) primary content goal, and (c) monthly budget — I’ll shortlist 3 agencies from the list above and draft specific questions to send them.
