I’m setting up B2B outreach for IT & telecom services (USA, SMB 10–100 employees) which channel should I focus on first?

I was setting up B2B outreach for an IT & telecom services business targeting the US, and I realized something pretty quickly , choosing the right channel is harder than I expected.

My target is:

Companies with 10–100 employees

Industries: IT services, telecom, SaaS

Roles: founders, sales/marketing heads, IT managers

Budget is limited, so I can’t experiment everywhere at once. I need something that actually brings meetings consistently, not just impressions or clicks.

Here’s where I’m stuck:

Cold email — feels like it can work if targeting + personalization is done properly

LinkedIn outreach — but inboxes seem crowded now

Partnerships/channel sales — seems powerful but slower to set up

Content/SEO — good long-term, but I need traction faster

Paid ads — risky with a small budget

Right now I’m thinking instead of going “multi-channel,” it might be smarter to go deep on 1–2 channels first and get real results, then expand.

Main goal:

Book qualified meetings without burning budget

Would love to hear real experiences:

Which channel worked best for you in early stages?

What did you try that completely didn’t work?

If you had to start again, where would you focus first?
