Best B2B paid media agencies (2026): LinkedIn, Google, and paid social for B2B SaaS

These agencies run paid search and paid social across Google, LinkedIn, Meta, and Reddit, mostly for software companies. They are the right call when paid is your main channel and you need a team running it every week.

These sell paid media as one part of a larger program that can include positioning, content, SEO, RevOps, and creative. They fit companies that want one partner owning the whole marketing engine, and they cost more.

LinkedIn is the most expensive ad platform most B2B teams use and the easiest to waste money on. A specialist knows the targeting, bidding, and thought leader ad formats well enough to justify the fee.

Pick on the channel first. If most of your budget goes to LinkedIn, a LinkedIn specialist will usually beat a generalist. If you need Google, LinkedIn, and Meta run together, pick a multi-channel SaaS shop. If you also need positioning, content, and a marketing leader, a full-funnel agency fits better, at a higher fee.

Then ask how they prove results. Any agency can report clicks and form fills. You want one that reports opportunities and pipeline from your CRM, by campaign.

Fees come in three shapes. Flat retainers, like GrowthSpree's month-to-month fee. Spend-tiered retainers, like SaaS Hero's $4,500 to $15,000 per month by ad budget. And percentage of spend, like B2Linked's 20% down to 6% above $15K a month. Most add a setup fee and a 3 to 6 month minimum.

Budget for media on top. LinkedIn clicks are expensive, so a test usually needs several thousand dollars a month in spend before you can judge it. Full-funnel programs such as Refine Labs start at $14,000 a month in fees alone.

Paid ads warm up an account. Outbound books the meeting. Running them on one target account list means the buyer has seen your ads before the first email lands, and the ads keep running while the sequence plays out.

OneGTM does the outbound half: building the account and contact list, finding buying signals, and running email and LinkedIn sequences. The same enriched list can be uploaded as a matched audience for your paid agency, so both channels target the same buyers. See our outbound agency page for how that works.

A paid agency fills the top of the funnel with ad impressions and clicks. Many accounts that see the ads never fill out a form. Outbound reaches those accounts directly.

OneGTM builds the outbound and signal side: account lists, enrichment, signal-based sequences, and matched audience files your paid agency can use. We do not run ads.
