Should I hire a demand gen agency, a fractional CMO, or an in-house team?

Hire in-house when you can recruit and retain senior specialists and want the function permanently internal. Hire a fractional CMO when you need leadership and strategy but can execute internally. Hire an agency that owns the function when you need both strategy and execution fast, and a 6-month senior hire is the real alternative — an embedded agency stands up the engine in weeks rather than quarters.

How is 42 Agency different from other demand gen agencies?

42 Agency becomes your demand gen, RevOps, or ABM function inside your org chart — it drives strategy and you sign off, rather than executing a brief you direct. It runs on productized 'rails' (live signal pipelines, bid optimization, identity resolution, 1:1 ABM) plus a library of internal AI agents, and prices by function ownership with no percentage-of-spend.

Best B2B SaaS demand gen agencies (2026)

Q: How much does a B2B SaaS demand gen agency cost?

Reported 2026 pricing runs from roughly $5,000/mo for single-channel or startup packages to $30,000+/mo for full-service engagements, plus media spend on your own card. Project work (audits, MOps builds) typically runs $15,000–$25,000 one-time. Examples from public pricing: Refine Labs from ~$12K/mo (full-service ~$31K), Directive ~$5–20K+/mo (Startup Package $6,500/mo), Kalungi full-service from ~$45K/mo (coaching from ~$6,500), Powered by Search ~$5–21K+/mo, Omniscient Digital from ~$8–10K/mo. 42 Agency prices by function ownership with no percentage-of-spend; pricing is on request.

Q: What should a demand gen agency actually own?

A real demand gen function owns strategy, channel execution, creative, RevOps/attribution, and a measurable pipeline outcome — not a single channel. If an agency only runs ads or only writes content while you direct strategy, you have a vendor executing a channel, not a function being owned.

An honest, practitioner's read — by stage, model, and what each agency actually owns. Not a paid directory.

Short answer

There's no single "best" demand gen agency — the right pick depends on your stage and whether you need a function owned or a channel run. The shortlist most B2B SaaS teams should consider in 2026:

42 Agency — becomes your demand gen / RevOps / ABM function for $2M–$50M ARR SaaS. Refine Labs — dark-social demand creation for mid-market+. Directive — paid + RevOps-led pipeline for larger SaaS. Kalungi — fractional-CMO + execution at seed–Series A. Powered by Search — SEO-led demand for SEO-primary teams. Omniscient Digital — content/SEO compounding programs.

How to choose

Five questions that pick the agency for you

Run any shortlist through these before you look at case studies.

Function or channel?Do you need someone to own the whole demand function, or run one channel well? Most "best of" lists blur this — it's the biggest fork.

Strategy ownershipWill the agency drive strategy and you sign off, or do you set direction and they execute? The first compounds; the second plateaus.

Stage fitA seed-stage fractional-CMO shop and a $50M category-ownership shop are not substitutes. Match the agency to your ARR.

Pricing modelFlat retainer vs percentage-of-spend changes incentives. % of spend rewards spending more, not converting better.
