Is it cheaper to hire an SDR or pay a lead gen agency?

Depends on stage. Under $5M revenue — agency is almost always cheaper. You get access to an expert system without paying for a full-time salary, benefits, management time, and tool stack. Over $15M revenue — in-house starts making sense because volume justifies building the capability internally. Between $5-15M, it depends on whether lead gen is a strategic core competency or a commodity.

Can I just build lead gen myself with AI tools?

Technically yes — the tool stack (Apollo, Clay, Smartlead, OpenAI, n8n) is available to anyone. Practically, most founders fail at it. The tools take 60-100 hours to learn well. Sequencing, deliverability, signal selection, reply handling are all deep skills. If your time is worth more than $200/hr, buying expertise is cheaper than building it.

What's the typical SDR salary vs agency retainer?

US SDR: $55-85K base + $25-40K commission + $15-20K benefits + $10-15K tools/management = $105-160K total loaded cost. Agency retainer for equivalent output: $2-6K/mo = $24-72K/year. Agency is typically 40-70% cheaper while delivering comparable or better results (at the agency's specialization).

Build vs Buy Lead Gen: The Real Cost Math (In-House SDR vs Agency vs DIY)

Every B2B founder eventually faces the same question: “Should I hire an SDR, outsource to an agency, or just build lead gen myself?”

Here’s the honest cost math at three company stages — plus which path actually makes sense when.

The Options Defined

Three paths to generate pipeline:

In-House SDR — You hire 1-3 full-time SDRs who prospect, email, call, and book meetings.
Lead Gen Agency — You pay an outside team to source, qualify, and book on your behalf.
DIY with AI Tools — You (or someone on your team) learn the stack (Apollo, Clay, Smartlead, etc.) and run it yourself.

Each has a different cost structure and a different skill requirement.

Full Cost Breakdown: In-House SDR (US-Based)

Line Item	Annual Cost
Base salary (SDR, 1-2 years exp)	$55,000 - $85,000
Commission (typical 30% of base at quota)	$20,000 - $40,000
Benefits + taxes (employer load)	$15,000 - $25,000
Tool stack (Salesforce/HubSpot, Apollo, LinkedIn Sales Nav, Outreach/Salesloft)	$8,000 - $15,000
Management time (director/manager oversight, 10-15% of their time)	$15,000 - $30,000
Training + ramp (3-6 month ramp to productivity)	$15,000 - $25,000
Total annual, Year 1 fully loaded	$128,000 - $220,000

For one SDR producing 8-15 meetings/month at scale.

Full Cost Breakdown: Lead Gen Agency

Line Item	Monthly	Annual
Setup sprint (one-time)	$2,500-$10,000	—
Monthly retainer	$1,500-$7,500	$18K-$90K
Performance bonuses (optional, per meeting)	$100-$300/meeting	$10K-$40K
Ad spend (if running paid channels, passed through to client)	Varies	Varies
Total annual (excluding ad spend)	—	$28,000 - $130,000

For agency producing 20-60 meetings/month at scale — typically 2-3x more output than a single SDR, at 40-70% lower cost.

Full Cost Breakdown: DIY With AI Tools

Line Item	Cost
Apollo / Clay enrichment	$1,200-$4,800/year
Smartlead or Instantly	$1,200-$3,600/year
LinkedIn Sales Navigator	$1,200/year
AI (GPT-4o, Claude) API usage	$2,400-$6,000/year
Warmup tools, CRM, n8n, misc	$1,800-$3,600/year
Tool stack total	$7,800 - $19,200/year
Learning curve (60-100 hours ramp)	Opportunity cost
Ongoing time (10-20 hrs/week to run)	Opportunity cost

Looks cheap on paper. Hides two big costs: the 60-100 hour learning curve and the 10-20 hours per week to maintain the operation. If your time is worth $200/hr, you’re spending $100-200K in opportunity cost annually to save $50K in agency fees.

What Actually Makes Sense When

Stage 1: Revenue Under $2M/Year

Skip in-house entirely. Don’t hire SDRs. You can’t afford the $150K loaded cost and the 6-month ramp time.

Agency is the clear win. $30-60K/year agency = experienced system, no ramp, results in 4-6 weeks. If it doesn’t work, you can fire them in 30 days. Firing an SDR takes legal paperwork.

DIY only if: You genuinely love lead gen work, have 15+ hours/week to learn it, and view it as a strategic skill to own long-term. Most founders at this stage don’t.

Stage 2: Revenue $2-10M/Year

Hybrid works here. Keep the agency running your core outbound channels. Consider hiring 1 SDR to focus on a specific high-value vertical or account-based motion.

Pure in-house still too expensive. One SDR = $150K. Two SDRs + manager = $400K+. You’re better off with an agency spending $60-90K on broader coverage + 1 SDR focused on high-value accounts.

Stage 3: Revenue $10-25M+/Year

Now in-house starts to pay off. You have volume to justify 2-4 SDRs + a manager. You want lead gen as a core capability, not an outsourced function. You can afford the infrastructure.

Keep agency for channel expansion. Even with in-house, many companies keep an agency running a secondary channel the in-house team doesn’t master (e.g., LinkedIn while SDRs do email + cold calling).

Stage 4: Revenue $25M+/Year

Full in-house team. 4-10 SDRs, dedicated manager, ops lead, content creator for outbound. Agency becomes redundant except for very specialized campaigns.

The Hidden Cost Most Miss

When comparing costs, founders usually miss: time-to-productivity.

SDR hire: 90 days to become productive, 6 months to hit quota. 4 months of wasted salary during ramp.
Agency: 14 days to first campaigns live, 4-8 weeks to stable pipeline. You pay for results, not ramp.
DIY: 60-100 hours of learning + 2-3 months of sub-optimal execution while you figure out what actually works.

For most companies under $10M revenue, agency is the fastest path to pipeline. Period.

What PromptShift Charges

Since you’re asking: our pricing lives on the agency side.

Setup sprint: $2,500-$10,000 one-time (depends on channel complexity + setup needs)
Monthly retainer: $1,500-$7,500/mo (depends on # of active channels)
Performance bonus: Optional $100-$300 per qualified meeting booked
Solo operator model: I personally run every campaign. No account manager layer.

For most clients, total monthly commitment is $3-6K. For that, you get a working outbound system producing 20-60 qualified meetings per month — vs. $12-17K/month loaded cost for equivalent in-house output.
