What is the cost difference between AI SDR and human SDR?

A human SDR fully-loaded (salary + taxes + benefits + tools + recruiting amortization) runs $70,000–$115,000 per year, or roughly $5,800–$9,600 per month. An AI SDR like Velmora costs $299/month — a flat subscription with no per-email fees or seat licenses. That's a 20–32x cost difference for comparable outbound volume.

How does AI SDR personalization compare to a human SDR?

AI SDR tools like Velmora research each prospect — their company, role, recent news, likely pain points — and write a personalized email under 120 words with a curiosity-driven subject line. The output quality is comparable to a skilled human SDR and is consistent across every prospect. Human SDRs are personalization-capable but have off days, context limits (how many prospects they can deeply research in a day), and tenure risk — when they leave, the institutional knowledge leaves with them.

How long does it take for an AI SDR vs human SDR to start producing results?

Velmora is live in one day — add your prospects, the AI researches and drafts the first outreach, you review and send. A human SDR typically takes 3–6 months to reach full productivity: job posting, interviewing (4–8 weeks), onboarding, product knowledge ramp, first sequences, optimization. Most companies see their first meetings from a new SDR hire after month 2 at the earliest.

What are the risks of hiring a human SDR vs using AI SDR software?

Human SDR hiring risks include: high turnover (average tenure is 14 months, meaning you re-hire every 1–2 years), performance variance (some reps hit quota, many don't), management overhead, and ramp cost — you spend 3–6 months of salary before seeing results. AI SDR software risks are lower: technology reliability, email deliverability, and whether the personalization quality matches your brand voice. Velmora mitigates the latter with human review before sending — you approve every email before it goes out.

Q: Should I hire an SDR or use AI?

For most SMBs doing outbound B2B prospecting, AI SDR software is the better starting point. A human SDR costs $65,000–$100,000 per year fully-loaded, takes 3–6 months to ramp, and has a 12–18 month average tenure — meaning high turnover. AI SDR tools like Velmora cost $299/month, start working on day one, and scale to any volume without hiring. The case to hire a human SDR first makes sense only once you have enough qualified pipeline to justify the headcount and a strong onboarding program.
