Is an AI sales agent really cheaper than hiring an SDR?

Yes, by an order of magnitude on subscription cost. A fully-loaded US inside-sales rep typically runs $130,000–$175,000 a year (base, commission, benefits, tooling, ramp loss, management overhead). Sally by SallySells ranges from $11,808/yr (Core, annual prepay) to $41,988/yr (Growth, monthly), plus a 10% performance fee only on closed deals. Net savings against a single SDR: $115,000–$138,000 a year depending on tier.

Can an AI sales agent really replace a human SDR?

For top-of-funnel work — inbound lead response, multi-touch follow-up, qualification, and demo scheduling — yes. A full-cycle AI sales agent (like Sally) goes further: she also delivers the live product demo, handles objections, and progresses the deal to ready-to-sign. Humans still close: contract negotiation, pricing edge cases, and signature stay with people by design. Most teams use an AI agent to multiply a small human sales team rather than fully replace it.

How fast does an AI sales agent respond compared to a human SDR?

Sally responds in under a minute on every lead, 24/7/365. The average human B2B response time is 29 to 42 hours. 63% of B2B companies never respond at all. Leads contacted within five minutes are roughly 100× more likely to qualify than those reached after 30 minutes — and only 0.1% of B2B companies hit that five-minute bar.

What about ramp time?

A new SDR takes 3–6 months to become fully productive and reach quota. Sally goes live in under a week — record your pitch once, hand her your deck and an inbox. She is working leads by end of week, in your voice.

What does an AI sales agent NOT do that a human SDR does?

Final pricing negotiation past the standard discount band, contract redlines, legal review, and signature stay with humans. Truly novel relationship-building — conferences, dinners, the prospect who only buys from people he golfs with — also stays with humans. Sally handles the volume work that scales linearly with pipeline; humans handle the deal-by-deal nuance at the close.

The three numbers that decide the comparison

1. Speed-to-lead. The most rigorously measured statistic in B2B sales: a five-minute first reply makes a prospect roughly 100× more likely to qualify than a 30-minute reply. The industry-average human response time is 29 to 42 hours. Only 0.1% of B2B companies are inside the five-minute window today. Sally is inside it on every lead, structurally.

2. Follow-up completion. 80% of B2B sales require five or more follow-ups. 92% of human reps give up before the fifth touch. 93% of converted leads are reached on touch six or later. Sally runs the cadence on every thread, every time, without fatigue or forgetting.

3. Fully-loaded cost. A single US SDR at SMB-loaded cost runs $130,000–$175,000 a year. Sally's annual subscription range is $11,808 to $41,988 (Core through Growth on annual prepay), plus 10% of Year 1 value on each deal she drives to ready-to-sign. The breakeven point against one SDR is well under one closed deal a year for most B2B price points.

When a human SDR is still the right answer

Hire a human if the buying motion depends on in-person presence — conferences, executive dinners, on-site evaluation. Hire a human if your deals are seven- and eight-figure enterprise sales where the relationship is the product. Hire a human if you sell into a regulated industry where every conversation must be conducted by a licensed professional. Outside those cases, hiring an additional SDR in 2026 is the more expensive of the two options for the same body of work.

How most teams actually deploy Sally

The most common configuration we see is not "AI replaces all humans." It is "AI handles the volume; humans handle the close." Sally takes over inbound response, follow-up, qualification, demo delivery, and outbound sourcing on Growth+. The human team focuses entirely on the deals Sally has progressed to ready-to-sign: pricing nuance, contracts, signature. A two-person sales team operating with Sally can run the inbound and outbound workload of a six- or eight-person team.
