SLSBMB AI vs hiring an SDR
An SDR is a person who researches prospects, writes and sends outreach, and books meetings. SLSBMB AI automates the research, writing, contacts and sending, and hands the replies to you.

Side by side
| In-house SDR (US) | SLSBMB AI | |
|---|---|---|
| Cost | About $95,000–$135,000 a year fully loaded: salary and commission (median on-target earnings $80,000 in 2025), benefits, tools, data and management time | $500 one-time playbook, then a Sending Engine budget from $800 a month ($9,600 a year at the entry), contacts included |
| Time to first output | Hiring, then about 3 months of ramp | Playbook in a few hours; first campaign emails around day 22 after payment, once new inboxes are warmed |
| Research | The rep's own time per account | Specialist AI agents read your site and 50–80+ public sources and map every audience |
| Volume | Limited by one person's day | 120 campaign emails a day at $800, up to thousands a day at higher budgets |
| Conversations | Qualifies replies, calls, books meetings | Reads and sorts every reply; warm ones come to you with a drafted answer |
| Turnover risk | Average tenure about 1.9 years, and what the rep learned leaves with them | None: the methodology stays in the machine |
Ramp, tenure, quota and on-target earnings are from the Bridge Group's 2025 SDR Metrics report, checked on 30 October 2026. The fully loaded cost is a range from published 2026 benchmarks (StealthAgents, Albatalent, Gangly), checked on 12 October 2026; treat it as an order of magnitude.
What one meeting costs
The Bridge Group's 2025 report puts the median SDR quota at 10 held meetings and 6 converted opportunities a month, about 40% lower than in 2018, and only 60% of reps reach it, the lowest share in the study's history. At $95,000–$135,000 a year fully loaded, a rep who hits quota costs the company roughly $790–1,130 per meeting held and $1,320–1,880 per opportunity.
For comparison, at $3,000 a month the Sending Engine runs 40 inboxes and plans about 264 replies a month from month three, with contacts, infrastructure and warmup included. For the yearly cost of one SDR you can run that channel for about three years.
What we learned running SDR teams
We ran outbound with people for 13 years before we built the machine, and the same problems came back every year:
- Quality decays without constant control. A rep starts by spending hours on an email, then an hour, then minutes, and ends up changing two words in a template. Replies fall close to zero.
- Hiring is hard to judge. People who can write to budget owners are rare, and every résumé looks good. Reps move on before closing the deals they warmed up, so the résumé grows faster than the skill.
- The week goes to list building. In our agency years reps spent four and a half days of five finding contacts, leaving almost no time to write. That routine is the first thing the machine took over.
- Management sees problems late. A question about how many inboxes are warmed for a project could take two days to answer, and a mistake found on Wednesday cost a week of capacity.
What SLSBMB AI replaces, and what it doesn't
SLSBMB replaces the parts of the SDR job that are research, writing, list building and sending. It reads your website, interviews you about the offer, researches every audience worth reaching, writes an opener and two follow-ups for each, finds verified business emails, and runs the campaigns from dedicated inboxes at a pace that protects deliverability.
It does not replace a person in the conversation. When someone replies with interest, the reply lands in your SLSBMB AI inbox and CRM with a drafted answer, and you take it from there, whether you are the founder, an account executive or an SDR.
SLSBMB and your sales team together
- No sales team yet? The founder handles the conversations, and the machine produces them.
- Learn which audience answers before you hire for it. The playbook maps every audience; the campaigns show which ones reply.
- Already have reps? Let them spend their time on the people who answered instead of on lists and templates. Predictable cost, no recruiting, ramp or turnover on the outbound side.
Frequently asked questions
Can SLSBMB AI book meetings for me?
No. It finds the people, writes and sends the emails, and sorts the replies. Interested replies are handed to you with a drafted answer, and you book the meeting.
How much does SLSBMB AI cost per year compared with an SDR?
At the $800 entry, the Sending Engine is $9,600 a year plus a one-time $500 playbook, with contacts included in the monthly budget. A 40-inbox engine at $3,000 a month costs $36,000 a year, about a third of one fully loaded SDR. Larger budgets buy more sending capacity on the same public ladder.
Will the emails sound automated?
Each audience gets its own researched opener and two follow-ups in plain text, written for that audience's situation, and the wording varies from email to email so no two recipients get the same text. You can read every email in your playbook before anything is sent, and three complete playbooks are published.
