In the last few months, something quietly remarkable happened in B2B sales. A few of the companies that built their entire businesses on enabling SDR teams — names like Salesloft and Outreach — continued laying off their own SDRs. If that sounds ironic, it’s because it is. It’s like McDonald’s announcing the end of the burger. These are the companies that industrialized prospecting — fueled by sequences, cadences, and dashboards. Now they’re admitting what many of us believed (but got shouted down for saying) – that all their technology enabled people to do was to continue to commit marketing & sales crimes and misdemeanors, just in greater numbers!
I know, I did it
In ’93 (1993, NOT 1893, thanks!) we started a company that was built to do this – outbound B2B lead gen for tech companies, and it was new back then and fabulous! Other things (like email) emerged, but what really put the hammer to it was …you guessed it, everybody’s friend…Offshore. What happened next? The application of technology to compete with cheap labor offshore - the same as is happening now in the manufacturing space. SalesLoft (and the like) convinced companies to use their tech so their SDR’s could make 200 daily calls as opposed to 100 calls. As “lead rates” fall (as people become fatigued with the increasing volume of calls they receive as well as the declining quality ()people who can’t speak English)), then the “promise” of a Salesloft and many others was to enable you to keep cramming bigger numbers at the top. The math was misleadingly simple – when lead rates half, simply make twice as many calls! A race to the bottom.
The False Promise of the SDR Machine
The Sales Development model was, for a while, the closest thing to a religion in SaaS. Hire a small army of young, ambitious SDRs. Arm them with sales tech, email automation, and phone-dialing software. Then measure them — mercilessly — on volume.
More calls. More emails. More sequences. Because, as the logic went, “sales is a numbers game.” Except… the math stopped working. (never worked.) Buyers installed spam filters, ignored cold calls, and tuned out generic outreach. SDRs became noise machines — activity-rich, outcome-poor.
The tools that promised efficiency delivered fatigue — both for the prospects and the SDRs themselves. The model started to resemble a treadmill: lots of motion, very little progress.
Even worse, the function began cannibalizing trust. The more automation crept in, the more robotic outreach became — until prospects stopped answering altogether. And now, the irony is complete: the companies that powered that model are abandoning it internally.
AI Blows Up the Math
The arrival of AI has been like pulling the plug on a faulty machine. Suddenly, sellers can do what used to take entire teams weeks. And they can do it better, faster, and with infinitely more context and relevance.
In other words, AI doesn’t just make prospecting faster — it makes random prospecting obsolete. It actually delivers real personalization, at (more) scale. In other words you can now achieve something that was a contradiction!
The Return of the Self-Sufficient AE
The pendulum has swung back to where it arguably always should have been — to the Account Executive who owns both creation and conversion. But this isn’t the “lone wolf” AE of the past. This is an AI-augmented AE — a seller who uses technology to exponentially increase their capabilities. Want a visual? Think Sigourney Weaver in Aliens, Tom Cruise in Edge of Tomorrow and Matt Damon in Elysium.
The emerging AE doesn't rely on inbound lists or SDR hand-offs. They use AI to surface insights, build narratives, and leverage context. They sound human because they are human — supported by tools that understand details and nuance. And in crowded, loud, homogeneous markets its ALL about details and nuance.
In this model, business development doesn’t disappear. It becomes part of the AE’s rhythm — a seamless blend of discovery, preparation, and engagement. The difference is that machines do the mining; humans do the meaning.
What Business Development Really Means Now
The phrase “business development” came to mean volume. An arbitrary number of opens, click, dials, touches led to “leads” and meetings booked. Now it’s about value discovery — finding where your offer intersects with a prospect’s opportunity or threat.
It’s not about who can contact more people. It’s about who can contextualize faster.
And that’s exactly where well applied AI excels.
AI can digest a target account's information, find and connect synergies and contextualize this across the landscape. That's not so much personalization as it is relevance. We've moved from the information age to the interpretation age. It doesn’t mean no one picks up the phone anymore. It just means they do it at the right time, for the right reason, and with something righteouse to say!
The ADR Era
So, if the SDR is fading, what replaces it? Maybe it’s something new: the ADR — AI (enabled) Development Representative.
An AI-driven system that:
Researches markets and accounts.
Flags opportunities based on synergies and timing.
Drafts smart, relevant outreach communications.
Hands the human a complete, contextualized picture of an opportunity.
The ADR doesn’t send 1,000 emails. It identifies the five conversations worth having, and gets the AE prepared faster and smarter. And in that world, “business development” doesn’t vanish — it finally grows up.
Full Circle
Ironically, this evolution brings B2B sales back to where it began. real people, having real conversations, about real business problems. When I started in this business sellers were responsible for their own prospecting right way through to their own closing – from first call to final close. The difference now is that the preparation is automated. AI doesn’t replace the human; it redeems them from bad process.
Maybe that’s the final twist in this long story. The SDR era didn’t die because of technology. It died because of its own lack of humanity. And AI — the very thing people feared would make sales less human — might be what makes sales more human…again.
