AI SDR / Fractional Growth

Most teams buy an AI SDR tool, watch it fire 5,000 emails, and book three meetings. The tool was never the problem. The system around it was. As an AI SDR consultant, I do not sell you software. I build the pipeline machine that the software runs inside: the data, the targeting, the offer, the sequencing, and the human handoff that turns a reply into a closed deal. Volume without a system is just noise that burns your domain reputation.
I am Yaniv Goldenberg, a Fractional Head of Growth. I have managed $100M+ in budgets, and I treat outbound the same way I treat paid media: as a measurable revenue channel, not a spray of activity. An AI SDR consultant who only counts sends is selling you the wrong metric. I count booked meetings, meeting-to-opportunity rate, and pipeline value per domain. Those are the numbers that pay your sales team and keep your CFO calm.
The work starts with your ideal customer profile, not your email copy. I rebuild your target list from firmographic and intent signals, strip the dead accounts, and segment by the specific pain each tier feels. AI writes faster when it writes to a tight segment. A generic prompt produces generic email, and generic email gets ignored. Tight inputs produce sharp outputs. That is the whole game, and it is where most AI SDR deployments quietly fail before the first send.
Deliverability is the second pillar, and it is where I spend real time. I set up dedicated sending domains, warm them properly, enforce SPF, DKIM, and DMARC, and cap daily volume per mailbox so you land in the inbox instead of the spam folder. Google and Microsoft now enforce hard sender requirements, and you can read them straight from the source in the Google email sender guidelines. An AI SDR consultant who ignores this hands you a dead domain in six weeks. I have rescued accounts that hit exactly that wall.
Then comes the AI layer itself. I configure the models to research each account, draft personalized first lines that reference real triggers, and run reply classification so your reps only touch warm conversations. The AI drafts; a human approves the offer logic. I keep that boundary firm because automated replies that hallucinate a feature or a price destroy trust faster than any cold email ever could. The goal is use on the boring 80 percent, with human judgment reserved for the 20 percent that closes.
I have done this scale work in product growth too. I took Elementor to 100x ARR by treating every channel as a funnel with a fixed conversion math, and the same discipline applies to outbound. Reply rate times qualification rate times close rate times average deal size gives you a single revenue number per sequence. Once you can see that math, you stop arguing about subject lines and start fixing the step that actually leaks. That clarity is the real product an AI SDR consultant should hand you.
If you want outbound that produces pipeline you can forecast, not a dashboard full of opens, that is the engagement. I scope a 30-day build, prove the system on one segment, then expand to the segments that hit your cost-per-meeting target. From traffic to revenue, the principle holds: measure the dollar, not the activity.
The tool sends email. I build the system the tool runs inside: the target list from intent signals, the deliverability setup across dedicated domains, the segment-specific offers, and the human approval layer. Tools optimize sends. I optimize booked meetings and pipeline value. Buying the software without the system is why most teams book three meetings off five thousand emails.
I use dedicated sending domains separate from your main one, warm each mailbox before volume ramps, and enforce SPF, DKIM, and DMARC. I cap daily sends per mailbox and monitor bounce and spam rates weekly. Google and Microsoft now enforce hard sender requirements, so I build to those rules from day one instead of rescuing a burned domain later.
More than a generic merge field, less than a fully human-researched note, if you feed it tight inputs. I configure the model to research each account and draft a first line referencing a real trigger like a hire, funding round, or product launch. The AI drafts; a human approves the offer logic. Sharp segment inputs produce sharp output. Generic prompts produce ignored email.
Booked meetings, meeting-to-opportunity rate, and pipeline value per sending domain. The core equation is reply rate times qualification rate times close rate times average deal size, which gives one revenue number per sequence. Once you see that math you stop arguing about subject lines and fix the step that actually leaks. Sends and opens are vanity; they do not pay your sales team.
I scope a 30-day build: rebuild the target list, set up and warm domains, configure the AI layer, and launch on one segment. You see real replies and meetings inside that window, not just a live dashboard. Then I expand only to the segments that hit your cost-per-meeting target. I prove the math on one slice before spending budget to scale the rest.
A wave of AI SDR products promises a robot that books meetings while you sleep. Most are closed platforms that blast generic AI-written emails at scale, which is the fastest way yet invented to torch your domain reputation and annoy your market. You pay a steep subscription, you do not own the logic, and when results disappoint you cannot see why or fix it.
The version that works treats AI as the research and drafting layer inside a system you control, not an autonomous spam cannon. Agents handle the heavy lifting: pulling account signals, personalizing the angle, sequencing the follow-up. A human reviews quality and approves the messages that need judgment. You get the leverage of automation without surrendering the relevance and reputation that make outbound work at all.
An AI SDR system is one capability inside a growth engagement, not a standalone product I sell you a seat to. As your fractional head of growth I make sure the agents target the right ICP, feed the same pipeline as your other channels, and stay measured against real opportunities. The system is built on infrastructure your team owns and can extend.
Agents that pull account signals, enrich contacts, and assemble the context a good rep would gather before reaching out.
Claude-powered drafting that personalizes each message to the account’s real signal, not a mail-merge token.
Approval gates so a person reviews quality and judgment calls before anything sends. Automation does the volume, humans guard the standard.
Sending infrastructure, warmup, and sequence logic wired in n8n, so the engine scales without burning your domain. See n8n automation.
This is the strongest reason to build with me rather than rent a closed AI SDR tool: I dogfood the stack. My own marketing operation runs on n8n for orchestration, the Claude API and Claude Code for agent work, and Postgres for the data layer, with self-hosted deployment I control. I build and debug AI agents on this stack daily for content, research, reporting, and AI-search monitoring. When I build your AI SDR system, I am handing over patterns I depend on in production, not a demo I assembled for a sales call. The build story behind one of these agents is on the Claude Code SEO and GEO skill page.
Signal-driven, not volume-driven. The agents act on the same signal-based logic as good human outbound: fewer, better accounts with a relevant reason to reach out now. See outbound.
Human approval where it counts. Agents draft and sequence; a person approves anything that needs judgment. That keeps quality high and stops the system from sending something that damages the brand.
Owned infrastructure. Built on your n8n, Claude API keys, and database, so the logic is readable and the data is yours. No vendor lock-in, no per-seat tax that scales against you.
Deliverability discipline. AI does not get a pass on reputation. Separate domains, authentication, warmup, and capped volume apply exactly as they would for human-run outbound.
Measured on pipeline. Success is qualified opportunities, not emails sent. The agents are tuned to reply quality and meeting-to-pipeline, and I cut what does not convert.
Outbound already fits your model, you have a defined B2B ICP, and you want to scale the research and drafting load without proportionally scaling headcount, while keeping a human on quality.
Outbound itself is not your channel, or you expect a fully autonomous robot with no human oversight. Hands-off AI outbound at volume is how domains get burned and brands get hurt.
If you do not yet have outbound working with humans, I will tell you to prove the motion first. AI scales a system that works; it does not rescue one that does not.
I combine growth-operator experience with a stack I run myself. I led acquisition at Elementor from roughly $200K to over $20M ARR between 2018 and 2020 as it passed five million users. I led growth at cnvrg.io, an MLOps platform built for exactly the technical B2B buyer AI SDR systems serve, ahead of its acquisition by Intel announced in November 2020 (TechCrunch). I drove 337% MRR growth at Riverside. And I build AI agents on n8n and Claude every day for my own business. See the cnvrg.io case study and AI marketing.
A system of agents that research accounts, draft relevant outreach, and manage sequences automatically, with a human approving the work that needs judgment. It is leverage on the research and drafting load, not a fully autonomous robot.
Most are closed platforms that blast generic AI emails and lock you in. I build on your own n8n, Claude API, and database, so you own the logic and data and a human stays on quality.
Yes. My own marketing runs on n8n, the Claude API, Claude Code, and Postgres. I build and debug these agents in production daily, so the patterns I hand over are proven, not demoware. See the Claude Code skill.
Yes, by design. Agents draft and sequence; a person approves anything needing judgment before it sends. That keeps quality high and protects the brand.
Only if it is run as a hands-off spam cannon. I apply the same deliverability discipline as human outbound: separate domains, authentication, warmup, and capped volume.
Ideally yes. AI scales a motion that already works. If outbound is not yet proven with humans, I will tell you to validate it before automating. See outbound.
You do. It is built on your infrastructure and documented so your team can run and extend it. No vendor lock-in and no per-seat tax that scales against you.
A fixed-scope diagnostic sprint runs $6,000 to $8,000. Infrastructure builds start at $5,000 per month. A full embedded operator engagement runs $8,000 to $18,000 per month.
An AI SDR system can be advised on, built as owned infrastructure, or run as part of a fractional operator role.
2-4 week audit of your growth stack plus a 90-day roadmap. Fixed scope, converts to a retainer.
Full fractional role with the AI SDR system owned alongside the rest of growth. See fractional CMO.

Buying 11x or Artisan or a Clay seat is not a pipeline. It is a fast way to send bad email at scale. The job of an AI SDR consultant is to make the autonomous part earn its autonomy: tight targeting, real signals, and copy a human would not be embarrassed to send. The software is the easy 20 percent.
I start with the signal layer, not the send. An AI SDR consultant who has run growth knows that the account list is the campaign. Funding rounds, new hires in the buying role, tech-stack changes, job posts that imply a pain you solve: those are the triggers that make outbound feel timely instead of random. Clay enriches and routes; the agent only fires when a real reason exists.
The second build is deliverability discipline. Autonomous volume kills domains when nobody is watching. I separate sending domains from your primary, warm them properly, cap daily volume per inbox, and watch reply and spam rates like a dashboard, not a quarterly report. An AI SDR consultant who skips this hands you a burned domain and a tool subscription.
Third is the human checkpoint. Fully hands-off outbound reads like a robot and converts like one. I keep a person on the first-touch angle and the reply handling, and let the agent do the repetitive enrichment, sequencing, and follow-up. That split is where an AI SDR consultant actually saves you headcount without torching the brand.
The last piece is honest measurement. Booked meetings that show up and turn into pipeline, not opens and clicks. I wire the replies back to the CRM, track meeting-held and opportunity rates by segment, and kill the segments that look busy but never close. If a list is not producing, an AI SDR consultant says so and reallocates instead of defending the spend.
If you want an AI SDR consultant who treats autonomous outbound as a system to engineer rather than a button to press, that is how every engagement runs.
