Performance marketing, agentic automation, and a painter's eye — in one person.

Most marketers can't design. Most designers can't run acquisition. Almost no one wires the automation. I do all three — and I'm making it run itself.

It's my voice, cloned. Ask the concierge anything about the work — it'll tell you what it doesn't know.

The concierge is warming up. In the meantime, the work speaks for itself below — or reach out directly via the contact links.

The approach

01

I come at growth from two directions most people never combine.

A quarter-century of painting and a decade inside the art world taught me to judge whether a thing is any good — the taste half. Performance marketing taught me to prove it with money and data — the rigor half. Because I build the automation layer myself, the two stop being a handoff between departments: a creative call becomes a test, a test becomes a workflow, and the workflow runs without me.

That last part is where most of my time goes now — turning the parts of marketing that used to need a person into agents that don't.

A concierge that speaks in my voice

ElevenLabs voice agent, n8n lead capture

Live proofYou're using it right now.

The audio guide on this page is the case study. It's a transparent AI concierge — my cloned voice, but it introduces itself as an assistant, never pretends to be me. It answers recruiters' and clients' questions from a grounded knowledge base, and when it doesn't know something it says so and points to the contact links rather than improvising.

Why it matters: the thing I'm selling — voice, agents, and n8n automation — is demonstrated by the medium you're hearing it through.

How it's built
Instant Voice Cloning on ElevenLabs, running on the low-latency Flash model for real conversation. The agent is grounded in a curated Q&A knowledge base and hard-instructed not to speculate about my experience. Every conversation can hand a lead to an n8n flow that logs to a CRM and offers to book a call — the same autonomous loop I build for clients.

Reading an account against its own assumptions

Paid acquisition & creative analysis — European telehealth (client anonymized)

Outcome3 targeting beliefs overturned by the data

A go-to-market and creative audit for a telehealth brand entering a new market. The interesting part wasn't the plan — it was where the campaign data flatly contradicted what everyone assumed was working:

  • Static creative beat UGC on share of genuinely new customers.
  • Broad targeting beat lookalikes — the "safe" audience was the expensive one.
  • Hook rate barely correlated with acquisition — the vanity metric wasn't the buying signal.

The deliverable: a UGC scoring rubric and a media read that told the client which of their beliefs the numbers didn't support.

Method & framing note
Presented as approach and analytical calls only — the client's brief, names, and raw data are withheld. The value on display is the diagnostic method: isolating new-customer share from re-engagement, separating creative-attention metrics from purchase behaviour, and pressure-testing targeting orthodoxy against spend.

Lead response, fully automated sample — swap in a real flow

n8n workflow, enrichment & routing

Result4 hours → 90 seconds

The clean flow above is the entry point — never a raw n8n canvas. The narrated Loom sits behind the poster and plays on click.

Technical detail
Placeholder copy for the engaged evaluator — replace with a real shipped flow. Redaction reminder before recording: scrub every API key, webhook URL, token, and client name from node configs and execution payloads, and don't read any of them aloud in narration. Record against dummy data or a pre-redacted canvas.

What I can build for you

03

Agentic marketing automation

n8n workflows that qualify, route, and follow up on leads on their own — the boring middle of your funnel, running without you.

Paid acquisition & creative testing

Campaigns set up, measured, and read for what actually drives new customers — not the metrics that only look like progress.

AI voice & agent builds

Grounded, on-brand voice and chat agents — like the concierge on this page — with cost caps and honest "I don't know" behaviour built in.

Growth analysis

An audit that tells you which of your assumptions the data doesn't support, and what to do about it.

The path here

04

I started as a painter, and I've never stopped.

Twenty-five years at the easel, an MA in contemporary art from Sotheby's Institute in New York, and a run directing a contemporary gallery in Tel Aviv taught me the part of this work you can't A/B test: whether something is actually any good. Alongside it, a computer science degree from IDC Herzliya gave me the other half — I could always build the thing, not just brief it.

Those two tracks stayed separate for years until performance marketing turned out to be where they finally met: a discipline that rewards taste and demands proof, and that increasingly runs on the exact automation I like to build. So that's what I do now — sit at the seam between the marketer, the builder, and the artist, and make the machine in the middle run itself.
