Why me

Compared to your other options

Early-stage B2B marketing is its own discipline, not a smaller version of the enterprise kind. It is the only thing I do.

A CMO hire

Expensive, senior and used to directing a team. It takes months to hire one, and most have not done the hands-on work themselves in years. You are paying for management before you have anyone to manage.

Founder CMO $$$$ nobody to direct yet Manages the work, does not do it

Agency

You buy the pitch from the senior partner. The work drops to a chain of junior writers, designers and ops. You meet the top; the bottom does the building.

Juniors you never meet Founder Accountlead A "team". Mostly juniors.

Junior hire

A first marketing hire is often early-career, learning the senior playbook on your runway. Cheap and versatile up to a point, but it means junior output, little strategic thinking and long turnarounds.

Doing it yourself with AI

What is the real cost of the wrong marketing decisions, compounded over a year? AI is fast and cheap, and it applies best practices with no read on your market. Plenty of output, none of it decided.

Founder + AI ? Plenty of output. No judgment. Output without judgment

How I work

Diagnosis first

I don't guess, and I don't write a proposal off one call. Every engagement runs the same three phases, and no monthly number goes on work I have not scoped yet.

Phase 1
Plan, the diagnostic

A week or more into your product, market, and funnel. I find what is actually holding growth back, review your positioning and tools, and map the plan to your next milestone.

The required first step. The plan is yours to keep.
Phase 2
Build, the infrastructure

Once the plan is clear, I build. A focused sprint that sets up the core: positioning and messaging, the systems and workflows, and the material your sales needs to close.

You get a working marketing engine.
Phase 3
Run, fractional leadership

A system needs a driver. I own the marketing function, guide whoever executes, and keep it scaling toward the next round. How much I run and how much your team takes, we settle once the plan makes it concrete.

You get a function that runs without you in it.

Mentoring

One on one with your founders

Standing office hours or a fixed number of sessions. Founders bring whatever is actually stuck that week and leave with a call they can act on.

"With Ami I had a partner I wasn't ashamed to go through the basics with, and a mentor who gave detailed feedback on real projects. He was a clear sounding board and voice of reason against aggressive targets, and I came away with sharper marketing instincts and a real understanding of how the functions connect."

About

Hi, I'm Ami.

I have spent 17 years in B2B marketing, almost always in setup phases. Some of it launching new products and business units inside growing companies, some of it as the first marketer or head of marketing at early-stage ones.

For the past 2 years I have done that as a founding marketer. Right after a raise, founders need two things at once: the judgment to pick the right move for where they actually are, and someone to get it done. I either do that work or help you do it.

Questions

Before you book

How much of your time do I actually get?

The work is judged on outcomes, but the rhythm is fixed. Every week we meet to review what got done, decide what happens next, and clear whatever is stuck, plus extra sessions on specific topics or with specific people when they are needed. Between meetings we run over email, and I reply within a day. Responsive, not on call.

How many founders do you work with at once?

No more than 4 as a founding marketer, and often fewer, depending on how involved each engagement is. Whatever else I am running, a founding-marketer client gets at least one full day of my week.

What is the minimum commitment?

None beyond the prepaid monthly invoice. No lock-in, no notice period. I will say plainly that both paths need at least 3 months before the results are worth judging, so it is worth starting only if you can give it that.

What is actually included, and what do you hand back to me?

We scope it before anything starts: the categories of work, the goals and milestones, and the final price all get set in that first step. Whatever the mix, design, content, paid, PR, vendors, I own it end to end.

I build the infrastructure and run and refine the first processes until growth is steady, then hand it to your in-house marketer. Everything is documented, from SOPs to repositories, so the handover is clean.

Advisory or founding marketer, and can I move between them?

They fit 2 different situations. Advisory is for when someone on your team already owns the hands-on execution and needs direction and review. Founding marketer is for when I am the marketing team, from strategy through vendor management to execution.

As you hire or restructure internally, we can shift from one to the other, and I will help make that transition work.

Who pays for tools and ad spend?

Those sit in a separate marketing budget, outside my fee, covering tools, ad spend, and external vendors. We size it to what you actually need and what you can actually spend.

Is my startup the right fit?

The fit is a funded B2B startup with a few real customers, typically over $1M raised. Too early is no customers yet or a budget below that. Too late is when the how is already settled and the job is mostly turning up the volume, usually a large A or a B round.

I stay in B2B, not consumer, DTC, gaming, or crypto, and out of fields that need their own specialist background like insurtech, healthtech, or foodtech. If you are unsure, send the form and we will look at it. I only take work I am confident I can move.

How do we work together day to day?

Remotely, in Hebrew and English interchangeably. If you are in the Tel Aviv area we can meet in person. I can manage vendors in specific areas and work alongside a hands-on marketer on your side, or sit purely in an advisory seat. What I do not do is run under a CMO as their execution team.

What do the first weeks look like?

They start with an assessment, not a plan pulled off a shelf. That is a real piece of work, at least a week of research before I commit to a direction. From there it is usually some mix of rebuilding the core marketing material, testing a couple of channels, and finding the one that shows early, readable results worth leaning into.

Why not just make a full-time hire?

Most early startups hire too soon. They bring on a full-timer before there is a budget to deploy or a clear read on what works in their market, and the first hire often lands too senior, too junior, or out of a different industry. Getting senior judgment on the phase you are actually in, without carrying a full-time salary for it, is the whole point of working this way.
