What Good Looks Like in a New Marketing Leader’s First Six Months

The short answer: A new full-time marketing leader should build or test the diagnosis in the first 30 days, own the plan and agree a pipeline target with sales by day 90, and by month six have made the first depth hire, set up board reporting, scaled one program and cut another, and show marketing-sourced pipeline moving toward target. Agree on that definition of success before day one.

Most marketing leader hires that fail don’t fail on talent. They fail because nobody agreed in writing what “working” would look like, so success gets redefined after the fact by whoever is unhappy. I wrote about what that costs in The Real Cost of a Marketing Leader Mis-Hire. Research on venture-backed companies has found the average first marketing hire lasts less than twelve months.

This post covers what to expect from a new full-time marketing leader in their first six months, how to hand off cleanly if a fractional leader came first, and when converting a fractional leader into the full-time role makes sense for both sides. It builds on Fractional CMO or Full-Time Hire? and How to Scope a Fractional CMO Engagement.

Before day one: define success in writing

Agree on three things before the offer goes out, and make sure the CEO and the board give the same answer:

• One problem statement. The sentence that explains why this role exists now.
• Three to five goals with a target for month six. Tied to the problem, each with a baseline and an owner.
• A six-month check-in. A set date to compare results to the plan, so the review isn’t triggered by a bad week.

The role itself needs the same care. The marketing leader’s title and scope should sit at parity with the other leaders around the table, and the role should report to the CEO as a peer to sales. A leader without an equal seat can’t push back on targets, budget, or ICP, and the goals above stop being theirs to own. How to Hire for GTM builds a scoped role around the lead discipline your gaps call for.

The first 30 days

A new leader’s first month looks different depending on what they walk into. If there’s no diagnosis, they build one: pipeline sources, spend, positioning, the tech stack, the team, and conversations with customers, lost deals, and sales. If they inherit a diagnosis, they test it against what they hear. They shouldn’t re-audit from zero, and they shouldn’t accept it uncritically either.

By day 90

They own the plan. They’ve changed what they disagree with and explained why, in writing. They’ve agreed a marketing pipeline target with the sales leader as a peer, not received one. The CEO should be able to describe the plan in the leader’s words.

By month six

• The first depth hire is made or approved, filling the gap the leader isn’t deep in.
• A board reporting cadence is running. The Board Slide Planner is a good structure for it.
• The CEO spends noticeably less time on marketing.
• At least one program has been scaled because of its return, and one has been cut.
• Sales pulls marketing into deals instead of working around it.
• Marketing-sourced pipeline is trending toward the target agreed at day 90.

If they inherited a diagnosis and working foundations, hold them to a faster clock than a leader starting cold.

Warning signs at month six

• They’re rebuilding the playbook from their last company instead of the one in front of them.
• They asked for budget before they had a plan.
• They haven’t built a working peer relationship with sales.
• They still haven’t hired anyone.

One warning sign is a conversation. Several together usually mean the role and the person don’t match, and that is cheaper to name at month six than at month eighteen.

If a fractional leader came first, hand off cleanly

When a fractional engagement comes before a full-time hire, the new leader should inherit something better than a blank page. Before the engagement ends, they should have:

• A written diagnosis of the marketing function and the data behind it.
• A working budget that shows what is committed and what is still open. Event contracts in particular get signed months ahead, so the new leader needs to know which ones are already locked.
• Reporting and attribution they can rely on from the first week.
• A 90-day plan they can adopt, change, or throw out, with the reasoning written down.
• Two to four weeks of overlap with the fractional leader, so context moves in person rather than in a slide deck.

Then the fractional leader should step out. Staying on past the handoff confuses the team about who is in charge.

When converting a fractional leader makes sense for both sides

Sometimes the right full-time hire is the person already in the seat. Conversion skips the search fee, which typically runs 25 to 35% of first-year compensation. At the $324,500 midpoint of the Hiring Index CMO band for Seed through Series D cybersecurity companies, that is roughly $81,000 to $114,000 on base alone, and the onboarding has already happened. It works when it makes sense for both sides, not just the convenient one.

It makes sense for the company when:

• The full-time role matches the fractional leader’s lead discipline. If the gap map says you need a demand-led leader and your fractional CMO is a brand builder, the fit is wrong no matter how well the engagement went.
• The work has outgrown the fractional scope. The team needs daily management, or the motion needs someone in market every day for the long term.
• The goals agreed at kickoff were met, so you’ve seen the person deliver against your own baselines, not just interview well.
• You’d still choose them after seeing a shortlist. Benchmark them against the market, even informally, so the decision isn’t only about saving time.

It makes sense for the leader when:

• They want the seat. Some fractional leaders run a portfolio on purpose and are better at it than they would be in one company.
• The offer reflects the full-time scope: base set against the band, a real equity grant, and a title at parity with the rest of the leadership team.
• They believe in the company after seeing it from the inside, which is more than most candidates ever get to know.
• Leaving other clients is a choice they’re making, not a cost they’re absorbing to keep the engagement.

How to handle it well. Raise conversion as a possibility at kickoff so nobody is surprised, and set a decision point around month four or five. Put the offer through the same scrutiny as an outside candidate’s. Discuss whether fractional months count toward the vesting cliff; it’s a fair question, and settling it up front avoids resentment later. If either side hesitates at the decision point, run the search and let the fractional leader help hire the right person. That outcome is a success too.

Where to start

Define success before you define the job description. How to Hire for GTM breaks the marketing leader role into six lead disciplines and builds a scoped role around the one your gaps call for, including the depth hires underneath.
