How we vet every listicle
Every agency featured on Web Tonic passes our 84-point editorial review before a single listicle goes live. This is how we vet each pick:
Verified client outcomes: We require real case studies with measurable KPIs — revenue, ROAS, CPA, retention — tied to the exact category being ranked. No cherry-picked wins, no unverifiable numbers.
Independent reputation: We cross-check Clutch, Google, G2, and Trustpilot ratings, and screen for review-bombing or suspicious patterns. Only operators with a consistent, verifiable track record make the cut.
Beyond that, every listing goes through a quarterly re-audit. We check 84 criteria across 6 pillars to make sure it still holds up — here are some of the checks we run:
A fractional head of growth is a senior operator rented by the month rather than hired: the person who owns the growth number, decides which channels get funded next quarter, sets the reporting everyone argues over, and directs the agencies, freelancers or in-house juniors already doing the work.
Calling yourself a growth partner counted for nothing here. We wanted the engagement behind the phrase: named growth leadership, strategy or fractional-executive work sold as an ongoing seat, evidence on the firm's own pages, and its own logo. Nine external firms in Miami cleared that bar, eight sell growth or strategy as a core discipline, and seven back the city claim with a full street address rather than a bare city line.
What does a Miami fractional head of growth actually do?
Senior growth ownership on a part-time retainer: the roadmap, the budget calls, the reporting and the people doing the work. Nine external firms serving Miami cleared our evidence read, nine are headquartered in the city, and one name a client you can verify yourself.

Frequently Asked Questions
What does a fractional head of growth in Miami actually own?
The number, not the tasks. They decide where next quarter's budget goes, kill the channels that cannot be made to work, set the reporting the whole team argues from, and hold the agencies and juniors already in place to a plan. If the engagement only produces advice and no decisions carry their name, you bought a consultant with a better title, and the growth number keeps drifting back to whoever it belonged to before.
How many days a month is enough?
Two days rarely moves anything once meetings are subtracted, and five days starts to look like a salary. Most workable retainers land between six and ten days a month, weighted heavily toward the first quarter while the operator rebuilds reporting and clears the backlog. Agree the day count, who they may direct, and what they can approve without you, because an operator without authority is an expensive observer.
Which firms here name clients I can check?
One of the nine do. Alfatek Digital points at Therapy Works and Horizon X. The others credit nobody on the pages we read, which is common when the work sits inside a client's own leadership team, but it moves the proof onto references. Ask for two growth seats held in your category, what the operator changed in the first ninety days, and what happened after they stepped out.
Why do proposals for the same brief differ so much?
Because the seat is defined loosely and everything hides in the detail. Fix the monthly days, whether the operator manages your existing agencies, whether execution capacity comes with them or is billed separately, how reporting gets rebuilt, and the notice period on both sides. Once those are written down, the spread between quotes collapses into something you can genuinely compare.
Should the same firm also run the execution?
It cuts both ways, so decide before briefing. An advice-only operator defends no budget of its own; a firm that also executes knows what its own roadmap costs to deliver. Nine of the nine external firms here are headquartered in Miami, and none of them publishes a rate. Either way, insist on a written handover plan from day one, because a growth seat nobody can vacate cleanly turns into a dependency.
Choosing a Fractional Head of Growth in Miami
Nine of the nine external firms here are headquartered in Miami, so proximity alone will not shorten your shortlist. The real split is between firms that take decisions and firms that supply opinions.
One name a client you can verify, and every fee on this page is quoted against scope rather than published. Settle days per month, authority and reporting before the proposals arrive.
A growth seat is worth what it leaves behind. Ask what the ninety-day review measures, who inherits the roadmap, and which single number the whole retainer exists to move.
Whoever wins the brief, keep the leadership and the work it directs under one accountability line, because a strategy nobody is paid to deliver quietly becomes somebody else's problem. If you would rather the growth seat, the leadership retainer and the execution beneath it answer to one team, read our latest analysis or see how we work in Miami.
