Most technical founders resource marketing in one of three ways: a fractional or embedded consultant, a first full-time hire, or an agency. The right choice depends on your stage and on what you are trying to prove. Before you have a repeatable go-to-market motion, a senior fractional operator gets you strategy and execution for $4,000 to $20,000 per month without a permanent commitment. Once the motion works and you can fund it, a full-time hire in the $180,000 to $275,000 base range owns the function and compounds. An agency is the right call at any stage for one well-defined channel you cannot staff yourself. Here is how to decide, and when each option is genuinely the best one.
What are the three ways to staff devtools marketing?
A fractional or embedded consultant is a senior marketer who works with you part time, usually one to three days a week, and does the work rather than just advising (Optionality Lab, 2026). This is now a large and growing market: the number of professionals working fractionally roughly doubled from 60,000 in 2022 to 120,000 in 2024, and over 40 percent of US small and mid-sized businesses are expected to use fractional leadership by the end of 2026 (sci-tech-today, 2026).
A first full-time hire is a permanent marketing leader who owns the entire function, builds the team, and carries the number. They cost the most up front and are the hardest to unwind, but they also compound the longest.
An agency is an outside team you retain for a specific scope, usually one channel like paid, content, SEO, or demand generation. You get depth in that lane and very little outside it.
These are not mutually exclusive. Plenty of Series A companies run a fractional lead who directs one agency and one junior hire. The question is which one to reach for first, and when.
How much does each option actually cost?
Cost is the dimension founders anchor on, so start there and then correct for what you actually get.
A fractional marketing lead in the US runs $4,000 to $20,000 per month, with most engagements landing in the $8,000 to $15,000 range for one to three days a week (Optionality Lab, 2026). You can typically cancel on 30 days’ notice, so the real commitment is small.
A full-time head of marketing at a B2B SaaS or AI startup earns $180,000 to $275,000 in base salary, scaling by stage from roughly $180,000 to $220,000 at seed up to $250,000 or more past Series C, before equity and benefits (WithAgility, 2026). Loaded cost is meaningfully higher than base, and the search itself takes months.
An agency retainer for B2B runs $2,500 to $15,000 per month for most engagements, with multi-channel demand generation around $5,000 to $10,000 and full go-to-market programs reaching $10,000 to $30,000 and up (New Perspective, 2026). The headline number can look like a fractional lead, but the seniority and scope differ, which is the part cost alone hides.
Fractional vs full-time vs agency: a side-by-side
| Dimension | Fractional / embedded consultant | First full-time hire | Agency |
|---|---|---|---|
| Typical cost | $4,000 to $20,000 per month; most land $8,000 to $15,000 | $180,000 to $275,000 base, plus equity and benefits | $2,500 to $30,000+ per month by scope |
| Seniority you get | Senior operator, hands on the work | Depends on budget; often mid-level at seed pay | Mixed: senior strategy, junior execution |
| Ramp time | 30 to 45 days to impact | 6 to 9 months to hire and ramp | 4 to 8 weeks, plus learning your product |
| Breadth vs depth | Broad strategy plus focused execution | Broad, owns the whole function over time | Deep in one channel, thin outside it |
| Commitment | 1 to 3 days a week, cancel in ~30 days | Full time, hard and slow to unwind | Retainer, usually a 3 to 6 month minimum |
| Best stage | Pre-seed through Series A, or a leadership gap | Series A/B once the motion is proven | Any stage, for a defined channel |
Ramp is the line founders underweight. Fractional operators tend to show real output in 30 to 45 days because they have run the play before, while a traditional executive hire takes 6 to 9 months to source and get productive (sci-tech-today, 2026). At pre-seed and seed, that gap is most of your runway.
When is a fractional or embedded consultant the right call?
Choose fractional when you have not yet proven a repeatable go-to-market motion and cannot justify a permanent senior salary. This is the default for most pre-seed through Series A devtools companies.
The advantage is seniority per dollar. For the price of a mid-level manager, you get an operator who has positioned a category, run launches, and knows which channels waste money for a devtool. They set direction and do the work, so you are not paying a strategist to hand a plan to no one.
Fractional also fits a specific gap: a leadership vacancy between full-time heads of marketing, or a founder who needs a senior partner to build the first system before hiring under it. Devtools GTM has its own rules, from developer-first content to GEO and community, and a specialist who lives in that world ramps faster than a generalist. That is the work I do at Rare Bird Lab, and you can see the shape of it in the case studies.
The limit is hours. A fractional lead cannot also be your full-time content writer, your events team, and your SDR. When execution volume outgrows one to three days a week, it is time to add capacity underneath them or move to full time.
When should you make your first full-time marketing hire?
Make the full-time hire once you have a repeatable motion worth compounding and the funding to support the role. In practice that is usually Series A or B, after a fractional lead or the founder has proven which channels work.
A full-time head of marketing is the right call when marketing needs to be owned every day: managing a growing team, sitting in the leadership room, carrying pipeline targets quarter over quarter. A part-time engagement was never built to carry that kind of daily ownership.
Two cautions. First, do not hire full time to figure out the strategy from scratch. Hiring a permanent leader into an unproven motion means paying a premium and waiting 6 to 9 months to learn what a fractional operator could have told you in six weeks. Second, watch the seniority trap: a seed-stage budget often buys a mid-level marketer with a senior title, who then needs the strategic direction you hired them to provide. Prove the motion first, then hire someone to scale it.
When does an agency make sense?
Bring in an agency when you have one well-defined channel that needs specialist depth and volume you cannot staff internally. This is true at any stage.
Agencies are strongest at exactly that: paid media, SEO, technical content production, design, or event execution, run by people who do only that all day. If you know you need 12 technical blog posts a month or a paid program managed daily, an agency delivers depth and throughput a single hire cannot match.
The weakness shows up when founders expect an agency to own strategy. Most agencies optimize the channel you bought, not your whole go-to-market, and they carry a roster of other clients. Devtools makes this sharper, because an agency without real developer-audience experience will produce generic content that engineers ignore. Agencies also need direction. They perform best pointed at a clear goal by someone in-house, whether a fractional lead or a full-time head, which is why the strongest setups pair an agency with an owner rather than using one as a substitute for leadership.
Which one, when: a recommendation by stage
Here is the practical version, by stage.
Pre-seed to seed, before product-market fit: start fractional or embedded. You need senior strategy and hands-on execution to find the motion, without a permanent salary while everything is still changing. Add a single specialist agency only if one channel is obviously your wedge.
Seed to Series A, motion emerging: keep a fractional lead as the owner and add capacity beneath them, a junior hire or a focused agency, once execution outgrows a few days a week. This is where fractional plus one agency, directed by that lead, tends to work best.
Series A to B, motion proven and funded: make your first full-time hire to own and scale the function. Keep agencies for specialist depth, now reporting into a leader who can hold them accountable.
Growth stage: build the in-house team and use agencies surgically for spikes and specialties.
If you are somewhere between these and not sure which applies to you, that is a 30-minute conversation, not a guess. Tell me your stage and what you are trying to prove, and I will tell you honestly which of the three I would reach for, even when the answer is not me.
