Agency, fractional lead,
first hire, or pilot.
The four ways a seed developer-tool company gets growth work done, with published prices and the situation each one fits. Written by the person who sells the fourth option, so the disclosure is below the table.

The honest version
A seed developer-tool company with a working product, no growth lead, and under $10,000 a month for marketing has four realistic ways to get growth work done. Three of them are good buys in the right situation. The table shows what each costs in 2026 according to published sources, what you get, and when it beats the pilot.
Disclosure: this page is written by GTM Labs, which sells the Growth Pilot. The agency and fractional figures come from the three sources linked in the table; the first-hire row has no dollar figure because salary depends on your market. The links were checked in October 2026; the figures are as those pages state them. Hire decisions should also include reference calls.
Four options, one table
| Option | What you pay | Commitment | What you get | Fits better than the pilot when |
|---|---|---|---|---|
| Developer-marketing agency Source: MarketerHire, 7 July 2026 | $8,000 to $20,000 a month for one channel; project work $5,000 to $40,000 over 4 to 12 weeks | 3 to 6 month contracts | A team executing one channel at volume: content, events, or paid | You already know the channel that works and need more hands on it |
| Boutique GTM agency Source: Prospeo | $5,000 to $15,000 a month | 3 to 6 month minimums | Outbound and pipeline systems run for you | You sell to sales-led buyers and want outbound run, not learned |
| Fractional CMO or growth lead Source: SaaS Hero (a vendor) | $2,500 to $6,000 a month for 4 to 8 hours a week | Not stated in the source | Senior judgment and a plan; execution stays with your team | You have people to execute and need someone to direct them |
| First growth hire | Salary plus equity; no published figure, it depends on your market | Open-ended | One person who owns growth and stays | You have found the channel and can keep one person busy on it full time |
| Growth Pilot (GTM Labs) | $5,000 fixed, half at kickoff, half on the last day | Four weeks, then optional Continuation at $2,500 a month | Two experiments run with your real users and channels, a decision every Friday, a readout and handover on day 28 | That is the pilot. Below: when it is not the right buy. |
When the pilot is the wrong buy
An agency fits better when
the channel is already proven and the constraint is hands. A pilot runs two experiments to find out what works; an agency runs the thing that works at volume. Paying $8,000 a month to scale a channel you have not tested is the expensive order of operations.
A fractional lead fits better when
you have a marketer or two who can execute and nobody to direct them. Four to eight hours a week of senior judgment is the right shape for that team. A pilot assumes the founder is the executor for four weeks.
A first hire fits better when
the channel is found and the work is continuous: a launch every quarter, a community to tend, a content engine to run. The pilot's day-28 handover is written for that person, and the two cards are the first thing they inherit.
FAQ
Agency or pilot, for a seed developer-tool company?
Agency when you know the channel and want it run at volume; the published range for one channel is $8,000 to $20,000 a month on 3 to 6 month contracts. Pilot when you do not know the channel yet: $5,000 fixed for four weeks, two experiments with real users, a decision every Friday.
Fractional growth lead or pilot?
A fractional lead at $2,500 to $6,000 a month for 4 to 8 hours a week gives you direction; your team still has to execute. A pilot gives you two executed experiments and a readout. If you have no team to direct, the pilot is the one that produces evidence.
First hire or pilot?
Hire when the channel is found and the work is continuous. A hire is an open-ended commitment; a pilot is four weeks and ends on day 28 with a handover written for whoever you hire next. Many founders run the pilot first so the hire inherits two tested cards instead of a blank page.
What happens after the pilot?
You keep everything: the baseline, both cards, the Friday reviews, the readout. If something worked, Continuation runs it at $2,500 a month, month to month, with one new experiment a month. If you hire, the cards go to your hire. If nothing worked, you have spent four weeks and $5,000 to learn that.
Where do the figures on this page come from?
Three published sources, linked in the table: MarketerHire's developer-marketing agency guide dated 7 July 2026, SaaS Hero's fractional CMO cost page for 2026 (a vendor page, so a vendor's claim), and Prospeo's GTM agency listing. The first-hire row carries no figure because salary depends on your market. The links were checked in October 2026.
The Growth Pilot
Four weeks, two real growth experiments, a decision every Friday.
If you do not yet know which channel works, the pilot is the option that produces evidence. For developer-tool and AI-product founders who don't have a growth lead yet. $5,000 fixed, half at kickoff. How a pilot runs · What an experiment card looks like
