Once you decide content is worth taking seriously, the next question is who actually does it, and the options are not interchangeable. A full-time in-house writer, a fractional content operator, and an agency each solve a different version of the problem, cost very different amounts, and fail in different ways. Picking wrong is expensive: a full-time hire before you are ready burns salary, and a generalist agency produces content your buyers see straight through. The right choice depends mostly on your stage, your budget, and how much you already know about whether content works for you.
Underneath the format question is one requirement that does not change, which is technical fluency. Whoever writes for a devtools audience has to understand the product well enough to be credible to engineers, and that single trait matters more than whether they sit on your team or bill you monthly.
In-house
A full-time content hire makes sense once you have steady, high-volume content needs and want someone fully embedded in the company, living with the product and the team day to day. The upside is depth: an in-house person learns your product and your buyers intimately and is always available. The cost is a full salary plus the risk of hiring too early, before you know content justifies it, and the difficulty of finding one person who can do strategy, write well, and understand your technology.
For most early devtools startups, a full-time content hire is premature. You commit a significant salary to a bet you have not yet validated, and if the person is strong on writing but weak on the technical side, or vice versa, you are stuck. This is the same timing logic as hiring any first marketer: hire in earnest when you know the need is real, not to figure out whether it is.
Fractional
A fractional content operator gives you senior content leadership and execution without a full-time salary, which fits the stage most early devtools companies are actually in. You get someone experienced running the content, often with a track record across many similar companies, at a fraction of the cost and commitment of a hire. The tradeoff is that they are not exclusively yours and not sitting in every internal conversation.
This works well when you need the content done right by someone who has done it before, but do not yet have the volume or certainty to justify a full-time salary. It is the same reasoning I lay out in fractional vs full-time vs agency for marketing generally, and it applies to content specifically: fractional buys you seniority and flexibility at the stage where both matter most.
Agency
An agency fits when your strategy is set and you need to scale production, more content, more consistently, than one person can produce. The risk for devtools specifically is that most general content agencies lack the technical depth to write for engineers, so you get polished pieces in a house style that your buyers dismiss on sight. If you go this route, choose an agency that specializes in technical or developer content and can show work that holds up to a skeptical engineer, not a generalist shop applying a template to your product.
Agencies also tend to need direction. They execute a strategy well but rarely set a good one for a technical audience on their own, so an agency works best layered under someone, in-house or fractional, who owns the direction and quality bar.
What to screen for, whatever you choose
The one thing to screen for across all three is whether the person or team can produce content a skeptical engineer respects. That means technical fluency, the ability to understand your product and interview your engineers, which is the method behind getting content out of busy engineers, and writing that survives a technical read. Ask for samples and judge them the way your buyers would: is this specific, is it correct, does it sound like someone who gets it.
A brilliant generalist writer who cannot grasp the technical substance will produce content your audience ignores, no matter how polished. The rare, valuable trait is someone who can write genuinely well and understand your technology, and finding that is worth more than the in-house versus fractional versus agency decision itself. If you want senior content handled without a full-time hire while you figure out the rest, that is the work I do, and you can tell me where your content stands today.
