"When to hire developer relations" usually gets answered with a headcount number or an ARR milestone. That's the wrong signal. The real one is simpler: someone on your team is already doing DevRel's job badly, part-time, and without anyone naming it, and you haven't noticed yet.
We work with early-stage B2B SaaS founders on GTM, and the pattern repeats. An engineer answers the same onboarding question in Slack or Discord every week. A founder rewrites docs at midnight before a launch. A "community" channel is really a support queue with better branding. Nobody calls it developer relations until it breaks, and by the time it breaks, the debt has already been compounding: docs are stale, trust is worn thin, and a competitor's community has become the default place developers go to get unstuck.
Founders who wait too long usually aren't missing the signal. They're missing a name for what it means.
The signal that looks like something else
The clearest sign you need developer relations isn't slowing growth, it's rising internal cost: your best engineers spending non-engineering hours answering the same onboarding questions, week after week, in Slack, Discord, or support.
This gets misread constantly. It looks like a support problem, so it gets routed to whoever's free. It looks like a docs problem, so it gets queued behind the roadmap. It never gets treated as its own function, because nobody's job depends on treating it that way.
By the time most startups hire their first developer relations person, someone was already doing the work, just reactively and without structure. The hire doesn't create the function. It finally gives it an owner.
The moment worth watching for isn't a stage or a revenue number. It's when the engineer doing this work stops being an amplifier for the product and starts being a repeater of the same five answers.
What the wait actually costs
The cost of waiting isn't a missed hire, it's compounding onboarding friction. Every week without a dedicated owner, time-to-first-success creeps up, and each new cohort of developers gets a slightly worse version of the experience than the last one did.
- Docs debt. Nobody owns keeping examples current against the actual product, so support tickets quietly become the real changelog of what's broken.
- Community erosion. Slow answers push developers toward whichever competitor's Discord responds faster. Once a developer picks a place to get unstuck, they rarely go looking for a second one.
- Founder time. Every gap gets patched by whoever's most available, usually the founder, which means the highest-leverage person in the company is doing the lowest-leverage version of this job.
None of these show up on a dashboard labeled "DevRel." They show up as slower activation, noisier support, and a founder who can't explain where the week went.
The deal that made the cost visible
One founder we worked with sat in a technical evaluation call eighteen months after an engineer first flagged the same onboarding question for the tenth time that quarter. The prospect's evaluator opened with a complaint, not a question: their Discord had taken two days to answer a basic auth issue during the trial. Was that normal?
It wasn't the product that nearly cost the deal. It was the absence of anyone whose job was to make sure that never happened.
The deal closed, barely, after the founder personally answered questions on that eval thread for two weeks straight. That's founder-led developer relations working as an emergency patch instead of a system, and it's ten-plus hours a week that should have gone into the next ten deals in the pipeline, not one rescue mission.
The actual timing signal
Hire developer relations once founder-led or engineer-led DevRel is clearly working and has become the bottleneck, not before you have anything worth advocating for.
PostHog has written about building its developer relations motion this way: founder-led and content-first until the approach was proven, then hiring to scale what was already working, not to invent it from nothing.
Waiting isn't free, but hiring too early isn't a shortcut either. The debt only starts compounding once the signal is ignored, not before the signal exists.
What to do first
Spend the next 30 days tracking one number: how many hours a week your best engineer spends on non-engineering developer relations work, meaning Slack or Discord answers, doc fixes, and onboarding calls.
If that number is climbing and it's already past three or four hours a week, the wait isn't buying you optionality anymore. It's just deferring a hire you've already made informally, minus the job title and minus anyone accountable for doing it well.
Frequently asked questions
When should a startup hire its first developer relations person?
Once founder-led or engineer-led DevRel is clearly working and has become the bottleneck, meaning inbound questions and content demand outpace what one person can sustain alongside their actual job. Hiring earlier means paying someone to invent a motion from scratch.
What's the difference between developer relations and technical support?
Support reacts to individual problems as they happen. Developer relations builds the docs, content, and community systems that prevent most of those problems from reaching support in the first place.
Can a generalist replace years of ad-hoc, founder-led developer relations?
Usually, yes, if they can code, write, and talk to developers directly. The job isn't inventing the motion, it's systematizing what the founder already proved works.
How do you measure whether developer relations is working before you hire anyone?
Track time-to-first-success, the trend in repeated onboarding questions, and how much non-engineering time your best engineers spend answering them. Rising numbers on any of those are the real signal, not follower counts or conference invites.
Is developer relations worth it for a startup with a small developer audience?
Not as a headcount decision this early. It's worth it as a set of habits: clear docs, honest technical content, and fast answers, done founder-led, long before it's worth a dedicated hire.
The 18 months we waited didn't feel like a decision at the time. It felt like every other week where something more urgent came up. That's exactly how the debt gets missed: not in one bad call, but in a hundred reasonable ones.
