One in five new creator marketing job postings now name Reddit or Substack by title, not as an afterthought buried in a “nice to have” bullet. That is not a coincidence. It is a hiring strategy. Brands that spent a decade building TikTok and Instagram specialists are now rewriting job descriptions around a different skill: platform agnostic creator fluency, with Reddit and Substack sitting at the center of the shift.
The Job Descriptions Already Gave It Away
Look closely at what agencies and in-house teams are actually asking for. A senior social strategist role at Daniel J Edelman Holdings, posted for a Los Angeles-based team, asks candidates to specialize in what’s next, from creators and podcasts to new platforms like Threads, Reddit, Discord, and Substack. That is not a TikTok job with a Reddit line tacked on. It is a mandate to understand distinct community cultures, each with its own norms, each capable of torching a campaign if handled like paid social.
Identity verification company Socure posted a similar brief, telling candidates to expand the brand’s presence beyond LinkedIn by cultivating audiences on channels such as Substack, Reddit, Product Hunt, and other niche or emerging communities. These are B2B and fintech-adjacent companies, not DTC beauty brands chasing Gen Z virality. That matters. When compliance-heavy, risk-averse sectors start writing Reddit and Substack into job descriptions, it signals the shift has moved past early adopters.
Why Platform Specialists Are Losing Ground
For years, the dominant hiring model was the specialist: a TikTok manager, an Instagram lead, a YouTube partnerships person. That made sense when the big four platforms absorbed most attention and most budget. It makes much less sense now. Reddit and Substack do not reward the same skills as short-form video platforms, and a specialist trained only on algorithmic feeds will stumble badly on both.
Reddit’s own advertiser data shows campaigns that ignore subreddit culture underperform badly, a constraint that Huntress and other case-study brands addressed by matching creative to community norms rather than repurposing existing paid social assets.
Reddit is blunt, skeptical, and allergic to anything that smells like a repurposed TikTok script. Substack is slow, text-heavy, and built on a subscriber’s deliberate choice to pay for someone’s judgment. A brand manager fluent in hook-driven short video has to unlearn instincts before they can work either channel well. That retraining cost is exactly why companies are hiring fresh rather than retrofitting, and why creator fluency across platforms has started showing up as a baseline expectation rather than a bonus skill.
Reddit’s Numbers Finally Caught Up to the Hype
Marketers spent years treating Reddit as a cult channel for niche B2B plays. That framing is outdated. Reddit’s advertising revenue increased by 75% year-over-year, with the company’s latest quarterly report showing the platform added 5 million daily active users in a single quarter while pushing deeper into AI-powered targeting. The company now counts 121.4 million daily active users, up from 116 million last quarter and up 19% year-over-year, with 471 million weekly active users on the platform.
Budget follows attention, and attention is now measurable. According to agency sources speaking to Digiday, some advertisers now allocate between 5% and 20% of paid media budgets to the platform. One paid social director put it plainly: this year brought more clients either who have just launched on Reddit, or are getting ready to launch, than ever before, according to reporting from The Keyword. That is not a test budget anymore. That is a line item with a growth trajectory.
Here is the catch: media spend scaling faster than internal fluency creates risk. You cannot buy your way around a subreddit’s distrust of branded content. A junior buyer dropping promoted posts into the wrong community gets ratio’d, screenshotted, and occasionally turned into the next cautionary case study on marketing Twitter. That is the exact gap platform agnostic hiring is meant to close, and it dovetails with the broader pattern covered in niche marketing on Reddit and Discord as brands flee degraded public feeds for smaller, higher-trust rooms.
Substack Stopped Being a Newsletter and Became a Media Business
Substack’s pitch to brands has shifted dramatically in the past year, and the numbers explain why. The platform’s native sponsorships program now counts flagship partners who are collectively investing millions of dollars into creators on Substack, including Yahoo Scout, Whatnot, Granola, Balenciaga, T-Mobile, Polymarket, and Uber. That is not pocket change from brands testing a side channel. That is enterprise marketing budget following creator trust at scale.
The scale underneath those deals is what makes the opportunity real. Substack reports that more than 100,000 publishers now make money on the platform through subscriptions, and the top 10 collectively make more than $100 million a year. Dan Robbins, Substack’s head of brand sponsorships, told Beet.TV that brands come to the platform because they want somewhere to go deep, tell their story, and deliver trust, which he described as different from showing up in a feed or doing a paid boost, according to the full Beet.TV interview.
Substack’s move into advertising was gradual and deliberate by design. The company’s cofounder said the earlier beta program was built to help creators earn incremental revenue without disrupting subscriptions, a framing confirmed in Adweek’s coverage of the pilot. That caution matters for brand teams. Substack sponsorships are not programmatic buys you can automate through a DSP. They are negotiated, editorially-controlled placements where the creator keeps final say, which means the skill set required looks far more like media relations than performance marketing. This is the same dynamic Influencers Time flagged when covering how Substack grew into a full media stack that most brand budgets still underprice.
The Hiring Logic: One Generalist Beats Three Specialists
Here is the budget math driving this. Hiring three platform specialists (one for Reddit, one for Substack, one for whatever emerges next) is expensive, slow to onboard, and creates coordination overhead nobody wants to manage. Hiring one creator marketer who can flex across community-based and subscription-based channels is cheaper and faster, provided that person actually understands the cultural logic of each platform rather than treating them as interchangeable distribution pipes.
The brands moving fastest on Reddit and Substack are not the ones with the biggest media budgets. They are the ones who stopped hiring for platforms and started hiring for judgment.
This mirrors a pattern already reshaping org charts elsewhere in marketing. As agency hiring freezes push brands toward in-house creator teams, the economic pressure to consolidate skill sets into fewer, more versatile hires has only intensified. It also explains why creator marketing pay is bifurcating so sharply: generalists with proven platform agnostic judgment command premium salaries, while narrow platform-specific coordinators get squeezed.
There is a real-world case study baked into Substack’s own brand roster. Footwear brand Rothy’s built creator relationships organically, with its VP of brand and communications noting the platform stands out because algorithm-driven feeds often surface the same content and make trusted tastemakers more valuable. Rothy’s worked with writer Emily Sundberg after she posted about wearing the brand’s flats on her wedding day, later sponsoring a pizza party for her readers, and expanded that into a broader anniversary campaign partnering with five Substack creators including Veurink, Hunter Harris, Rose Anderson, Noora Raj Brown and Plum Sykes. That kind of relationship-first sequencing cannot be executed by someone trained purely on media buying dashboards. It requires a marketer who reads newsletters, understands subscriber psychology, and knows when a sponsorship would feel like an intrusion rather than a value-add.
What to Actually Look For When Hiring
If you are rewriting your own job descriptions, resist the urge to just add “Reddit and Substack experience” as a bullet point and call it done. The candidates worth hiring usually show a few consistent traits:
- They can explain why a promotional post gets downvoted on Reddit even when the product is genuinely good, and can point to subreddit-specific norms rather than generic “be authentic” advice.
- They understand Substack’s subscription economics well enough to know why a sponsored post performs differently than a sponsored Instagram Story, including the editorial control creators retain over sponsorship formats.
- They treat community platforms as long-term relationship building, not campaign sprints. Reddit practitioners widely note that credible presence takes real sustained participation, not a single paid flight.
- They can speak fluently about measurement tradeoffs, since neither platform offers the clean last-click attribution marketers got used to on paid social.
That last point connects to a broader measurement reckoning happening across the industry. Brands chasing proof over vanity engagement are running into the same wall on Reddit and Substack that they hit everywhere else, a tension explored in how sentiment and hard proof split ROI measurement. Substack’s own push toward independent Kantar-backed brand measurement for sponsorship campaigns is a direct response to that pressure, and it signals the company expects advertisers to demand accountability that matches spend.
FAQs
What does “platform agnostic” mean in a creator marketing job posting?
It means the role is not scoped to a single network like TikTok or Instagram. Instead, the candidate is expected to move fluently across multiple creator ecosystems, including community-driven platforms like Reddit and subscription-based platforms like Substack, applying the right cultural approach to each rather than copying one playbook everywhere.
Why are brands suddenly interested in Substack for marketing?
Substack has formalized a native sponsorship program with flagship partners investing millions into creator campaigns, and the platform now supports over 100,000 paid publishers with the top earners collectively making more than $100 million a year. That scale, paired with high reader trust, makes it attractive for brands seeking depth over reach.
Is Reddit advertising actually worth the budget shift?
Reddit’s ad revenue grew 75% year-over-year with daily active users climbing to 121.4 million, and agencies report some clients now allocating between 5% and 20% of paid media budgets to the platform. Results depend heavily on matching creative to subreddit culture, which is why cultural fluency matters as much as budget size.
Should brands hire a dedicated Reddit specialist or a generalist creator marketer?
Most brands are moving toward generalist hires with demonstrated fluency across multiple platforms rather than narrow specialists, since job postings increasingly bundle Reddit, Substack, Discord, and Threads into a single role. This consolidates budget and reduces coordination overhead compared to maintaining separate platform teams.
What skills should a platform agnostic creator marketer have beyond platform knowledge?
Beyond understanding individual platform norms, strong candidates bring negotiation skills for editorially-controlled placements, comfort with measurement models that go beyond last-click attribution, and patience for relationship-based community building rather than campaign-sprint thinking.
The brands winning on Reddit and Substack right now are not the ones with the biggest media budgets. They are the ones who rewrote the job description first. Start there: audit your next creator marketing hire for platform agnostic judgment, not platform-specific tenure.
