How Adam Robinson Scaled LinkedIn Ads From $0 to $50k/Month

TLDR: From zero ad spend to $50K/month using existing LinkedIn content

Adam Robinson, founder and CEO of retention.com and RB2B, had no paid media program before working with Understory. Within months, he scaled LinkedIn ad spend to $40–50K/month using a simple "double it if it's working" approach.

Listen to this episode to learn how we built a Thought Leadership Ads program from scratch using Adam's existing content, how a lightweight audience-testing framework turned small budgets into scalable spend, and why Adam believes product-market fit and a $15–20K ACV threshold are prerequisites before investing in paid media.

Key insights

Starting from zero is a valid paid media strategy, if you scale spend to match what's already working.

RB2B had organic traction on LinkedIn before running a single paid dollar. Rather than guessing where to start, the program was built around amplifying what was already resonating. "There wasn't one. There's no other way to describe it than that. We weren't doing ads," Adam explains. The bet was simple: if LinkedIn organic is working, test whether paid spend accelerates it. For SaaS growth leaders sitting on strong organic channels, that question is worth asking before committing to creative from scratch or building a new channel entirely.

Thought Leadership Ads work because the content has already earned credibility before the spend kicks in.

As we discuss in the episode, the first step in building Adam's paid program was reviewing his best 25 organic LinkedIn posts. This was the content that had already proven engagement. We then built the paid strategy around that existing content using LinkedIn's Thought Leadership Ads format. The result: ads that didn't read or feel like ads. They carried Adam's voice and the credibility of posts that had already resonated. For founder-led SaaS brands, this approach removes most of the creative guesswork and keeps the content authentic to the person behind it.

Small-budget audience testing before scaling is what separates efficient paid programs from expensive guesses.

We came back with multiple audience segments to test before committing meaningful spend. "You guys came back with, I think, either three or nine suggested audiences for us to go after," Adam recalls. Small amounts went out across those segments to see which posts generated engagement from which audiences. Only then did the spend grow behind the winners. As we discuss in the episode, this testing-first methodology is how we avoid over-investing in untested assumptions, and it's the foundation of how we approach LinkedIn paid media for SaaS clients more broadly.

A paid media partner should reduce coordination overhead, not add to it.

After initial setup, Adam's ongoing commitment was a single weekly update call. "The only thing it required from us was just a weekly update call to just make sure we understood what was going on to report back to our team. It was a beautiful process," he shares. We handled strategy, implementation, and execution. Adam handled content. That division of labor matters: SaaS growth leaders are already stretched, and a partner that requires constant input creates more drag than it removes. The weekly call was a checkpoint, not a working session.

The content handoff model is a repeatable template for any founder-led SaaS brand running paid social.

The workflow was deliberately simple: Adam creates LinkedIn content as part of his existing organic strategy, then hands it off. We bring the paid strategy, audience targeting, and budget allocation. "It was you creating content and then you just pass it off to us and we come with the strategy, the implementation and the execution," Alex summarizes, and Adam confirms. For SaaS founders already producing high-engagement posts, the infrastructure to turn that into a paid media channel is simpler than it looks. The key is a partner who handles the operational layer without disrupting the content creation habit.

Cross-channel retargeting turns LinkedIn engagement into a multi-platform presence without separate creative strategies.

One result Adam flagged that goes beyond standard LinkedIn metrics: cross-platform visibility. "Anecdotally, people tell me all the time. They see my stuff, my selfie video ads on Instagram," he notes. As we discuss in the episode, we built on-channel LinkedIn retargeting and extended it to other platforms. B2B buyers don't live exclusively on LinkedIn, they scroll Instagram and browse other channels throughout the day. Retargeting keeps the brand visible across those touchpoints using engagement data from one channel to inform reach on others.

Affiliate link tracking closes the attribution gap between LinkedIn engagement and actual signups.

Engagement metrics, including likes, comments, and views, are useful but don't connect ad spend to business results. Adam's team solved this by embedding affiliate links in sponsored posts. "If we put an affiliate link in there, we can actually see cost per signup," he explains. This simple tactic bridges top-of-funnel engagement with bottom-of-funnel conversion data. For SaaS growth teams running Thought Leadership Ads, trackable links tied to product signups or demo requests turn a brand awareness play into a measurable acquisition channel, which makes the case for continued investment far easier to justify.

Ads work best as an accelerant, not a foundation. PMF, message-market fit, and ACV threshold all come first.

Adam is direct about who isn't ready for paid media. "If you are pre the ability to systematically find and close customers, then you are not ready for ads yet. You should do outreach with a cheaper channel, do your own email through Instantly or whatever else," he says. His three readiness criteria: decent product-market fit, strong message-market fit, and an ACV above $15–20K where paid unit economics hold. Below that threshold, outbound through GTM engineering is typically a better starting point. Once the foundation is solid, paid media can accelerate what's already working.
