Winning the Brand War: How Legacy Brands Become the Category Leader

I was talking to a new Chief Executive Officer (CEO) last week whose biggest concern was this: over 20 years in market, and their company still wasn’t seen as the leader in their category. They should have been winning more deals just based on tenure alone. They weren’t.

That conversation is where this blog starts, because it turns out that same concern shows up almost everywhere when you ask what’s actually keeping marketing leaders up at night.

The Most Researched Question: How Do We Prove Marketing ROI?

Funny enough, as I began researching for this piece, I asked the large language models (LLMs) what the most searched question was among marketing leaders right now. Here’s what came back, and a couple more worth noting.

The top answer, across nearly every 2026 survey, was some version of “how do we prove marketing return on investment (ROI)?” HubSpot’s 2026 State of Marketing Report puts it at 33 percent of marketing leaders globally, rising to 40.8 percent among U.S. leaders specifically. Gartner’s data backs this up, showing revenue growth as the top chief marketing officer (CMO) priority heading into 2026, proving that growth actually ties back to marketing spend as the most urgent open question leaders have. The reason it’s so hard right now isn’t laziness or bad tools. Customer journeys have gotten longer and messier, spread across more channels than attribution models were ever built to handle.

A couple more worth noting. Artificial Intelligence (AI) implementation without losing brand control comes in close behind, with 68 percent of CMOs in the Serviceplan, St. Gallen, and Heidrick & Struggles CMO Barometer calling it the defining topic of the year, and 37 percent naming “losing brand control in the rush to keep up” as their top AI concern. Customer experience, or CX, jumped hard too. Forrester found CX went from not even cracking the top five priorities to the number one B2B-to-consumer (B2C) focus in 2026. Burnout showed up more than expected as well, with 25.9 percent of leaders managing teams naming it their top personal challenge.

What’s interesting is that these aren’t four separate problems. ROI pressure, AI anxiety, CX demands, and burnout all trace back to the same root: teams being asked to move faster than their systems, tools, or people can actually support. Bloomberg Media and Lippincott’s CMO Outlook research gets at this directly. CMOs say long-term growth is what they care about, but day-to-day they’re pulled toward proving short-term wins, and that tension is where most of the strain lives.

How Established Brands Win the Brand War and Become the Category Leader

This is where that CEO conversation connects directly to the ROI question, because winning the brand war and proving marketing ROI are the same fight, just measured differently.

Being in market a long time doesn’t automatically buy you category leadership anymore. Wharton’s research on legacy brand erosion found that companies losing ground usually don’t notice it happening. They keep assuming customers will stay loyal out of habit while competitors quietly meet people where they actually are now. ET BrandEquity’s reporting on legacy decline makes the sharper point: trust without action becomes nostalgia, not sales, and a familiar name isn’t a strategy on its own. That’s the trap a lot of tenured brands fall into. They think longevity equals authority, when the market stopped rewarding longevity by itself years ago.

I’ve walked brands through this exact shift before, moving from nonexistent, or worse, being seen as the old brand or the cutesy brand, into being recognized as a real category leader. And I’ve done it in months, not years. Here’s how.

Stop Showing Up Like the Old Version of Yourself

If you’re a growing brand trying to hit a billion-dollar valuation, you cannot show up at an event with a spinning wheel giving away fifty-cent keychains. That’s not a small aesthetic choice; it’s a signal. Research on brand relevance found that legacy assets people used to see as heritage, like a familiar giveaway table, have started reading as baggage instead, a sign the brand hasn’t moved. Premium and limited items, coffee, a happy hour- these read completely differently. People don’t want stuff anymore; they want an experience. The questions your team asks prospects at that happy hour should shift too: less pitch, more curiosity about their actual problem.

Thought Leadership Is the Fastest Lever Available

This is the part that surprised me most in the data. Edelman and LinkedIn’s business-to-business (B2B) research found 75 percent of decision makers say a piece of thought leadership led them to research a company they weren’t previously considering, and 60 percent said strong thought leadership made them willing to pay a premium to work with that company. That’s a direct line from brand perception to revenue, the exact connection CMOs are struggling to prove when asked about ROI. Seventy-three percent of B2B buyers also say thought leadership content is more trustworthy than marketing materials or product sheets, meaning the content itself has to sound like real expertise, not a sales deck broken into paragraphs.

Speed Is the Real Advantage Challengers Have, and It’s Copyable

Northera’s breakdown of why incumbents lose to smaller competitors nails the mechanism. It’s not that challenger brands have better talent; it’s that they ship brand and campaign changes every six weeks while incumbents ship once a year. The fix isn’t more budget; it’s cutting the approval chain from weeks to days and giving teams a working identity kit instead of a ninety-page PDF nobody opens. A twenty-year-old brand can move like a five-year-old one internally, even if the market still sees the old version externally for a while longer.

Audit What’s Pulling You Forward Versus Dragging You Back

Research on legacy brand recovery recommends being ruthless here. Cut the positioning and products that aren’t future-proofed, then identify the one emotional core that makes the brand irreplaceable and rebuild every touchpoint around reinforcing it. This internal clarity work has to happen before any external campaign, because customers can tell when a brand’s messaging and its actual activations don’t match.

The Through Line

Showing up as an elite brand isn’t about spending more; it’s about spending differently and moving faster than your own history says you’re allowed to. That’s the same answer as the ROI question. Prospects don’t experience your ROI; they experience your brand, your speed, and whether the room you invited them into felt premium or felt like a leftover from 2015.

If You’re Ready to Move Forward with a Rebrand, What Should You Expect?

Here’s a quick checklist and what to actually expect when executing, so you’re not draining digital spend while you’re trying to drive down customer acquisition cost (CAC) and increase return on ad spend (ROAS).

Before You Touch a Single Ad Account

Name the root cause, not the symptom. A rebranding checklist puts this first for a reason: “our positioning no longer reflects the audience we serve” is a root cause; a new logo idea is not
Set a CAC baseline before you change anything. Research is blunt about this: without three months of pre-rebrand CAC, conversion, and marketing spend data, you cannot separate rebrand effects from normal market noise
Build a Brand Equity Preservation Map. Plot every existing brand element on a grid of recognizability versus positive customer association, so you know what to protect and what to retire before creative work starts
Budget realistically, and build in a buffer. Data shows rebrands run from around $50,000 for small businesses to $500,000 plus for mid-sized companies, and recommends a 20 percent contingency built in before executive sign-off, not after

What to Expect During Execution

This is the part most leaders get blindsided by if nobody tells them ahead of time.

CAC almost always goes up before it goes down. Data shows a 15 to 30 percent increase in acquisition costs immediately after launch is normal, driven by market confusion and the extra spend needed to rebuild recognition, with costs typically stabilizing between months three and six . This lines up with research showing a well executed rebrand often takes 6 to 18 months to fully recoup its upfront investment, but recognizable, credible brands eventually see acquisition costs drop 15 to 30 percent below where they started, not just back to baseline . The leaders who panic and pull budget the moment CAC ticks up in month one are the ones who never get to see the recovery curve play out.

How to Execute Without Draining Digital Spend

Phase the rollout, don’t flip a switch. Recommendations call for introducing new brand elements progressively over several months while keeping familiar touchpoints intact, which softens the acquisition cost spike considerably
Prioritize by visibility and budget, not by what’s easiest. Tackle the website, social profiles, and primary sales materials first, since those touch the most prospects, and let lower visibility assets like signage or business cards transition over 3 to 6 months
Pilot before you scale spend. Test the new brand with a small customer segment or limited geographic market first, running A/B (split) tests on ads and landing pages comparing old versus new branding to catch confusion points before committing full budget
Keep your digital foundation stable. Preserve your URL (web address) where possible, set up proper redirects if you must change it, and keep social handles consistent, since losing SEO (search engine optimization) equity and follower continuity is one of the fastest ways to inflate CAC unnecessarily
Increase spend temporarily, but plan for it. Companies that don’t budget an extra 25 to 40 percent during the transition period tend to lose market share, because rebuilding awareness costs more than maintaining it

Train Internal Teams Before the Public Launch

Update sales scripts, pitch decks, and support documentation, and brief employees before customers see anything, since a sales team pitching the old positioning while ads run the new one is a silent CAC killer.

How to Know It’s Working

Set your KPI (key performance indicator) cadence at 30, 90, and then 6 to 12 months out. Track CAC quarterly using total sales and marketing spend divided by new customers, alongside organic traffic and word-of-mouth signals, since a dropping CAC paired with rising organic reach is the clearest proof the brand itself is doing the work instead of paid spend carrying it. A case study on the DSM Firmenich rebrand is a useful real-world example here: when budgets were cut in half mid-project, a prioritization framework and phased flight plan still delivered key milestones without breaking brand consistency, which is proof that phased execution isn’t just about avoiding waste; it’s what makes a rebrand survivable if conditions change.
