Marketing in professional services has moved decisively beyond awareness-building to become a measurable driver of revenue, according to Gabriela Henault, CMO at Third Bridge. With over 20 years of experience leading brand strategy and digital transformation, Henault said the era of marketing acting as a support function is over, replaced by a model that ties campaigns directly to sales outcomes and client retention.
"The old days of marketing acting like an internal events or design agency are completely over. You can't just make pretty collaterals, organize a couple of client dinners, and call it a day," she said.
Henault described how her team shifted from supplying materials to commercial teams to co-owning business impact alongside them. Instead of broadcasting generic corporate messages, they now focus on understanding client pain points and delivering targeted messages through precise channels. That change, she said, was about "ensuring (and proving) that our work is actually bringing in new business and helping retain the clients we already have."
The data and technology shift
Two decades in the field have shown Henault two major transformations: the decline of the faceless corporate voice and the rise of data-driven decision-making. Employee advocacy now carries more weight than institutional branding. "Our in-house specialists and front-line teams build trust online by sharing their own genuine insights to their networks," she said, noting that the corporate voice now takes a backseat.
On the operational side, tools like HubSpot, LinkedIn, Oktopost, and Gong have replaced guesswork with traceable metrics. Her team can track a client's journey from a social media click to a signed contract. When they relaunched Third Bridge's website and revamped its social and email strategies, organic traffic rose 34% and the programs generated hundreds of digital leads in a single quarter. "Once the commercial teams saw that marketing was actually feeding them live opportunities, the scepticism completely vanished."
Measuring impact in a relationship-driven business
Henault groups marketing's commercial contribution into three buckets. Pipeline influence: 45% of website traffic now comes via organic search, social media, and direct brand searches-signs that market reputation drives independent client interest. Lead generation: tracking which social and email leads convert into closed deals. And lead nurture: when a prospect arrives at a meeting already informed because of prior engagement, marketing has shortened the sales cycle.
"Ultimately, it's all about showing how marketing helps drive steady, long-term revenue growth," she said.
What makes thought leadership stand out
Generic corporate content floods the internet, Henault said. Truly influential work requires a distinct, high-value insight tailored to a specific audience. "It needs to have a clear point of view, take a stance, and address a concrete challenge or pain point that the reader is actively facing." She also emphasized the messenger: letting employees lead conversations with their own voices builds more trust than publishing anonymous reports from a corporate account.
AI's opportunity and the caution it demands
AI enables personalization at scale and automates repetitive operational tasks, freeing teams for strategic work. But Henault warned that the ease of generating large volumes of content creates a real risk. "Because AI makes it so easy to generate significant volumes of content, there's a massive temptation to just pump out generic articles, which can quickly erode client trust."
In professional services, where reputation and human expertise define the brand, generalized AI outputs dilute the precise relevance clients pay for. "If your entire digital presence becomes generalized and untailored, you lose the precise relevance that makes you valuable," she said. The right approach: use AI to streamline operations, but protect the sharp, customized messaging and human relationships at the core of the business.
Advice for aspiring leaders
Henault pointed to three priorities for those moving into executive roles. First, lean into resilience and continuous learning-the periods that stretched her most, including starting her own business, produced the most growth. Second, tie your work directly to commercial outcomes. "Real influence comes from proving you can move the needle. Figure out what drives revenue for your company and make sure you can back up your achievements with solid data."
Finally, she stressed the importance of relationships and mentorship. "Success is a team sport-your most important job is to ensure people want to help you do well. True leadership isn't about you; it's about your team." Building up the next generation of talent, she said, naturally positions someone for executive leadership.
Why this matters for executives and strategy leaders
Henault's experience at Third Bridge highlights a fundamental shift: marketing now carries a burden of proof tied to revenue, not just visibility. For executives overseeing brand and growth, the priority is twofold-embedding data and technology into marketing operations while preserving the human expertise that clients trust. Ignoring either side of that equation will leave a firm's brand weaker and its growth harder to sustain.
