Buyers look up your founder before they look up your company.

So do candidates, and so do investors.

Executives now attribute around 44 percent of a company's market value to the strength of the CEO's reputation.

On LinkedIn, a founder's personal profile reaches roughly 10 times the audience of the company page posting the same thing.

And 82 percent of people say they trust a company more when its leaders show up publicly.

A silent founder carries a real growth cost.

The catch is that audiences can tell the difference between a founder speaking and a ghostwriter performing, so the voice has to be genuinely theirs.

Building it is simpler than a personal rebrand: two or three themes the founder is credible on, a sustainable cadence, and earned coverage to extend the reach.

We build founder-led storytelling for founders in tech, climate, and capital markets, and our own team publishes under their own names.

What holds most founders back from being visible: time, or knowing what to say?

Your best-performing Google page might be invisible to the AI your buyers now ask first.

The overlap between top Google links and the sources AI assistants cite has fallen from around 70 percent to below 20 percent.

Read that again with your own content in mind.

Around 35 percent of consumers now start product research with an AI tool, and they read a synthesised answer that names a short list of brands.

If you are absent from that answer, you were never in the running, and no traffic report will tell you why.

Winning here is a communications job first, a technical one second.

AI systems cite sources they judge credible, and third-party coverage carries more weight than a brand talking about itself.

We build content designed to be retrieved and cited by AI systems, across the full set of questions buyers actually ask.

Have you checked whether AI assistants mention your brand yet?

A fabricated video of your CEO can move your share price before you finish reading this sentence.

In January, the Bombay Stock Exchange had to warn investors about deepfake videos of its own chief executive pushing fake stock tips.

The face was real. The voice was real. The advice was invented.

The World Economic Forum now ranks misinformation among the most severe short-term global risks for the third year running.

Yet fewer than half of businesses hold a documented crisis communications plan, and almost none plan for a convincing fake of their own leadership.

Boards keep filing deepfakes under IT.

The first hour of a synthetic-media attack is a communications problem: who verifies the clip, which channel responds first, and which spokesperson goes on camera.

Those decisions have to be made before the crisis, not during it.

We help boards prepare for exactly this moment, so the real CEO is never far behind the fake one.

Has your board rehearsed what it would do in the first 60 minutes?

You rank first on Google. AI has never heard of you.

That's becoming one of the biggest marketing challenges of 2026.

Research shows that more than 73% of brands ranking on Google's first page receive zero mentions in AI-generated answers. As more buyers turn to AI assistants to research products and services, traditional SEO alone is no longer enough.

The organisations winning AI search are becoming the source of trusted information through original research, industry insights and authoritative content.

Our latest article explores why AI search visibility is now just as important as Google rankings, and what organisations can do to stay visible.

Last week I swapped the office for a boat in Cockburn Sound.

I spent two days with Chris de Cuyper and the Fremantle Seaweed team, visiting the operation behind the first investment made through Third Hemisphere's venture arm. Seeing the farm in person reinforced something we've believed since we first backed the business: the most compelling climate companies are usually built long before the rest of the market notices them.

Fremantle Seaweed isn't just developing a methane-reducing feed additive. It's solving one of agriculture's biggest commercial challenges by proving that asparagopsis can be cultivated at scale, reliably and cost-effectively in the ocean. That's the difficult part, and it's exactly why we invested.

The trip was also a reminder that venture investing isn't just about capital. It's about backing founders, understanding their business firsthand and helping them build the visibility, credibility and communications needed to scale.

I shared a few reflections from the visit, what I learned on the water, and why we're excited about where Fremantle Seaweed is heading next.

Most organisations don't discover the strength of their reputation during a crisis. They discover the reputation they have already built.

It's a subtle distinction, but an important one. By the time a difficult issue becomes public, customers, journalists, investors and employees have often spent months or years forming an opinion about the organisation involved. Every media interview, founder article, industry insight and piece of thought leadership contributes to that picture, making crisis communications about far more than responding well under pressure.

In our latest article, we explore why the strongest crisis communications strategies begin long before a crisis emerges, how content marketing and public relations have become fundamental to reputation management, and why building trust before you need it has never been more important.

How much of a crisis response do you think is shaped by the reputation that already exists before the first statement is ever released?

🔋 Huge day for Australian battery technology.

Sicona Battery Technologies has secured a $45 million ARENA grant to build Australia's first commercial-scale silicon-carbon battery anode production facility in Port Kembla, putting Wollongong firmly on the global battery supply chain map. 🇦🇺

Their SiCx® technology charges up to 40% faster and delivers 20% more energy density than conventional graphite, all while working with existing battery manufacturing lines.

We're incredibly proud to have supported this announcement, coordinating a national PR campaign that helped put this milestone in front of Australia's biggest media outlets.

Congratulations to Christiaan Jordaan, the entire Sicona team, ARENA, BlueScope, and everyone who helped make this happen. Exciting things ahead. ⚡

Last week, Third Hemisphere was proud to support a fundraising evening for Parents for Climate at The Pillars.

For our Managing Director, Jeremy Liddle, it was also an opportunity to reflect on a cause that has shaped much of his thinking around leadership, advocacy, philanthropy and responsibility.

Having served on the Parents for Climate Board for three years and now continuing as an Ambassador and Advisor, Jeremy has witnessed firsthand the organisation's evolution from a determined parent-led movement into Australia's leading parent climate advocacy organisation.

Today, Parents for Climate represents more than 26,000 supporters nationwide, empowering families to advocate for climate solutions that protect children's health, education and future opportunities.

From securing millions in funding for school solar projects to holding organisations accountable for greenwashing, the movement continues to deliver tangible outcomes for Australian families and communities.

As a certified B Corp, supporting organisations that create meaningful social and environmental impact is an important part of who we are.

Content marketing isn't getting harder because of AI.

It's getting harder because everyone can create content now.

The internet has no shortage of blog posts, LinkedIn updates, newsletters or AI-generated articles.

What it lacks is expertise.

That's becoming a problem for companies still treating content as a volume game.

Publishing more content doesn't automatically build authority.

Publishing better-informed content does.

The brands standing out right now aren't necessarily creating the most content.

They're creating the most valuable perspectives.

They're:
→ sharing original insights
→ building executive visibility
→ contributing to industry conversations
→ becoming trusted sources of expertise

And as AI search continues to reshape how people discover information, that distinction matters even more.

Because AI can generate content.

It can't generate experience.

It can't generate credibility.

And it certainly can't generate a unique point of view.

That's why thought leadership is becoming one of the most valuable forms of content marketing.

Not because it's trendy.

Because expertise is becoming harder to replicate.

We explored why thought leadership is outperforming traditional content marketing — and why the future of visibility may belong to organisations with something genuinely valuable to say.

Climate tech has a product-led growth problem.

For years, software companies have been told the same thing:

Build a great product.
Reduce friction.
Let users experience value quickly.

It worked for Slack.
It worked for Zoom.
It worked for Notion.

But climate tech isn't operating in the same market.

A carbon accounting platform isn't purchased like project management software.

A climate risk platform isn't evaluated like a collaboration tool.

Most climate software purchases involve:
→ sustainability teams
→ finance teams
→ procurement
→ legal
→ executive stakeholders

Buyers aren't just evaluating the product.

They're evaluating trust.

Can the data be defended?

Will it stand up to scrutiny?

Does it align with reporting requirements?

That's why many climate SaaS companies struggle when they borrow growth strategies from traditional software.

The companies gaining traction are often doing something different.

They're investing in:
✓ category education
✓ thought leadership
✓ industry expertise
✓ trust-building

In other words, they're growing through authority, not just adoption.

We explored why product-led growth often struggles in climate technology—and what founders should focus on instead.

Has climate tech become a trust-led market rather than a product-led one?
