Over the past decade, I’ve scaled revenue and client success at three SaaS companies from $5M to $30M+ ARR, delivering 110%+ net revenue retention and top 10% NPS scores (65+).

Today, we help recruitment firm owners & Principals ($1M–$20M billings, 5–20 recruiters) turn LinkedIn into their #1 revenue channel by building trusted authority in their market.

Our clients don’t want to be “content creators.” They want visibility that converts into qualified pipeline and high-intent retained searches. That’s what we do.

In the past 12 months, we’ve generated $5M+ in client revenue from LinkedIn by positioning their firms as the go-to authorities in their markets.

Our methodology:
→ Revenue Growth Engine - a 3-step system perfected with 40+ founders
→ Content strategy that generates demand for retained executive searches (not just likes)
→ Strategic outreach to initiate conversations with your ideal clients and candidates
→ All requiring just 1.5 hours per week from busy Principals and founders

Our results:
→ 40+ founders and Principals served
→ $5M+ in client revenue generated from inbound leads via LinkedIn
→ 4+ qualified inquiries per month within 90 days (average client result)
→ Doubling client pipelines in under 6 months
→ Clients include 7 and 8-figure retained search firms commanding $50K+ fees and securing multi-search mandates

And we're just getting started!

We help recruitment founders who are:
→ Tired of building trust from scratch and ready for clients who arrive pre-sold
→ Reliant on a referral pipeline that has plateaued and feels unpredictable
→ Ready to turn decades of expertise into an inbound client pipeline

The talent landscape is shifting in real time.

Mass layoffs. Hiring freezes. Leaner teams:

I sat down with Gina Hadley to unpack what top CHROs and hiring leaders are doing to stay ahead.

Her company The Second Shift was just acquired by Sinecure, Inc.  — and is shifting from “flexible talent for women” → a total talent solution built for leaders designing teams that are adaptive, resilient, and capital-efficient:

• On-demand senior talent for mission-critical work
• Retained search when the role should become full-time
• Scalable recruiting for team build-outs

For CHROs and hiring managers, that means:

• Solve critical work fast without waiting on headcount
• Validate culture fit before committing full-time
• Reduce hiring risk without slowing execution

And this isn’t “send a contractor and hope it works.” 🤞

Sinecure is rolling out training, documentation, and tailored enablement to help HR leaders deploy on-demand talent successfully — KPIs, milestones, onboarding playbooks, culture integration, and more.

This is the evolution of flexible work — applied to high-complexity knowledge work.

I didn’t start posting content because I was “trying to build a personal brand.”

I posted because I was obsessed with longevity — epigenetic age tests, biomarkers, health experiments.

That was it.

Then something unexpected happened:

People started reaching out.

Even Bryan Johnson slid into my DMs after I tagged him.

That’s when I realized something most founders still miss:

• You don't need a massive audience
• You just need consistency + a POV worth sharing

Because unlike ads and referrals, content compounds.

One great piece of content can:

 • Spark conversations with dream customers
 • Position you as the trusted expert before the first call
 • Generate leads months — sometimes years — later

A founder-led content strategy isn’t about “being an influencer.”

It’s about controlling your destiny and attracting your perfect-fit clients.

B2B lags B2C by ~10 years.

Had a great conversation with Will Leatherman and he said it perfectly:

"If B2C’s creator era kicked off in 2014… B2B is right on schedule"

And the playbook is already written:

2016 → B2C social goes mainstream
2019 → Personal brands disproportionately outperform corporate brands
2020s → Distribution > product

Now the same shift is hitting B2B.

Founders & CEOs are becoming the face of their products & services.

Those who start now will be 2–3 years ahead by the time everyone else catches on.

90% of your future customers will never like, comment, or share your content.

And they'll still buy from you.

Last month we analyzed booking data across our clients. Sales calls, demos, strategy sessions.

The pattern was clear: 4 out of 5 people who booked had never engaged with a single post. No likes. No comments. Nothing.

They'd been watching the entire time.

I talked with a SaaS founder last week who was ready to quit posting. "I'm getting 20 reactions per post. Feels like I'm shouting into the void."

Three days later, someone booked a demo. First conversation ever. The prospect said: "I've been following you for 6 months. I know exactly how you work."

Zero prior engagement.

Here's what we've seen: The decision-makers - the ones with budget authority— they're professional lurkers. They don't engage. But they're paying attention.

The recruiting firm owner who lands a $125K retained search from someone who never engaged once.

The agency founder whose biggest client watched silently for 90 days before reaching out.

Most founders quit in the first 90 days because they think low engagement means it's not working.

Meanwhile, hundreds of ideal customers are watching, evaluating, building trust invisibly.

The best leads aren't engaging. They're watching.

And when they're ready, they'll reach out.

The question is: Will you still be showing up?

B2B marketing runs 10 years behind B2C. 

Which means the future is obvious:

2014 → Ryan Reynolds buys Aviation Gin. 

Sells for $610M. Then Mint Mobile. Then Wrexham FC. 

2017 → Rihanna launches Fenty. Billion-dollar brand in 3 years.

George Clooney, Dwayne Johnson, Kim Kardashian… 

Same playbook: Build audience → Launch product → Print money.

Now it’s happening in B2B:

Brian Chesky turned Airbnb into a movement by telling the story himself.

Dharmesh Shah & Brian Halligan coined “Inbound” and built HubSpot into a category by educating the market at scale.

Jason Lemkin built SaaStr into the #1 SaaS community — deal flow, partnerships, LPs, and talent on demand.

Patrick Collison turned Stripe into the intellectual hub of tech — through essays, open source learning, and ideas.

The founders with distribution are winning everywhere:

• Faster sales cycles, higher ACVs
• Inbound pipeline, not chasing demos
• Category authority vs vendor energy
• Better talent, investors, & partnerships
• Demand that compounds instead of resets every quarter

This is no longer a “content strategy.” It’s an unfair advantage

And right now?

Most B2B founders are sitting on the sidelines waiting for:

❌ The "right" time (it was 2 years ago)
❌ More clarity (it comes from action, not waiting)
❌ Confidence (built by publishing, not planning)

In 12-24 months, B2B will be saturated with founder-creators.

The 1% publishing today are capturing the hearts, minds and wallets of their customers. 

What are you waiting for?

Helping recruiting agency owners get new clients with done-for-you LinkedIn content | Podcast host at Founder-Led

Most CEOs think pipeline is built in their CRM.

It’s not.

Right now, somewhere, your future buyer is listening to a podcast where your competitor gets mentioned. Another is reading a LinkedIn post that positions someone else as the category leader. A third is in a Slack community asking for recommendations — and your name isn’t coming up.

None of this shows up in your attribution dashboard.

This is what Chris Walker and others call the 'dark funnel' — the invisible network of conversations, content, and word-of-mouth that actually drives 60–80% of B2B buying decisions.

Here’s what few people understand 👇

B2B buyers don’t discover you through:

 • Gated eBooks
 • Paid search
 • SDR outreach

They discover you in places attribution software can’t see:

 • Podcasts
 • Founder content on LinkedIn
 • Niche industry communities
 • Private group chats
 • Word-of-mouth between peers
 • “Here’s how we use XYZ tool” Zoom conversations

Buyers are learning from your content and from each other.

They already know:
 • How your product works
 • Where it fits in their stack
 • The aha-moment use cases
 • The lift you deliver

Before they ever speak to you.

The dark funnel isn’t small — it’s where 70–90% of the buying journey now happens.

And because founders can’t measure it… they don’t invest in it.

78% of executive buying decisions now involve online research before the first sales call.

Companies leaning into dark-funnel channels are seeing 50–67% shorter sales cycles.

But most executives hold back because:

 • It can’t be measured like traditional channels
 • It requires creativity — more art than science
 • It feels risky because it's a new paradigm

And that’s the opportunity.

You’re not competing on product anymore. You’re competing on who educated the buyer first.

The dark funnel isn’t new — it’s how consumers have been buying for decades.

What’s new is that it’s now where the majority of B2B buying decisions start.

And if you’re not showing up where it counts, you’re not in the consideration set.

If this resonates and you want to start winning inside this new paradigm, DM me and I’ll send you the playbook we’ve developed after working with 40+ businesses.

It takes 2 hours per week and compounds faster than any other marketing channel when done right.
