“Speaking to founders in the grindstone puts me right back to starting out. If you've got experience to share, it's a shame to keep it bottled in.”

The Work

Tell us about what you do and how you got here.

I come from a bootstrap mentality, someone who didn't have money to spend on ads and marketing, so outbound was the only thing I knew. In my first SaaS company I single-handedly closed the first 500 paying clients through cold calling, outbound sales, email marketing. Those tangible lessons and experiences are what I pass on, and I'm literally following the same playbook today for my second startup, Jobtable, hitting the phones, cold calling.

I love speaking to startup founders and entrepreneurs who are just going through the grindstone. It's very nostalgic. It always puts me back into that place of just starting out. If you have insights and experiences to share, it would be a shame to keep that bottled in. Even if a mentee takes the tiniest fraction of something they can apply to their business, that's very rewarding for me.

Why Mentor

What made you join GrowthMentor in the first place?

Honestly, I joined off one random LinkedIn message about a new platform being built for founders. It sounded interesting, and I think I was one of the first OG mentors. It's been great ever since.

What hooked me is exactly what keeps me here: getting to speak with founders and entrepreneurs grinding through the early days. I've always felt that if you've got real experience, spreading it and sharing it beats keeping it to yourself. It's a lot of cool folks in this community, and helping even one of them apply a small piece of what I've learned is enough for me.

Who They Help

When a founder asks how to land their first customers, what's your answer?

It's always the same answer, no matter what company or industry you're in. How do I get my first 1, 10, 100 customers? Cold call, outbound, just speak to people directly. To me there's no better, more efficient way to get sales fast. That's exactly how I closed my first 500 paying clients, and it's what I'm doing all over again with Jobtable.

On the practical side, most of what I talk through with mentees is the specifics of outbound: how to segment your lists, how to target, the messaging, how important the content and the pitch are. The best salespeople and marketers today are the ones who understand human behavior, why people react or don't react to things. It's usually the little things in your content that make a big difference. Small things compounded can be the difference between a 10 percent and a 13 percent conversion, which is significant.

A Standout Session

You talk about sales like chipping away at a boulder. Walk us through that.

I picture sales as a giant rock in front of you, and you're a little guy on top of it just chipping away slowly. Every tweak, every adjustment is a little chip. The more chips you make, the more you eventually find a crack where a stream comes through. It's a matter of trying everything, whether it's emailing first, cold calling first, sending SMS, changing your pitch, your tone, your messaging. All of it has to be tested and tried. So when a founder asks me, personalized or at scale, my answer is all of the above. See what sticks.

The mistake I see constantly is people who try outbound with a couple of methods, it doesn't work, and they immediately jump to the conclusion that outbound doesn't work and run off to paid ads. You've got to stick with it and test different methods. The hack to sales, and really to anything in life, is consistency. At Jobtable we started selling about a month ago, and how we do sales has changed a complete 360 from day one to today, just from trying different things, being quick on the adjustments, and eventually catching your groove and doubling down on what works.

Inside the Platform

You bring up mindset even when mentees don't ask. Why does that matter so much?

When I'm speaking to someone starting out, I always talk about mindset, even if they don't ask, because I think it's that important. My mantra is no plan Bs. When I decide I'm going to do something, when I truly believe in it, there's no plan B, there's no failure as an option. You're going to figure it out and make it work. A plan B is literally a plan for failure, and the moment you instill that tiny grain of doubt, your chances of failure go up exponentially because you've already put it in your head.

When I get into that mindset on a call, I really hit people with it and you can see it land. They go, yeah, I've got to tighten up the mindset game. It sounds cliche, but it's real. You've got to have thick skin and a tough mind to start and grow a business. That's usually where I see the aha moment happen, when I talk about mindset.

What They Got Back

What do you look for in a mentee who gets the most out of a session?

The fact that they've taken the initiative to sign up to GrowthMentor and get access to all these mentors already tells me they're proactive and open to new ideas. That alone is a huge plus right out of the gate. Beyond that, you've got to be willing to put your ego down and listen to people who have experience, take in any advice you feel you can use, and always stay open to new lessons.

Honestly, I don't think I've ever had a mentee get defensive or protective about their ideas, which says something about who this community attracts. They tend to come in genuinely open. I always try to connect with mentees on LinkedIn and social afterward, and a small handful I've stayed in touch with over time. That happens organically, and it's one of the nice parts of being here.

The Filter

Do you still use GrowthMentor yourself to grow your own startup?

For sure. Just last night I sent in a help request looking for a social media marketer to brainstorm some ideas with, and I requested a couple of sessions that same morning. It had been a little while since my last one, but I've definitely tapped into the mentors myself plenty over the years.

That's the thing about this place, it cuts both ways. I'm here giving my experience on sales and bootstrapping, and when I need a second perspective on something outside my lane, the same community is right there. You don't have to keep it all in your own head.

The Verdict

Three adjectives for GrowthMentor.

Nostalgic
rewarding
genuine
