Christopher Kai had already built a significant career before publishing Big Game Hunting. He’s the founder and CEO of The Mathem Group, a Beverly Hills–based leadership training firm. He’s a former business strategist and executive speechwriter at American Express. His client roster includes Google, American Express, New York Life, Merrill Lynch, Farmers Insurance, Bank of America, and the U.S. Consulate.
He’s also the founder of GPS, the premier speaker training program in the world, with clients in more than 100 cities across 24 countries and five continents.
And he doesn’t just teach high-level networking — he lives it. The connections he’s made over his career include meeting in person Elon Musk, Richard Branson, and other figures most people only read about. When Musk once exclaimed during an interview with Christopher, “Wow, you really know a lot,” it captured something specific about the level at which Christopher operates.
In addition to his consulting and speaking work, Christopher is the founder of Mondays at the Mission — a homeless youth program at the largest private shelter in the United States, with 240+ program speakers from 26 states and 28 countries (including Elon Musk, Moby, and TED speaker Diana Nyad). The program has been featured on CNN, People, ABC, Time, the Ellen DeGeneres Show, and Oprah.
He had already authored multiple books before working with Authors Unite. He had the credentials and the speaking experience. What he hadn’t yet done was take Big Game Hunting — his framework on networking with people most consider unreachable — and give it the kind of launch that would make it a recognized authority text on the topic.
For Christopher, Big Game Hunting wasn’t just one more book. It was the codification of a specific method — how to network with billionaires, executives, and celebrities through a four-step process of preparation, event presence, and follow-up that he’d refined over the years.
He wanted three things from the launch:
First, to give the book the credibility that would let it stand as the authoritative reference on high-level networking — a category that’s full of weak books and short on serious ones.
Second, to use the bestseller credential as a credentialing asset for his core business. Christopher’s primary revenue isn’t book royalties — it’s speaking, training programs, and consulting. A bestseller credential would compound his ability to charge premium rates and book serious gigs.
Third, to put the framework in front of an audience far beyond his existing reach. To deliver on all three, the launch needed to do the specific thing that defines a real bestseller campaign: drive a lot of qualifying purchases concentrated into a single reporting week.
That’s what he hired Authors Unite to deliver.
Authors Unite ran the coordinated bestseller campaign for Big Game Hunting — built around the same two core levers we use for every campaign:
Email marketing at scale. Driving a lot of qualifying retail purchases concentrated into a single reporting week requires high-volume, high-conversion email infrastructure. Authors Unite ran the campaign’s email work.
Paid ads. Coordinated paid advertising designed to compound with the email-driven sales velocity and ensure purchases were concentrated during the target reporting week.
That’s the work. Email marketing and paid ads, executed at the scale and timing required to make Big Game Hunting a #1 Bestseller.
Christopher brought everything else: the framework, the years of high-level networking experience, and the book itself. Authors Unite ran the launch mechanics.
The campaign delivered the concentrated sales velocity required to make Big Game Hunting a #1 Bestseller.
But the more interesting story is what happened next.
In Christopher’s own words: after Tyler launched his book to bestseller, he landed his first $30,000 keynote speech.
That’s worth being precise about. Authors Unite didn’t book the keynote. We don’t do speaker booking. What we delivered was the bestseller credential — the asset that made it credible for Christopher to charge that fee and for the booking party to pay it.
The credentials mattered. As we have written elsewhere about bestseller campaigns, bestseller status typically allows serious nonfiction authors to charge 2-5x more for speaking engagements. Christopher’s experience is a concrete data point on what that looks like in practice. Pre-bestseller speaking fees in one range; post-bestseller speaking fee at $30,000.
Since the launch, Christopher has continued to grow his speaker training business (GPS), his consulting practice (The Mathem Group), his philanthropic work (Mondays at the Mission), and his speaking career. Big Game Hunting remains a reference text on high-level networking, and the bestseller credential is part of how Christopher is now positioned across the board.
“After Tyler launched my book to bestseller, I landed my first $30,000 keynote speech. I could not have done this without Tyler’s help. If you’re looking for a team that can help you write, publish, and market your book... Authors Unite is it.”

Big Game Hunting: Networking with Billionaires, Executives, and Celebrities is Christopher Kai’s framework for connecting with people most consider unreachable. The book reverses the standard “how do you network better?” question and instead identifies the 20 most common mistakes people make when trying to meet “Big Gamers” — people in positions of influence — and how to avoid them.
It covers the practical mechanics: how to define your ideal “Big Gamer,” how to find events where they appear, how to approach them with confidence, what to do during the conversation, and how to follow up in a way that turns a single encounter into a relationship.
The book has earned endorsements from Nolan Bushnell (founder of Atari and Chuck E. Cheese’s) and Tim Chang (Managing Director at Mayfield Fund, on Forbes’ Midas List of Tech’s Top Investors), among others.
Christopher Kai’s case demonstrates two specific things.
First: when an author with a real framework hires Authors Unite to run a coordinated bestseller campaign, we can produce the concentrated launch-week sales velocity required to make the book a #1 Bestseller.
Second: the bestseller credential is more than a vanity metric. For nonfiction authors with downstream revenue — speaking, consulting, coaching, services — the credential can pay for itself many times over. Christopher’s $30,000 keynote is one data point. Multiply that across the years, a bestseller credential remains active, and the ROI on the launch campaign starts to look very different from “did the book earn back its launch cost in royalties?”
If you’re a speaker, consultant, or business expert whose primary revenue lives downstream of your book — and you want the bestseller credential that compounds with the rest of your business — let’s talk.
