Journey

2017

Age 11-12 Introduction to Crypto

It started with a few dollars of birthday money and videos about Bitcoin and Ethereum. At that age, it was not about making money yet. It was about realizing that there were worlds online where a kid could learn, participate, and start figuring things out for himself.

That first step into crypto created a pattern that would show up again later: find something interesting, study it closely, and learn by actually getting involved.

Sneaker Resells & Trading

At 12 and 13, London started Lonster Resells, buying sneakers and reselling them for profit. He used sneaker bots for major online drops, woke up at 5 or 6 in the morning for releases, and sold shoes both online and in person.

Around the same time, he launched his first e-commerce store on Shopify, testing dropshipping products and promoting them through Instagram theme page communities. There were missed drops, losses, and plenty of trial and error, but it became one of his first real lessons in timing, consistency, and making money through the internet.

The business produced more than $5,000 in profit overall, with plenty of wins and losses along the way.

At the same time, a $100 Coinbase Pro account was slowly traded up to $700+ over more than a year, mostly during school and weekends.

2020

Loncards Takes Off

At 14, London started Loncard Breaks. He was buying cards cheaply on eBay and through local card shops, cleaning them up, repackaging them into a more approachable product, and selling them back through eBay with stronger perceived value and clearer trust for collectors.

He also ran live breaks on YouTube and Instagram, selling team spots, opening boxes on stream, and shipping the right cards to the right buyers. The business made more than $30,000 in revenue in the summer alone and roughly $50,000 across the year while active.

Daily reality

During the pandemic he spent most days packing orders and biking 20 to 30 packages at a time to the post office in a giant pizza backpack.

Status vs value

Late in the year, the card market cooled and copycats arrived. A big DeFi win in T2X then brought another lesson: material purchases and excess spending did not create lasting value.

With most of his time spent at the computer, he learned how to find answers online, teach himself new skills, and improve through repetition.

2021

Trading Becomes Obsession

At 15, London broke his knee playing basketball while also dealing with a skin condition. The isolation kept him mostly at home, and trading became the one thing he could fully focus on.

He spent long hours at the computer studying charts, trading crypto, DeFi projects, stocks, and stock options. In January, he started trading stock options with a small $500 account, turning it into tens of thousands while learning leverage, risk, and discipline. As the year continued, crypto and DeFi projects became the bigger focus, leading to some of his biggest early wins and a deeper obsession with markets.

2022

Million-Dollar Hack

At 16, the momentum from 2021 carried into bigger trading wins across Avalanche, BNB Chain, Polygon, and other crypto ecosystems. London became better at reading market attention, joining higher-level trading groups, and spotting where money was moving.

That year also brought real lessons outside the charts. He bought a Porsche 944 to rebuild and flip for fun, then later bought a new Scat Pack Widebody as a personal car. The purchase quickly became a wake-up call, pushing him to take his finances more seriously and think beyond constant trading toward long-term investing and wealth building.

Later in the NFT cycle, a social engineering attack drained his wallets of holdings that would later be worth millions in present value. In response, he went deep on programming, Solidity, machine-learning experimentation, and arbitrage systems, while also beginning to study affiliate marketing more seriously.

2023

Age 17 The Marketing Era

The year after the hack became a rebuild year. London was still programming and building tools, but marketing and media started becoming the bigger focus. Some of the programs he built created decent monthly income, but the real shift was learning how to build attention and use it.

In 2023, he launched his YouTube channel around testing side hustles and sharing what happened, even when things did not work. He also started LPL Digital LLC in March, first focused on affiliate marketing, performance campaigns, and managing subcontractors. Later, the agency expanded into buying and rebuilding large media accounts to distribute offers.

The channel reached roughly 50,000 subscribers and 3 million views by the end of the year, with brand deals used mainly to fund better production rather than sell empty promises.

2023 also included futures and options trading, a real estate wholesaling attempt in mobile home parks that nearly turned into a $400,000 deal, and a successful short-lived eBay resale partnership in studio equipment.

2024

Real-WorldExposure

At 18, London graduated high school knowing college was not the path for him. He continued running LPL Digital, keeping the core business built around affiliate offers while starting to test more direct promotional campaigns with brands.

That year also led to an internship at AllView Real Estate, where he wanted to understand the industry from the ground up before buying properties himself. The role exposed him to property management, leasing, client communication, systems, and field work. He served notices, visited properties, helped with operations, and saw the side of real estate that does not show up online.

A lot of that work was uncomfortable. After years of building mostly from a computer, he was suddenly in rougher neighborhoods, dealing with real people, real problems, and situations he normally would have avoided. It broke him out of his shell and added a new layer to his character, showing him that building companies also requires real-world judgment, confidence, and the ability to handle pressure.

After several months, he stepped away to return his focus to his own companies, but the experience changed how he thought about people, operations, and building in the real world.

2025

Expansion andNew Ventures

At 19, London expanded LPL Digital and tested a sweepstakes department. The direct profit was limited, but the experience revealed the business model that changed the year. If brands could cover spend through a performance-driven structure, he could land stronger contracts and promote offers that most marketers could not access.

From there, LPL Digital moved into contract-based promotional campaigns, where brands could cover or match ad spend when campaigns were profitable. That allowed the company to move from smaller affiliate budgets into larger campaign structures with better upside.

By late May, the idea for LERO began forming after he saw a clear problem in the crypto market: users needed more transparency and clearer reasons to participate. What started as an idea became a serious company-building focus later that year, alongside more YouTube, a digital-products experiment, and the co-founding of Evolvant.

Brand-backed campaign structures helped move monthly marketing spend from tens of thousands into hundreds of thousands, with LPL Digital expanding into 5+ countries at its peak while keeping the economics attractive.

Lero became a serious commitment in August, and Evolvant was co-founded as the next long-term company-building chapter. The YouTube channel finished the year around 81,000 subscribers.

At 20, London's work became less about proving he could create results alone and more about reaching the next level through leadership, stronger partners, and real company building. After stepping back from LPL Digital into an advisory role in August 2025, his focus shifted heavily toward helping LERO get to where it needed to be.

LERO became a full-circle opportunity to build alongside his dad, who taught him what it means to be an entrepreneur, and his dad's close friend, whose son is one of London's best friends. With reputable and successful partners around the company, London helped build what LERO needed across operations, marketing, and positioning.

As the company developed a stronger foundation and a powerful marketing team formed around it, London was able to step into a CMO and advisory role. That opened the door for him to step in as CEO of Evolvant, a company built to improve influencer marketing across the brand, creator, and agency side.

Evolvant brings more clarity, structure, and purpose to an industry that needs better systems, while also playing a key role in helping the LERO name spread across social media.
