Contentellect: Buy Out Your Co-Founder, Grow Revenue 3.6x in Two Years, Then Sell Before AI Arrives — Three Moves
SEO content agency Contentellect bought out its co-founder in 2021 and grew revenue from $250K to $900K in two years. Seeing that "AI will break this industry," the founder sold to listed holding company Onfolio for $850K (2.5x EBITDA) in April 2023. A case study in knowing when to run.

Why This Exit Is Unusual
Most M&A stories can be explained by “it grew, so it sold.” What makes Contentellect’s exit unusual as teaching material is that the reason for selling was “it was growing, but I could see the future in which it breaks.” Just five months after ChatGPT’s release, the founder (sitting in an SEO content agency, the business closest to the blast radius of AI) let go of the business he had just scaled, for roughly 1x revenue. And the buyer bought it precisely because they judged that “AI is not a threat.” It is a transaction in which seller and buyer looked at the same facts and reached opposite conclusions.
The Business’s Journey
| Period | Event |
|---|---|
| Backstory | Mark Whitman, originally from Cape Town, worked as a management consultant in London → read “The 4-Hour Workweek” and became a digital nomad. Ran affiliate and lead-gen businesses while moving through Southeast Asia and Latin America |
| 2018 | Founded Contentellect with childhood friend Marc Bromhall (annual revenue about $250K). Bromhall was CEO; Whitman was investor and advisor |
| July 2021 | Bought out the co-founder (the original CEO) at an agreed price, becoming sole owner |
| 2021–23 | Expanded the target market from SaaS to SEO agencies and digital businesses in general; with a network of 40 freelancers, reached $900K annual revenue and $340K EBITDA |
| November 2022 | ChatGPT released. The decision to sell accelerated |
| April 2023 | Sold to Onfolio Holdings (publicly listed) for $850K (about 1x revenue, 2.5x EBITDA). The reason: “It was certain that rapid technological change would break the industry” |
| Afterward | Acquired adventure-travel booking company Skyhook. “I can’t sit still for five minutes” |
An Agency as the Culmination of Nomad Entrepreneurship
Whitman’s business style has been consistent since the backstory. After quitting his management consulting job in London to become a nomad, what he built were affiliate sites and SEO content businesses — all models that run on organizing a “network of affordable English-speaking freelancers.” Contentellect was the culmination: it started with article production for SaaS companies and expanded into link building, journalist outreach, and bulk SEO campaigns of 50 to 1,000 articles.
Move One: Buying Out the Co-founder
At founding in 2018, the CEO was his childhood friend Bromhall, while Whitman stayed one step back as investor and advisor. In July 2021, Bromhall wanted out, and Whitman bought his stake at an agreed price. This was just when COVID-19 had battered Whitman’s investments in the travel sector, so the motivation to settle in and run the business himself was fully in place.
This buyout laid the foundation for everything that followed. As sole owner, Whitman broadened the customer target to SEO agencies and digital businesses in general, growing annual revenue 3.6x from $250K to $900K in two years.
The Business’s Numbers (at Sale)
| Item | Figure |
|---|---|
| Annual revenue | $900,000 (about ¥135M) / EBITDA $340,000 (about ¥51M) |
| Team | 11 employees + 40 freelancers |
| Customers | 60 companies (one-third on recurring contracts) |
| Sale consideration | $850,000 (about ¥130M), in cash |
Moves Two and Three: Scale Up, Then the Fastest Possible Retreat
On the reason for selling, Whitman is unequivocal: “It was certain that rapid technological change would break the industry.” After ChatGPT’s release in November 2022, he could have pivoted the freshly scaled business toward the AI era, but he chose an immediate sale instead. In April 2023, the deal closed with listed holding company Onfolio Holdings at $850K, roughly 1x revenue and 2.5x EBITDA.
The buyer’s read is the interesting part. Onfolio CEO Dominic Wells dismissed the AI threat: “Most customers don’t want to use AI, and when they do, the output quality isn’t good enough.” The modest 2.5x EBITDA multiple can be read as the gap in risk perception between the two parties expressed directly in the price. The seller looked at the tail risk and took certain cash. The buyer looked at near-term cash flow and bought cheap. Which one was right will be decided by the SEO industry’s next several years.
How to Read These Three Moves
He let go of a “business AI will break” before it broke, a textbook on timing. Selling in April 2023, five months after ChatGPT’s release, was the fastest possible pricing-in of the structural change coming to bulk SEO content production. Alongside Investor Junkie’s sale at “the ceiling of its current form” and The Neuron’s sale early in the boom, technological change functions as a sell signal.
Buy out the co-founder → grow rapidly solo → sell: three moves in capital. Without the 2021 buyout, the $850K consideration would have been split, and the growth strategy would likely have remained contested. Like DashThis’s buyback of its CEO’s stake, cleaning up the cap table before the sale is a precondition for selling high.
A service business’s sellability comes down to “process + recurring customers.” A hiring, quality-control, and delivery system for 40 writers was running, and one-third of customers were on recurring contracts, a business that runs without the founder, which created a “sellable asset” rare for an agency. It shows that beyond an individual selling skills on Coconala lies a path of team-building → systematization → sale.
Points to Discount
The $850K consideration is the figure before deducting the cost of the 2021 stake buyout. Since the buyout price is undisclosed, Whitman’s net proceeds cannot be calculated from outside. And while 2.5x EBITDA is not unusually cheap for a service business, a SaaS with the same profit would fetch a multiple several times higher, exits for service businesses must be planned with this low multiple as a given.
The speed of the sale also depended on the market. Closing five months after ChatGPT’s release was possible because the English-speaking market has listed holding companies like Onfolio that buy small online businesses on a continuous basis, and agencies of the same size do not enjoy that liquidity in every market.
Nor can the sale rationale itself, “AI will break the industry”, be verified from this one transaction. It remains possible that Wells’s read (customers won’t use AI, or can’t) is right in the short term. All that can be said with certainty is the consistency of Whitman’s behavior: rather than keep betting on an uncertain future, he chose certain cash and moved his next capital into travel (Skyhook), a domain far from AI.
