Tiny's acquisition screen starts with a blunt question: is this business so good that the new owner will struggle to mess it up? Wilkinson looks for structural durability rather than a management plan that promises to repair a fragile model. The favored defenses are a trusted brand with pricing power and a network effect that makes the product more valuable as more people join. High switching costs can also protect a company, though he finds that moat less customer-friendly. Management matters because Tiny generally leaves acquired companies alone; the main intervention is installing a CEO when a departing founder requires one. A passing business has loyal users, a clear competitive advantage, operational independence, and enough staying power to hold for many years.
Origin
After finding startup failure stressful, Wilkinson read about Warren Buffett and shifted from constantly starting companies to buying durable ones. Tiny now owns more than 40 businesses and usually leaves an acquired company's existing operation unchanged.
Core principles
- 01The best acquisition is difficult for an owner to damage.
- 02A moat protects demand and pricing from competitors.
- 03Brands and network effects create durable customer pull.
- 04Existing management reduces transition risk.
- 05Long-term owners should preserve what already works.
How to run it
- 1
Stress-test fragility
Ask what happens if a key person leaves or the owner stops intervening. Reject companies held together by one indispensable individual or by constant improvisation.
Pro tip Look for a business that keeps working before imagining how you will improve it.
Watch out A brilliant management team cannot reliably overcome a structurally bad business model.
- 2
Name the moat
Require a specific mechanism that protects the company from competition. Wilkinson prioritizes strong brands, network effects, and—in a less preferred form—high switching costs.
Pro tip Describe why a customer stays and why a competitor cannot cheaply copy that reason.
Watch out Calling customer satisfaction a moat does not explain durable protection.
- 3
Verify management continuity
Determine whether an existing team can keep running the company after the transaction. If the founder plans to leave, CEO selection becomes the buyer's most important operating decision.
- 4
Test long-term staying power
Assess whether the moat, user behavior, and economics can persist over a long holding period. Favor assets whose competitive position strengthens rather than resets each year.
Pro tip In a network business, ask why users would move to a smaller rival when their friends are already on the incumbent network.
- 5
Preserve the working system
After buying, make as little visible change as possible unless management continuity requires action. Treat restraint as part of the acquisition thesis.
Pro tip Write down the few changes that are truly necessary before the deal closes.
Watch out Acquisition ownership is not evidence that the buyer understands the business better than its operators.
In the wild
Wilkinson saw that Letterboxd had become a large social network for film lovers. A new competitor would need to persuade users to leave the place where their friends and reviews already existed, giving Letterboxd a network-effect moat.
→ Tiny acquired a passion-aligned company with a defensible community and long-term staying power.
Tiny's recent Serato acquisition fit Wilkinson's own DJ experience. He saw a large, passionate user base and deep hardware integration in the leading DJ software, which made the business harder to displace.
→ The target combined founder understanding with concrete competitive protection.
Common mistakes
Buying a business you plan to rescue
The screen seeks an operation already strong enough to endure ownership, not one that depends on a brilliant turnaround plan.
Using a vague moat label
A durable advantage must explain pricing power, retention, or competitive resistance through a specific mechanism.
Changing the company to prove ownership
Tiny generally leaves companies alone because unnecessary intervention can damage the qualities that justified the acquisition.
Is it for you?
Best for
It is best for long-term buyers seeking profitable companies that can keep operating without intensive intervention.
Not ideal for
It is not ideal for turnaround investors whose return depends on restructuring a weak business model or replacing most of the operation.
