The mental model is a micro version of Amazon Web Services: a cost center you were forced to build for yourself, turned into a business you sell to others with the same problem. It starts with reading your own P&L. Every recurring outflow is a candidate — you've already validated the need exists (you're paying for it) and vetted the operator (you know if they're good). The move is to productize: partner with the vendor, turn the service into a real business, and keep paying them while owning the upside. Bloom's edge is that his media platform sits over everything as a halo, driving leads into each business, so he can invest with cash, with distribution, or both. Structure depends on where you catch the business: found it from the ground up, invest cash-plus-platform into an existing one, or buy outright. He keeps them bootstrapped, profitable, and CEO-run, with monthly distributions flowing to the holdco for reinvestment.
Origin
Bloom encountered the Amazon Web Services case study around 2018-2019: Bezos built enormous back-end compute to power Amazon's e-commerce business — a huge cost center — then realized a growing tech ecosystem needed the same compute and rented it out. AWS became a profit center now worth hundreds of billions. Bloom asked whether a micro-micro-micro version was available in his own world.
Core principles
- 01Your recurring expenses are proof of validated demand you're already paying for.
- 02You've stress-tested the vendor as a customer — that's diligence you didn't have to run.
- 03A platform is investable capital: leads and distribution can substitute for cash.
- 04The best targets are things you could naturally drive value to.
- 05Deal structure follows where you catch the business in its life cycle.
- 06Bootstrapped and profitable from day one beats venture-style bets you can't control.
How to run it
- 1
Read your own P&L for candidates
Go line by line through recurring monthly spend and ask, for each: is there a way I could own this business rather than have it be a cash outflow every month?
Pro tip Once you hold this lens, Bloom predicts you'll spot roughly ten candidates within a month.

Filter for things you'd genuinely outsource anyway
The best candidates are the work you're bad at and don't care about. Bloom wanted only to write the newsletter — not lead magnets, paid ads, or segmentation funnels — so he paid a team to run the back end.
Pro tip Being a real, willing customer is the whole basis of the edge.
Watch out If you're not actually happy with the vendor, you have no validation to trade on.
- 3
Verify the operator as a customer first
You've had months of live evidence on whether the team is really good at this. That is diligence a cold investor would have to pay for.
- 4
Name your unique edge
Work out what you bring beyond capital — audience distribution, lead flow, SEO capability, paid marketing capability, or strategic perspective. The art of the deal is identifying the edge that makes the business bigger than it is today.
Pro tip Distribution is investable: you can invest via your energy and platform rather than cash.
- 5
Pick the structure by life cycle
Found it from the ground up (Bloom did this with a freelance consultant, productizing his service), invest cash-plus-platform into an existing business, or use holdco cash flows to buy a bigger one outright.
Pro tip Bloom notes he could raise up to roughly $50M for a bigger acquisition if the value-add case were genuinely there.
- 6
Keep it profitable and CEO-run
Install a CEO and stay at board or strategic level, not operational day-to-day. Bloom's businesses are bootstrapped, profitable from day one, and none are money-losing venture-style bets.
Pro tip Monthly distributions flowing up to the holdco give you cash to reinvest across the portfolio.
Watch out The instant you take the ops, you've bought yourself a job and destroyed the leverage.
In the wild
Bloom wanted to write his newsletter and nothing else — no lead magnets, paid ads, or segmentation funnels. He paid a freelance consultant to run the back end, and the guy turned out to be really good at it. Rather than keep paying, Bloom proposed productizing the service into a real business, partnered with the consultant and with the founder of Kit (formerly ConvertKit), and founded the company from the ground up. He still pays them every month to run his own newsletter's back end.
→ A very profitable business serving the back end of newsletters for some of the largest newsletter writers in the world — his cost center is now his profit center.
As Amazon built its bookstore and e-commerce platform, it had to build an extraordinarily large back-end compute platform — a huge cost center. Bezos's team realized that as the technology ecosystem grew, many others needed that same enormous compute power, and began renting it out. Bloom found the case study around 2018-2019 and asked whether a micro-micro-micro version applied to his own creator spend.
→ AWS became a separate company and an enormous profit center now in the hundreds of billions — and the template for Bloom's entire holding company thesis.
Common mistakes
Investing where you have no edge
Without distribution, leads, or a strategic capability, you're just cash — and cash alone doesn't make the business bigger than it is today.
Taking the operations yourself
The structure depends on partly-owned businesses with CEOs running them while you sit at board level. Absorb the ops and the whole portfolio stalls.
Productizing a vendor you're not actually happy with
The entire de-risking mechanism is that you validated them as a paying customer. Skip that and you're a cold investor with none of the edge.
Is it for you?
Best for
Creators and operators with an audience, distribution, or a genuine strategic edge plus a meaningful recurring vendor spend.
Not ideal for
Early founders with no platform, no cash flow, and no distinctive edge to invest in lieu of capital.
