I own about 500 domain names. Most days I think about them as inventory. Every so often I flip it around and ask a different question: if I had to stop selling and start building, which ones would I pick up first?
The answer has stayed fairly stable for a few months now. Five names keep coming back, because each one sits on a market that is already spending money and each one says what the business does in plain words. Here they are, with the business I’d build, the buyer I’d expect to want it, and the first product I’d ship.
Reelcasts.com, a Home for Serialized Short Video
Creators on Instagram, TikTok and YouTube Shorts now make series. Recurring characters, numbered episodes, cliffhangers. What they don’t have is a word for it, or an address that belongs to them. A podcast lives on an open feed anyone can subscribe to; a reel lives inside an app whose algorithm decides who sees episode eleven.
The money is already there. Omdia puts global microdrama revenue at about $11 billion in 2025 and about $14 billion by the end of 2026, with the US alone worth roughly $1.5 billion of that. Those apps sell episodes one coin at a time, and they proved that people will pay for vertical, serialized stories. Creator-made series are the next layer, and they need a place to live.
The business I’d build is a directory and show-page service for reel series. A creator connects their accounts, groups clips into seasons, and gets one page at reelcasts.com/showname that fans can follow regardless of which app the clips sit in. First product: the show page, plus a weekly chart of the fastest-growing series. The buyer is a creator platform, a short-drama studio, or a network signing creators to serialized shows. I made the full case in Reelcasts are the next podcasts, and the short version is simple: podcast.com was once just a word nobody had used yet.
PhotoVideoMaker.com, the Name the App Stores Already Search For
Type “photo video maker” into Google Play and count the apps that cram those exact words into their titles. People have searched the phrase for years to turn a camera roll into a clip with music. AI has made it bigger. A photo is now the first frame of a video; Google Photos animates stills, Midjourney has an Animate button, and AI video generators sit in the Photography category on Google Play.
Investors noticed. Higgsfield, which turns prompts and still images into short video, raised $400 million at a $5.4 billion valuation in August. That’s the category this name describes word for word.
I’d build a consumer app with a web checkout: drop in photos, pick a style, get a finished reel with music and captions, pay for credits on the site. The domain matters more than it used to, because Apple now lets US apps send users to pay on the web, and a checkout page converts better when its address matches the app’s name. The natural buyers are an AI video company getting ready for a consumer launch, or a photo editor adding video that wants one name covering both. More detail is in Every photo app is becoming a photo video maker.
Aftermarket.dev, Parts and Service for Software After the Vendor Leaves
Software gets abandoned all the time. A maintainer burns out, a framework version reaches end of life, a vendor shuts down an API. The code that depends on it keeps running in production, and the risk piles up quietly until an audit or a vulnerability forces the issue.
This is a real business. HeroDevs, which sells security patches for end-of-life open source frameworks, raised $125 million from PSG in 2025 and says more than 900 organizations use its products. Regulators are pushing the same way; the EU’s Cyber Resilience Act makes vendors answerable for the components inside what they ship, and an unpatched dependency is now a compliance problem as well as a technical one.
Cars solved this long ago. When the maker stops supplying parts, the aftermarket steps in. Aftermarket.dev borrows that word for developers, and the .dev ending tells them who the site is for before it loads. The first product I’d ship is a scanner that reads a project’s dependency file, flags anything abandoned or past end of life, and points to a maintained fork or drop-in replacement. Paid tiers would add patched builds and compatibility shims for retired APIs. The buyer is a security company, a dependency-tooling startup, or a long-term-support vendor that wants a brand developers remember. The listing is at Aftermarket.dev is where abandoned software gets a second life.
HomePremise.com, for the Home That Became a Workplace
About 26 percent of paid full workdays in the US were worked from home in July 2026, according to the WFH Research survey. That share has held through every return-to-office push. For tens of millions of people the home is a place of business now, whatever the mortgage papers say.
Insurers, landlords and lawyers have a word for a place of business: premises. HomePremise.com puts it next to “home”, and the phrase covers the whole shift. The harder questions have moved past the desk anyway. They’re about rooms. Two people sharing one room for calls, a studio flat where work and sleep share a wall, a rental where nothing can be screwed into the plaster.
My first product would be a paid room-planning service: upload a floor plan and a few photos, get a layout, a lighting plan and a shopping list sized to the actual space. The site already publishes original room concepts and practical guides on homepremise.com, so the content engine exists. Buyers I’d expect: a furniture retailer moving into planning services, an insurer covering home-based businesses, or a design studio running remote consultations.

RefurbishedContainers.com, the Trade Between a Used Box and a Finished Room
A shipping container retired from ocean service is one of the cheapest structures you can buy. Turning it into something people want to sit in all day is a trade of its own: cutting and framing openings, treating rust, replacing the floor, insulating, wiring, lining. Dealers call that work refurbishment, and they charge well above the as-is price for it.
The wider container-building market is large and growing. IMARC values container homes at about $63 billion in 2025 and expects about $96 billion by 2034. Inside that, garden offices, workshops, farm shops and small cafes keep pulling in new buyers, and every one of those projects starts with a sound, prepared unit.
The business I’d build is a graded marketplace. Each unit gets inspected, rated and photographed before listing, with refurbishment packages quoted up front, so a buyer knows what they’re getting before the truck shows up. A regional refurbisher, a container dealer with a conversion yard or a modular studio maker would get a name that is simply their job description. The working site at refurbishedcontainers.com already publishes design concepts and planning guides, and the listing is at RefurbishedContainers.com names the category between a used box and a finished room.
What the Five Have in Common
None of these needs explaining. Read the name once and you know the business. That’s worth a lot when a startup is paying for every click, because a name that matches what people already type does part of the marketing for free.
They also pair up nicely. HomePremise.com and RefurbishedContainers.com serve the same person deciding where the working day happens; a container in the garden is often the answer to the home office question. Reelcasts.com and PhotoVideoMaker.com sit at two ends of the same creator pipeline, one making the video and one giving the series a home. Aftermarket.dev keeps the software underneath all of it running.
If I had a free year and a small team, I’d start with one of these. Someone with more of both could start with all five.
