Will everyone have their own software?
Software is sliding down the long tail, from every industry to one person. What Space learned building a super app for agencies, a company, teams, and people.


TL;DR
- Software gets more specific as it gets cheaper to build. The long tail now reaches one person.
- In early 2025, a quarter of Y Combinator's Winter 2025 batch had codebases that were 95% AI-written.
- Space built a super app for agencies, then for itself, then for its teams and some of its people.
- The end state is one super app per person. A new need becomes a new feature.
Yes. Software is sliding down the long tail, one level at a time. It used to be built for everyone, then for an industry. Next comes the company, the department, the team, and the person. That person ends up with one super app that grows a feature whenever they need one. Space, the AI-native brand agency, built at four of those levels in 2026. So this is a field report as much as a forecast.
Here's the tail, level by level.
Level | Built for | Example | What you give up |
|---|---|---|---|
Everyone | Any company, any job | Seats you pay for, features you skip | |
Industry | One vertical | Agency OS, built by Space for agencies | Anything your firm does differently |
Company | One company | Space's own super app, for 107 people | You own the upkeep |
Department | One function | A finance team's month-end tracker | Fit with other departments' tools |
Team | One team | Space's project board for its project managers | Easy handoffs to other teams |
Person | One human | Space's email ghostwriter, which drafts in each person's voice | Help from anyone else who knows the tool |
Why is software getting more specific?
Building it got cheap. In March 2025, Garry Tan of Y Combinator told CNBC that about a quarter of the Winter 2025 batch had 95% of its code written by AI. When code costs that little, a tool no longer needs a million buyers to pay for itself.
Chris Anderson named the long tail in Wired in 2004. His point was about shelf space. Once shelves stopped being scarce, niche books and songs found buyers. Code is going the same way, two decades later.
Software for one person isn't a new idea. In 2020, the novelist Robin Sloan wrote An app can be a home-cooked meal, about a messaging app he built for his family. Nobody else can install it. What changed since then is who gets to cook. Sloan can code. Most people couldn't, until models started writing the code for them.
What does each step down the tail look like?
Space has built at four levels this year. Each step cut more bloat. Each one fit tighter.
For an industry
Space built Agency OS for agencies. It's a super app with an agency's jobs in it: time tracking, invoices, a CRM, contracts, video review, scheduling, and dictation, on one database.
For one company
Then Space tuned it for itself. The super app replaced 28 apps Space paid for, from Loom to Smartsheet. With 107 people in the collective, every seat Space stopped renting was real money.
For teams
Next came team versions. Space's project managers got their own board, rebuilt from Smartsheet and tied to the timer. Every project phase is now something you can log hours against.
For people
This is the level I care about most. Software started with millions of users per app; here it's one. Nobody starts from zero, though. A person begins with the team's version, then changes what doesn't fit them.
Some of it is already built in. Each person switches features on for themselves. The email ghostwriter drafts Gmail replies in that person's own voice (it never hits send). The dictation app follows each person's style rules; I use it 50 to 100 times a day.
The tip of the long tail is a party of one.
Why does the tail end in one super app?
A person's tools need to share what they know. Your calendar, your clients, your hours, and your notes all describe the same week. Split across 10 apps, they drift apart. On one database they stay in sync, so a new need becomes one more feature in the same place.
For a mass market, a super app is a bad bet. One app for a million people turns into fourteen average tools. (I made that case in should an agency build its own super app?.) Built for one person, the math runs the other way. Each tool does the exact job that person has, with nothing else in it.
What could stop it?
Two things could slow this down.
The first is the specialists. Lotus Notes put email and custom apps on one database in 1989. It then lost each piece to a better standalone tool. A personal super app survives only if every tool in it beats the rented version for that person. Models improve every month, so somebody has to keep sharpening.
The second is other people. Your software can be yours alone. Your invoices and calendar invites still land on someone else's screen. So I'd bet the edges of everyone's super app stay boring for years (email, PDFs, calendar files, e-signatures), even as the middle gets strange.
When should a team move one step down the tail?
Score each signal from 1 to 5, then weight it.
Signal | Weight | What a 5 looks like |
|---|---|---|
Daily use | 35% | The team opens the tool every working day |
Workarounds | 30% | People keep a spreadsheet next to the tool to fill its gaps |
Per-seat cost | 20% | Seats show up as their own line in the budget |
Change rate | 15% | The workflow changes every quarter |
A weighted score above 3.5 says build the team version. Below 2.5, keep renting.
Who is each level the wrong call for?
- Generic software is the wrong call for a team whose workflow is its edge.
- Industry software is the wrong call when your firm wins by working unlike its peers.
- A company super app is the wrong call if nobody owns the upkeep.
- Team and personal builds are the wrong call for work that has to live in a client's tools. Some enterprise clients can't approve a third-party app.
- Space is the wrong call if you want a rented tool with a support desk and an SLA.
If you're deciding which tool to pull in-house first, say hi anytime.
Frequently asked questions
- What is personal software?
- Personal software is an app built for one person's work that nobody else uses. AI usually writes most of the code, so it changes whenever its owner's needs do.
- Why is software becoming more specific?
- Building software got cheap. In early 2025, about a quarter of Y Combinator's Winter 2025 startups had codebases that were 95% AI-written, so a tool no longer needs a mass market to pay for itself.
- What is a super app?
- A super app is one app that holds many tools on one shared database. The tools share data and a single login, so nothing drifts out of sync between them.
- Will personal software replace SaaS?
- Not soon. Generic SaaS keeps the head of the long tail, where millions of people need the same tool. The shared edges, like email and calendar files, will stay standard for years.
- Has anyone built software for individuals inside a company?
- Yes. Space, the AI-native brand agency, runs a super app for its 107 people. Each person switches features on for themselves. Its email ghostwriter drafts replies in each person's own voice.
