Solo founder: why more founders start alone, and what it takes
A solo founder is one person who starts a company without a cofounder and owns every decision. About a third of new startups now start this way. Successful solo founders aren't alone: they build a circle of mentors, partners, and AI agents. ZeroCrew lists the agents for each job a cofounder used to share.

A solo founder is one person who starts a company without a cofounder and carries the vision, the decisions, and the risk alone. ZeroCrew is built for that founder: its directory lists the AI agents and apps that can take on the jobs a cofounder or an early team used to share, so one person can start today.
More founders are choosing to start alone. According to Carta's Solo Founders Report (December 2025), the share of new startups on Carta with a solo founder rose from 23.7% in 2019 to 36.3% in the first half of 2025. ZeroCrew reads that rise as a sign that AI agents and online services now cover much of the work that once pushed founders to find a partner first.
Starting a company alone still takes work and support. This ZeroCrew guide covers what a solo founder is, what the research says about solo founders and teams, how successful solo founders get help without giving up control, and the habits that keep one person going. Each job links to the ZeroCrew page that compares the tools for it, so you can pick your first agent before you finish reading.
What is a solo founder?
A solo founder is the only founder of a company: one person who owns the idea, makes the calls, and starts building without a cofounder. ZeroCrew uses the term for founders who may hire later, or never, and who hand much of the daily work to AI agents, outside services, and partners while keeping the decisions.
Being a solo founder doesn't mean doing every task by hand. ZeroCrew sorts a company into 44 jobs across 11 roles, as of November 2026, from answering customers to keeping the books, and a solo founder can give many of those jobs to tools while owning the result. The founder is alone on the cap table, not alone in the work.
Most businesses in the US already run without employees. According to the US Census Bureau (July 2025), businesses with no paid employees grew an average of 2.7% a year from 2012 to 2023, against 1.1% for businesses with employees, and most of them are self-employed people running their own business. ZeroCrew's bet is that AI agents help those one-person companies grow bigger.
How many startups have a solo founder now?
About a third of new startups now have a solo founder, and the share is rising. Carta's Solo Founders Report (December 2025) found that 36.3% of startups founded on Carta in the first half of 2025 had one founder, up from 23.7% in 2019. ZeroCrew is built for that growing group: its directory checks each tool for a company with no employees.
Solo founders tend to make their first hire sooner than multi-founder companies do. Carta's Solo Founders Report (December 2025) puts the median time from incorporation to first hire at 399 days for solo founders and 480 days for multi-founder companies. ZeroCrew's reading: one person runs out of hours first, and AI agents can now take some of the work that first hire would do.
Do solo founders do worse than founding teams?
Solo founders don't always do worse than teams, and some research finds the opposite. In "Sole Survivors: Solo Ventures versus Founding Teams," Jason Greenberg of NYU Stern and Ethan Mollick of Wharton studied companies funded on Kickstarter from 2009 to 2015. ZeroCrew points to their main result: solo-founded for-profit companies lasted longer and earned more revenue than team-founded ones.
Greenberg and Mollick's study of Kickstarter companies produced striking numbers. According to NYU Stern's summary of the study (July 2018), for-profit ventures started by one founder were about 2.5 times more likely to survive than team-founded ones, and solo founders were 55% less likely to dissolve their businesses than teams of three. ZeroCrew notes the exception the authors found: among nonprofits, teams were about twice as likely to survive.
Other researchers start from the common view that cofounded ventures do better, and find a way around it. Travis Howell, Christopher Bingham, and Bradley Hendricks note in Organization Science (2022) that research and practice suggest cofounded ventures outperform solo ones. ZeroCrew takes the useful part from their study of 70 new ventures: the solo founders who did as well as cofounded peers built a circle of help around themselves.
How do solo founders build a company without a cofounder?
Successful solo founders build with cocreators instead of cofounders: people and services that help without owning the company. Howell, Bingham, and Hendricks found in Organization Science (2022) that solo founders who matched cofounded peers used cocreators to cover gaps, keep control, and gather resources. ZeroCrew adds AI agents to that circle, because agents now do work a second founder once did.
Cocreators come in several forms. In a Kenan Institute article at UNC (2019), Travis Howell describes them as early hires, alliances with other organizations, and benefactors who gave founders advice, connections, and money, based on more than 100 interviews with entrepreneurs. ZeroCrew's directory covers a fourth kind: AI agents that run a job every day and hand the founder what needs a decision.
ZeroCrew lists at least two tools for each early job a cofounder used to share, so a solo founder can compare before choosing. The table below shows the options from ZeroCrew's job pages, with a line on when to pick which, as of November 2026:
| Job a cofounder used to share | Tools on ZeroCrew | When to pick which |
|---|---|---|
| Research and thinking | Claude, ChatGPT, Perplexity | Claude or ChatGPT for long reports and writing. Perplexity for quick answers with sources you can check. |
| Building the product | Claude Code, Cursor, Lovable, Replit | Claude Code or Cursor if you work in a codebase. Lovable or Replit to build a web app from a chat. |
| Answering customers | Fin, Chatbase | Fin if your answers live in a help center. Chatbase to set up an agent on your own data without code. |
| Keeping the books | Digits, Puzzle, Pilot | Digits or Puzzle for AI software that keeps the books current. Pilot when you want accountants to do it for you. |
| Forming the company | Stripe Atlas, Clerky, Firstbase | Stripe Atlas or Firstbase for an LLC or C corporation formed online. Clerky for Delaware C corporation paperwork and founder stock. |
| Connecting your apps | Zapier, Make, n8n | Zapier for the widest set of apps. Make for a visual canvas. n8n for open-source workflows you can follow step by step. |
Can a solo founder raise money?
A solo founder can raise money, but the gap with teams is real and worth planning for. Carta's Solo Founders Report (December 2025) found that solo-led companies were 30% of startups founded in 2024 yet received 14.7% of the cash raised in priced equity rounds that year. ZeroCrew's view is that this gap makes a capital-light company the natural first step for many solo founders.
Agents lower the amount a solo founder needs to raise in the first place. ZeroCrew's job pages, like the one for AI assistants, mark which tools have a free plan, so a solo founder can build, sell, and support a product before talking to an investor. Revenue from real customers tends to be the strongest answer to any doubt about a company with one founder.
What does it take to be a solo founder?
Being a solo founder takes three things no tool supplies: the willingness to decide alone, a circle of people you can talk to, and the habit of checking your agents' work. ZeroCrew lists agents that help with each of these, but the founder owns them, and the founders who last tend to treat all three as part of the job.
- Deciding alone. You choose the price, the next feature, and when to stop. An AI assistant can lay out the options; the call stays yours.
- A circle of people. Mentors, peers, partners, and early customers who tell you the truth. They are the cocreators the research describes.
- Checking the work. Treat every agent like a capable new hire: review its first results closely, then give it more freedom as it earns trust.
Loneliness is one cost of going solo that research takes seriously. In a study of 377 small-business owner-managers in France, published in Burnout Research (2016), Claude Fernet and colleagues found that work stress led to burnout through a sense of loneliness at work, and that the effect was weaker for owners with a strong entrepreneurial orientation. ZeroCrew's advice follows: build your circle early, before the hard months arrive.
How does ZeroCrew help a solo founder?
ZeroCrew helps a solo founder compare the agents for each job in one place before trying any of them. The ZeroCrew directory sorts 181 AI agents and apps into 44 jobs across 11 roles, as of November 2026, and every job page shows the tools side by side, with what each one does and what solo founders say about it.
ZeroCrew's job pages rank each job's tools three ways. The automation page, for example, sorts tools by how many people search for them, by how many solo and early-stage founders say in public posts that they use them, and by how many of those founders' posts call the price good value, minus those that call it too much. A solo founder sees what peers really use, not what ads say.
ZeroCrew also works from inside your AI assistant. The MCP page shows the address to add ZeroCrew as a custom connector in Claude, Cursor, or ChatGPT, and your agent can then search the directory by job and read each tool's page. A solo founder can ask an agent which tools fit a job and get answers drawn from ZeroCrew's research.
ZeroCrew can set the agents up for you when you'd rather spend your time on customers. The AI agent setup picks agents for each job, connects them to the tools you already use, and keeps them current as new models come out, starting at $1,000 a month as of November 2026, after a free 30-minute call.
How do you start as a solo founder this week?
The fastest way to start as a solo founder is to choose one problem, list the jobs it needs, and hand the first repeatable job to an agent. ZeroCrew's guide on how to validate a startup idea covers the first step, and these steps take you from idea to a working first week:
- Pick one problem you care about. Choose something you'd work on for years. Check demand before you build.
- List the jobs. Write down every job the company needs this month: building, selling, answering customers, invoicing.
- Give one job to an agent. Open its page in the directory, compare the top two tools, and try both on real work.
- Name your cocreators. List two mentors or peers, one partner service, and one early customer you can call.
- Check, then widen. Review the agent's work each day for a week, then let it run more on its own.
ZeroCrew's essay Why zero employees explains the bigger idea behind going solo: work with people who choose to be there, and let agents do the rest. A solo founder who starts this week has more help available than any founder before, and ZeroCrew keeps the map of that help current, job by job.

Questions founders ask
Is it better to be a solo founder or have a cofounder?
Neither is always better. Greenberg and Mollick found solo-founded for-profit companies from Kickstarter survived longer than team-founded ones, while Howell and colleagues found solo founders matched cofounded peers when they built a circle of cocreators around them.
Is a solo founder the same as a solopreneur?
The terms overlap. A solo founder is the only founder of a company that may grow, hire, or raise money, while a solopreneur usually runs a one-person business and plans to keep it that way.
Do investors fund solo founders?
Investors do fund solo founders, but less often. Carta's Solo Founders Report (December 2025) found solo-led companies were 30% of startups founded in 2024 and received 14.7% of the cash raised in priced equity rounds that year.
How do solo founders deal with loneliness?
Solo founders who last tend to build a circle of mentors, peers, and early customers before the hard months arrive. Research on small-business owners links loneliness at work to burnout, so that circle is part of the job, not a luxury.
What should a solo founder hand to AI agents first?
Start with one job that repeats every week and is easy to check, like support replies, bookkeeping, or research summaries. Review the agent's work for a week, then give it more freedom as it earns trust.
Zero employees. Never build alone.
