Businesses you can run over the internet: software and tools, marketing services, digital content, consulting and advisory work. Startup costs are usually lower than a physical unit — often a computer, a domain and a few subscriptions. Every entry states its costs, margins, step-by-step launch plan, risks, and a calculator you fill with your own figures.
A cheap start has a price of its own. A low barrier to entry means anyone can be doing the same thing next month. The real cost here is not the tooling but customer acquisition — months of writing, outreach and building a name before demand becomes steady. If you need revenue within weeks and dislike selling yourself, hands-on services will suit you better.

After the wedding, couples chase guests' photos around group chats. A shared camera with a delayed reveal collects them by itself — and adds suspense.

People forget to water plants and kill them. An app tracks their care — but reminders alone will not sustain a subscription, deeper value does.

Service work based on your own skills starts cheapest — consulting, copywriting, campaign management, editing. No stock, no development. You pay for it in time instead: income grows only with hours worked, until you start hiring or turning the service into a product.
Yes, for most ideas here, because you set your own schedule. Expect clients to want replies during working hours, though. Models built on longer deadlines and asynchronous communication work far better than ones that need you on the phone the same afternoon.
