Tech business ideas

Small tech businesses one skilled person can start and run.

By Solopreneur.co EditorsUpdated 4 min readLast reviewed 21 Oct 2026

Tech businesses can scale without staff because software and digital products cost little to deliver again. Solo founders win by picking a narrow niche and solving one painful problem, not building a broad platform.

1. Web design for local businesses

Build and maintain simple, fast websites for trades, clinics, restaurants and other local firms.

Startup cost
$100–$800
First sale
3-8 weeks
Skills
Site builders or code, basic copy, sales calls

How to start

  1. Pick one builder (WordPress, Webflow, Framer or a hosted builder) and one niche.
  2. Rebuild 2 real local sites as free concepts to show before/after.
  3. Sell a fixed-price build plus a monthly care plan (hosting, updates, small edits).
  4. Collect a testimonial and a case study from each finished project.

Watch out: Recurring care plans are where the stable income is; one-off builds are lumpy.

2. Digital products (templates, planners, presets)

Sell downloadable templates (Notion, spreadsheets, Canva), checklists or presets.

Startup cost
$0–$300
First sale
2-8 weeks
Skills
Design, a specific expertise, product thinking

How to start

  1. Solve one painful, specific job (e.g. 'freelance invoice tracker for photographers').
  2. Ship a v1 in a weekend and sell it at a low price to the first 20 buyers.
  3. Collect feedback and turn requests into v2 or a bundle.
  4. Grow with content that shows the product being used.

Watch out: Easy to copy; your audience and updates are the moat.

3. Online course or cohort

Package a skill into a self-paced course or a live cohort.

Startup cost
$100–$2,000
First sale
2-4 months

How to start

  1. Run the material as a live workshop first; pre-sell seats before recording anything.
  2. Turn the recordings and questions into a structured course.
  3. Collect outcomes from the first cohort to use as (real) proof.
  4. Add a community or office hours to justify a higher price.

Watch out: Without an audience, courses sell slowly; build an email list first.

4. AI automation consultant

Automate repetitive work (lead intake, follow-ups, reporting) for small businesses with tools like Zapier, Make or AI assistants.

Startup cost
$0–$500
First sale
2-6 weeks
Skills

  1. Automate 3 workflows in your own life or job and document them.

Watch out: Clients' data and privacy: get written approval before connecting their accounts.

5. Micro-SaaS / small software product

Build a small paid tool for a narrow audience (e.g. a scheduling add-on for a specific platform).

Startup cost
$50–$2,000
First sale
3-12 months
Skills
Coding or no-code building, product sense

How to start

  1. Find a recurring complaint in a niche community or app marketplace reviews.

  4. Grow through the marketplace or community where the problem lives.

Watch out: Platform dependence: if you build on someone's marketplace, their rule changes can hit you.

Offer rapid prototypes to inventors, product designers and small manufacturers.

Startup cost
$1,000–$8,000

Publish genuinely useful reviews and guides and earn commissions when readers buy.

Startup cost

How to choose between these ideas

Score each idea 1–5 on four questions and start the one with the highest total:

  1. Can you get paid in 30 days? Services usually beat products here.
  2. Do you already have the skill? Learning and selling at once doubles the risk.
  3. Do you know where buyers gather? A community, marketplace, local street or your old industry.
  4. Could it run on 5–10 hours a week? Most people start alongside a job.

Then validate before spending money: see how to test a business idea.
