the top 10 most successful businesses to start in 2026

Looking for the top 10 most successful businesses to start? Discover practical, profitable ideas you can build anywhere.

Across Europe and beyond, the most successful businesses to start rely on models that are digital-first and practical to run. They can often begin as side projects – built in spare hours, tested in small steps, and scaled once there is clear demand.

This list brings together ten of the most successful businesses to start in 2026. Each idea has been selected using three criteria: it can begin small and grow gradually; it solves a real, recurring problem; and it has been shown to work in real business settings.

Along the way, you will also find short perspectives drawn from Winning Friends, a podcast featuring global founders reflecting on how they built their careers and companies – and, just as importantly, how their thinking evolved along the way.

1. Specialised consulting and fractional roles

Consulting remains one of the fastest routes from expertise to income. Today’s demand is for specialists: go-to-market strategists for SaaS, operations consultants for e-commerce, finance partners for small businesses, or HR leaders for growing teams.

Fractional roles – such as part-time CMOs or CFOs – are also becoming more common as companies look for senior experience without a full-time hire.

Why it works

• Low startup costs and fast cash flow
• High demand across industries
• Easy to start as a side project

How to start

• Define one problem you solve and one type of client you serve.
• Package your offer into outcomes (audit, sprint, ongoing support).
• Build two or three strong case examples before investing heavily in branding.

In practice
In his Winning Friends episode, Jeff Pan, CEO of Belli, describes how his early years in consulting led to his first major client in the air-cargo industry – long before he was building software. Working inside real operational problems gave him credibility and access that later shaped his career. A useful reminder that consulting can be a superb way to discover which challenges are worth turning into products.

2. Niche digital marketing micro-agencies

Marketing agencies are nothing new, but in practice, many of the most resilient ones today are highly specialised. Rather than trying to serve everyone, they focus on one sector and one core service – for example, LinkedIn lead generation for B2B companies, SEO for local services, or paid ads for e-commerce brands.

Why it works

• Recurring revenue through retainers
• Clients can be served remotely across markets
• Clear path from solo operator to small agency

How to start

• Choose a niche you understand and can speak of credibly.
• Offer a low-risk entry product such as an audit or strategy session.
• Build simple reporting from day one so clients can see what is changing.

As competition for attention intensifies, demand for skilled content production continues to grow. Video editors, podcast producers, newsletter writers, and content strategists can build profitable service businesses – often fully remote.

Why it works

• Demand exists across sectors, not only in consumer brands
• Straightforward to package into repeatable deliverables
• Often leads naturally into consulting or products

How to start

• Package services into clear bundles instead of selling tasks.
• Build a repeatable workflow from intake to publishing.
• Focus on one format first: video, audio, or written content.

In practice
Some of the strongest business ideas can emerge from careful listening. Avery Schrader, CEO and co-founder of Modash, has said that his company did not begin as a fully formed product idea but grew out of conversations with other founders and marketers. Those early interviews revealed a common frustration: how difficult it was to work with creators in a structured way.

4. Digital products: templates, toolkits and playbooks

Digital products are one of the most scalable models available to a small team or solo operator. Templates for marketing, operations, finance, or HR can save customers time and prevent mistakes – which makes them valuable if they solve a specific, recurring pain point.

Why it works

• High margins after creation
• No inventory, shipping, or complex operations
• Can be sold internationally from day one

How to start

• Identify a problem you already help people with repeatedly.
• Launch a simple version and validate it before adding features.
• Treat your product like software: update it based on user feedback.

In practice
John Rush, entrepreneur and automation specialist who runs multiple profitable businesses with minimal teams, often describes testing ideas publicly before committing to them – building interest and audience first, product second. That approach is particularly relevant for digital products, where demand validation matters as much as polish.

5. Online courses and cohort-based education

Learning has moved decisively online, but the strongest education businesses focus on outcomes rather than content volume. Cohort-based courses, where participants learn together over a defined period, have become especially popular for professional skills.

Why it works

• Strong demand for upskilling and career pivots
• Builds authority alongside revenue
• Can expand into community, consulting, or products

How to start

• Run the course live before recording anything.
• Design around transformation, not information.
• Add accountability and community to improve completion rates.

In practice
Pepe Villatoro, co-founder of the Fuckup Nights movement, built his business by paying attention to something most people prefer to avoid: the fear of failure. By turning that shared experience into events, training, and community, he shows how powerful it can be to start from an honest observation of what people struggle with.

Print-on-demand lets you build a product brand without managing inventory. From apparel to homeware and accessories, success depends more on positioning and design than on the mechanics of fulfilment.

Why it works

• Low upfront risk
• No warehousing or fulfilment operations
• Easy to test ideas quickly

How to start

• Build around a niche identity rather than generic slogans.
• Launch with a small, focused collection.
• Collect emails early to reduce reliance on paid advertising.

7. Niche e-commerce with lean fulfilment

While print-on-demand focuses on made-to-order products, niche e-commerce is about owning or curating a physical range – often with limited stock, careful sourcing, and strong positioning.

Rather than competing on mass-market products, many businesses do well by serving a narrow audience: sustainable home goods, specialist sports equipment, curated lifestyle products, or hard-to-find consumables.

Why it works

• Large market, but room for specialist operators
• Repeat purchase potential
• Opportunity to build brand trust over time

How to start

• Choose products that encourage loyalty and repeat buying.
• Compete on curation and service, not price alone.
• Keep operations lean in the early stages.

While headlines focus on major AI breakthroughs, the biggest potential in this space hides on a much more practical level. Helping companies automate everyday workflows – from customer support to reporting – can create immediate value without building complex technology.

Why it works

• Strong demand across sectors
• Clear, measurable ROI for clients
• Can be built on existing tools, not from scratch

How to start

• Focus on one process you can improve significantly.
• Sell time saved and errors reduced, not technology.
• Document solutions so they can be reused across clients.

In practice
In Winning Friends, John Rush walks through how one of his products began with a repeated complaint online about web pages not being indexed. He built a minimal waitlist-style flow in minutes to test demand, delivered the solution manually behind the scenes, and only then automated it once people clearly wanted to pay for the outcome. He marketed it by replying where the problem was already being discussed. The takeaway for anyone offering automation as a service: start by replacing one concrete piece of manual work, prove the demand, and only then scale with systems.

9. Cybersecurity and compliance support for SMEs

As cyber threats increase and compliance requirements tighten, small and mid-sized companies are under pressure to improve security without hiring full internal teams.

There is also a wider opportunity emerging at the intersection of cybersecurity, fraud prevention, and trust – an area where better tools, verification layers, and safer processes are becoming increasingly valuable.

Why it works

• Long-term relevance
• High trust and retention
• Rising regulatory and reputational stakes

How to start

• Begin with assessments, training, and baseline policies.
• Package services into a clear onboarding programme.
• Partner with IT providers for referrals.

In practice
In her Winning Friends episode, Cecilie Fjellhøy, The Tinder Swindler survivor and anti-fraud advocate, discusses how sophisticated scams have become and how often responses remain reactive rather than preventative. It is a useful prompt for anyone exploring security, verification, or trust-based services: there is growing space for businesses that focus not only on detection, but on reducing risk before damage is done.

10. Bookkeeping and financial operations services

Every business needs financial clarity, yet many struggle to maintain it themselves. Remote bookkeeping, management reporting, and finance operations support are often chosen for their stability and long-term client relationships.

Why it works

• Demand exists in every economic climate
• Easy to standardise
• Clients rarely switch providers once trust is established

How to start

• Offer one simple monthly package at first.
• Build around one software stack.
• Move gradually from execution to advisory services.

If you are stuck at the ideation stage, try this short exercise. It is designed to move you from “What could I do?” to “What do people already need?”. The structure draws on well-established thinking in entrepreneurship and product development. From the principles of validated learning and small experiments popularised in The Lean Startup, to customer development methods that emphasise testing assumptions through real conversations, as outlined by Steve Blank in The Four Steps to the Epiphany. It also reflects the idea of building from your unfair advantages, a concept explored by Paul Graham in his essay Do Things That Don’t Scale.

• Industries you understand better than most people
• Skills people already ask you for
• Problems you have solved repeatedly

Choose a problem that is:

• frequent,
• costly in time, money, or risk, and
• irritating enough that people would pay to remove it.

Match the problem to the simplest model:

• Service for quick cash flow (consulting, content, bookkeeping)
• Product for scalability (templates, toolkits)
• Education for authority (courses, cohorts)
• Commerce for brand differentiation (print-on-demand, niche e-commerce)

Decide what you will test in the next two weeks:

• one paid audit;
• one package offer;
• one landing page with pre-orders;
• one cohort pilot with five participants.

In Winning Friends, Pepe Villatoro reflects on “designing life” – moving away from chasing imaginary future end states and towards building work that aligns with values in the present. It is a useful lens when choosing among the top 10 most successful businesses to start: the business should be viable in the market and viable in your life. If an idea forces you into a way of working you already know you do not want, the cost tends to surface later.

The top 10 most successful businesses to start are not defined by trends or technology alone. They succeed because they are built on clear value, disciplined experimentation, and structures that can grow without unnecessary complexity.

Whether you begin with a side project, a service offer, or a small digital product, the same principle applies: start small, test quickly, and build something people genuinely need.
