As discussed in The Accelerator Conundrum Series, starting a company alone presents unique challenges for entrepreneurs. Solo founders often manage product development, customer acquisition, marketing, operations, fundraising, and strategic decision-making simultaneously. It further highlights why access to mentorship and external support can be particularly valuable for founders building without a co-founding team. 

Historically, many accelerator programs favored startups with multiple founders. Investors often believed founding teams were less risky because responsibilities could be distributed and different skill sets combined. As entrepreneurship has evolved, more accelerators have recognized that successful companies can be built by solo entrepreneurs.

For founders in Lisbon, this shift creates significant opportunities. The city’s startup ecosystem has expanded rapidly, attracting accelerators, incubators, investors, and innovation programs that increasingly support individual entrepreneurs.

This article explores the best accelerators for solo founders in Lisbon and examines which programs provide the flexibility, mentorship, and support structures most valuable to entrepreneurs building companies on their own.

The Rise of Solo Entrepreneurs in the Age of AI

Artificial intelligence is fundamentally changing how startups are built. Tasks that once required entire teams—including software development, graphic design, marketing, customer support, data analysis, and content creation—can now be completed by a single founder using AI-powered tools.

As a result, the barriers to launching a company have fallen dramatically. Entrepreneurs can build prototypes faster, automate repetitive workflows, generate marketing materials, analyze customer feedback, and manage day-to-day operations with significantly fewer resources than was possible just a few years ago. This allows founders to validate business ideas and generate early revenue before expanding their teams.

The rise of AI has also shifted investor and accelerator perspectives. While founding teams continue to offer advantages in many situations, a growing number of successful AI-enabled startups demonstrate that a highly capable solo entrepreneur can achieve substantial traction independently. Increasingly, the differentiator is not team size, but the founder’s ability to leverage technology effectively, understand customer needs, and execute quickly.

For solo entrepreneurs in startup ecosystems such as Lisbon, this creates new opportunities. Rather than assembling a co-founding team simply to cover operational gaps, founders can use AI to extend their capabilities while relying on experienced mentors, industry networks, and accelerator programs for strategic guidance. As AI continues to improve productivity, accelerators that recognize and actively support solo founders are becoming increasingly valuable.

Why Solo Founders Need Accelerators

Building a startup alone presents unique challenges. While solo founders benefit from complete control over decision-making, they also face limitations that teams often avoid.

Common challenges include:

Limited Bandwidth: One person must handle every aspect of the business, from customer discovery to operations.

Smaller Professional Networks: Founding teams often bring multiple networks into a company. Solo entrepreneurs may need external support to build relationships with advisors, customers, and investors.

Fewer Accountability Systems: Without co-founders, maintaining momentum and strategic focus can become more difficult.

Increased Fundraising Challenges: Some investors still prefer startups with multiple founders, making mentorship and credibility especially valuable.

Accelerators can help bridge these gaps by providing structured guidance, educational resources, peer communities, and investor introductions.

Why 1Mby1M is the Best Accelerator for Solo Entrepreneurs in Lisbon

Among Lisbon-accessible accelerator programs, 1Mby1M is particularly well suited for solo founders. Many accelerator programs technically accept individual founders but were originally designed around team-based startup models. 1Mby1M takes a different approach by supporting entrepreneurs regardless of team size.

Several characteristics make it especially attractive.

Explicitly Solo-Founder Friendly

The program welcomes entrepreneurs who are still building teams or who choose to remain solo during the early stages of company development. This removes pressure to recruit co-founders simply to satisfy accelerator application requirements.

Long-Term Mentorship

Many accelerators operate for eight to twelve weeks. Solo founders often need support over much longer periods because they are carrying all responsibilities themselves. The renewable one-year structure provides guidance across multiple stages of growth.

100% Virtual Participation

Running a startup alone often requires careful time management. A fully virtual structure allows founders to participate without relocating or interrupting day-to-day operations.

Focus on Revenue and Validation

Solo founders frequently benefit from customer traction before pursuing investment. 1Mby1M emphasizes validation, customer acquisition, and business fundamentals rather than immediate fundraising.

Personalized Investor Introductions

When companies become investment-ready, founders receive targeted introductions rather than relying solely on Demo Day presentations.

Equity-Free Participation

Retaining ownership is particularly valuable for solo entrepreneurs because there are already fewer stakeholders sharing responsibility. 

For solo founders seeking flexibility, mentorship, and ownership retention, these characteristics create a compelling combination.

How 1Mby1M Compares

While all programs in this comparison accept solo founders, their support structures vary considerably. Many accelerators were originally designed around venture-backed startup models and short cohort periods. Others focus heavily on local ecosystem integration or specific industries.

1Mby1M distinguishes itself through:

• Full virtual accessibility
• Equity-free participation
• Long-term mentorship
• Solo-founder friendliness

Organizations such as Startup Lisboa, Beta-i, BGI, Build Up Labs, Unicorn Factory Lisboa, Startupbootcamp, Techstars, Bright Pixel, Faber Ventures, and Incubou all offer opportunities for individual entrepreneurs.

However, the combination of equity-free participation, long-term mentorship, fully virtual access, and personalized support makes 1Mby1M particularly attractive for solo founders seeking sustainable growth.

By selecting the right accelerator, solo entrepreneurs can gain access to the guidance, accountability, and networks needed to transform promising ideas into successful businesses.
