  • The $1B Solo Founder: Build Your Startup With AI Agents

    The $1B Solo Founder: Build Your Startup With AI Agents

    Fintech House, Av. Duque de Loulé 12, 1050-093 Lisboa, Lisbon, PT

    Registration only via here.

    Learn how to build a team of AI agents that can start creating revenue and automating your growth — starting tomorrow.

    If you're building a startup in Portugal, don't miss this hands-on, in-person workshop.

    AI is changing the way startups are built. For the first time, founders can do things that were previously impossible: build “solo corns” — companies with the potential to become unicorns, built by a single founder.

    The founders who understand this new way of building will have a massive advantage.

    Instead of hiring a team of 40+ people to handle sales, marketing, operations, research, customer support and more, founders can now build teams of AI agents that work 24/7 and take on tasks that previously required entire teams of senior talent.

    Companies are already shipping products, launching GTM motions and experimenting faster than ever.

    In this workshop, we'll show early-stage founders how to do it themselves.

    You'll learn how to:

    • Build your own team of AI agents
    • Automate repetitive work across your startup
    • Use AI for sales, marketing, research and operations
    • Create AI-powered workflows that run 24/7
    • Move faster without immediately growing your headcount
    • Start building your startup like a solo corn

    Come with your startup, leave with an AI-powered team.

    ​*Evento em Português
    Já tens uma ideia. Como é que ela chega aos primeiros clientes?

    ​Ter um modelo de negócio no papel é uma coisa. Descobrir por onde entrar no mercado e com que canais é outra. Esta formação foca-se exatamente nesse passo: transformar suposições em hipóteses testáveis e escolher, com critério, onde investir o pouco tempo e o pouco dinheiro que existem no início.

    ​Ao longo de duas horas, vais trabalhar com metodologias consagradas no ecossistema empreendedor:

    1. Customer Development, para sair do edifício e falar com quem realmente decide;
    2. Formulação e teste de hipóteses, para substituir opiniões por aprendizagens medíveis;
    3. Bullseye Framework, para mapear os canais de tração possíveis e priorizar os três que valem a pena testar já.


    ​A sessão culmina com a construção ao vivo de uma landing page de validação e com a elaboração de um plano de ação Go-to-Market de uma página — ferramentas concretas que vais poder usar imediatamente para pôr o teu projeto à prova no mercado real.

    Para quem é:
    ​Fundadores e cofundadores de startups em fase inicial, empreendedores individuais, estudantes do ensino superior, profissionais curiosos pelas áreas da tecnologia e do empreendedorismo, e pequenos e médios empresários que queiram validar novos produtos, serviços ou modelos de negócio. Não é exigida experiência prévia.

    ​Esta é a Formação II do programa, mas é independente da primeira: não precisas de ter frequentado "Do Zero ao Um em Startup Building" para participar.

    O que vais levar contigo:

    1. ​Um plano de ação Go-to-Market de uma página para o teu projeto
    2. ​Uma landing page de validação estruturada e pronta a publicar
    3. ​Um mapa de canais de tração priorizado com o Bullseye Framework
    4. ​Acesso aos recursos gratuitos da plataforma Santander X (programa Explorer, cursos online certificados e desafios globais)
    5. ​Certificado digital de frequência e aproveitamento (mediante cumprimento dos critérios)


    ​Inscrição gratuita, vagas limitadas a 1000 participantes.
