Blumenau é referência nacional na produção de softwares, graças, entre outros fatores, ao curso de Ciência da Computação da FURB, que atua intensamente em pesquisa e desenvolvimento, através de projetos que desenvolvem atividades como capacitação de recursos humanos, transferência tecnológica e incubação de novas empresas.

O Colégio Sinodal Doutor Blumenau é uma Escola Comunitária. Pertence à Associação Hospitalar e Educacional de Pomerode, que é integrada pelas comunidades associadas à Igreja Evangélica de Confissão Luterana no Brasil (IECLB), estabelecidas no município de Pomerode. A filosofia norteadora de todo o trabalho é fundamentada no Evangelho de Jesus Cristo, testemunhado na Bíblia e nos demais escritos confessionais.
