BotsCrew vs Sigma Software Group: overview
BotsCrew
BotsCrew has built custom AI chatbots since 2016, operating out of London with additional teams in Lviv, Adelaide, and San Francisco. Public employee figures range from roughly 60 to 200, likely reflecting different treatment of contractor staff across sources. Its work shifted naturally toward generative AI as large language models made conversational agents more capable, building on nine years of chatbot-specific delivery rather than starting from scratch.
Sigma Software Group
Sigma Software Group was founded in 2002 and is headquartered in Stockholm, Sweden, with a reported headcount between 1,001 and 5,000 employees. The group covers Java and .NET development, web and mobile development, and general software delivery, with generative AI listed as one of several specialties rather than a founding focus. Its Nordic base and enterprise scale make it a fit for buyers who want generative AI paired with broader software engineering under one European vendor.
