  The dissipation of severe acute respiratory syndrome coronavirus 2
(SARS-CoV-2) has already taken on pandemic proportions, affecting over 100
countries in a couple of weeks. The evolution of the disease and its economic
impact is highly uncertain, which brings challenges for newly created software
companies. Software startups are companies that create innovative software
products and services in a dynamic and fast-growing market. Agile Software
Methods aims to enable startups in responding to uncertainty caused by
Covid-19. This paper investigates the impact of Covid-19 in a real software
startup context to understand how they have reacted against uncertainties
caused by Covid-19. As a research methodology, action research within Di2Win, a
Brazilian software startup, has been applied. The study was carried out
throughout six sprints, during the quarantine. Practices employed to mitigate
threats while simultaneously allowing teams to remain open to opportunities and
challenges are detailed. This paper shares lessons learned that could help
agile software startups improve their way of work in an uncertain environment
caused by the Covid-19 pandemic.
