Logo is not everything about a brand, but certainly it will be most of the potential audiences' first impression and introduction, a starting point of an audience's journey, to the brand, especially for new brands like Tech Start-ups. I have chosen Basic Sans as the primary typeface, as it consists of a wide range of weights, which can be applied according to the use case, and I think simplicity of a technology's brand is very vital for reaching customers, at least the primary identity like logo, as if the design is somehow 'too technological', it will stop normal masses from interesting and exploring the brand.
