'Tech' is a colloquial short form of 'die Technologie' (technology) or 'die Technik' (technology/engineering). The feminine article 'die' comes from these longer words.
Er interessiert sich sehr für die neuesten Entwicklungen in der Tech.

This word belongs to colloquial language and workplace jargon. In formal or academic texts, you would more likely write 'Technologiebranche' (technology industry) or 'Technologiesektor' (technology sector).

'Tech' is very often used as the first part of compound nouns to create a connection to the technology industry. Examples include 'Tech-Unternehmen' (tech company), 'Tech-Startup' (tech startup), or 'Tech-Gigant' (tech giant).

technology / technique
'die Technik' and 'die Tech' look similar, but they are used differently. 'die Technik' is a normal German word for technical processes, devices, or systems. It can also refer to the technical equipment in a house, car, or system. 'die Tech' is a colloquial short form and mainly means the technology industry, that is, companies and people in this economic sector. Learners may confuse the words because both have to do with technology. If you are talking about devices, machines, or a technical solution, use 'Technik'. If you are talking about the industry, 'Tech' fits better, especially in modern language.
