Can I show my work experience in my startup without mentioning it is my own startup in UK?

Yes, you can list your startup experience on your resume without stating it is your own venture. Focus on your role, responsibilities, and achievements - highlight skills and contributions such as product development, marketing, or team leadership.

If you plan to work in the UK on a student visa, be aware that self-employment and business activities are generally not allowed unless you have applied for an Innovator Founder visa and are awaiting a decision. Including your experience is fine, but do not engage in business activities that violate your visa terms.
