Completed 3 Months of Probation at an IT Startup...

I completed the 3-month probationary period at an IT startup...

I completed the 3-month probationary period at an IT startup and then left the company,

Among the tasks I did there (writing business proposals, preparing IR materials, administrative work, etc.), there are tasks that will be helpful for the company (small and medium-sized enterprises) I'm applying to,

I'm worried that they won't view it favorably because I worked at the startup for such a short time,,

What do you think? Should I not include it in my work experience?

I would appreciate your advice (__)
