Is it too late to get a boutique IB internship for Summer 2023? (sophomore)

Hi,

I'm a sophomore at a non-target but have a pretty good resume under my belt for what it's worth. I'm trying to keep pace with 2024 recruiting but have been unable to get an internship for this upcoming summer and was told recently by an alumni who referred me that securing one, preferably at a boutique, was crucial.

I'm wondering if anyone has any insight on how to approach cold-emailing people at boutiques whether it's the bankers or whoever is in charge of HR, and on how to view the current timeline I have given it's already February.

Thanks for any help.
