Post-MBA IB Analyst - Recommendations for Bulge Bracket Recruiters?

I'm currently an Investment Banking Analyst at a lower middle market healthcare boutique (joined post-MBA). I've worked on sell-side, distressed, and growth capital mandates, including financial modeling and process execution across multiple deals.

I'm looking to make a lateral move to a bulge bracket or strong upper middle market platform where I can work on larger, more complex transactions and continue developing as a banker. I'm targeting Analyst to Associate level roles, with a preference for Associate where possible. 

Would appreciate any recommendations for reputable IB recruiters or headhunters who are active with bulge bracket lateral placements from boutiques. I've already reached out to a couple directly but would value additional names from people who have had good experiences.

Happy to provide more details via DM or email if helpful. Thanks in advance.
