Lewis is easily the best recruiter I've ever worked with. He isn’t just trying to fill roles; he genuinely focuses on finding the right fit. From the start, he took time to understand what I was looking for, helped refine my pitch, and tailored the search to my priorities. We stayed in close contact, and his insights always clarified my perspective. When it came time to decide, he helped me evaluate each offer with valuable context. He even reached out on my first day to wish me luck!

Lewis has been a huge help in building our Engineering organization and is the first recruiter I recommend startups work with. He stands out in three ways: 1/ Extremely easy to work with, adapting his pace and style to candidates, recruiters, and companies. 2/ Understands the type of candidate that thrives at Ramp, looking far beyond titles or logos. 3/ Builds deeper relationships than anyone I’ve met, placing several candidates at multiple great companies. Thanks to his skill and hard work, we’ve welcomed many outstanding engineers, several who’ve grown from ICs to key leaders. Thanks for everything, Lewis!

Highly recommend working with Lewis if you're looking to join a start-up in NYC! Lewis helped me a ton throughout my recent job hunt. From sitting down with me to understand my career goals (which he helped me clarify), to putting me in contact with great companies that met my criteria, and finally coaching me through the interview and negotiation processes. On top of being connected to great early stage start-ups I wouldn't have found on my own, Lewis really advised me on what was best for me. He didn't rush or pressure me to join any company. I would definitely work with Lewis again in the future.

Finding a new job (in this, and any market) can be a humbling, vulnerable and (hopefully) ultimately, a rewarding experience. In times like these, Lewis shines. He's positive, professional, enthusiastic, detail-oriented, smart, funny and puts you in your zone of excellence. He brings out the best - because he's one of the best. I was lucky enough to work with Lewis in finding my next role and consider him a friend. If you're reading this recommendation and thinking about what your next role could look like, get in touch!

Lewis is hands-down the best recruiter I’ve worked with. He takes the time to understand both candidates and the company, and only recommends people he truly believes are a strong match. Many are folks he’s worked with across multiple roles, showing the trust and long-term relationships he builds. He’s well-connected in the NYC startup world and knows what early-stage companies need. The candidate conversion rate from his pipeline has been the highest we’ve seen. Super responsive, professional, and a pleasure to work with!

Lewis was incredible throughout my search process. I appreciated how much thoughtfulness he brought to our interactions - he genuinely wanted to get to know me as an individual and invest in my professional success. He was a true advocate and made the process fun. I felt understood and supported in my journey, and I'm thrilled with my new team.

Lewis is absolutely amazing. He listened attentively to what I was looking for, helped me flesh out my thoughts on what my next role could look like, got me in touch with several really cool companies, and supported me through the entire interview+offer process. Perhaps most importantly, he did _not_ pressure me to accept an offer I was feeling iffy about -- instead, he encouraged me to continue thinking hard about what I wanted and where I could find it. He was always available when I needed him and perhaps most importantly, he's just a good guy to talk to and work with. Cannot recommend enough.

Lewis is a fantastic recruiter. He was responsive, well-connected, highly knowledgeable, and genuinely empathetic and receptive to my career goals. He also provided me with calm and well practiced guidance when the job hunt got tricky. I highly recommend folks work with him. I will certainly be reaching out to him for roles in the nyc startup scene in the future!

Lewis has been a huge help in building our Engineering organization. He is the first recruiter I recommend startups work with to build their engineering organizations. He stands out in three ways: 1/ He's extremely easy to work with, quickly adapting his pace, communication style, and mediums to the candidate, recruiter, and company he works with. 2/ He understands the type of candidate that will do well at Ramp very well, and looks far beyond the surface-level traits like titles, years of experience, or logos. 3/ He develops deeper relationships with candidates than anyone I've met, and has placed several of them at multiple great companies. Thanks to Lewis's skill and hard work, we've been fortunate to welcome many outstanding engineers to the team, several of whom have grown from strong ICs to key leaders. Thanks for everything you've done for us, Lewis!
Lewis stands out from nearly every recruiter I’ve worked with. He genuinely has your best interests at heart and takes the time to deeply understand what you’re looking for in your career. He only represents top-tier companies that he truly believes in, which means that no matter what you’re seeking, he’s likely to have an exciting opportunity that will interest you. Whether you’re actively searching for your next role or simply looking to build your network, Lewis is someone you need to know.
