Mason Alexander is an outstanding partner for any high-growth startup. They’ve played a key role in helping us recruit and hire incredible talent, working alongside us as a true extension of our team.
Kushal Negi
CTO & Co-Founder Glimpse AI
Mason Alexander is a world-class recruitment firm. They have been an incredible partner to me and my companies over the years and always exceed expectations. They understand the scope of every mandate and have a unique ability to attract the most exceptional candidates. I rarely give recommendations, but I would encourage anyone to work with Andrew and his team.
Linda Yaccarino
CEO, eMed Former CEO, X
Andrew was extremely helpful throughout the recruiting process; he guided me through all rounds of the process and handled all of the admin overhead. Transparently communicated steps clearly, gave great feedback, and even helped with offer negotiation. He also clearly cares about building long term relationships with candidates over transactional hiring. Would definitely reach out to him again when if I’m ever back on the job market.
Alex Xu
Member of Technical Staff, xAI
Andrew is genuinely aligned with the candidate’s goals and is very knowledgeable on the firms he works with. He has been a helpful resource not only with those firms but also others I was in the process with. Working with Mason Alexander has been a great experience and a highly recommend it to anyone looking to chase their next opportunity.
David Ning
Member of Technical Staff, xAI
Andrew recruited me to xAI. He was very easy to talk to and was very clear about the necessary steps to get the final offer. He also let me know a lot about working at xAI before joining, so it was easy for me to know what to look for. The team I ended up joining was great; I would definitely recommend Mason Alexander to other engineers.

I'm so grateful I could work with Alex while I was searching for a new role. She made the entire interview process feel fast and smooth, and I always felt like she was an ally of mine and advocating for my best interests. Thanks to Alex, I've landed a true dream role and I couldn't be happier. I'm beyond appreciative of her and the impact she's had on my career!
Nicole Balsamo
Head of Marketing, Ouset
Alex got me hired at my dream company! Working with Alex was a pleasure -- she's friendly, conversational, and has a high EQ that sets her apart from traditional recruiters. She was quick to check in between interviews, was a seamless liaison between me and the hiring team, and stayed engaged even past the offer. One of the best experiences I've had with a recruiter, I highly recommend working with Alex!
Faraz Milani
Product Manager
I had a great experience working with Andrew and his team. I had full confidence that he had my best interests in mind. I never had any pressure to make a decision and the whole process was very transparent and respectful. I would strongly recommend Mason Alexander.
Austin Yao
Member of Technical Staff, Factory
My experience with Mason Alexander has been, hands down, the best recruitment — and overall client — experience I've ever had. Communication was excellent and seamless: quick follow-ups, fast turnarounds, and thoughtful conversations about not just any role, but the right role for me. They took the time to truly understand my interests, background, and career aspirations, and it showed — I was introduced to cutting-edge AI opportunities I wouldn't have found elsewhere. It was clear this was never about filling a position as fast as possible, but about finding work I'd genuinely be excited by. I'm especially grateful to have worked with Andrew, who was a true advocate and driving force throughout the process. Since then, I've recommended Mason Alexander to several close friends, and they've all shared the same outstanding experience.
Charles Rockhead
Software Engineer, OpenRouter
It was a great experience working with Andrew. He made the entire interview process clear and straightforward, and checked in regularly, even on weekends, to ensure there were no misunderstandings. He genuinely took the time to understand my situation and did his best to accommodate my needs.
I would absolutely recommend Mason Alexander to other engineers exploring startup opportunities, and I would especially recommend working with Andrew because he is thoughtful, sharp, and incredibly kind.

Software Engineer, Uno
