Andrew Shapiro
Lead Product Manager
After over a year of unsuccessful solo job searching during a particularly challenging period, working with James was a game-changer. His coaching helped me transition from extended unemployment to receiving two competitive offers simultaneously for roles I was genuinely excited about.
James brought incredible energy to each session and coached me through every aspect of the process—from interview preparation to framing my experiences in ways that resonated with hiring managers. His guidance during salary negotiations was particularly valuable, helping me secure a 15% compensation increase that more than covered his coaching fee.
What sets James apart is his combination of strategic expertise and genuine investment in his clients' success. He worked tirelessly to help me achieve the outcomes I needed to move forward in my career. I highly recommend working with James—he truly transforms both your approach and your results. I'm excited to continue working with him as I grow in my new role.

I don't think I would have made it through my job search in one piece without James.
Before joining his community, I spent over a year applying on my own. It was exhausting and pretty demoralising. As a senior leader, I thought I had things fairly well-polished, but James provided invaluable insight that helped me stand out even more.
His resume reviews, mock interviews, and LinkedIn feedback were extremely helpful. He was also willing to review each one as many times as it took to get things right. On top of that, he supported me through a negotiation process that didn’t follow any standard playbook. It wasn’t a typical job offer (it was more like a business conversation) and he helped me think through it from multiple angles, not just as a candidate but as a peer.
What really made a difference, though, was the space he created. Being surrounded by others facing the same tough market helped me get out of my own head. That network kept me sane, gave me perspective, and helped rebuild my confidence at a time I really needed it.
If you’re a product professional or product leader navigating this market, James gets it. And he’s willing to provide you with real, thoughtful support.

I had the pleasure of spending time with James through both Product Sphere and in 1:1 settings and I cannot understate how valuable his insight is, especially when it comes to building your online profile on LinkedIn. James helped me understand the dynamics of content creation, what engages people and generates new followers, all while formulating a personal brand that has helped me unlock doors with new opportunities both personally and professionally. Every meeting with James has resulted in unearthing a new learning that is both practical and effective. When you combine James' depth of knowledge, personability and his practical-focused coaching style, you effectively have a tri-force of wisdom. I highly recommend James to Product people at any point in their career who are looking to go to the next level!

Senior Product Manager
When I first approached James, I had been job searching for five months with no clear strategy. At the same time, I’d left my role due to personal reasons, moved back home, and was navigating major life changes. I needed clarity, confidence, and direction — and that’s when I turned to James.
My application success rate was very low, but James quickly changed that. After rebuilding my CV together, I started getting noticed by major companies. He then gave me a clear, structured plan for improving my pitch and interview performance, which kept me focused and accountable.
Within three months, I landed an excellent new role with a highly competitive salary.
What I appreciated most was James’s mix of professionalism, warmth, and responsiveness. His coaching is practical, tailored, and genuinely transformative.
I’d highly recommend James to any PM looking to elevate their career. I’ll also continue working with him as I grow into the Product Leader I aspire to be.
Heather
Lead Product Manager
James is the steady anchor everyone needs when navigating challenging career transitions. For me, this support was invaluable when grappling with the incredibly tumultuous job market this year (2024). James’ coaching combines deep empathy and compassion with ultimate professionalism. He takes your development and goals as seriously as you do. During my job search and coaching from James, I noticed a 150% uplift in response to jobs I applied to directly. James also provided advice and tips on specific interview processes, as well as opportunities to do mock interviews, providing systematic and actionable feedback. In such a challenging job market, James kept me going with a personalised, down-to-earth, and shame-free approach. I genuinely believe I wouldn’t have secured my new role as quickly—or as confidently.
Philip
Head of Product
Thanks to James’s guidance, I’ve gained clarity on my career goals and improved how I communicate my value in interviews. It’s fundamentally shaped how I approach my career, and I couldn’t recommend James more highly.
Kate
Aspiring Product Manager
Working with James has been such a game-changer for me. He offers so much more than just career advice—whether it’s helping with my resume, setting clear goals, or prepping for interviews, everything he does is tailored based on individual needs. He’s not afraid to challenge my thinking either, which has really helped me see things more clearly and push past my own limits. What I love most is how much he genuinely cares and is always asking everybody ‘How he can I help?’. He truly wants to see people thrive and reach their full potential. James is down-to-earth, honest, and works with you at any stage of your career.
Joao
Product Manager
James was crucial to my success during my interview processes for a product manager role. He is very knowledgeable and patient and helped me navigate the challenging product sense interview. We did a mock interview that helped me get the confidence I needed. I highly recommend his services!
Lilian
Product Manager
I don’t think there is a better career investment I could have made than this! I have clarity on how to address so many unknowns with the help of the tools/strategies you’ve shared me. Your coaching style makes it easy for me to remember what we discussed because of the practicality of our discussions which helps me apply the lessons whenever challenges reappear in a new way. I also appreciate that you are such a great listener and you push me to figure things out (with your steady guidance). I appreciate that you are also one of my cheerleaders and probably the only person who fully understands the depths of my work, challenges, and wins. Looking forward to working with you forever!
Luke
Senior Product Manager
I received improved clarity in my job search and career development process and improved confidence in my resume.
Gianmarco
Product Manager
James was incredible in guiding me through the revamp of my CV and helping me practice interview questions. I finally received an offer in April '25, and I have received the same level of support through the offer negotiation, securing an 8% increase in compensation.
Lynsey
Principal Product Manager
I recommend investing in coaching sessions with James. Being able to see the job search 'from above', rather than being trapped inside it has already made a difference to my levels of hope and confidence.
Rene Muhire
Senior Product Manager
I recently received a job offer, and I believe the work I did with James significantly contributed to that success. The stories I wrote during our time together proved to be invaluable, and the experience encouraged me to be more thoughtful about the roles I pursue in the future. I’m incredibly grateful for his support throughout the process.
Luke Whitesides
James helped me navigate through an increasingly difficult job market and job search process. He is uniquely capable at separating fact from fiction amidst a dynamic and constantly evolving career field. Working with him provided the clarity I needed and helped me improve my interviewing, storytelling, and positioning skills to land a role I am stoked on! Would highly recommend to anyone in the product management field who feel like they need a boost!
Fabz
Senior SaaS Product Manager
From Product Manager to Product Leader. James has everything we need to know in order to learn, grow and apply the right skills to land our dream roles.
I went from a complete stranger to James content, to subscribing to all latest PM insights and apply his 20yrs of industry knowledge to my own professional development and career growth.
He has helped me apply and repackage myself as a Senior Product Manager landing more interviews at the companies I used to get auto rejected from.
Joe Miller
Product Manager, SNG
I joined the Product Sphere community because my CV wasn't converting into interviews, and when I did reach the interview stage, I found myself jumping around too much in my responses. James was amazing at helping me rework my CV and prepare for interviews through mock scenarios. His guidance on optimising my LinkedIn profile and mastering the STAR method was incredibly valuable and helped me land my next Product role. I highly recommend James as both a coach and mentor!
Victoria Pace
You are deeply knowledgeable and great at conveying patterns, themes and actionable insights. I have been actively looking for work for the last eight months, although only out of “stealth mode” for the last two months, and have learnt a lot.
Adam Schweig
Product Manager, Service at Comcast (starting in Sept 2025)
I had the opportunity to learn from James through the one-month PM Career Boost program at Kadima Careers, which included group coaching calls, a self-led LinkedIn optimization course, and a one-on-one session where I could ask James anything I needed related to my job search.
Joining the program was one of the best moves I made. It was affordable, focused, and packed with practical insights. James and the team brought sharp product thinking and a clear, practical approach to resumes, interviews, and overall strategy.
They were thoughtful, direct, and honest, which helped me cut through the noise and focus on what I needed to. I left the program with stronger product stories, sharper positioning, and a clearer path forward.
A few weeks after wrapping up the program I landed a remote contract PM role that feels like a solid next step. I’d definitely recommend the program to other product-focused professionals, and I’d consider working with James again as I continue to grow in my career.

Navigating the product management job market felt daunting until I found Product Sphere and James Gunaca. James crafted a supportive environment with group sessions, community tools, and meet-ups that connected me with fellow job seekers. Crucially, his personalized resume reviews and mock interviews gave me the edge I needed. Product Sphere equipped me with the confidence and refined skills to ace my interviews and secure my new role. It's truly a game-changer for product professionals looking to elevate their job search.
Frank Barczak
Working with James was a game-changer. I came into our session with a strong background but a lackluster resume. James helped me frame my experience clearly, highlight the right achievements, and target my job search effectively. Because of his guidance I submitted resumes and got A LOT more interviews.
Andy
Lead Product Manager, Bupa
I want to say a big thank you to James for all his coaching and support. His help in getting me through the early competency rounds was absolutely invaluable. I’ve recently accepted a new role at Bupa. I came a very close second to an internal candidate for the role that James helped me prepare for, but I stayed in touch with the team and have now secured a Lead Product Manager position within their Clinics area.
Krishna
Senior Product Manager
James has a remarkable ability to guide you in mapping your experience to the job requirements and presenting it with the right narrative and at the right level. He doesn’t just help with interviews — he teaches you how to pitch yourself confidently, structure your story, and communicate your value effectively. James is approachable, friendly, and understands the ask of the hour perfectly. I have been part of James’ product community for 1 year, and he is a great product coach. His guidance makes a real difference in building confidence and clarity in any high-stakes situation.
