About Pim Jitnavasathien

Co-Founder and CPO at Lumeir

I've spent my career as the only designer in the room, building design practices from scratch at startups where nothing was defined. Today I'm a cofounder and CPO, and I've learned, often the hard way, what it takes to grow as a designer, a leader, and a builder.

I know what it feels like to have an idea and not know where to start, to hit a milestone and still feel lost, or to want honest feedback and not know who to ask.

My goal isn't to tell you what to do. It's to help you build the confidence to make better decisions yourself.

Founders and makers: if you're overwhelmed or unsure what's next, we'll cut through the noise, turn a fuzzy idea into a clear first step, and connect what your users need to what your business needs, so you build the right thing, not just more things.

Designers: we'll sharpen how you communicate your work, handle tricky stakeholders, and pressure-test whether your design solves a real need.

I can also help you bring research into your process and shape product roadmaps so your work creates real impact, not just deliverables.

Bring one messy problem, whether it's a half-formed idea, a stalled project, or a design you can't quite trust, and we'll leave with a clear next step.

You don't have to figure this out alone. That's what I'm here for.

Sessions with Pim Jitnavasathien

• Startup & Business Ideas: Let's Think It Through (30 min): Building something of your own can be exciting, overwhelming, and sometimes a little lonely. Whether you're exploring a business idea, developing a product, or navigating startup challenges, sometimes you just need someone to bounce ideas off of. I've spent over six years working with startups as a founding product designer and experienced the ups and downs of building my own. I've learned that moving forward isn't always about having the right answers. Sometimes, it's about asking better questions and seeing things differently. What we can explore together: - Ideas & Direction: Untangling thoughts and figuring out what's next. - Product Strategy: MVPs, validation, user needs, and priorities. - Business Positioning: Clarifying your audience, value, and messaging. - Founder Challenges: Navigating uncertainty and difficult decisions. - Soundboarding: Challenging assumptions and exploring perspectives. What to expect: A collaborative conversation, not a lecture. I'll ask questions, share experiences, and help you find clarity. No polished pitch or business plan needed. Bring what's on your mind, and let's think it through! Note: Free sessions are for brainstorming and general guidance. Deeper or ongoing business support can be discussed separately.
• Surviving as a Sole Designer (30 min): Being a sole designer often means figuring things out without a clear roadmap. In this session, I’ll share practical lessons from my experience designing products from the ground up, working with stakeholders and engineers, advocating for users, and making confident decisions in ambiguous environments. This session is for designers who feel unsure, overwhelmed, or alone in their role and want guidance on how to grow, communicate better, and survive the chaos with more confidence. Optional Agenda: 1. Sole designer reality check 2. Finding direction in ambiguity 3. Working with stakeholders & engineers 4. Prioritizing when everything feels important 5. Building confidence without a design team
• Feeling Lost as a Designer? (30 min): Growing as a designer can feel confusing when you are no longer just learning tools, but trying to think more strategically, make stronger decisions, and become more independent in your work. It can be hard to know what “better” really means, how to think bigger, or how to move toward a more senior level when the path feels unclear. This mentorship session is for entry-level to intermediate designers who feel stuck, unsure, or overwhelmed in their growth. We can talk through your work struggles, portfolio direction, design process, communication challenges, stakeholder situations, or what it means to grow beyond execution into more strategic product thinking. The goal is to help you feel more grounded, understand where you might be getting stuck, and find practical ways to become a more confident, thoughtful, and independent designer.
• Design Critique (30 min): Design Critique Looking for constructive feedback on a personal project, portfolio piece, or product design? In this session, we’ll walk through your design together and identify what is working, what feels unclear, and where the experience can be improved. I’ll provide actionable feedback on visual design, UX flow, information hierarchy, interaction clarity, and overall usability. We can also look at whether your flow matches your users’ mental model, helping you spot moments where users may feel confused, slowed down, or unsure of what to do next. The goal is to give you clear, practical next steps so you can improve your design with more confidence and intention. Session 1: Initial Design Critique We’ll review your design together to identify what’s working, what feels unclear, and what changes can make the experience stronger and more aligned with your users’ mental model. Session 2: Follow-up Design Review We’ll look at how your design has improved since the first critique, refine anything that still feels unresolved, and define the next steps to make the experience even stronger.
• General Mentorship (30 min): I believe some of the most valuable things we learn come from conversations with people who've walked different paths than our own. Throughout my journey as a designer, I've been fortunate to meet people who have shared their experiences, challenged my perspectives, and helped me grow in ways I hadn't expected. I'd love to offer that same space to others. This session is open to anyone looking for a little guidance, encouragement, or simply a conversation with someone who's happy to listen. We can talk about your career, experiences, aspirations, lessons learned, or whatever feels meaningful to you at the moment. I'm not here as someone who has everything figured out. I'm still learning, experimenting, and growing myself. I believe mentorship can go both ways, and I'm just as interested in hearing your story as I am in sharing mine. No formal agenda, no expectations. Just an opportunity to connect, exchange perspectives, and hopefully learn something from each other.
