Calin brings genuine, hard-won expertise to the world of AI transformation. Not as a theorist, but as someone who has actually built his own company in the space. His deep knowledge of the AI landscape is both broad and precise, and working with him gave me a far clearer understanding of a field that can feel overwhelming from the outside. He doesn't just explain what's possible he helps you see opportunities you hadn't considered before. What truly sets him apart is his rigor and commitment to delivery. Calin doesn't just meet expectations he’s someone who constantly over-delivers. I trust him fully to help companies harness AI in ways that are meaningful and lasting. And through it all, he is a superb communicator and executor, someone who makes complex things feel clear, and ideas feel achievable.

Calin advised me and my team while we were building an AI SDR product, and his input materially shaped where we ended up. We came to him with a fairly common early-stage problem: strong technical foundation, a working prototype, but conflicting opinion internally about what to prioritise and how to position. Calin helped us tremendously at this stage. He helped us sharpen our ICP, restructure the roadmap around the workflows that actually drove buyer value (rather than the features we were attached to building), how to plan a roadmap that aligns with the needs of our buyers and pressure-tested our agentic architecture choices in ways that saved us real engineering time downstream. He helped us all the way from "low-level" product challenges i.e. conducting user interviews, synthesis, roadmap planning all the way through to strategic analysis and vision planning, marketing mapping etc. Constantly giving us the right advice for where the business was. He was equally strong on the GTM side. He helped us rethink our positioning, articulate a sharper wedge against the crowded AI SDR category - which trickled down into our marketing, and gave us a clearer framework for how to talk about human-in-the-loop to buyers who were sceptical of fully autonomous outbound. He also had useful, candid views on pricing, onboarding, and what early enterprise pilots realistically need to look like. Beyond the strategic work, Calin is a high-quality operator to think alongside. He's commercially minded and technically fluent. I would work with him again in a heartbeat and have recommended Calin to many of my entrepreneurial friends.

I brought Calin in when there was a lot of internal interest around AI, but not necessarily alignment on where to focus or how to operationalize it. He quickly helped narrow a long list of ideas down to the few opportunities that truly mattered, then stayed closely involved through implementation and the agentic build. What impressed me most was his ability to bridge strategy, technical detail, and stakeholder management seamlessly. He’s comfortable in conversations with executives, risk teams, and engineers, which made him incredibly effective to work with. Margo Lau, VP, Financial Services

I had the pleasure of working with Calin and witnessing firsthand him leading AI strategy and transformation work for us. He is exceptional at mapping out the current information and process flow, understanding stakeholder involvement, and navigating both complex technical and interpersonal corporate landscapes. Really impressed by his deep expertise. Not sure what we would have done without him!

I am happy to vouch for Calin based on his outstanding professional background, leadership experience, and deep expertise in AI strategy, product development, and organizational transformation. Calin has built and led products and teams at an exceptionally high level, including leadership positions such as Chief Product Officer and Product Director within globally recognized organizations and startups. His experience spans AI, product strategy, startup growth, enterprise transformation, and executive leadership across both B2B and B2C environments. What stands out the most is his combination of strategic thinking, execution capability, and strong interpersonal leadership. He has consistently demonstrated the ability to operate in highly demanding environments, scale organizations, lead multidisciplinary teams, and drive innovation across complex domains. Based on his experience, achievements, and leadership track record, I strongly believe Calin would provide tremendous value as a coach and advisor on the Leland platform.
