You may find this call useful if you’re building a tech or AI-driven product and are facing questions like: • You have a product idea or early build, but are unsure what the MVP should include • Your product vision feels strong, but go-to-market planning is unclear • Execution feels busy, yet progress is slow or inconsistent • Product, engineering, and business priorities feel misaligned • You want an independent, unbiased perspective before a high-impact decision We’ll focus on clarifying: • What matters right now • What can be simplified, deferred, or removed • Where product, GTM, and execution are out of sync • Which decisions will unblock momentum fastest The conversation is diagnostic and practical. Because I’m not involved in execution, the guidance is focused solely on what works best for you.
