Challenger Sale Book - Global Sales Mentor | Zach Selch

In this brief video recorded at Viracopos Airport in São Paulo, Zach Selch reviews the sales book The Challenger Sale by Matthew Dixon and Brent Adamson, noting that it is sponsored by CEB, a firm that provides sales training and research on complex selling. Selch explains that the book advocates a non‑traditional, “challenger” approach—pushing back and challenging customers—to win complex, high‑ticket, long‑cycle deals. He emphasizes that the material is research‑driven, based on studies of buying and sales organizations, and recommends it primarily for mid‑career salespeople handling complex sales rather than beginners. Selch concludes with a brief promotion of his own international‑sales consulting services, inviting viewers to contact him when they are ready to expand globally.
