David J. Bland is the co-author of Testing Business Ideas and founder of Precoil. He helps executives make assured decisions—Commit, Correct, or Cut—before committing millions, using a proven system of Reality-Based Innovation and innovation risk management.
As an independent arbiter of reality, David works with leadership teams to surface hidden risks in growth strategies and issue evidence-based verdicts in weeks. His work has protected companies from wasting millions on bets that won’t scale—and created millions more by proving which ideas drive growth.
Before founding Precoil, David spent 11 years in startups—one success, two failures—that revealed a consistent pattern: companies ignored customer problems and built what they thought was right. That experience shaped his approach. For the past decade, he has guided Fortune 500 leaders in embedding business model testing and reality-based gates into their funding decisions, ensuring capital is allocated with evidence, not opinions.
Today, David partners with executives worldwide as a keynote speaker, corporate innovation advisor, and growth strategy partner—delivering assurance for bold strategies, protecting capital, reducing risk, and scaling what works.
Most new products fail, but Testing Business Ideas shows leaders how to flip those odds. Building on Alex Osterwalder’s Business Model Generation, this practical guide equips teams with proven techniques to validate ideas quickly and decisively.
By making assumptions explicit and testing them with evidence, the book helps organizations reduce risk, avoid wasted investment, and increase the likelihood of scalable success. It extends the Business Model Canvas and Value Proposition Canvas with Assumptions Mapping and a library of lean, real-world experiments that turn bold strategies into reality-tested decisions.
Testing Business Ideas delivers a practical, visual guide for turning bold strategies into evidence-based decisions.
Reduce wasted time, money, and resources by exposing weak ideas early.
Close the gap between high-level strategy and hands-on validation.
Surface and test critical assumptions using tools like the Business Model and Value Proposition Canvases.
This manual helps leaders replace intuition with facts—embedding an experimental mindset and building a repeatable process for making confident, scalable growth decisions.
Don’t wait until years of wasted investment to say, “I wish we had brought David in sooner.” Too many companies spend millions building products nobody wants—only to realize too late that the bets were never grounded in evidence.
David J. Bland helps executives prevent that cycle. Not every idea will succeed, but every test delivers clarity: Commit, Correct, or Cut. Instead of relying on intuition, he brings quantitative and qualitative evidence leaders can defend. The result? Smarter capital allocation, faster decisions, and the confidence to scale what works.
David has been helping organizations test and scale bold ideas since 2010, working with agencies, startups, and Fortune 500 executives alike. Along the way, he realized the need for an independent standard—and founded Precoil to provide it.
He is the bestselling author of Testing Business Ideas, a sought-after keynote speaker at global conferences, and a trusted partner to executives who need evidence-based decisions before committing millions.
