Lean Startup, to Lean Company, to Rich Exit shares the remarkable story of Dr. Kenan Sahin, who took $1,000 in savings and used it to undertake the most extraordinary entrepreneurial journey, culminating with a $1.54 billion rich exit.Kenan was teaching at MIT in the 1980s and sought to validate his many academic theories in a real-world lab. So he founded a startup to begin testing innovations in organizational development-challenging nearly every business best practice of the 1990s and largely transforming those practices. Among Kenan's critical insights into rich-exit business success include...Suffusing the organization with a "teach and learn, learn and teach" mindsetEmpowering every team member to practice "situational leadership"Leveraging a lean team with "splitsuit" systems architecture developmentRecruiting and retaining the nation's finest talent by hiring based on aptitude > attitude > willingness > experience (in order of importance)Turning performance reviews into company improvement exercisesImproving on traditional profit-sharing formulas with a "gain sharing" formulaFinding a way to reject outside funding and retain full ownershipReplacing notions of customer satisfaction with "customer success"Finding the work/life balance that maximizes team productivityBridging disconnects between sales & production, end-users & IT, management, and R&DLeaping the chasm from a service-based to a product companyCombining judicious simplification with ambiguity tolerance to master complex situationsFlattening internal communications so anyone can access anyone elseMaking "smart interruptibility" an accepted practice at every level of the companyDeveloping the "bins, balls, and backplane" framework of modern user interfacesRejecting the "Big IP Lie" and writing "peace contracts" to drive rich-exit potentialAfter just 17 years, Kenan's company, Kenan Systems, was acquired by Lucent Technologies and he remained the sole shareholder. Importantly to him, all of his 750+ employees also benefitted from the exit. This is the inside look at how it happened. This is a field-tested framework for building a lean startup into a lean company and then a rich exit-the perfect model for any aspiring entrepreneur.Since Kenan also pioneered large scale commercial AI and big data systems, the framework and principles of innovation he developed are even more relevant in today's marketplace.
