In 2013, Jan Okonji (pictured), tried his hand in business by creating a mobile application that he hoped to monetise. But after two years, he failed spectacularly, losing his capital investment of more than Sh3 million as well as a big deal worth over Sh30 million. However, the certified mental therapist picked up the pieces, restarted his business using the very lessons that led to his failure. With a renewed mindset, Okonji, who now runs Business Growth Solutions, a business consultancy firm, has trained hundreds of start-ups and SMEs. He shares some of these hard lessons with up-and-coming entrepreneurs.
