His knowledge and experience of and influence in the industry grew so phenomenally that the music press of the nation labelled him "Kongi" - a sobriquet that stuck with him throughout like a leach. Artistes from rival companies sought after him as they became envious of those under his company's label. It was not long before the biggest record company in the country, PolyGram, went after him as CBS took over from them the crown of "Record Company of the Year" - a title which hitherto had been their exclusive preserve.
He joined PolyGram in 1990 for a record-breaking seven-figure salary as the A&R and Promotions Manager and won back the "Record Company of the Year" from CBS. He later became the General Manager of the company from where he resigned after four years of glorious service. During his stint at PolyGram he tended the careers of such artistes as Ras Kimono, Oritz Wilkey, Victor Essiet's Mandators, Evi-Edna, Alex O, Charley Boy and launched the careers of others like Blackky, Edmund Spice and Segun Arinze amongst others.
Along the line, he mentored the likes of Elder Zeetei Debekeme, the former Press Secretary to Governor Alamesiegha of Bayelsa State; Tony Alenkhe , the former Promotions Manager of Sony Music and the former Promotions Manager of Premier Music Dayo Olomu
