Jack Kelsey

I am a self-driven and commercially minded Customer Success and Sales Operations leader with over 8 years of experience in managing B2B relationships, leading consultative sales cycles, and scaling operational processes. My journey has taken me through high-growth startups and established sales environments, where I have consistently delivered standout client service across international markets.

Currently, I am the Owner and Director of GreenAir Horticulture Sociedad Limitada, where I founded and scaled a hydroponics retail business in Valencia, Spain. I successfully developed client relationships across Spain and Europe, generating a total turnover of €920k. My role encompasses all operations, including sales, pipeline development, hiring, vendor negotiations, financials, and customer service, with a strong focus on customer retention and B2B onboarding.

Previously, I served as a Senior Account Manager at Nutriculture DGS Ltd, managing 95 accounts with a turnover of approximately £7.2m. I increased portfolio performance by 12% year-over-year through effective relationship management and strategic upselling. My collaborative efforts in launching new products and introducing SLA policies have significantly improved pricing consistency and customer satisfaction.
