Big DealEnergy
Lessons From Win-Lab That Made Millionaires
The first book to fuse African sales mastery, financial literacy, and cultural intelligence into one professional reference: written from within Africa, for Africa, by a practitioner who closed the deals and built the team.

A desktop MBA, written in an African voice
Most sales and money books are imported wholesale from markets that assume different incomes, tax structures, and safety nets. This one was built for the African professional from the first page.
Two crafts, one book
Upgrade your sales craft and your personal financial intelligence at the same time, with the bridge chapter that connects the win to the wealth.
Field-tested, not theorised
Drawn from the Win-Lab Sales Accelerator and a distribution team grown from 6 to 150+ advisers, scaling Mansa-X, a CMA-regulated fund, from KES 246M to over KES 100B.
Globally compliant
Aligned to CFA Institute, CISI, OECD/INFE, and IOSCO standards, with risks presented as prominently as opportunities throughout.
Genuinely African
Chamas, stokvels, harambee, Ubuntu, black tax, and the diaspora are treated as real financial forces, named by country, never as decoration.
The science underneath
Every skill is explained at the brain level, with peer-reviewed neuroscience on trust, rejection, reward, and habit formation in plain language.
Built to be used
Each chapter closes with a 24-hour action and a Bloom's-aligned workbook, so the book functions as a self-directed programme, not a one-time read.
Four parts, 32 chapters, one journey
From the first cold call to the legacy you leave behind: a complete arc from sales warrior to wealth builder.
