Sajnani founded Kingpin in 2021 as a B2B SaaS solution that connects brand distributors to retailers. Today, Kingpin empowers distributors of over 200 brands, including Guess, On, Reebok, Skechers, Billabong, Jockey, and Sam Edelman, giving them access to over 4,000 retailers across 75 countries. It has raised $3.5 million from investors, including COTU Ventures, Outliers Venture Capital, mu ventures, Infinity Ventures, Hub71, and angel investors. In 2016, Sajnani launched his first company Si Fashion, a fashion distribution business, to diversify his family's portfolio beyond textiles, manufacturing, and retail. That business grew to over $10 million in wholesale sales in four years.
