BigSIS sustainable world

BigSis business model

BigSis is an R&D-based company that develops sustainable insect control solutions for agricultural, public health and other pests.

Our focus is to sell these solutions to end users via established distributors. BigSis sterile male insect production and release units will be small scale, typically serving a few thousand hectares of the relevant crop across multiple customer sites.

Starting with insects where growers are desperate for new solutions, BigSis will progressively address dozens of commercially valuable pest targets, in agricultural, public health and other sectors. The first two pest solutions are chosen for speed to market and competitive advantage: codling moth and spotted wing Drosophila; mosquito solutions are high priority, too.

BigSis is meeting the challenge of integrating biology, engineering and artificial intelligence through its team of seasoned executives.
