Mariet observes an increasing focus on diverse representation within founding teams as a means to foster inclusive company cultures. However, she notes that improving recruitment processes is essential to further support women in tech and startups.

Mariet encourages women entering the tech industry to seek support and mentorship, emphasizing the willingness of many experienced professionals to assist newcomers. Building a strong knowledge base and skill set is crucial, but leveraging the support of those who preceded can provide additional benefits.

Among her notable achievements, Mariet highlights her role in developing the Optimus models at Bioptimus. The M-Optimus model, in particular, integrates various data types to advance research in cancer and drug discovery. This work signifies a shift from fragmented systems to integrated approaches in biomedical research.
