Co-Founder & Chief Operating Officer · Sigilith
Sadia Ahmmed
Runs the commercial and operational path into regulated buyers, and researches whether the systems actually work for the people who must use them.
Sadia directs Sigilith's commercial strategy and operations: taking both the platform and Sentry into regulated institutions, and making deployments survive procurement, compliance review, and regulatory scrutiny.
Her research spans machine learning, computer vision and human-computer interaction (how systems behave across different populations and operating contexts), published at ICCV and NeurIPS workshops, with first authorship on a vision-transformer paper at ICEEIT. It bears directly on both products: whether a governance tool is genuinely usable by the compliance officers accountable for it, and whether verification holds for an entire population rather than its most convenient users.
She has led a 3,000-member technology organisation and directed national programmes with Grameenphone, Robi, and Therap, working directly with regulators, corporate leadership, and public-sector stakeholders across Bangladesh in both English and Bengali.
She graduated Summa Cum Laude from United International University, served as a Lecturer there, and is a Master's student and researcher at the University of British Columbia.

Co-authored with the founding team
Work that went through review together.
Sadia is a co-author on these 2 papers with both other founders. A team that has already published together is a different proposition from three people who met at a pitch event, so it is worth stating rather than leaving to be inferred from three separate CVs.
The company
What Sadia is building.
Sigilith is the authorisation layer for AI decisions. Regulated companies can’t ship AI into decisions that matter, because they can’t prove afterwards what happened. We sit in the path: the decision doesn’t go out until it’s policy-checked and sealed.
Two products run on that idea: the platform, which seals consequential AI decisions as they are issued, and Sentry, an eKYC and fraud decisioning system for regulated onboarding.
