S M Jishanul Islam
Architects both products end to end: the record formats and verification paths the platform rests on, and the liveness engine Sentry runs on.
Jishan owns Sigilith's engineering: the deterministic record formats, the sealing and verification paths, and the distributed infrastructure both products depend on. He has architected and delivered AI systems for the Government of Bangladesh and TELUS International, leading engineering teams from concept through deployment.
His published research spans EACL, ICCV, NeurIPS and IEEE venues, covering multimodal learning, computer vision, OCR, and verifiable-record systems. That range maps onto the company directly: provenance and integrity primitives for the platform, liveness and capture forensics for Sentry.
The overlap is not incidental. BornoDrishti, his Bangla OCR work published at EACL, addresses the extraction problem on Sentry's document-intelligence research roadmap: diverse, degraded, non-Latin scripts that defeat template-based systems.
He builds for reliability first: production systems held to institutional standards of performance, security, and scale.

Co-authored with the founding team
Work that went through review together.
Jishan 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 Jishan 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.
