TavaSIS is built by ZYT Pte. Ltd. — a Singapore-based sustainability practice and GSTC Member. Our founder has completed the GSTC Sustainable Tourism Auditor Course for both the GSTC Hotel Standard and the GSTC Tour Operator Standard. We believe technology is an enabler. By combining practitioner expertise with purpose-built tools, we accelerate the adoption of sustainability in the tourism industry — making certification accessible and achievable for every tourism business.
Achieving GSTC certification is a rigorous process — hundreds of performance indicators, each requiring specific evidence, consultant review, and CB verification. For most tourism businesses, the process plays out across WhatsApp threads, email chains, shared drives, and printed forms passed around between teams.
Evidence gets lost. Revision cycles drag on. Consultants spend hours on paperwork instead of guidance. Clients lose momentum. And when the CB auditor arrives, no one can find the document they need.
These aren't failures of intent — they're failures of infrastructure.
TavaSIS is a structured tourism sustainability certification management platform that connects tourism businesses and consultants in a single workflow — from initial readiness assessment through to documentation package completion.
Every performance indicator is systematically managed. Evidence is tagged and stored against each requirement. AI guidance provides a requirement brief to help teams understand what evidence is required, and generates a starting template for each performance indicator. Consultants review, request revisions, and validate — all within the platform, with a full audit trail.
When the CB auditor arrives, every performance indicator is documented, every piece of evidence is indexed, and the full audit trail is intact.
GSTC certification should be the start of a destination's sustainability journey — not a one-time exercise. TavaSIS is built to support continuous improvement, not just audit readiness.
Tourism businesses and their consultants are stretched. Every hour spent chasing documents, managing email threads, or reconstructing evidence trails is an hour not spent on what actually matters. TavaSIS exists to take that weight off — so the effort goes where it belongs.
TavaSIS is designed to be inclusive — for tourism businesses of every size, consultants across every market, and various certification frameworks. Sustainability is a shared goal. The platform should be too.
Our Mission
To make sustainable tourism certification accessible, structured, and achievable — for every tourism business, in every market.
ZYT was founded by practitioners with hands-on experience in sustainability certification across ESG and GSTC frameworks. We built TavaSIS because we understood what tourism businesses and consultants actually face — and because no tool existed that addressed it properly. That practitioner perspective is embedded in every workflow, every performance indicator brief, and every stage of the platform.
TavaSIS today solves the certification workflow problem. Our roadmap takes the platform further — toward becoming the sustainability compliance infrastructure that connects tourism businesses, their supply chains, certification bodies, and sustainability vendors, with GSTC certification as the entry point.
