About Us

Welcome to Tenacio. We’re really glad you’re here.

Why I Built Tenacio

Tenacio was born out of a desire to help people manage their varied workloads more effectively.

I’ve been consulting for 22 years, with the last 12 years as an independent consultant. My work spans many different areas—from crisis management exercises and traveller security training to designing bags and building applications like this one. With so many projects on my plate, I've often found myself overwhelmed. Often, I’d find myself unsure of what needed my attention the most, and I’d end up working on what I preferred or felt like doing at the moment.

Obviously, this approach isn’t the most effective way to get things done.

That’s where Tenacio comes in. At its core, Tenacio helps me make sense of a busy, diverse workload by clearly showing me what needs to be tackled next to stay on track.

My Story

I’m Grant, the founder of Spartan9 and the creator of Tenacio. Originally from Australia, I’ve called Singapore home since 2002 and have been developing applications on and off since 2009. Over the years, I’ve built a secure whistleblowing application, an incident management application, and an application for designing and running crisis simulation exercises.

The common thread through all of these projects is a commitment to simplifying complexity and helping individuals and teams work more effectively.
