We built the tools we needed.
Then we realized everyone else needed them too.

Syntac didn't start in a boardroom. It started in the field.

David spent over a decade building organizations in the psychedelic therapy space — including facilitating Canada's first legally exempted psilocybin therapy in Alberta. He trained practitioners, launched conferences and founded ATMA, that generated millions in revenue, building systems from scratch because the tools didn't exist yet.

Chris grew up watching industries get disrupted by technology that didn't understand the people using it. He became a realtor — not because he wanted to watch from the sidelines, but because he wanted to know, from the inside, what professionals actually need versus what tech companies think they need.

When AI started reshaping every industry overnight, most people fell into one of two camps: fear or hype. We chose a third option. We started building.

Not theoretical products. Not pitch decks. Working tools — tested on real transactions, real client conversations, real deadlines. The kind of tools that a realtor pulls up at 9pm before a listing presentation, or a therapist uses to prep for a difficult session the next morning.

AI doesn't replace expertise. It amplifies it.
The best realtor with the right AI becomes unstoppable.

We discovered something that Silicon Valley keeps getting wrong: AI doesn't replace expertise. It amplifies it. The best realtor with the right AI becomes unstoppable. The best therapist with the right AI has more bandwidth to be present with their clients. The best tradesperson stops losing work to paperwork.

That's what Syntac does. It learns how you work, protects your data like it's sacred, and makes your day measurably better — without asking you to change a thing.

Built by practitioners, not theorists

We use Syntac every day in our own work. If it doesn't survive contact with reality, it doesn't ship.

Privacy isn't a feature — it's the architecture

Your data is yours. We don't train on it, sell it, or “anonymize” it for someone else's benefit. Full stop.

AI that knows you

Syntac doesn't just respond to commands. It learns your patterns, anticipates your needs, and gets smarter the longer you use it. Think of it less like software and more like a brilliant associate who never forgets a detail.

David Harder

Founder

Three decades of building companies. A master's degree in religious studies that taught him to ask better questions. Executive Director of SYNTAC Institute, and former founder and CEO of Catalyst Psychedelic Conference and ATMA Journey Centers where he helped facilitate Canada's first legally authorized psilocybin therapy in Alberta.

Then life did what life does — it rearranged everything.

David rebuilt from scratch in his fifties, diving into AI not as a tourist but as someone who needed better tools to do the work that mattered. Thousands of hours building, breaking, and shipping later, Syntac is the result: AI that works the way humans actually think. Safe, effective and helpful.

Chris Harder

Co-Founder

Licensed realtor who got tired of watching technology miss the point. Chris doesn't build from assumptions — he builds from the daily reality of managing listings, running comps, prepping for client calls, and competing in markets where the margin between good and great is measured in response times and preparation.

He's the reason Syntac's realtor tools actually work in the field. When a feature gets proposed, Chris is the one who pressure-tests it against the question that matters most: does this make my next deal better?

Father and son building something neither could build alone — domain expertise meets decades of systems thinking, and the result is software that feels like it was made by someone who's been in your shoes. Because it was.
