About Duuabl
Built by people who ran a trades business.
Not a tech company that studied the problem. A team that operated inside the trades for years — tracked €123M in contracts and saw exactly where things broke.
B2B contracts tracked
Years combined trades experience
SaaS launched
01
The problem
The problem wasn't demand. It was operations.
We built and ran a trades marketplace. Matched contractors with commercial clients across building, repair, and maintenance. Tracked more than €123 million in B2B contracts. Watched hundreds of jobs move from enquiry to completion.
We saw what happened on both sides of every job. Demand was not the bottleneck. Tradespeople had more work than they could handle. What stopped them from growing was everything that happened around the actual work.
Quoting took 45 minutes per job. Planning lived inside people's heads. Cash flow was invisible until it became a crisis. Growth was capped by what the founder could personally track.
02
The decision
We closed the business deliberately.
In early 2026, we shut down the marketplace and the service business. Not because they failed — because what we had learned made a different problem more important to solve.
The tools available to tradespeople hadn't changed in a decade. Jobber served recurring service trades. ServiceTitan served enterprise. Nothing served the construction micro-business with an AI-native system built around how site work actually happens.
That gap is Duuabl. That conviction is the product.

What we're building
An operating system. Not another app.
Duuabl is not a point solution. It's the infrastructure layer for a trades business — quoting, job management, payments, compliance, referral network — all connected, all trade-specific.
We are building it trade by trade. Each trade gets its own workflow, quote templates, compliance fields, and pipeline stages. We are starting with Toronto and Ottawa, then expanding across Canada before moving to the UK.
The goal is to become the infrastructure every trades business runs on. The Shopify for the trades sector.
The team
Three founders. One shared reference point.
We each came to this from a different angle. The product reflects all three.
Tavi Maastik
CEO & Co-Founder
Operator turned founder. Built and ran businesses inside the trades sector — a marketplace matching contractors with commercial clients, direct experience on both sides of how jobs get won, delivered, and paid for. Came to this problem because I lived it, not because I modelled it.
Kaspar Triebstok
CTO & Co-Founder
Civil engineering and IT engineering — both degrees, fully used. Kaspar has spent his career building software for the physical world. At Duuabl he designs infrastructure that understands construction logic, not just construction workflows. Building for scale from day one.
Märt Mõistus
BDM & Co-Founder
20+ years in construction — site management, general contracting, trade partnerships. Märt has run crews, read thousands of quotes, and managed supplier relationships across the full project lifecycle. He is the reason Duuabl speaks the language of the trade, not the language of software.
The opportunity
408,000 businesses in Canada running on spreadsheets and gut feel.
The competitive whitespace in construction software is specific and defensible.

Gap
Competitive whitespace
Jobber serves recurring home services. ServiceTitan serves enterprise. Neither serves the construction micro-SME doing project-based work.
Jobber dominates recurring services — lawn care, cleaning, pest control. Not construction. ServiceTitan validated that trades businesses pay serious money for the right tool. Neither serves the construction micro-SME doing project-based work.
Duuabl fills the gap. Built for the complexity of construction and renovation without the enterprise overhead. The right tool for the 90% of contractors the market currently ignores.
