Our Mission: Fixing Trust in Commerce


-----------------------------------------


For a decade, we've been on a mission to close the Trust Gap--commerce's most expensive problem. In a world where distance and digital interfaces separate buyers and sellers, we're building the definitive trust infrastructure that enables global trade to flourish.


We recognise that trust is not binary but a spectrum, and our work continually expands the boundaries of commerce itself. Each improvement we make enables transactions that previously wouldn't have happened, revealing new frontiers where trust can be further enhanced.

Our Impact Today


--------------------


We've grown from an idea into the dominant force for trust in e-commerce:

Shopify's #1 Review Solution

: We've earned over 42k five-star reviews from merchants who rely on us daily

Global Scale

: More than 500k shops across 140+ countries use our platform

Massive Reach

: We process over 70 million orders monthly, generating 2 million+ verified buyer reviews

Organic Growth

: We've achieved 40% year-over-year growth purely through word of mouth--no paid marketing or sales teams needed

The Opportunity


-------------------


We're seeking a Full Stack Developer to build and maintain critical internal systems that power exceptional customer experiences at scale. You'll architect and develop sophisticated tools, integrations, and AI-powered solutions that directly impact our position as the #1 app in the Shopify ecosystem.
