Clarity when things get complicated.

I help product and brand teams articulate what they’re building at high-stakes moments.

For when the language has to hold up.

I’m James Aviaz, founder of Modern English.

I’ve worked in-house at Uber and Spotify, navigating rapid growth, product change, and stakeholder complexity.

Today, I work with teams at ambitious product and technology companies on narrative and messaging across launches, product changes, and repositioning.

The result is language teams can align around and communicate with confidence.
