Built by
a marketer and
developer.

Not an agency stitched together. Just one person who does both.

About Duology

Duology was built to fix the handoff.

Standard approach

I've seen this disconnect play out from both sides: campaigns launching before the site could handle them, sites shipping new features nobody was actually driving traffic to. Different teams, different priorities, and the client stuck in the middle, translating between them.

  • Marketing and dev working in separate silos, briefed separately
  • Campaigns launch before the site's ready to convert them
  • No one person owns the whole picture, so things get missed
  • Delays and confusion when something needs fixing on both sides
The Duology way

There had to be a better way. So Duology works differently - one point of contact who owns the brief, the build, and the growth plan. One timeline, no handoffs, nothing lost in translation.

  • One person across the whole build, from strategy to shipped site
  • Marketing and dev decisions made together, not in isolation
  • Nothing gets lost in translation between separate teams
  • A site built to convert, not just built to launch
Leadership

One person, every project.
