Hi, I’m Sonja Lee 李澄

I help growth-stage companies get competitive or sensitive launches right, and avoid expensive mistakes.

I spent fifteen years at Google running marketing programs with industry complexity. That ranged from nine figure campaigns for the world’s largest OS, to driving usage of public health tech at the height of the pandemic with zero budget.

I now bring seasoned product marketing and go-to-market expertise across consumer, developer, and enterprise.

Whether you need strategic positioning and vision-setting, build partnership ecosystems, or demand generation, if you seek marketing leadership without a full-time hire, let's talk.

Ways we can collaborate

1 High-Stakes Launch Strategy

Your business involves sensitive partnerships, shifting competitive dynamics, or regulatory scrutiny.

I develop marketing and communications strategy for the long haul, while driving execution of present day road maps — without triggering backlash.

2 On-Demand PMM Expertise

Your team is stretched thin or tackling something outside their wheelhouse: a brand repositioning, entering a new market or selling to a new customer type.

I create new capacity for your team to ensure no momentum is lost.

3 Fractional Marketing Leader

You need senior marketing leadership but aren't ready for a full-time hire.

I embed with your team 2-3 days per week to build strategy, establish processes, and guide teams through complex launches or build new capacity.
