Fractional GTM for devtools founders who need a senior marketer before they're ready to hire.
I work the way an in-house hire would: in your Slack, on your standups, deep enough in the product to shape messaging before a feature ships instead of explaining it after.
Most devtools companies lose their first year of compounding growth waiting for a hire who was already one quarter too late.
The window between early traction and a full-time marketing function is where organic authority and brand credibility either get built or don't. Companies that start later spend years catching up to whoever started earlier.
Rare Bird Lab works in a specific category: devtools, observability, database infrastructure, AI developer tooling. Technical products for technical buyers. Generalist marketing does not survive the scrutiny of a senior engineer audience. Knowing what a Terraform provider is, how SREs evaluate new tooling, and why "platform" language kills conversion with this buyer, that's the job.
What an engagement typically includes:
-
Sharpen how your product speaks to technical buyers so it holds up across every channel and stands apart from competitors.
-
Original technical content mapped to search intent and the buying journey, built to an editorial bar that earns trust with developers.
-
Launches, events, sales enablement, and AI surface visibility, coordinated around your calendar so nothing falls through the cracks.
Who Am I?
I’m Summer Lambert.
I have spent over a decade in B2B marketing. The last eight years, exclusively in developer tools.
That started at Instana, where I was an early marketing hire building go-to-market for an APM product selling to SREs and platform engineers. The complexity of reaching technical buyers, the precision the space demands, the culture of the ecosystem, it clicked immediately. I have not worked outside of devtools since.
In 2023 I launched Rare Bird Lab as a fractional GTM consultancy focused on a single category: devtools, observability, database infrastructure, and AI developer tooling. Since then I have partnered with 30+ companies across the landscape, from seed-stage infrastructure startups preparing for a first major launch to Series B observability platforms scaling their content and competitive positioning. That kind of focused repetition builds pattern recognition you cannot get any other way: what messaging actually resonates with engineering buyers, which competitive moves matter, where the positioning gaps are in a crowded category.
The methodologies behind Rare Bird Lab came from doing this work dozens of times and refining what holds up under real pipeline pressure. I challenge assumptions when the data points somewhere better, and I do not hand over a playbook and disappear. I operate inside your team, in your Slack, on your calls, close enough to the product to shape the narrative before a feature ships.
I am based in the Chicago area, fully remote since 2018, and work across time zones with clients around the world.
