I'm Justin Kestelyn (call me JK), founder of Filament. I sharpen positioning and go-to-market strategy for technical B2B founders, so the market understands why you win before you spend more on building pipeline.
Most early-stage B2B teams don't struggle because the product is weak. They struggle because a buyer or user can't tell, within seconds, what problem gets solved, why this product is different, and why any of it matters to them.
The usual response is to spend more on selling: more meetings, more content, more demand generation. That treats a clarity problem like a volume problem. But it doesn't work.
Every engagement (fractional, retainer, or project-based) starts with a free 30-minute call, scoped to your needs.
Early-stage companies are my sweet spot. If you're further along, these are the signals that still make it a fit:
I've done this work as a product marketing or devrel leader everywhere from a 10-person incubator team inside Google to Cloudera during its run from startup through IPO, with stops at Bugcrowd and Oracle along the way. Different scales, same intersection: the technical user who has to trust the product, and the economic buyer who has to justify it.
Different stages, different products, the same failure every time: the technology was ready before the market had the words for it. The teams that won weren't the ones with the best feature set, they were the ones who closed that gap first.
AI can draft you positioning options in minutes. What it can't do is tell you which one is true for your market, because it wasn't in the room at Cloudera's sprint to IPO or inside that ten-person Google team when a pitch landed, or watched one die.
