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 money more trying to sell it.
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, or 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 starts with a free 30-minute call, scoped to your stage.
I've been a product marketing, developer marketing, and devrel leader at Cloudera, Bugcrowd, Google, and Oracle, from pre-IPO startups to global enterprises. That work sits at the intersection of two audiences that rarely get equal attention: 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.
Yes, AI can draft you simple positioning in minutes. What it can't do is know which version is actually true for your market and users, or make the bet on where the category goes next. That takes years of contextual experience watching this pattern play out.
