Two years of executive long-form under CEO Sasha Orloff's byline, customer case studies such as Paradigm (YC W24), and production support for the Tech Finance podcast. Read the Puzzle case study.
For a developer-first product with an MCP-connected agent, StartupCookie wrote the developer onboarding guide that hands people the install command, plus lead-magnet content and product-in-action posts, all pointing at one activation moment.
Every number above is public and linked from the case studies. If a buyer can't check it, StartupCookie doesn't claim it.
What's different
Buyers have heard "AI-powered" from every vendor. Named customers and real projects cut through: Juno's OFX story puts a named customer and a real project on Juno's own domain, where prospects and AI search engines can find it.
Josh Davey's flagship post for Juno was about an Anthropic research study. It drew 745 reactions and 89 reposts, and the reposts matter most: other people chose to put it in front of their own audiences.
People researching AI tools ask ChatGPT and Claude before they talk to anyone. StartupCookie builds the pages those answers cite and tracks the citations. Tofu went from 7.00% to 67.38% visibility within six months.
The onboarding guide is the most important piece of content for a developer-first product. StartupCookie writes guides that hand people the install command and get them to value with no sales call.
StartupCookie runs its own production on custom AI agents built with Claude Code. Barbara walked through the setup on HubSpot's Marketing Against the Grain in August 2026.
