For Mathew Pregasen, founder of the Letter Company, content that ignores a customer's brand is content that misses. The Letter Company builds Letterstory, and the team describes itself as obsessed with incorporating each customer's brand and messaging into its intelligence.
Context.dev supplies that brand context. Mathew expected another context API and came away calling it a truly incredible product for the company.
What is the Letter Company?
The Letter Company builds primitives for companies that treat marketing as an engineering problem. Mathew puts it simply:
"I am the founder of the Letter Company. We are building primitives for companies that treat marketing as an engineering problem."
Its platform, Letterstory, is an intelligent content marketing system for humans and AI agents. It curates topics, writes briefs, polishes articles, publishes content, and monitors how each piece performs. Customers choose from writing kernels with distinct styles and refine the voice to match their own.
Brand context at the center of the product
That promise depends on knowing each customer well. Letterstory's editing layer keeps drafts on voice, and its diagrams and tables follow the brand's visual identity. Every one of those steps needs an accurate picture of who the customer is and how they talk about themselves.
That is where Context.dev fits. Mathew connects the product directly to the company's core focus:
"Truly incredible product for the Letter Company given our obsession of incorporating our customer's brand and messaging into our intelligence."
More than yet another context API
Mathew went in skeptical. There is no shortage of APIs that promise context, and Context.dev looked like one more at first glance. Trying it changed his mind:
"Context.dev is one of those tools that looks like 'yet another context API', but then you try it and have your socks blown off."
Gold standard support
The product was only part of the experience. Mathew also called out the team behind it:
"As a perk, their support is gold standard too."
With Context.dev handling brand and messaging context, the Letter Company can keep its focus on what Letterstory does best: producing content that sounds like its customers and wins with agents, humans, and Google.
