For B2B SaaS companies

Demo portals. LLM SEO.
One client per market.

The B2B SaaS companies we work with don't lose buyers to "book a demo" friction. Their marketing site converts engineers and procurement alike, their structured data gets cited by ChatGPT and Perplexity, and their demo portal runs the actual product — not a slide deck.

What I build for B2B SaaS

Six things every SaaS marketing site actually needs.

Most SaaS marketing sites give you a hero, a feature grid, and a "book a demo" CTA. The ones we build do more than that.

Code editor01 · Convert
01

Marketing site, that converts engineers.

Engineers smell marketing-speak from a mile away. The site has to work for them too — clear docs surface, real code samples, an honest changelog, and pricing that doesn't require a sales call to interpret.

  • Engineer-friendly copy: real code samples, not marketing fluff
  • Pricing that doesn't require a sales call
  • Public changelog & status page
  • Honest comparison pages vs. competitors (where appropriate)
Convert engineers
Server infrastructure02 · Structured
02

Structured data, that LLMs cite.

Schema.org SoftwareApplication markup, llms.txt describing the product in machine-first prose, and author entity markup that tells AI models you are the source. The LLM SEO work that gets ChatGPT, Claude, and Perplexity to mention you by name.

  • Schema.org SoftwareApplication markup on every relevant page
  • llms.txt describing the product in machine-first prose
  • Author entity markup so AI knows you are the source
  • Citation tracking across ChatGPT, Claude, Perplexity, Gemini

Team demo03 · Demo
03

Demo portal, not a slide deck.

A real demo environment, sandboxed, with seed data the prospect can play with. They show up to the sales call already understanding the product — the conversation skips past the basics and into their actual use case.

  • Sandboxed demo environment with realistic seed data
  • Self-serve signup, no sales call required
  • Usage analytics so the sales rep knows what they explored
  • One-click handoff to a real account if they upgrade
Build the demo
Server racks04 · Docs
04

Docs site — that ships with the product.

Hand-styled documentation that matches the marketing site. Code samples with copy buttons. Changelog, API reference, quickstarts that actually work, and a search bar that finds the right page.

  • Hand-styled docs site matching the marketing brand
  • Code samples with one-click copy
  • API reference with request/response examples
  • Quickstarts that actually work end-to-end
Ship the docs
AI robot05 · AI
05

AI-citable content, that wins the citation.

When a buyer asks an LLM "what's the best [your category] for [use case]?" — the answer should be you. The content work, the author-entity work, the comparison-page work, and the citation-tracking dashboard.

  • Use-case pages that LLMs reach for as citation sources
  • Author-entity markup on every blog post
  • Comparison pages vs. named competitors (where the brand can take it)
  • Citation-tracking dashboard (where AI mentions you vs. competitors)
Win AI citations
SaaS team06 · Team
06

The team — real engineers, real founders.

B2B buyers hire the team as much as the product. Founder profiles with actual background. Engineering team with real expertise. Trust signals that don't read like a stock-options pitch.

  • Founder profiles with real backgrounds & previous work
  • Engineering team with expertise & open-source contributions
  • Customer-success & sales team faces on the site
  • Careers page that doesn't read like a Series-B pitch deck
