Case Study
Hey Eduardo
A privacy-first AI desktop app needed a marketing site that could convert security-conscious professionals into one-time-purchase customers — without subscription friction, without trust shortcuts, and without sounding like every other AI tool on the market.

About the Client
Hey Eduardo is a private, on-device AI desktop assistant for Mac — purpose-built for CPAs, financial advisors, insurance agents, and consultants who handle confidential client information. The product runs entirely on Apple Silicon, with zero data ever leaving the user's machine, positioned as the privacy-first alternative to ChatGPT for professionals with regulatory and ethical obligations.
01 / The Challenge
Where they were
before us.
Selling a privacy-focused AI product is harder than selling another ChatGPT wrapper. Hey Eduardo's audience is suspicious by profession — CPAs, financial advisors, consultants — and skeptical of marketing copy by default. The site had to communicate three difficult ideas in a single visit: (1) the product is genuinely private (not just claimed-private), (2) the on-device AI is actually capable, not a toy, and (3) the one-time pricing model is sustainable, not a trick. A failure on any of those three would lose the sale before the buyer reached pricing.
02 / Our Approach
What we
actually did.
Brand and positioning workshop centered on the 'architecture, not policy' framing — translating the technical privacy story into copy that resonates with non-technical professional buyers
Custom visual design system with quiet authority — clean typographic hierarchy, restrained color, and an interactive product demo that lets visitors see the local AI in action without leaving the page
Animated 'Eduardo conversation' module on the homepage built to demonstrate real product capability rather than describe it — the single highest-converting section on the page
Dedicated audience landing pages for the three primary professional segments (CPAs, financial advisors, insurance agents) — each speaking the specific compliance and confidentiality language of that role
Full Next.js build optimized for Core Web Vitals from the first wireframe — sub-1-second LCP on mobile, perfect CLS, INP under 100ms — because a privacy product that loads slowly contradicts its own promise
Ongoing maintenance partnership: weekly performance monitoring, feature page updates as the product ships new capabilities, blog and SEO content cadence, and A/B testing of pricing and CTA placement
03 / The Solution
What we
delivered.
Full custom Next.js build with a conversion-focused architecture, audience-segmented landing pages, and a live product demo that does the convincing the copy can't. Post-launch we transitioned to an ongoing maintenance and growth partnership — shipping new feature pages, performance tuning, and conversion optimization as the product evolves. Visitor-to-purchase conversion rate sits at 4.2%, which is roughly 2.5× the SaaS industry benchmark for one-time-payment software.

Discovery to launch
Nerd Stack actually understood what we were building. Most agencies wanted to make us look like every other AI startup — Nerd Stack helped us look like the only one taking privacy seriously. The site converts security-conscious professionals at a rate I didn't think was possible for a self-serve product.
