Design, build, and growth for San Francisco startups and Bay Area teams.

Stackzeno is a senior digital studio working with SF and Bay Area founders. We build custom websites, AI product sites, SaaS launches, and developer-tool experiences - fast, credible, and built to convert investors and users alike. Beyond the build, we ship the AI agents and automation that run behind it and handle the SEO and social that keep it filled.

Why Stackzeno

What San Francisco founders need from a digital partner

Engineering

Code your team will actually read

Typed Next.js, a documented component library, and a commit history worth reading. Your engineers inherit a codebase they can extend, not a black box they rewrite in six months.

Iteration

Built to change after launch

Positioning moves fast at seed and Series A. The site is componentised so your team can ship a new page or rewrite the hero without a redesign and another agency invoice.

Performance

Sub-1s load times

Custom Next.js on Vercel's edge network with real Lighthouse scores on every production build. Fast by architecture, not by a last-minute optimisation pass before handoff.

Market brief

What building for San Francisco actually involves

The buyers here are technical, they read your site like an engineer, and they will look at what it is built on. California's privacy rules apply in full.

Audience

Technical buyers evaluate the build itself

Founders and engineering leads in this market check load performance, look at the network tab and notice framework choices. A fast, cleanly built site is itself the credential, and a slow one undermines whatever the copy claims.

Privacy

CCPA and CPRA obligations still apply

The same California thresholds apply here as in Los Angeles. Startups frequently cross them faster than they expect, and retrofitting consent and rights-request flows after a funding round is worse than building them in.

Security

Enterprise deals drag SOC 2 into the website

Once a company starts selling upmarket, the marketing site gets pulled into security review: subprocessors, analytics, where form submissions land. Making those choices deliberately at build time saves a painful audit later.

Testimonials

What founders say

We told investors to just look at the site. It did the talking. That's the highest compliment I can pay a launch page.
CAFounderCapsule
We expected a marketing site. We got a conversion engine. Spend went up, CPL went down - that almost never happens at the same time.
