Hello! I’m Stefan Tilke.

I design it.
Then I build it.

Brands, websites, products, you name it.
These days I build a lot of it with AI.

INFO

I’m a designer and AI creative technologist at Salesloft. I work on our brand and website, and use AI to build cool stuff.

Before that I designed travel websites for millions of visitors at Simpleview, including a Gold dotCOMM winner, and brands, websites and products for startups as a freelance creative strategist. My whole career has been in marketing and brand, across web, product and visual design. I’ve always been a problem solver, and with AI I can now build the fix too.

Outside of work I’m usually building something with AI: small tools, visual experiments, things I wish existed. The best ones end up in the Lab.

Born in Yerevan, Armenia, raised on both coasts of the U.S., and now at home in Sunnyvale, California.

How I work with AI

AI writes the code. The taste, the standards and the final call stay with me.

  1. 01

    Context before code

    Before the first prompt I gather everything: brand files, templates, references and the rules nobody wrote down. Slide Creator started with hours of preparation before a single line was written.

  2. 02

    Art direct, don’t accept

    The first version is only a start. I use what we build, notice what feels off and keep pushing until it feels right. Most of the best features, like the guided tour, the help panel and the brand guardrails, came from that.

  3. 03

    Check everything

    I don’t trust a first pass, mine or the AI’s. I measure the output against the source files, test the edge cases and fix the details nobody asked about.

  4. 04

    Keep building

    What AI can do changes every month, so I find out by making things. The Lab is where that happens.

Let’s make something good.

Freelance · 2025

An AI product website shown on a laptop.

Full website design for an early-stage AI startup.

The startup helps brands control how they show up in AI search: in ChatGPT, Gemini and AI overviews. With a working product and early brand assets in place, they brought me in to design the public website. It had to explain a category few people understood yet, and earn the trust of enterprise marketing teams.

Most competitors’ sites were jargon-heavy and visually flat. I built a calm, spacious system instead: Gelica headlines over Lato, one iris blue accent, and AI-assisted imagery with an oil-painted texture, a nod to the mix of creativity and technology behind the product.

In short

Clear, calm, credible.

A category few people understood yet, explained in plain language, on a system calm enough to earn the trust of enterprise marketing teams.

Freelance · 2025

A venture capital website shown on a laptop.

Website redesign, Webflow build and brand support for a venture firm.

A venture firm backing technology in healthcare, infrastructure and defense. I designed their first website and visual identity in 2021, and they brought me back to redesign and rebuild the site as the firm grew.

The new site had to feel credible to founders, partners and public-sector stakeholders without the usual venture clichés. Dark backgrounds, sharp type and the firm’s signature blue carry it, with simple motion graphics that explain the philosophy at a glance. I built it in Webflow, so it loads fast and grows with little development work.

Their first website and identity in 2021, then a redesign and a Webflow rebuild as the firm grew. Credible to founders, partners and the public sector, and it grows with little development work.

Visual effects studio · personal · 2026

Live

Phosphor FX Lab

A real-time visual effects studio for the web. Stack dither, ASCII, halftone, glass, light, fluid and real 3D in any combination, make it react to the cursor, and put it live on any website.

Phosphor started as a dither tool, because everyone loves the look and I wanted to do so much more with it. It grew into a creative tool for the web that’s powerful, useful and easy to use, for anything from a quiet background, a hero section, a card or a loader to something completely wild.

Start from a photo, a video, a 3D object or a generator, then stack any effects on top, in any order, blended like layers in a design tool. Every combination is a new look, and there are more than anyone could try. Any setting can animate or follow the cursor, and every change renders live, so an idea takes seconds to try. Your imagination is the only real limit.

When it’s right, export a still, a seamless loop or a live embed that drops onto any website and keeps reacting. It goes deep, but it’s quick to learn: pick a template and make it yours.

How I got here

Made to keep growing.

What began as a dither tool kept growing: halftone and ASCII, glitch and CRT, glass, light, fluid, real 3D and video. It still gets new effects, generators and templates all the time, and every one stacks with everything already there, so each addition multiplies what you can make. The best way to see it is to try it.
