Founding Head of Conversion
TLDR
Own the end-to-end conversion strategy, shipping high-quality landing pages rapidly while driving significant revenue through optimized user funnels and collaboration with key stakeholders.
Viktor is the AI coworker. It lives in Slack and Microsoft Teams, connects to thousands of tools, and does real work for real companies: finance, marketing, ops, engineering. We're building the product that replaces half the SaaS stack with a single teammate.
The team is small. The scope is not.
The Short Version
You're the person who owns every pixel between a paid click and a Viktor signup. You ship landing pages in three days, run real CRO tests instead of button-color theatre, and you have the taste to make pages that don’t look like templates. You ship fast — whether that’s in Framer, Webflow, or with AI coding tools at your side.
What's Actually Going On Here
Zeta runs serious paid spend across Meta and Google, scaling toward 2x volume in the next two quarters. Conversion is the lever that determines whether that spend pays off. At this volume, every point of conversion lift is six figures of ARR.
Right now there's nobody owning it end-to-end — landing pages, funnel optimization, CRO, site IA. You'll be the first.
No team above you. No team below you yet. You inherit live momentum: the Media Buying LP shipped recently and is already the best CPA in the account. The E-commerce LP and Agencies LP are next up. MS Teams expansion is imminent. The runway is paved. The job is to keep shipping, faster.
What You'll Actually Do
Run paid LP velocity. Net-new landing pages weekly. Ship-in-three-days as the standard for fresh LPs. Every paid sub-segment we open up gets its own dedicated surface, and you're the person making sure that surface exists before the spend turns on.
Run CRO experimentation. Four to eight live tests at any given time, two to three shipping per week by day 60. No button-color theatre — real tests on hypotheses that move the needle.
Own the signup funnel. Everything from paid click to the moment the user hits signup. Handoff to the Growth PM at signup. Until then it’s yours.
Own site information architecture. A 90+ day deliverable. You ship it incrementally, not as a big-bang redesign.
Ship solo, on whatever stack moves fastest. Framer, Webflow, or AI-assisted code — you pick the tool that gets the page live in three days, not the one that wins points on a tech-stack scorecard. A dedicated Growth Engineer joins in Phase 3 to take on heavier custom builds.
Work shoulder-to-shoulder with the CMO and the co-founders. Fryderyk and Peter care about how Viktor presents itself the moment a buyer lands. They'll have opinions on the page. You’ll have the data on what converts. The good calls win.
The Bar
This role is 1.5 jobs if you don’t prioritize ruthlessly. You’ll be measured on shipping velocity, conversion lift, and CAC efficiency — not on roadmap polish. You set the playbook because there isn’t one yet.
Day-1 Reality
Week 1: unblock E-commerce. Scope Agencies and MS Teams LP work. Take over Media Buying CRO.
How You'll Know It's Working
30 days: Site and funnel audit complete. Three CRO tests live. E-commerce LP unblocked and shipped.
60 days: Six-plus LPs. Ten-plus tests, three-plus winners. Paid-to-signup +10–15%. Rebrand migration plan ready.
90 days: +15% conversion lift vs day 30. LP production under three days. CRO at two to three tests per week. Vertical LP playbook documented.
Beyond that: paid spend keeps climbing because the math holds. New verticals get a surface before the spend turns on, not after.
Who You Are
3–7 years as a principal IC web lead, growth designer, or founding CRO at a PLG B2B SaaS or consumer fintech with $500K+/month paid spend.
You ship pages solo and at production quality. Framer or Webflow at the level where nobody can tell it’s no-code.
AI-native daily workflow. V0, Lovable, Bolt, Framer AI, Webflow AI, Figma Make — whatever gets the page live faster.
CRO rigor. Power calculations, hypothesis framing, real reads on real tests.
Taste. Your LPs don't look like templates.
Solo-shipping instinct. You don’t wait to be unblocked. You ship.
Founder mentality. You’re building a function, not inheriting one. You thrive with ambiguity, move fast, and figure things out.
EU primary (Warsaw, Paris, London, Berlin, Amsterdam, Helsinki, Stockholm, Istanbul). NYC secondary.
Why This Role Is Different
No layers. No design lead, no web manager, no CRO consultant between you and the work. You own the surface end-to-end.
The pages you ship will define how Viktor’s paid economics work. At this spend level, the difference between a good LP and a great one is real money every week. You’re not making landing pages. You’re choosing what the math does.
The product makes the pitch easier. The demo closes itself when the right buyer gets to it. Your job is the eight seconds before — making sure they want to.
The CMO and co-founders already believe conversion is strategic. You won’t spend your first six months convincing anyone that this matters.
Even Better If
You vibe-code. Claude Code, Cursor, Lovable — you can drop into React and Tailwind when no-code hits a ceiling, and you reach for AI tools to compress what used to take an engineer.
You’ve built a vertical-LP playbook from scratch and have the conversion data to show it worked.
You’ve owned a rebrand or domain migration without tanking conversion through it.
You’ve worked somewhere the founders had strong opinions about the brand and you loved partnering on it, not working around it.
How we work
Small team, high trust, low process. Decisions are made by owners, not committees. You will ship your first week. You will talk to users your first day. We don't do alignment meetings or stakeholder syncs. We build things, see if they work, and iterate.
Everyone here owns something real. Not a task. A surface of the company that customers depend on. When it breaks, you fix it. When it wins, everyone knows whose work it was.
We use Viktor to build Viktor. You'll see what you're working on in action every day.
Why Viktor
This is a rare window. The product works. The market is pulling. The team is small enough that what you do next week will be live in production next week. That doesn't last forever. Right now, it's still true.
Compensation
Competitive salary, meaningful equity, and the kind of ownership that only exists at this stage.
We're in Munich, New York, and Warsaw. Onsite preferred. The best work happens when you're in the room.
