Stackflow — Revenue Operations Dashboard
Stackflow needed a single source of truth across Stripe, HubSpot, and Intercom. We built a real-time ops dashboard that replaced 6 manual spreadsheets and cut reporting time from 3 hours to zero.

Drivly — Lead-gen website redesign
Drivly's old site was generating 4–6 inbound leads per month. We redesigned the full funnel — positioning, copy, layout, and CTA architecture — and rebuilt it in Webflow in under 4 weeks.

What clients say

★★★★★

"Djamy & Kyle delivered the dashboard in 3 weeks, on budget, and it looked better than anything our internal team had produced in a year. It's now the first thing we open every morning."

LK
Lars Koopman
CEO · Stackflow
★★★★★

"We went from embarrassed to share our website to genuinely proud of it — in four weeks. The new site tripled our demo requests within the first month."

SM
Sarah Meijers
Head of Growth · Drivly
★★★★★

"Most designers hand you a pretty PDF and disappear. Djamy & Kyle understood our business, pushed back when we were wrong, and shipped code that actually worked. Highly recommend."

Two things we do better
than anyone else

Websites that convert, and dashboards that actually tell you something. Everything else follows from these.

Core offering
Conversion Websites
Bespoke websites engineered to turn visitors into leads. Every section designed with intent — hero, social proof, CTA, and everything in between.
Core offering
Custom Dashboards
Real-time data dashboards that connect your tools (Stripe, HubSpot, GA, SQL) into one place. Replace spreadsheets with decisions.
UI/UX Design
Research-backed wireframes and high-fidelity Figma prototypes. You see and approve the design before a single line of code is written.
Brand Identity
Logos, color systems, type scales, and component libraries — brand DNA that works consistently across every touchpoint.
Front-end Development
Production-grade code in React, Next.js or Webflow. Fast, accessible, SEO-ready — and handed off clean.
CRO & Analytics
Analytics setup, funnel audits, and A/B test design. We optimize the metrics that matter, not just the ones that look good.
Process

How we work together

A clear, structured 4-week process. You always know what's happening and what's next.

01
Discovery & Strategy
We start with a deep dive into your goals, users, and business model. This 2-hour session shapes everything that follows and results in a concrete brief and scope doc.
Week 1
02
Design & Prototype
Wireframes and high-fidelity Figma designs. You see exactly what we'll build before we write a single line of code. Two rounds of revisions are included.
Week 2
03
Build & Review
Pixel-precise development with a shared Notion board so you can track progress daily. A staging preview is live by midweek.
Week 3
04
Launch & Handoff
We handle the launch, set up analytics, and send you a full handoff document. One month of post-launch support included on all projects.
Week 4
The Team

Who you're working with

Two founders. One studio. No account managers between you and the people doing the work.

[ Djamy's photo ] Replace before launch
Co-founder · Design & Strategy
Djamy Wassink

Djamy leads design and client strategy at Vantyze. He started the studio after repeatedly seeing the same problem — companies paying for beautiful websites that never converted, and drowning in spreadsheets because no one had built them the right dashboard.

He's obsessed with the gap between looking good and performing well — and closing it for every client.

[ Kyle's photo ] Replace before launch
Co-founder · Development & Data
Kyle Bouman

Kyle handles the engineering side of Vantyze — from front-end development to data integrations and custom dashboards. Where Djamy designs the experience, Kyle builds the system that powers it.

He turns complex data and technical requirements into clean, reliable products that clients actually understand and use.

FAQ

Questions we always get

Most projects ship in 4 weeks. Starter websites can be done in 2–3. The timeline starts once you've approved the scope doc and paid the deposit. We'll give you a Notion board on day one so you can track progress in real time.
Starter includes 2 structured revision rounds. Growth and Scale include unlimited revisions. In practice, clients rarely need more than 2–3 rounds — because we agree on the direction in week one before a pixel is drawn.
For marketing sites we typically build in Webflow (easy for you to edit) or Next.js (if you need custom functionality). Dashboards are built in React with whichever data layer fits your stack (REST API, Supabase, PostgreSQL, etc.). We'll recommend what's right for your situation — never what's trendiest.
You provide the raw material — key messages, product info, any existing brand assets. We'll structure and polish the copy so it actually converts. If you need photography or video, we can recommend trusted partners in Amsterdam.
Perfect — we work with what you have. Bring your Figma files, brand guidelines, or even just a logo and a color palette. We'll build on your existing foundation rather than starting from zero.
Every project includes 30 days of post-launch support — bug fixes, small tweaks, and questions answered. After that, most clients move to a monthly retainer or come back for the next project. You'll never be left with a site you can't touch.
