Mark Hendriks
Design partner for founders, turning complex ideas into scalable products.
I work with founders on complex B2B and B2C products that are hard to get right. Products where the real work sits below the surface.
I’ve spent 15+ years in startups, working closely with engineering, sales, and customers as products take shape. That experience shapes how I approach design, from system-level thinking down to the details that matter.
I often join early, and stay involved as the product and team grow.

Testimonials
Having Mark join was transformative for Spara. He singlehandedly drove product design through the company’s first two years. His work helped us move fast with confidence, communicate our vision to customers and investors, and scale from a small founding team to more than twenty people. The clarity and quality he brought early on were key in helping us reach major milestones, including our $15M funding round, and continue to influence how we build today.
ZP Zander Pease
CTO, SparaMark's ability to create visually stunning and contemporary UIs truly sets him apart. His ability to understand the problem we were trying to solve and our target audience was evident from the start. He sets clear expectations and consistently meets them. Collaborating with him has been a headache-free journey, and I am truly grateful for his incredible design work.

Work

GTM AI agent platform for engaging, qualifying, and routing leads across multiple channels.
I joined as the first designer when the team consisted of just the founders, and have led product design as the company has grown to a team of 20+. The work evolved as the team grew, from shaping the initial product to supporting enterprise organisations and increasingly complex, multi-channel workflows.
- https://workbymark.nl/adtribute
Marketing attribution platform that connects fragmented data to map cross-device customer journeys.
For Adtribute, I worked with the team to help large organisations understand cross-device customer journeys. The focus was designing an interface that combined fragmented data sources and complex attribution models into something customers could confidently use day to day.
Champify
https://workbymark.nl/champifySales intelligence platform that surfaces timely company insights for sales teams.
For Champify, I worked on two projects helping sales teams at companies like S&P Global, Zuora, and Retool act on company intelligence without being overwhelmed: an email system that surfaced bite-sized signals with links to deeper context, and an in-product insight card system that combined structured data with natural language while minimizing cognitive load.

Developer-first sync platform for building flexible customer data integrations.
Lightyear is a developer-first sync platform for SaaS companies to deliver flexible customer data integrations. I co-founded the company, led product design and brand, and was responsible for go-to-market strategy. The involved designing for a highly technical audience while validating product and positioning directly through customer conversations.
Interseller
https://workbymark.nl/intersellerRecruiting outreach platform for sourcing candidates and running multi-step email sequences.
I worked alongside the founders of Interseller for several years as the team and customer base grew. I helped prioritise product development as the platform scaled to handling millions of emails each day, balancing customer and business needs. This work contributed to the company’s acquisition by Greenhouse.
- https://workbymark.nl/startmonday
Mobile-first job application experience used by recruiters across different brands.
I worked with Start Monday to reduce drop-off between seeing a job post and applying on mobile. The system I designed scaled across many languages, from Spanish to Dutch, and adapted to brands as different as Uber and H&M. The main challenge was balancing a consistent experience with local and brand-specific requirements.
