Rayon’s mission
Rayon is building the next generation of architectural design software: more collaborative, simpler, smarter, and more beautiful.
The design of buildings and spaces has a huge impact on our lives. Climate change, affordable housing, sustainable urbanization, and the future of work are all challenges that will require us to design a better and more efficient built environment.
Although architectural design is, by nature, a collaborative endeavor, the tools currently used by architects and designers are not built for collaboration or knowledge sharing. They are complex, expensive, and stuck in a pre-internet era, with desktop computers as their primary paradigm.
We are building a browser-based, collaborative, real-time multiplayer editor to democratize architectural design and empower designers to create more efficient spaces and buildings.
Who are we?
We are a small team of 35+ people passionate about web technology, architecture, and the built environment. First and foremost, we love building amazing tools for creators.
Rayon was co-founded in October 2021 by Bastien Dolla, an engineer from École Polytechnique and Ponts et Chaussées with 15 years of experience in technology and real estate, and Stanislas Chaillou, an engineer and architect from EPFL and Harvard with a background in machine-learning research applied to architecture.
Rayon raised a €4 million Seed round, backed by world-class investors including Northzone, Foundamental, Seedcamp, 20VC, and Kima, as well as amazing business angels such as Ralph Gootee, co-founder of PlanGrid; Joe Thomas, co-founder and CEO of Loom; architect Norman Foster; Rasmus Andersson, formerly of Spotify and Meta; Thibaud Elzière, founder of eFounders; Nicolas Steegmann, co-founder of Stupeflix; Riggs Kubiak, founder of Honest Buildings; and Jonathan Widawski, founder and CEO of Maze.
Rayon is a French company based in Paris. We are open to remote candidates located in time zones close to Central European Time.
What will you be doing?
As Rayon’s Head of Growth, you will own our growth strategy and execution across the entire product-led growth funnel, from awareness and acquisition to activation, conversion, retention, expansion, and revenue.
This is a senior, highly hands-on role. You will combine strategic thinking, experimentation, analytical rigor, and strong execution to build a repeatable growth engine capable of driving revenue at scale.
More specifically, you will:
Define and own Rayon’s growth strategy, GTM roadmap, targets, and operating cadence.
Take ownership of the entire PLG funnel, identifying the biggest opportunities and removing friction at every stage of the user journey.
Build a deep understanding of our users, acquisition channels, product usage, conversion drivers, and revenue dynamics.
Develop and scale a content-led growth engine, including editorial content, SEO, use cases, templates, educational resources, and other formats that attract and convert our target audiences.
Build, manage, and optimize paid-acquisition campaigns across relevant channels, including search, social media, video, sponsorships, and emerging platforms.
Design and implement SEO and SEM strategies that generate sustainable, high-intent traffic.
Partner closely with Product, Product Marketing and Design to improve onboarding, activation, conversion, retention, monetization, and in-product growth loops.
Identify, test, and scale new growth opportunities, including partnerships, communities, referral programs, affiliates, influencers, events, and other distribution channels.
Build a rigorous experimentation framework, running frequent tests and turning successful initiatives into repeatable systems.
Define, monitor, and communicate the key metrics that drive growth and revenue.
Manage growth budgets and allocate resources based on expected impact and return on investment.
Build the foundations of Rayon’s growth organization and, as the company scales, help recruit and lead a high-performing growth team.
Work directly with the founders and collaborate across Product, Product Marketing, Design, Engineering, Sales, and Customer Success.
