Tree-Nation is the world’s largest reforestation platform, connecting citizens and companies with verified planting projects across the globe. Since 2006, over 800,000 users and 30,000+ companies have planted more than 45 million trees through our platform, across 40+ active reforestation projects worldwide.
We combine technology and environmental impact to make reforestation simple, transparent, and scalable. Our goal is to plant 1 trillion trees by 2050 and we’re building the platform, the automation, and the systems to get there.
Our team spans many nationalities, backgrounds, and disciplines. What we share is a mindset: we take ownership because we care about what we’re building, we don’t back down from hard problems, and we trust each other to lead, make decisions, and ask for help when needed.
We are investing heavily in automation and AI to scale our impact. The company provides access to the latest LLMs — including Enterprise Claude, ChatGPT, Gemini, and more — and we strongly encourage everyone to innovate.
We’re based in Barcelona and work primarily from the office, because the energy of working side by side matters to us.
You’ll design and run Tree-Nation’s first-ever Customer Success function — a one-to-many, data-driven operation covering B2B SMB accounts. Your tools are dashboards, automated alerts, and templated sequences, not spreadsheets and manual check-ins. You’ll prevent churn, drive wallet refills, and surface expansion opportunities across the entire non-enterprise portfolio.
This is a leadership role by nature — you’ll define the playbooks, dashboards, set the standards, and shape how Tree-Nation takes care of its growing client base.
Customer Success is evolving fast — from 1:1 relationship management to scaled, AI-powered, revenue-driving operations. We’re building for where CS is going, not where it’s been. You’ll work closely with our tech team to shape how the platform serves clients, your feedback loop directly influences what gets built.
You’ll report directly to Max, CEO and co-founder, and sit within the Growth team alongside Account Management, Sales, Customer Support, and Growth Marketing. This means you’ll have direct access to the people handling enterprise accounts, inbound leads, support escalations, and campaign strategy.
To be clear on boundaries: Customer Support handles technical and operational issues. Your focus is commercial health, retention, and expansion.
Own the health and retention of B2B accounts, monitoring wallet balances, planting activity, and engagement signals daily
Build and run proactive intervention flows like wallet top-up prompts, flatline detection, and winback campaigns to prevent silent churn before it happens
Drive activation follow-through for newly onboarded accounts: ensure they launch their forest, brand it, announce it, and build a sustainable planting habit
Identify and execute standard expansion opportunities (volume increases, new planting occasions, seasonal campaigns)
Quantify and champion client feedback to tech and business unit managers
Define where the human/product boundary sits: which accounts should self-serve, which need intervention, and what the platform needs to build to make that work
Collaborate with the Tech team to build the dashboards, health scores, and automated alerts that make one-to-many CS possible at scale
Escalate complex commercial opportunities to Sales and technical issues to Support, keeping handoff protocols clean and context-rich
Use AI tools daily (Enterprise Claude, ChatGPT, Gemini, HubSpot workflows, automated sequences) to multiply your reach across hundreds of accounts

Mindset
High ownership — you take initiative, but you also know when to listen first. Tree-Nation does things differently, and the best people here understand context before trying to change it
Open and direct communicator — we give each other honest feedback because we want everyone to grow, and we expect the same openness in return.
Systems thinker — you look for the root cause, not the quick fix. You build processes that work at scale, not band-aids that break at 50 accounts
Self-driven and curious — you’re motivated by the impact of your work, and you actively seek out better ways to do things
Mission-aligned — reforestation isn’t a marketing line for you. It’s the reason you’re reading this

The Tree-Nation Difference
Your lifetime carbon emissions are offset through monthly tree planting from the day you join
Personal tree-planting allocation to plant and gift trees, however you choose
A sustainability-designed office in Barcelona built to reflect the mission you’re working toward
A small, high-trust team where your work has a visible impact from day one — you’ll work directly with the CEO and Growth team, not through layers that filter your input
Direct exposure to product, tech, and strategic decisions
A place where failure is part of the process — if nothing is failing, we're not pushing hard enough
If something clicked while reading this — the mission, the way we work, the kind of challenge we’re describing — we want to hear from you.
We don’t hire based on pedigree. We hire based on how you think, what you’ve built, and whether you’ll make the people around you better.
We're looking for people who make the team better. Come prove it.
