Turning good intentions into real impact.

Achieving your sustainability goals takes more than good intentions — it takes cultural change. We speak the language of your technical, sustainability and finance teams to make it happen.

DigitalPebble helps organisations turn their sustainability ambitions into measurable results — reducing both the financial and environmental impact of their cloud and on-premise operations. We work at the intersection of Green Software, GreenOps and FinOps. Decarbonisation and cost reduction aren’t competing priorities — with the right approach, they reinforce each other.

    Workshops & Training

    Upskill your engineering, finance and sustainability teams through hands-on workshops on GreenOps (measuring and reducing the environmental footprint of cloud systems) and FinOps (cross-team collaboration to maximise the business value of cloud spend). We walk practitioners through processing AWS Cost and Usage Reports, querying them with open source tools, and enriching them with environmental impact data using SPRUCE — our open source GreenOps platform. A pragmatic, low-commitment way to build internal capability — and a natural starting point for larger engagements.

  • Advisory

    Advisory

    Measuring the environmental impact of cloud is genuinely hard. Provider data is incomplete or misleading, the tooling landscape is fragmented, and the standards are still emerging. We start from the context that already exists in your organisation — the FinOps tools you’ve adopted, the sustainability objectives you’re committed to, the teams already involved — and help you build a GreenOps practice that fits. We advise on best practices, organisational patterns (the right roles, methodology and profiles to hire), and both commercial and open source tooling. Vendor-neutral, evidence-based, and grounded in hands-on experience. As certified FinOps practitioners, we treat cost and carbon as two sides of the same problem — most decarbonisation actions also reduce cloud spend.

  • Implementation

    Implementation

    Strategy without execution is just a slide deck. We design, deploy and operationalise the tooling that makes GreenOps real — from data pipelines and integrations to dashboards your teams will actually use. Backed by over 20 years of software engineering and architecture and a deep open source background, we deliver the engineering work ourselves rather than handing it off. Just as importantly, we bring a rare cross-disciplinary profile that bridges management, engineering and FinOps teams — turning measurement into measurable progress on both decarbonisation and cloud spend.

Julien Nioche — Founder & Director

Julien founded DigitalPebble in 2008. With over 20 years of software engineering and architecture experience across open source, research and consultancy, he brings a rare combination of technical depth and genuine sustainability conviction to every engagement.

He is the author of SPRUCE, an open source tool for estimating the environmental footprint of running services on AWS, and has spent his career contributing to major open source projects at the Apache Software Foundation. With DigitalPebble, he has helped organisations across sectors understand, quantify and reduce both the financial and carbon impact of their cloud operations.

What makes Julien’s approach distinctive is a rare combination of hands-on technical depth and genuine sustainability conviction. He works across engineering, finance and sustainability teams — translating complex cloud data into clear, actionable recommendations that treat cost reduction and decarbonisation as two sides of the same problem, not competing priorities.

Julien is a certified FinOps practitioner from the FinOps Foundation, a Champion at the Green Software Foundation and a member of Boavizta and the Apache Software Foundation.
