The challenge

Sustainability reporting is no longer a nice-to-have. Under the CSRD (Corporate Sustainability Reporting Directive), companies across Europe now have to measure, document, and disclose the environmental impact of their products with the same rigor they'd apply to financial statements.

The brief was demanding on every axis at once: the data model had to hold up to regulatory scrutiny, the interface had to make complex environmental data legible to non-technical teams, and the build had to move fast enough to hit a live product window of just a few months.

At dcycle we handle supplier data, supply chains, and regulations that change every quarter. Turning all of that into a reliable product for our clients is as much a data engineering challenge as a software one: pipelines that can't fail, models that have to scale, and a domain where every calculation matters. Tailor Hub was the partner we needed. They understand your architecture and your business, and they build with you. That difference changes everything. I'd work with them again without hesitation.

The client

dcycle is a climate-tech company building the tooling that lets organizations measure, report, and act on the environmental footprint of what they produce. Their flagship product, the dcycle LCA Tool, turns raw product and supply chain data into clear, auditable sustainability metrics, giving sustainability and product teams a working system instead of a spreadsheet.

The tech

Tailor Hub partnered with dcycle on the dcycle LCA Tool, working directly with the team to take the product from concept to a live, in-house-built platform.

  • Frontend: Next.js (SSR), built for speed and clarity on dense sustainability data.

  • Data visualization: react-chartjs-2 for reporting views, @tanstack/react-table for structured data tables.

  • Export: React to Print, so LCA reports can move straight from the platform into audit-ready documents.

  • Data layer: Google Sheets API / JSON endpoints, keeping dcycle's data pipeline flexible as their model evolves.

  • Infrastructure: deployed on Vercel across staging and production.

  • Process: design in Figma, project and task tracking in Linear, with a shared Notion hub keeping dcycle and Tailor Hub aligned on decisions, changelog, and deliverables in real time.

The culture

What's made this partnership work is how dcycle and Tailor Hub build together. With Tailor Hub's support, dcycle has established itself as one of the companies leading the way in agentic engineering, treating AI-first workflows as a working practice rather than a talking point.

That relationship has grown well beyond the codebase. It's what brought both teams together for Ahead, the event Tailor Hub hosted at DIMAD in Madrid, where dcycle shared how their teams actually work, in front of a packed room, with feedback that exceeded expectations on every front.
