“ESG is not a reporting exercise for us. It is a commercial mandate. We needed a system that enables us to apply the same discipline we use for our clinical GxP processes and that produces audit-grade data we can trust.”

Jo-Ann Rodriguez, Global Head of Compliance, Quality and ESG, Saama Technologies

“KEY ESG has enabled us to deepen engagement with our portfolio companies and capture the high-quality data essential to Ambienta’s mission of delivering world-leading sustainability performance.”

Francesco Anichini, ESG Manager

"I would recommend KEY ESG because they understand that great outcomes come from working together to deliver customer value. […] what stands out is how well the team listens and acts on feedback from both us and our consulting partners. That collaborative mindset is a real differentiator."

Lizzy Peijs, Compliance Officer and Legal Counsel

"Both KEY ESG's platform and the customer support team have enabled us to tackle CSRD processes with confidence and look beyond compliance to achieving our sustainability goals."

Ayperi Sevincli, Global Head of Sustainability

“KEY ESG’s platform has been easy to use from the outset. It has enabled us to bring the skills required to calculate Scope 1, 2 and 3 carbon emissions in-house. This has not only saved expensive consultant fees, but also given us autonomy over the whole process.”

Verity Lakin, Sustainability Partner

“KEY ESG provides the flexibility we need and caters to our very specific reporting requirements – the platform is able to handle all our custom metrics, across each of the different countries, and the support team were even willing to onboard us ahead of time to allow for our upcoming reporting deadlines. I can’t fault the software and the support – I recommend them 10 out of 10.”

Vanessa Zerbib, Head of Quality and Sustainability

"Aside from huge time savings and improvements to our data accuracy, we were able to import two years’ worth of carbon emissions data into the platform, analyse it, and make strategic decisions about how we can reduce our emissions."

Alex Qinhong Wu, Sustainability Engineer

"Using KEY ESG, we can easily segment the data to reveal opportunities for improvements regarding sustainability."

Joost Puls, Financial Controller

“We wanted to turn the ESG data into business efficiency. We are now seeing the first wave of data-driven conversations around sustainability and benefitting from the superior insights we can draw from them.”

Johan Boonaert, ESG Manager

“KEY ESG has helped us get organised and get the data together to tell a compelling story around our sustainability strategy.”

Caitlin Heffley, Head of Customer Service

"KEY ESG enabled us to streamline and centralise the reporting process and customise the metrics so that they are relevant for our business.”

Benjamin Negre, ESG and Risk Manager

“KEY ESG has got a very granular range of metrics and data values which means that it is versatile enough to handle the complexities of MAAS Aviation’s reporting requirements.”

Yuriy Bolonny, ESG Officer

“KEY ESG has increased the transparency and collaboration of our sustainability reporting process. We have moved away from disconnected data sheets saved in various locations, to a single source of truth platform which enables us to form a clear action plan.”

Chris Roose, Senior R&D Manager

“KEY ESG enabled our whole portfolio to participate in the EDCI benchmark process. The rapid onboarding allowed all our companies to collect and report on the required EDCI data within one month. We could not have moved this fast without KEY ESG."

Gabrielle Rubenstein, Co-founder and Managing Partner

“Of the four platforms we have used for ESG reporting, KEY ESG is the most engaging and educational: you understand why you need to provide the data and how to gather it.”

Emile Fyon, CEO

"KEY ESG is user-friendly and makes submitting data and ESG reporting easier for our portfolio companies.”

Gilles van Hulle, Legal Counsel

“We set out originally to improve efficiency at the fund manager level and have been delighted to see efficiency improvements trickle down to the portfolio company level and deliver added value."

Carmen Navarro, Head of ESG

“Using KEY ESG has enabled us to establish a credible emissions baseline, make a commitment to the SBTi, and to deliver on the sustainability requirements of one of our largest customers. This has positioned sustainability as an important value driver of the business.”

Ann Masson, CFO

“KEY ESG has made it simple to understand ESG, especially carbon accounting for Scope 1, 2, and 3 reporting. Capturing all the required data for our sustainability reporting was a daunting task at first, but KEY ESG has helped us put a strong process in place and deliver on our goal.”

Rocco Meraglia, VP of HSEC & Sustainability

“Using KEY ESG’s dashboard enabled us to align internally on our D&I goals and report our results in a frictionless, streamlined way. The platform is so simple to use and makes ESG ambitions achievable for companies at every level of tech and ESG maturity.”

Martin Kennington, CMO of 365 Finance

In KEY ESG we found a software and implementation partner that can upskill companies at different levels of ESG maturity.

James Munce, CEO

"The KEY ESG platform provides us with a centralized view of our ESG data, streamlines data collection and drives ESG engagement across our portfolio companies. It provides a platform which fosters data-driven decision making."

Liz Platt, Strategy Associate

"In KEY ESG we have found a software partner that understands the unique challenges and needs of investment managers as well as company management teams. With their software solution we can automate and scale ESG data collection, metric calculation and reporting processes, allowing us to focus our time and energy on driving real improvement in ESG performance across our portfolio."

Didier Ryelandt, CFO of ForMotion

"Our portfolio companies love how easy to use the platform is and have already mentioned they want to use it for their own internal ESG processes."

Alison Collins, Head of ESG

“KEY ESG enabled our team to produce our first ESG report within one month. Their software enabled our team to quickly cover the ESG basics and contextualize our ESG performance for internal management as well as external stakeholder communication purposes.”

Yuri Mayor, CFO
