About

‍The sustainability management infrastructure

‍

At Ascend Tech, we have a simple belief: sustainability is not driven by intuition, but with reliable, traceable, and well-governed data.

‍

We build Harnest, the platform that allows businesses to understand, structure and use their extra-financial data to manage their ESG strategy and meet the growing requirements of their stakeholders.

‍

From regulatory compliance to impact management, Harnest is becoming the reference tool for all organizations that want to make their sustainable commitment a transformation lever.

‍

Our mission

‍

Enabling businesses to control their extra-financial data to manage their sustainability, demonstrate the management of their risks and value their positive impacts — with their customers, investors, employees and regulators.

‍

A response to the complexity of ESG standards

‍

The CSRD, the GRI, the SFDR, the SFDR, the VSME, the EDCI, the ISSB...

‍

Extra-financial frameworks are numerous, technical, and often incompatible with each other.

Harnest acts like a intelligent translator between these standards, by structuring a unified database on which you can produce all your extra-financial reports, without re-entering or inconsistency.

‍

An ambitious product vision

‍

We develop The ERP for extra-financial data, capable of orchestrating the collection, validation, analysis and reporting of all of an organization's ESG indicators.

‍

Our vision: that every company, but also its investors, insurers or banking partners, can access to the sustainability facet that is useful to them, based on the same sovereign data base.

‍

Our history

‍

Ascend Tech was born in 2023, from the encounter between two worlds:

• That of ESG and regulatory experts
  
  • Sabine Lochmann, Maxime Mathon, Ahmad Bidawi

• And that of data and software platform architects
  
  • Patrice Hiddinga, Fabien Herelle, Stéphane Jotic, Sophie Petitjean

‍

The first use case: CSRD. Today, we are extending our reach to all areas where extra-financial data is becoming strategic.

‍

Our team is based in Paris (Montparnasse Tower) and Bordeaux. We work in a network with an ecosystem of partners and independents to deploy quickly, efficiently, and with high standards.

‍

What makes us unique

‍

• One proprietary repository of extra-financial data, backed by a library of more than 70,000 ESG issues‍
• One Sovereign AI, based on Mistral, to help you analyze, document and write your deliverables
• A validated tool on the ground by the auditors for its robustness and auditability
• A platform designed for Piloting, well beyond simple reporting

‍

Who and with whom do we work?

‍

We support ETI, listed companies, industrial or technological groups, as soon as their managers want to make their ESG strategy a vector of performance, trust and differentiation.

‍

Our partners are consulting companies who rely on Harnest to industrialize their ESG missions, and law firms who trust us and present us to their customers.

‍

Our values

‍

• Ongoing progress : refusing the status quo, improving continuously
  
• Create the “Delight Customer” : go beyond satisfaction, create ambassadors
  
• Making a positive difference : impact human rights, the environment and the competitiveness of businesses

‍

Our culture

‍

A lot of ambition, carried out collectively.

We promote autonomy, accountability, and mutual support.

Little hierarchy, but a lot of rigor.

Because supporting companies on the difficult paths of sustainability requires more than a good product: it requires a common focus.
