Delivering more... than ESG box-checking.

Harvest exists to help private market investors turn ESG from a compliance exercise into a strategic advantage. We give GPs, LPs, and portfolio companies the clarity, confidence, and tools they need to collect better data, make smarter decisions, and deliver more meaningful outcomes.

We believe ESG should drive value, not just reporting.

Part of Dasseti

Harvest is part of Dasseti, a global investment data firm trusted by many of the world’s leading asset managers, allocators, and consultants. Founded in 2018 by Wissem Souissi, Dasseti brings together AI, automation, and human insight to revolutionize how investment data is collected, validated, and used.

In early 2025, Dasseti acquired Metric ESG, a purpose-built ESG platform for venture and growth capital. The combination of Dasseti, Metric, and Harvest creates a unique offering: end-to-end ESG support across the full private market ecosystem.

Why we exist

Sustainability and performance are no longer competing priorities. In private markets, they’re increasingly one and the same.

We built Harvest to help investors unlock ESG as a lever for better outcomes, not just better optics. Because good ESG data isn’t about ticking boxes. It’s about making smarter decisions, building stronger businesses, and leading with confidence in a world that demands it.

Our mission

To help investors, fund managers, and private companies harness ESG data to power sustainable performance, with less admin, more insight, and greater strategic clarity.

Our belief

We believe companies were built to solve problems, not contribute to them.

That sustainability should be measurable.

And that the right ESG tools can help you build something that lasts.
