What if impact investing didn’t rely on vague promises, but on clear, measurable data from day one? That’s exactly what Tau20 is here to solve.

Developed within the CLARIFAI project, Tau20 is an AI-powered platform designed to help early-stage startups and investors speak the same language when it comes to impact. It brings structure, clarity, and credibility to how social and environmental value is defined and measured, right from the start.

Why Tau20 matters

Today, many impact-driven startups struggle to access funding, not because their ideas lack value, but because their impact is hard to quantify using traditional ESG frameworks. The result? Missed opportunities, misaligned expectations, and in some cases, impact-washing.

Tau20 changes that.

It enables founders to structure their impact early, while giving investors clearer, more comparable insights when making decisions. The goal is simple: align innovation, capital, and purpose, without slowing companies down.

What participants are saying

The first cohort of the Impact Readiness Sprints has already shown what’s possible when impact meets structure:

“I found it an excellent platform! It transforms qualitative impact goals into quantitative scores, providing the data-driven evidence required to satisfy ESG investors.” – EdCortex

 

“We found the TAU20 process genuinely useful for sharpening our impact narrative and sense-checking our metrics against investor expectations. The structured format pushed us to be more precise about our theory of change and our evidence base, which was valuable at this stage.” – CoachBridge 

 

“The experience with testing the beta version of the TAU20 AI tool was really insightful for our startup. It provided us with a clear impact classification and a very relevant list of IRIS+ aligned KPI’s to measure our impact as the business evolves and efficiently communicate it to investors.” – MIMA Technologies

What are the Impact Readiness Sprints?

These sprints are designed for early-stage startups ready to turn their impact narrative into concrete metrics.

Through a structured, hands-on program, participants:

• Conduct a self-assessment using Tau20 (reviewed by experts)
• Define 3–5 core impact KPIs aligned with SDGs and IRIS+
• Build an investor-ready impact narrative
• Develop a clear measurement plan
• Connect with impact VCs and business angels for feedback

It’s built specifically for founders preparing for pre-seed or seed fundraising, accelerator applications, or first conversations with impact investors.
