Transform your organisation’s impact measurement in just 12 weeks
Â
We believe the best impact measurement systems are built in-house - by the people making the impact, not outsourced to someone who isn’t. That’s why we created the IMPACTT Accelerator.Â
Thousands of staff are responsible for measuring and demonstrating the difference their team or organisation makes to people’s lives.Â
But most have had to figure it out on their own.Â
Often, there’s no impact specialist in the team, no clear framework, and no formal support or training - just the pressure to “show impact” on top of everything else.Â
The IMPACTT Accelerator gives people the skills, tools and confidence in just 12 weeks to build a system that works, without needing to hire in a consultant or reinvent the wheel.
