Measure impact. Deliver change.
Fortell Impact helps organisations collect outcome evidence and deliver programmes at scale — reaching the people traditional methods miss.
One platform to measure impact and deliver change
How we reach people
Three channels, one platform — meet people where they already are.
Voice calls, no internet needed
We connect an AI voice agent to a local phone number in your deployment country — in any language, from any basic handset.
Web-based conversational survey
Share a link via WhatsApp, SMS, or email. The same AI agent runs in the browser — no app download required.

Proof from the field
Jhpiego in Malawi
Voice-based evaluation of VMMC services
Jhpiego compared AI analysis with human experts and found high agreement (κ = 0.75)—showing voice-based AI produces insights as reliable as traditional studies.
IDB Lab in Latin America
Portfolio-wide impact monitoring across three countries
IDB Lab replaced costly one-off evaluations with AI-powered voice interviews across Venezuela, Chile, and Ecuador — capturing lived-experience data at portfolio scale for a fraction of the cost of traditional RCTs.
UNICEF in Mozambique
National consultation for strategic planning
2,300+ people reached in under a week. Results arrived in time to inform strategic discussions, not after decisions were made.

What our partners say
"Avatar-based surveys captured the richness of respondents' experiences and significantly lowered our costs."
"Participants engaged comfortably with AI avatars, reducing costs and security risks where in-person visits are challenging."
"Clients spoke honestly with our Chichewa avatar — privacy, cultural familiarity, and dignity shaped how they engaged."
"Participants shared their real experiences freely, without any external influence shaping their responses."
