Organizations, tools, research
A working portfolio of organizations founded, tools shipped, and research and convenings led over the past twenty years.
Social enterprises and initiatives I founded

A founder-built organization making frontier AI safe for children: applied research, safety evaluations, red-teaming, and standards – evidence over alarm.

An advisory practice for safe, effective AI adoption in the social sector – strategy through implementation for NGOs, governments, and multilaterals.
A 66-researcher, 23-country fellowship, selected from about 180 applicants, building the evidence base on AI and child development.

A 13-person technology and innovation unit I founded inside a 4,300-person global NGO – I managed its product managers and seven-person software team; run on grant funding and earned revenue, it shipped open-source tools used in 60+ countries.

A global initiative against online violence against children, built from zero inside the world's largest independent child rights organization.

The Zoltner Consulting Group (ZCG) was a Santiago-based social enterprise designing and managing innovative ICT for Development (ICT4D) projects across the Americas.
Projects & implementations
DatAgro

An award-winning SMS market-information service for Chilean smallholders – early proof that technology built with its users outperforms technology built for them.
- FRIDA Award (Premio FRIDA), 2010
- Yahoo! Green Award – N2Y4 Mobile Challenge, 2009
- Social Justice Award – N2Y4 Mobile Challenge, 2009
- NetSquared Mobile Challenge Finalist, 2009
SaludMóvil / AIEPI Móvil

An SMS-based continuing-education service strengthening Peru's implementation of the Integrated Management of Childhood Illness (AIEPI) strategy in isolated Andean communities. One platform, two implementations: AIEPI Clínico reinforced clinical training for rural doctors, nurses, and nutritionists in Huancavelica, while AIEPI Comunitario supported community health agents working with pregnant women and young children in Huari, Ancash. Funded by the United Nations Foundation.
- World Summit Award Mobile – Peru nominee, 2011


A digital platform for Senegal's artisanal fishing economy – maritime safety alerts with GPS distress messaging, a virtual fish marketplace, digital financial services, and processing best practices, accessible by visual interface, voice, or AI chatbot. Fish processors grew their businesses ten-fold; fishermen raised incomes by up to $550 a year.
- WSIS Prizes 2020 Champion (ITU)

Climate adaptation information for more than 120,000 Ugandan farmers in their own languages – seasonal forecasts, agricultural advisories, and market prices over SMS, interactive FM radio, and community loudspeakers. Cut crop loss and damage by as much as 65%.
- UNFCCC Momentum for Change Lighthouse Activities Award, 2015

A CORFO-funded web and SMS platform connecting rural farmer communities in Chile – 340+ farmers trained, documented as a replication model.
- CORFO Rural Connectivity Competition winner, 2009
DatAgro
A multiple-award-winning mobile and SMS market-information service that raised the productivity of Chilean smallholder farmers and cooperatives, delivering crop prices and agronomic guidance straight to farmers' phones. The short animation explains how it worked – switch between English and Spanish narration below.

WISE – Wireless Solutions for Fisheries in Senegal
Senegal's fisheries employ more than 600,000 people – 17% of the national workforce – yet artisanal fishers and the women who process their catch are squeezed by a lack of timely price information, credit, and best-practice know-how. WISE, funded by Qualcomm Wireless Reach, put advanced wireless technology to work for them: an electronic fish-market price system and virtual marketplace, mobile-money loans through local microfinance institutions, maritime safety alerts with GPS distress messaging to the coastguard, weather and navigation information, and mobile video on processing best practices – accessible through a visual interface, voice commands, or an AI-powered chatbot. Fish processors grew their businesses ten-fold, from 100 kg to 1,000 kg of fish per person per month; fishermen raised their incomes by up to $550 a year; and Senegal's Food Security Commission now shares WISE market data with seven West African countries. In 2020 the UN's International Telecommunication Union named WISE a World Summit on the Information Society (WSIS) Prize Champion. A collaboration of FHI 360, Qualcomm Wireless Reach, Senegal's ministries of digital economy and fisheries, the Food Security Commission, Intermondes, and Free (formerly Tigo).
CHAI – Enabling Farmers to Adapt to Climate Change
In Uganda, where farming is mostly rainfed, drought and erratic weather hit hard and farmers get little information to cope. CHAI, implemented by FHI 360 and funded by Canada's IDRC, turned weather and market data into action: more than 120,000 farmers receive seasonal and short-term forecasts, agricultural advisories in their own languages, weekly crop and livestock prices, and low-cost rainwater-harvesting guidance – over SMS, interactive FM radio, community loudspeakers, and print, and two-way, so farmers text or call in questions and hear answers live on air. The project cut crop loss and damage by as much as 65% – worth $474–573 more per household each year – and received the UN Climate Change secretariat's 2015 Momentum for Change Lighthouse Activities Award, which recognizes innovative and transformative solutions to climate change.
Tools & platforms I co-developed

A cloud-based SMS messaging platform designed for novice users in rural, developing-country contexts – web-administered group messaging, two-way SMS, and automatic forwarding of RSS and Twitter feeds as text messages, receivable on any mobile phone. Built with DataDyne by Latin American developers, MIP powered DatAgro in Chile and SaludMóvil in Peru and drew replication requests from Argentina, Colombia, Guatemala, Kenya, Uganda, and the United States.
HAIA – Humanitarian AI Assistant
A generative-AI assistant built on the Humanitarian Data Insights Project, letting humanitarian teams query data and evidence in plain language.

A prototype ML classifier trained on real grooming conversations – behavior-level detection rather than content matching, named to IRCAI's Global Top 100 AI projects for the SDGs.
- IRCAI Global Top 100 – AI for the SDGs, 2021

Yo Agricultor
SMS prices, weather, and technical guidance for Chile's small farmers, commissioned by the Ministry of Agriculture – with a training video library past a million views.
Research & convenings I led

A five-country, child-centered framework defining technology-facilitated gender-based violence – built to guide prevention and response, not sit on a shelf.
Online Grooming Research

A seven-country, child-centered study of how children experience online grooming – evidence from children themselves, funded by the Tech Coalition's Safe Online Research Fund.

Youth Voices on AI

Youth input to the people building and governing frontier AI – with Western Sydney University, Australia's eSafety Commissioner, Save the Children, and Common Good AI, now feeding a youth-informed AI constitution.



Global convenings I co-founded

The USAID Symposium and GDDF tracks that made digital child protection a standing part of the global development technology agenda.
