Hi, this Ryan Kidd answering on behalf of MATS Research!

MATS is currently fundraising for our 2026 programs and beyond. We are the largest AI safety research fellowship and talent pipeline, supporting 100 fellows twice a year. Some impact stats:

• 446 alumni and 120+ arXiv papers (h-index 37) in 3.5 years.
• 80% of our pre-2025 alumni work on AI safety and 10% founded AI safety orgs or teams (e.g., Apollo, Timaeus).
• Participants in our last program rated it 9.4/10 on average.
• Former team members have gone on to (re)found Constellation's Astra Fellowship, manage Anthropic's AI safety external partnerships, and help other AI safety orgs scale.

We are well-funded by Coefficient Giving, but have big scaling plans! We want to run an additional fellowship in Fall 2026, expand Summer and Winter 2026 programs to 120 fellows each, and launch a 1-2 year residency program for senior researchers. Each additional fellow costs $40.8k.

Some testimonials:

• "Apollo almost certainly would not have happened without MATS." Marius Hobbhahn (CEO, Apollo Research)
• "It's my number one recommendation to people considering work on Al safety." Jesse Hoogland (Executive Director, Timaeus)

Hi, this is Liz Hixson answering on behalf of New Incentives. 

We provide small cash incentives to encourage childhood vaccinations in northern Nigeria, an area with some of the highest under-five mortality rates and lowest vaccination rates in the world.

We are currently raising funds to extend our program in 11 states in northern Nigeria through the beginning of 2029, enabling us to reach an additional ~1.8 million infants and protect them from deadly diseases such as measles and pneumonia. 

Small cash incentives are proven to double childhood vaccination rates in rural Nigeria (you can read more about the results of an RCT here). Your support will enable us to sustain our program, reaching new birth cohorts (donate directly here). 

In case you want to dive in and learn more about our program:

• Here’s a recent blog post that gives a glimpse into what an immunization day is like at one of the clinics where we operate.
• Here’s an in-depth report on our vaccination coverage surveys from earlier this year.
• Learn more about the history of the organization and our pivots and failures along the way.
• Learn more about how we work with government and partners on the ground.
