Log inDayNew was created out of a simple but powerful realization: the hardest seasons of life don’t come with a roadmap—and most support shows up briefly, then fades.
After CEO Karine Nissim lost her husband unexpectedly, she experienced firsthand how overwhelming grief and life disruption can be, even when surrounded by care, casseroles, and flowers. What she needed most wasn’t a moment of support, but something that lasted—practical tools, guidance, and community that could meet her in real life, over time.
Drawing on her background as a tech entrepreneur, Karine along with Eloise Bune founded DayNew: a modern app designed to support people through grief, loss, transition, and reinvention.
DayNew brings together structure and compassion—combining guided tools, thoughtful prompts, and community connection—to help people feel less alone and more capable as they move forward, one day at a time. Whether you’re navigating loss, major change, or a season of personal growth, DayNew is here to support you—not just at the beginning, but for the long haul.
Karine is the founder and CEO of DayNew. Her work is shaped by lived experience—becoming widowed suddenly, rebuilding life as a mother of three, and learning how to move forward without bypassing what’s been lost.
Before DayNew, Karine co-founded DogVacay, which later merged with Rover and became a public company. She has spoken at large tech conferences like Emerge Americas at the Miami Beach Convention Center in addition to influential organizations like YPO and Strategic Forum.
Prior to co-founding DayNew, Eloise founded the camping start-up, Tentrr, with her late husband Michael. Eloise was also the Founder and CEO of Handwriting.io where she guided the company through groundbreaking development of her handwriting replication software, four US and international software patents, product development, as well as B2B and B2B2C sales and operations. Handwriting.io was acquired in 2018.
When Eloise is not building companies, she consults DayNew and enjoys advising start-up founders, sailing, gardening, cooking, entertaining and raising her twin girls.

Sherry Nasseri
Dr. Sherry Nasseri has built her career helping people to navigate the mental health challenges that impact their quality of life. She has connected physical and behavioral health to form a holistic view of what a patient is experiencing to assist them in a more fulfilling and balanced life.
After successfully completing her graduate studies and training, she assumed a leadership position at HealthCare Partners (now known as Optum). Her role involved pioneering a program within hospital settings, focusing on patients aged 65 and older who were grappling with high-risk chronic conditions, often resulting in undiagnosed depression. The program’s groundbreaking work drove the field of medicine to begin recognizing the connection between physical conditions and mental health.
One of the major initiatives Sherry spearheaded at HCP was a program that studied how underserved populations and cultures experienced and coped with high-risk medical issues and end-of-life conversations. The team created innovative methods for delivering culturally-sensitive, critical medical information to elderly, and poverty-stricken patients. Their success enabled them to implement partnerships in the program with leading Los Angeles hospitals including UCLA, Providence Dignity Health, and Cedars-Sinai. This eventually led to her work as Director of Palliative Care at Health Essentials Medical Group.
Today, Sherry works in private practice with clients as they navigate challenges with aging, career, marriage, illness, and family. She lectures at various universities, such as USC and UCLA. She and her husband, Pardis, are proud parents of son, Kasra ’35, and daughter, Nika. Sherry and Pardis are strong advocates for philanthropical initiatives that promote health and well-being for children and underserved populations in Santa Barbara.
