Y Combinator Startup Inflow, The First Science-Based App That Helps People Manage Their ADHD, Raises $2.3M Seed 

Built by and for people with ADHD, Inflow is on a mission to help its members reach their full potential by providing affordable access to CBT-based support

NEW YORK/LONDON, JANUARY 17TH – Inflow (www.getinflow.io), the science-based app designed specifically for people with ADHD, has raised $2.3M in seed funding. 

London-based Hoxton Ventures, led the Y Combinator 21 startup’s round, with participation from US-based Route 66 Ventures. Several prominent angel investors are also backing the company, including the founders of addiction digital clinic Quit Genius (Yusuf Sherwani, Maroof Ahmed, Sarim Siddiqui), and the CEO of legal services chatbot DoNotPay, Joshua Browder.

Founded in 2020 by Seb Isaacs, Levi Epstein (formerly Product Manager at Babylon Health), and leading ADHD expert Dr. George Sachs, Inflow will use the funding to expand its team and roll out additional tools and services that have been requested from its community. 

ADHD symptoms can include anxiety, chronic boredom, impulsiveness, trouble concentrating, controlling anger, and even depression, but people with ADHD face unique challenges when trying to access support. The process often involves lengthy waiting periods — some waiting years before receiving a proper assessment — and can be prohibitively expensive. It also requires a level of self-advocacy and executive function that can prove difficult for people with ADHD. 

Built by a team of leading clinicians and coaches – with more than half of the team being neurodiverse – Inflow was created to offer a powerful alternative: a sustainable, accessible, and cost-effective solution to in-person therapy. The mobile app enables users to implement Cognitive Behavioral Therapy (CBT) coping strategies, considered part of the gold standard of ADHD care, into their daily lives. 

How The Inflow Program Works 

Inflow members can complete short daily exercises and challenges to develop healthy habits, learn skills, practice ADHD-specific mindfulness techniques, learn about their neurological differences, and reframe negative thoughts. 

The app, which combines behavioural science, clinical research and data science to create personalized experiences for its members, launched in April 2021 across the United States, and is currently being downloaded over 15k times every month. The Inflow community provides a stigma-free space in which experiences can be shared. 

“We knew we could simplify the ADHD care process and reach millions of underserved people living with ADHD, comments Inflow co-founder Seb Isaacs. “Inflow can offer immediate, affordable, and on-demand support in ways our burdened mental health system simply cannot. There’s no waitlist, no need for a referral, no complicated intake process. Inflow is here and ready whenever you are.”

Hussein Kanji, Partner at Hoxton Ventures, added:

“It’s been a privilege to watch Inflow deliver on its mission to see every person with ADHD thrive. At Hoxton Ventures, we know that empowered individuals go on to transform our world. We’re excited to see the impact that Inflow will have.”

Levi Epstein, Inflow Co-Founder and ex-Babylon Health, commented:

“Inflow, at its core, is about self-empowerment. It’s not a coincidence that we initially structured Inflow as a self-help app. We don’t consider our members ‘patients’ who are passively receiving care. They are active participants, driving their own health journey and experience.”

Jade, an Inflow member, comments:

“I thought I was beyond help and that there just weren’t any ADHD-specific strategies out there. Inflow has already given me so much of the hope that I have lost over years.”
