What is the curb cut effect and how does it apply to disability tech product development?
When developers solve a problem for a disabled person, the solution often benefits millions of people far beyond the original target user. Electric toothbrushes, audiobooks, OXO kitchenware, typewriters, and SMS texting all originated from or were shaped by disability communities—and later became mainstream products that transformed entire industries.
The curb cut effect works because designing for the most challenging use case forces innovation that serves everyone. When a product is engineered to work for someone with significant accessibility needs, it naturally becomes more intuitive, reliable, and user-friendly for the broader population.
As Brittany Palmer explains in this episode, this principle is driving how companies in the disability tech space approach product development. Rather than building narrowly for one user segment, they're designing for the hardest user in mind—and when that works at universal appeal, the solutions scale dramatically across business applications, robotics, law enforcement, and countless other sectors.
How universal design unlocks exponential growth
The financial opportunity here is substantial. When a disability tech solution hits broad market appeal, it doesn't just reach a niche—it explodes. The design constraints that solve accessibility challenges often become the features that differentiate a product in the mainstream market.
This is why companies building for disability communities represent such compelling investment opportunities. They're not solving edge cases—they're solving the hardest problems first, which naturally create solutions for everyone else.
"We designed for the kind of hardest user in mind, and when it hits universal appeal, it just explodes."
Brittany Palmer — Co-Founder, Adaptation Ventures. Palmer was born with a bilateral below elbow limb difference and grew up adapting to her environment without modern digital resources. She transitioned from environmental health and safety consulting to founding a disability tech company focused on equal access to travel for people with limited mobility, and now co-leads Adaptation Ventures, a pre-seed fund and investor community focused on disability, neurodivergence, accessibility, and aging.
The historical evidence is undeniable. Electric toothbrushes were developed for people with limited hand mobility, yet became standard consumer products. Audiobooks began as accessibility tools for blind and visually impaired readers, then transformed the publishing industry. SMS texting emerged as a way for deaf and hard-of-hearing people to communicate, and now it's a multi-billion-dollar channel. OXO kitchenware was designed for people with arthritis—and now it's the default ergonomic standard.
This pattern repeats because accessibility constraints force elegance. When you must make something work for someone with severe limitations, you eliminate unnecessary complexity, improve intuitive design, and create solutions that actually feel better to use—even for able-bodied users.
Why venture capital is missing this opportunity
Despite this proven pattern, only 1% of venture capital currently flows to disability-related solutions, and most of that arrives at later stages. This funding gap isn't a market failure—it's an awareness failure. Traditional investors haven't recognized that solving for disability is solving for scale.
Founders with disabilities are systematically underestimated by conventional venture capital, leaving massive market opportunities on the table. The companies that understand the curb cut effect and build accordingly aren't just creating accessible products—they're building the next generation of universal, dominant platforms.
Key takeaways
- Disability-driven product design solves the hardest problem first, creating solutions that scale universally.
- Electric toothbrushes, audiobooks, SMS texting, and OXO kitchenware all originated from disability communities and became industry standards.
- Only 1% of venture capital goes to disability tech, despite proven explosive growth potential when solutions hit mainstream appeal.
- Designing for the most constrained user eliminates unnecessary complexity and creates better products for everyone.
