Financial support from the NIH as part of their SBIR program was very much a critical component to the early start of this company [and] it continues to be a component of our success.

The NIH SBIR program has been invaluable. There'd be no other way that this would have been an option to provide to the autism community.

Litron Laboratories’ rate of innovation would not be possible without the benefit of SBIR funding.

The SBIR program is significantly important for disseminating, not just information, but actual interventions, especially for underrepresented populations.

[NIH small business funding] gave us the preliminary data that allowed us to approach investors and Big Pharma to fund the amount needed to move into phase two and phase three.

The grant gave us the funding to hire curriculum writers, to pay teachers to do pilot testing of the kits, and to go to science education conferences and present the kits; it gave us money to pay stipends for teachers who wanted to hold their own workshops, and money to provide the kits for the workshop. It really allowed the company to grow much more dramatically.

[SBIR] funding was absolutely critical to getting us off the ground.

Our very first funding came from the NIH. The origins of our success came from an NIH-funded project, and since then, we have been able to build on and expand our knowledge and tackle other pollutants.

We’re staunch supporters of this program. If anyone asks me about the NIH Small Business program, I give them nothing but encouragement to apply.

In terms of venture capitalists for minority businesses, it is a really unfair playing field. So, the fact that SBIR funds minority businesses like ours is huge because otherwise, we would not get any investments.

This funding allowed me to achieve a scientific breakthrough and now I can talk about early detection, and I can talk about cancer, fibrosis, and changing the industry.
