Spect

Value-based retinal screening in primary care to prevent blindness.

Vision Disease cause innumerable cases of preventable blindness globally - 415 million diabetic patients worldwide are susceptible to Diabetic Retinopathy (DR), Glaucoma, and more. Current screening protocols for vision disease require ophthalmologists to manually diagnose patients through visual assessment of the fundus. Given the large number of diabetes patients in various communities, this process is expensive, inefficient, and an undue burden on eye clinics.

Spenny is the Acorns for India. Every time a user make any digital transaction, we round off the amount to the nearest 10 INR and invest it for them into a diversified portfolio, automatically. 400M millennials in India don't invest because they don't have enough time, knowledge or access to large capital. With Spenny, they just connect the card and invest every time they spend. We're growing 67% WoW since launch, with 3,000+ users and $15,000 in AUM. Indians put $500Bn into their bank accounts annually. We charge 1.75% of the AUM for investments. That's a direct ~$9Bn market in India alone. Potentially every time a user makes a transaction, we make money. And in that sense, the timing for Spenny couldn't have been better: 1 Trillion+ transactions are expected in 2021 because of factors like Whatsapp launching its P2P payments in India for its 400M users. And the emergence of UPI means every Indian has a virtual bank account now. More interesting revenue models develop from the transaction data insights of our users. We analyse the rich data to A) up-sell more financial products like insurance etc., and B) create brand loyalty programs & partnerships. We acquire customers at minimal CAC by bank partnerships. We leverage the banks' existing users, by integrating with their mobile app. In turn, we invest into their mutual funds. Our long-term vision is to become a one-stop asset management solution for millennials.

We noticed that our users develop a productive relationship with Focus Buddy. Users stay on calls for multiple hours everyday where they depend on Focus Buddy to: • Avoid procrastination and get started: Address hidden anxieties, embrace imperfection, chunk tasks, kickstart with mini-goals, and use regular check-ins to maintain momentum. • Recover from distractions and stay focused: Focus Buddy detects when they are working on less important tasks or scrolling on social media, help them overcome the underlying concerns feeding the distraction, and help them get back to the important task • Manage stress and Prevent Burnout: Focus Buddy detects stress buildup, integrates mindfulness habits to the workflow, helps take short rejuvenating breaks, and stay composed. Our Initial ICP is people with ADHD who are highly motivated but also highly blocked by internal and environmental factors. In the future, we believe each worker should have their own personal coach that enforces proven productivity techniques in real time to help them extract more focused hours every day with the same effort.
