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.

Spekter Games logo

Spekter Games

The Future of Gaming is on Super Apps. Spekter Games is a next-gen game publisher on Telegram blending Web2 and Web3 features to supercharge monetization and retention at massive scale.

Web3 features can supercharge retention, monetization, and virality, but have failed to translate to mainstream gamer adoption. Web3 games have struggled to attract mainstream gamers due to two key issues: friction in onboarding, and Web3 incentive designs that take the fun out of the games. To reduce friction, we are publishing our games on chase-based super apps such as Telegram. Telegram is massive, and they have been quietly launching features that allow us to run our games directly on Telegram, enabling seamless game distribution, payments, and crypto wallet adoption. At Spekter Games, we’re launching full-featured Web2 games on Telegram, starting with rogue-lite games. Our approach delivers top-tier gameplay that appeals to traditional gamers while keeping Web3 elements passive and seamless. The gaming industry is massive, and the opportunity to blend Web2 and Web3 the right way can be explosive. We have the right team to do this, and we are ready to lead this revolution.

Acorns for India. Every time you swipe you make a digital…

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.
