Knowtex

Making doctors 2x more efficient with AI note-taking & charge capture

We’re on a mission to leverage AI and voice technology to solve inefficiencies and revenue leakage in our healthcare system. With the rise of EHRs, the manual documentation burden on doctors has never been higher, leading to burnout and fatigue and high attrition rates. Assigning the correct diagnosis and billing codes is crucial for proper reimbursement and patient care, but medical coding is becoming more and more complex each year with growing numbers of codes (over 145,000 now), and doctors are unsupported by current technology to keep up with its ever increasing requirements. $125 billion is left on the table each year by healthcare organizations due to improper documentation and coding. Knowtex creates visit notes with up-to-date and accurate reimbursement codes from doctor-patient conversations, allowing the doctor to focus on patient care and preventing revenue leakage for hospital systems through standardized, transparent, and accurate documentation.

USDC-Smart Neobank for Latinos.

We’re building Kontigo, a USDC Smart Neobank for Latinos in the U.S. and Latin America. We launched our Peer-to-Peer onramp 20 days ago and we’ve already had $540k in deposits, 10k active users and a +300k waitlist. The founding team has built and scaled fintechs in Latam, and it’s ex-Venmo, Nubank, Rappi, MercadoLibre, Ualá, Platzi, and Yuno. We’re already backed by DST Global, Soma Capital, Pioneer Fund, Transpose + 10 YC alums. Sending money to Latin America is just as painful as holding it due to the region's fragmentation into 33 countries with 39 different currencies. On one hand, cross-border payments to Latam are absurdly expensive (up to 20% per transaction). Conversely, over the past decade, currency depreciation across the region has become unsustainable. (some countries surpassing the trillion percent ). Kontigo solves this with a USDC global wallet & a BTC savings account. - Like Venmo, but on-USDC. - Like Zelle, but for cross-border payments. No limits. - Like Nubank & Revolut, but without inflationary currencies. Bitcoin-backed. User wallets are connected to an AI-private banker on WhatsApp to execute international USDC transactions.
