Srinivas Sarkar is the co-founder and CEO of Coupl, a Y Combinator-backed neobank built for couples in India. After a stint as a management consultant at EY and a Founder in Residence run at Entrepreneur First, he set out to fix a gap he kept noticing: banking products for couples had not kept pace with how couples actually live. Coupl offers a zero-balance digital joint account that opens in under a minute and serves married, unmarried, and LGBTQ+ partners alike. The company has grown to 80,000+ couples and 300+ crore in transactions without paid advertising. Sarkar is a Forbes 30 Under 30 Asia honoree, an Entrepreneur 35 Under 35 listee, a BITS Pilani alumnus, and a three-time TEDx speaker.

Sidney Rema is the co-founder and CEO of Sanifu (YC S22), a Nairobi-based startup that uses AI to pull sales orders out of emails, WhatsApp messages, PDFs and even handwritten notes and drops them straight into ERP systems. A University of Nairobi medical student who kept building companies instead of finishing his degree, Rema spent years in small-business banking and payments before co-founding Sanifu with Phelix Juma and Bernard Momanyi. The company grew out of Patika, a marketplace the team started as a food-ordering app called MealTime, and now works with African manufacturers and distributors to cut order processing from minutes to seconds.

A Dominican operator who spent more than a decade inside Caribbean banking - including leading a 130-person team that rebuilt Scotiabank's digital platform for 2 million customers across 11 countries - he left the corner office to attack the 6% fee that immigrants pay to send money home. Pana lets people open a US bank account with just a passport, and has grown into a 'global bank on chain' blending fiat and stablecoins across 125 countries.

Backed by Y Combinator (S22), True Ventures and others with a $7M seed round, Almond pitches itself as 'One Medical for women's health,' combining in-person LA clinics with telehealth.

Ciro raised $3.8M in seed funding from CRV, Y Combinator, and SV Angel, and runs on a stack anchored by Anthropic Claude, OpenAI, and Elasticsearch. Outside the office, David self-identifies as an 'exceedingly obscure internet personality' and writes a personal blog mixing statistical deep-dives with essays on bike theft and vegetarianism.
