Kalinda helps class action law firms qualify potential cases in minutes with AI. The nature of class action/mass torts involves thousands of cases for a single lawsuit. For every plaintiff (injured person), law firms involved in these cases compile everything from the products they used to the injuries they have. This data is extensive, granular, and buried deep in thousands of pages of medical, financial, and employment records and others. Kalinda extracts, summarizes, and aggregates data from these records for attorneys with AI. When scaled across an entire litigation, Kalinda works tirelessly and in parallel—turning a process that once took months into just a few hours. Kalinda provides firms with the equivalent manpower of hundreds of paralegals and legal nurses, allowing them to quickly determine which claimants are eligible and helping them file faster and in greater volume.

Kamion is the Uber for Trucks for Turkey. We connect businesses that are looking for trucks, with trucks that are looking for loads. We also utilize technology to do more with fewer people and collect data.
Distributors face a shrinking workforce and rising call volume.

We help distributors scale sales output without adding headcount — by automating the work reps shouldn’t be doing in the first place.

Kestral makes it clear what your customers want most, prioritizes those tasks for highest leverage, and closes the loop with those customers. We (Brian and Bernard) have been close friends since university, and most recently worked together at Asana, leading AI and Authorization efforts. There we realized AI can completely disrupt the $50B Work Management Market, but it required a fresh start. What work we even choose to manage in the first place is critical, and the most important insights from customers are silo-ed in sales/CS while R&D gives their best shot at roadmaps meant to deliver impact. Significant requests sit in a backlog, duplicate asks flood the system, months wasted on "strategic investments". We want to bridge this gap. This message is resonating with heads of sales, heads of product, CEOs, as well as individuals, all trying to make sure the most important things get done, with less wasted effort and more revenue/retention. Kestral works by automatically take in customer data like sales call transcripts & feature request messages and a team of agents: 1. analyze them for actionable takeaways, deal blockers, and nice to haves 2. consolidate them and manage all the asks with citations 3. prioritize them by impact and frequency to cut through the noise so you can see the biggest opportunities clearly 4. connect them to your existing strategic roadmap so when the work gets done, we can automatically follow back up with your customers and win them over This is just step one of our mission to revolutionize how work gets done -- starting with what we choose to work on, and hope you follow us along for the ride!

Keylika is an early stage biopharma startup developing metal-based drugs using a platform synthesis technology to treat unmet medical needs. We then administer these drugs using proven delivery technologies to effect the best clinical outcomes. Our first product is a small molecule iron drug (new molecular entity) delivered by a wearable skin patch to treat Iron Deficiency Anemia (IDA), with significantly higher safety, efficacy and tolerability over existing treatments. This is poised to be a best-in-class, potentially breakthrough therapy for treating iron deficiency without any GI side-effects (eg. nausea, constipation, diarrhea, etc.) typically associated with oral iron supplements, and without the risks, costs and side-effects associated with IV iron infusions. When approved, Keylika’s proprietary transdermal iron will be the world's first prescription iron patch. Iron deficiency is a hugely understated problem affecting about 1.6 billion people worldwide and more than 30 million in the US alone, translating to a $17B US market.

In emerging markets like the Philippines, open finance is still nascent. Most of the population is traditionally unbanked, banking APIs don’t exist, and a borrower’s financial history lives in documents: e-wallet records, bank statements, utility bills, and more. Because this data is unstructured, credit and risk teams are forced into manual review. This slows decisioning, increases costs, and caps lending volume. Legacy OCR solutions break on noisy, real-world files and still require human verification. Kita is the first document intelligence platform built specifically for lending. We are hyperlocalized around the signals that actually drive lending outcomes in emerging and undertapped domestic markets like the Philippines, Indonesia, Mexico, and beyond. Using a layered system led by vision-language models and computer vision, we outperform traditional OCR by transforming messy borrower documents into fraud-checked, decision-ready signals lenders can use directly in underwriting. Under the hood, Kita is a learning system. We link document-level signals to repayment outcomes, allowing our models to continuously improve fraud detection and risk assessment over time. This creates a compounding advantage for lenders as their distinct underwriting decisions feed back into the system. We’re Carmel and Rhea. We met before Stanford and have been building together ever since. Carmel is from Manila, is a repeat founder, and spent three years in product at Apple. Rhea has a research background in computer vision and received the highest honor in Stanford Computer Science. Together, we combine deep local context with strong technical execution to build the infrastructure that expands access to credit in emerging markets.
