Democracy Earth

YCombinator

Censorship resistant democracies.

Our mission is to build a sustainable democracy for the Information Age. We create censorship resistant, free and open source software that can deploy democracies anywhere there's an internet connection. We have implemented governance infrastructure for crypto networks; shadow referendums for activists in critical countries and the first Quadratic Voting implementation in the USA for the Colorado Legislative House. Backed by Templeton Foundation (2019), Y Combinator (2015) and Fast Forward (2016). Presented on TED Global (2014). Awarded by MIT Technology Review (2017) and Singularity University (2016). We did research for Alphabet, World Economic Forum and the University of Berkeley.

Denki

YCombinator

The full-stack AI financial audit firm

Automate internal auditing (planning, testing, documenting) to comply better with financial regulations. Denki performs audit work with 99% software, 1% services: ✔️ Works on existing systems (e.g. Auditboard, Workiva, ERPs) ✔️ Automates Control processes (e.g. collects evidence, runs walkthrough interviews, tests) ✔️ Records every step for traceability (workpapers w/ full audit trace) Focused on SOX programs and financial regulations (SEC Rules etc.)

Denta

YCombinator

The dental practice that runs itself

Denta is the practice management platform that puts dental practices on autopilot. When a dentist starts a new practice, instead of finding an accounting firm, hiring two front desk workers, and then spending their nights posting insurance payments, they use Denta. I started Denta to help operate my Dad's 10 practices in Iowa. In supporting those, I realized the most painful part was both people and agents having messy access to fragmented data. So I solved for that and now spend my time automating work for dentists!

Dialogus

YCombinator

Infra for enterprise voice agents.

Dialogus builds voice agent infrastructure for enterprises. Most companies can demo an AI voice agent, but getting one into production is hard. Enterprise agents need to connect to phone systems, internal tools, databases, CRMs, messaging channels, human escalation flows, monitoring, and compliance processes. Dialogus provides the infrastructure to deploy production-grade voice agents that don’t just talk but complete real workflows. Our platform lets enterprises launch agents that collect information, validate it against internal systems, update records, send follow-up messages, and escalate edge cases to humans.

Didit

YCombinator

Infrastructure for identity and fraud.

One API for KYC, KYB, AML, biometrics, and fraud — powered by 1,000+ data sources, 200+ signals, and in-house AI models. Global coverage. Integrate in minutes, pay as you go, 500 free checks/month. Start free at business.didit.me.

Digipals

YCombinator

The future of Social in the age of AI

Social networks are dead. Social media became more media than social. My friends aren't on social media anymore - it's one third ads, one third content from strangers, and one third AI slop. Our social lives are fragmented across dozens of different apps - iMessage, WhatsApp, Find My, Partiful, and Venmo. Digipals is the first AI-native social operating system that improves our relationships with friends. We built ambient AI agents that use social context from our location, calendar, and photos to take action and write code in our group chats. We are the last social platform anyone will ever need.

DiligenceSquared

YCombinator

AI-powered market due diligence for investment decisions

DiligenceSquared delivers AI-powered market due diligence for investment decisions - like the $500k McKinsey reports, but automated, auditable, and at a fraction of the cost. When Private Equity funds evaluate deals, they pay firms like McKinsey, BCG, and Bain $500K-$1M for market due diligence. The process takes weeks, and the output is a static PowerPoint that's impossible to audit. A single large-cap PE fund can spend >$30M annually on this and the total market is $10B per year. Our AI agents conduct expert interviews and synthesize insights with every claim linked to source transcripts. No black box, no "trust me" slides, and no 10x mark-up for human labor. Frederik bought these reports as a Principal at Blackstone. Soren sold them as a Principal at BCG. Harshil is a repeat founder and former Software Engineer at Google. We've seen both sides and know what matters in due diligence - and now we automate it. Our clients already include 8 leading private equity funds with over $2.4 trillion in combined AUM.

Discovered Materials

YCombinator

AI scientists to discover materials for the semiconductor industry.

We use AI to discover new materials for the semiconductor industry - specifically datacenters and fabs. Finding novel materials today takes 10+ years of lab work. We aim to compress that timeline to months, using a swarm of AI agents. Akash completed his PhD at Stanford on material discovery for semiconductors. The materials he discovered for nanoscale interconnects have been adopted into the roadmaps of Intel and TSMC. Advaith was the founding applied scientist at Persona AI (acquired by Luma Labs), where he built long horizon autonomous agents for major telecom and crypto companies. Power consumption and heat release from AI chips is doubling every year. The semiconductor industry needs new materials to keep this exponential going - Discovered Materials will help find them.

Dispatch

YCombinator

Satellites for Manufacturing in Space

Dispatch is building refurbishable reentry vehicles that host and return payloads for companies making ultra-high-value materials (semiconductors, biotech, and pharma) that can only be manufactured in space. Right now, these companies have no practical way to manufacture and get their products back to Earth. We solve this bottleneck. We just returned from the Mojave Desert testing our first full-scale reentry heat shield designed to protect the satellite as it returns from space at Mach 20+, built in an apartment for 100x cheaper than competitors. To test, we held it behind a rocket engine to simulate the forces of atmospheric reentry. IT WORKED! Watch here - https://youtu.be/dhlQmnIoptg To scale, we anchor permanent infrastructure in orbit - building high power Autonomous Space Stations designed from day one for "lights-out" manufacturing serviced by the reentry vehicles.
