YC bookface is Y Combinator’s private platform for founders whose companies have been accepted into a YC batch. It brings together a founder network, discussion spaces, partner offers, investor information, and practical resources, but it is not a standalone service that founders can join independently.
What is YC Bookface used for?
YC describes Bookface as a private community for Y Combinator founders. Its role extends beyond connecting founders: it also gives members a place to exchange advice, find information, and access resources connected to building a company.
The platform includes several types of features:
- Founder and company profiles: Members can look up founders and companies in the YC network. Founders can also identify topics where they have expertise.
- Discussion spaces: Founders can post questions, seek introductions, and run polls. There are also communities organized around interests and backgrounds, including hardware, biotech, edtech, international founders, women founders, Black founders, and Hispanic and Latino founders.
- Partner offers: YC says companies in its batches can access more than $12M in credits and deals from partners such as OpenAI, Anthropic, AWS, Google Cloud, Azure, and Stripe.
- Investor information: Bookface has an investor database. A YC archived homepage described profiles and reviews for more than 50,000 startup investors, while a November 2025 podcast episode discussed founders rating their experiences with investors.
- Founder tools and materials: The landing page lists tools related to fundraising, hiring, and meeting scheduling. Founders also describe an internal knowledge base containing playbooks and templates associated with their batch.
Taken together, these features make Bookface a network and resource hub as well as a place to find investor information. Lago cofounder and YC alum Anh-Tho Chuong has described it as a knowledge base that answers 80% of the questions a founder might have.
Who can get a Bookface account?
Bookface access is tied to acceptance into a Y Combinator batch. Founders of an accepted company receive accounts, and alumni retain access after their batch ends. Startup School participation alone does not provide access, nor does submitting an application that is not accepted.
That distinction matters when you are deciding how to plan your fundraising. Bookface is a benefit associated with joining YC, not an independently available membership. If you want access, the route is to apply to a batch and be accepted. If you are not applying or do not receive acceptance, you will need to use resources available outside the private platform.
YC runs its program in winter, spring, summer, and fall. YC says it commits to its standard deal and begins the investment process on the day a company is accepted. The standard deal is $500,000. These details place Bookface in context: access comes as part of the program relationship, rather than as a separate product to purchase.
What YC information can you research publicly?
Some YC information is available without Bookface. YC’s public Founder Directory covers over 9,000 founders since 2005 and offers filters for batch, industry, region, and background. Its public Startup Directory lists over 5,000 companies.
These directories are useful for exploring companies and founders, but they are not substitutes for the private forum, member network, or full set of Bookface resources. Public information can support research; it does not grant access to private conversations or member-only features.
Round Funded also lists more than 6,200 YC companies by batch, with a reconstruction of each company’s YC application in the original form. Those reconstructions are based on public data, since YC keeps real applications private. Browse YC company profiles and application reconstructions to explore that public information.
How can you plan investor outreach without Bookface?
You do not need access to Bookface to prepare for fundraising. You can define the kind of capital you are seeking, identify investors whose focus fits your company, prepare your pitch, and keep a record of outreach and next steps. Those fundamentals apply whether you are pursuing YC or raising independently.
Round Funded helps founders find investors, send pitches, and track replies. Its catalog covers 60,000+ active VCs, angels, family offices, and accelerators. You can search by stage, industry, geography, and check size. Investor profiles are filtered to recent activity, defined as a check in roughly the last 6 months, and email addresses are verified. Explore investor matching and submit your startup.
The platform is not a replacement for Bookface’s private founder community. Instead, it supports parts of the fundraising process that do not depend on YC membership: investor discovery, pitching, and pipeline management. Round Funded also provides accelerator listings, including YC, Techstars, Antler, 500, and 100+ regional programs, matched by stage, industry, and region.
