--- canonical: "https://www.softatlas.io/stacks/benchmark/y-combinator-top-companies" name: "The Y Combinator Top companies stack" cohort: "Y Combinator Top companies" companies_listed: 74 companies_in_atlas: 74 benchmark_companies: 74 distinct_tools: 420 updated: "2026-10-10" --- # The Y Combinator Top companies stack ## What this measures Y Combinator's Top Companies list, the highest-valued startups among the 5,000 it has funded since 2005. Of the 74 on the list, 74 exist as a Soft Atlas organization and 74 have at least one tool identified. **Every percentage below is a share of the full 74**, including the 0 Soft Atlas has no tool for. Every figure is therefore a minimum: it can only understate how many of the cohort run a tool, never overstate it. A tool is counted for a company only when a source recorded it: a job posting naming it, a vendor listing the company as a customer, Soft Atlas market research, or an employee with a verified work email. It is counted once per company even when several sources agree. An area with no tool means Soft Atlas identified none, not that the company runs none. **Where the data comes from.** Vendors' customer references / Recent job postings / Social networks / What Soft Atlas members declare / Interviews / Companies and vendors themselves. **Minimum (never a ceiling).** Every figure is a minimum: the real share of companies using a tool can be higher, never lower. **One sub-category per tool.** Each solution is filed under one sub-category, the one of its core business, and that is where it is counted with all its customers. A suite covering several needs, say HRIS, payroll and learning, therefore appears once in a benchmark, even when its offer is broader. ## Most adopted tools 23 of 74 companies, 5 tools identified. - [Anthropic](https://www.softatlas.io/anthropic), 66% (49 companies), rated 4.9/5 on Soft Atlas (20 reviews) - Used by: Groww, Instacart, Newfront, ShipBob, Wave Mobile Money - [Amazon Web Services (AWS)](https://www.softatlas.io/amazon-web-services-inc), 61% (45 companies), rated 3.5/5 on Soft Atlas (2 reviews) - Used by: Airbnb, Bird, Faire, Presto, Scribd - [OpenAI](https://www.softatlas.io/openai), 57% (42 companies), rated 4.9/5 on Soft Atlas (4 reviews) - Used by: Airbnb, Brex, Meesho, Podium, Rigetti - [DocuSign](https://www.softatlas.io/docusign-inc), 49% (36 companies) - Used by: Brex, Dropbox, Fivetran, Flexport, Segment - [Cursor](https://www.softatlas.io/cursor), 43% (32 companies), rated 5/5 on Soft Atlas (1 review) - Used by: Amplitude, Checkr, Flock Safety, Ginkgo Bioworks, Zapier ## IT & Infrastructure 71 of 74 companies, 16 tools identified.
