Binary Thumbs
Binary Thumbs (operating name "Binary Thumb", Y Combinator Summer 2012) was a San Francisco startup founded in 2012 by Josh Leong, Michael Lin, and Matt Monson to reinvent the spreadsheet for touch devices. Its single product, Grid, was a collaborative grid-based spreadsheet and organizational app for iPad and iPhone that let people keep notes, pictures, people, and places in a freeform grid rather than rigid rows and columns. The company raised roughly $2.15M across a 2012 YC round and a 2013 seed, with participation from angel and institutional investors, and appears on the Andreessen Horowitz public investment list. Y Combinator now lists the company as inactive; Josh Leong led it as CEO from 2012 to 2016. Binary Thumb never shipped a public API, developer portal, or documentation surface -- it was a consumer iOS product company. Its lasting public technical footprint is the BinaryThumb GitHub organization and a handful of open-source React and JavaScript utility libraries published to npm.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
Binary Thumbs is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Binary Thumbs scores 5.7/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

Binary Thumbs is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.

This is an independent, third-party profile of Binary Thumbs, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
