Balloon

Balloon is a research-backed team collaboration and decision-making platform built to eliminate groupthink and give quieter voices a psychologically safe way to contribute. Its core workflow, called a "flight," is a two-stage, partly anonymous process in which a leader poses a question, team members submit ideas ("balloons") and discuss them, and the group then evaluates and "pumps" the strongest ideas on merit, surfacing a Balloon Score that shows consensus and buy-in. Balloon ships 150+ expert-authored flight templates across 25 business areas and supports asynchronous, time-zone-independent participation, positioning itself as a replacement for status and ideation meetings (the company cites a 70% reduction in meeting time and that ~80% of information shared is new to the organization). Founded by Amanda Greenberg and Noah Bornstein, Balloon is backed by 500 Global and other investors, with an advisory board including Adam Grant, Amy Edmondson, and Daniel Pink. It is a SaaS web application (app at balloon.app) with no public developer API, OpenAPI, or developer portal at this time.

human only

More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.

Kin Score

API Evangelist profiles Balloon the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

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 — Balloon scores 17.0/100 (emerging), 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.

How we profile Balloon

Each block below is one kind of artifact we hold for Balloon. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

Security Posture 1

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
