BetweenPrompt

About

Built by people who have
seen what breaks.

BetweenPrompt was founded by security engineers and AI practitioners who watched the same pattern repeat: teams shipping AI features fast, with security as an afterthought, discovering vulnerabilities in production.

Mission

Shift security left —
all the way left.

The gap between how fast AI capabilities are being deployed and how well they are being secured is widening. Most security practices were built for a different threat model — one where the software does what it is programmed to do.

LLMs do not work that way. They are probabilistic, context-sensitive, and susceptible to adversarial inputs in ways that traditional AppSec tooling was never designed to catch. BetweenPrompt exists to close that gap.

Values

How we approach the work

Precision over volume

A single high-fidelity finding is worth more than a hundred false positives. We build tools and do work that surfaces what actually matters.

Engineers first

Security that engineers cannot act on is useless. Everything we produce — reports, tooling, guidance — is written for the people who will fix it.

Adversarial honesty

We tell you what we find, even when it is uncomfortable. Our job is to see your system the way an attacker would, and report back without softening the edges.

Standards-rooted

We map to OWASP, NIST, MITRE, and ISO not because it looks good on a report, but because those frameworks represent accumulated real-world knowledge.

We are early and selective. If you are building something interesting in AI, let us talk.
