About us

UX deserves the same rigor as engineering.

We're building the observability layer that product teams have been quietly missing — and combining it with AI agents so insight finally moves at the speed of release.

Our mission

Make UX measurable, continuous, and actionable.

The world spent an estimated $1.4 trillion last year on cleaning up the consequences of bad UX — abandoned carts, churned users, support tickets, lawsuits. Every dollar invested in UX returns up to $100, yet most teams still treat user experience as a quarterly review item, not a daily signal.

ActiveUX was founded on a simple belief: if engineers get Datadog and PagerDuty, designers and PMs deserve the same. Continuous, prioritized, revenue-attributed signal — and a way to test the fix before users feel the bug.

— OUR THESIS

"In five years, every product team will have a UX observability platform. We're building the one they pick."

— from our seed deck, March 2025

What we believe

Three principles, every release.

01 — Insight

Signal over noise.

A list of 10,000 events is not insight. ActiveUX collapses raw data into named issues you can act on this sprint, not next quarter.

02 — Speed

Hours, not weeks.

Eight-week research cycles are out of step with weekly releases. We compress every step — recruit, run, synthesize — to the hour or under.

03 — Trust

Privacy is the product.

Mask sensitive data at the SDK. Air-gap AI agents from production. Never train on customer data. Trust is non-negotiable.

Our story

From a frustrated PM's notebook to a category.

— March 2025

Two PMs and a designer compare scars.

Founders Tony, Raymond, and Sophia had each independently watched UX research findings arrive too late to matter. They sketched the first version of ActiveUX over a weekend.

— July 2025

$4.2M seed led by Index Ventures.

Joined by angels from Hotjar, Amplitude, and Figma. Built a 6-person team and the first instrumentation SDK.

— November 2025

Closed beta with 18 design partners.

Tested the agent simulation engine against real production sites. First customer recovered $42k in cart revenue from a single regression in week one.

— February 2026

Public beta opens. 800 teams in the first month.

Launched the AI agent fleet and CI integration. Customers from FormaCraft to Northwave Banking went live in week one.

— Today

2,400+ teams. 18 ARR.

The hiring page is open. We're looking for engineers, ML researchers, designers, and a head of customer success based in NYC, London, or remote.
