Angie Westbrook

Angie Westbrook runs Standard AI, which uses computer vision on existing store security cameras to give brick-and-mortar retailers the kind of shopper metrics that used to exist only online.

Angie Westbrook is the CEO of Standard AI, which uses computer vision on a store's existing security cameras to bring online-style metrics to brick-and-mortar retail. Sam summed it up as Google Analytics for physical stores. The company started in checkout-free, "just walk out" retail before focusing on in-store analytics. Angie joined us in Episode 21 (November 14, 2025).

What Standard AI does

Angie's framing (10:18) is that physical retail has been a black box. Retailers mostly see sales data, which is muddied by seasonality, traffic and weather, so it is hard to tell whether a layout, display or in-store campaign is working. Running on security cameras, Standard AI tracks how shoppers move, where they look and what they engage with.

Privacy is the first thing she raised about how it works (15:17). Standard AI labels about 26 points on a person's body and turns everyone in frame into a digital stick figure. It can tell people apart but cannot identify them.

So we don't use facial recognition. There are some vendors out there that that incorporate that as part of their tech stack. It's always been a pillar of ours to be completely private.

Key ideas from the conversation

  • Leading over lagging (11:59). Angie calls herself an operations nerd. Transaction data can arrive weeks late and is a lagging signal; shopper behavior is a leading one.
  • A/B tests in weeks, not months (12:32). A typical retail test splits about 40 stores into control and experiment groups for twelve to sixteen weeks. Some Standard AI customers reached statistical significance within three weeks, sometimes with only a couple of stores. Speed also matters when a change hurts: nobody wants to wait sixteen weeks to find out.
  • A visual engagement score (16:48). Instead of inferring interest from dwell time, Standard AI measures real engagement, the in-store version of a digital impression.
  • Why new products fail (17:35). Engagement without sales points to a product or pricing problem. No engagement points to placement, signage or marketing.
  • AI makes it possible (18:55). Security footage always existed; nobody could process that much video usefully before recent computer vision breakthroughs. Next she sees predictive models that simulate store changes before anyone makes them.
But I think it's, like, more than 85, 90% of the time a new product fails, and all you do is get the sales data that says it didn't sell. Well, did it did people see it and not like it, or did they just not even have awareness of it?

most retailers that you talk to are still experiencing something like 85 to 90% of their sales are still happening inside the store.

In the news segment, Angie said she hadn't used Gamma but praised its funding news for the focus on profitability with a lean team. On ElevenLabs' iconic voice marketplace, her operator question was how consent over a person's likeness stays controlled.

What we built for the episode

Jordan built an AI retail DJ, from an idea of Sam's, with Standard AI in mind (02:56). Most stores play a generic playlist chosen with zero data. This one plays five custom AI-generated songs, from 90 BPM up to 130 and back to 100, matched to store occupancy from opening mode to a packed store to closing mode. The intro track even includes a welcome message. Jordan mentioned loving Suno for AI music but did not say which tool made these tracks.

Angie's reaction (07:21) was to test it for real: a music change may not show up in sales right away, but Standard AI could show whether upbeat music changes browsing. She suggested personalizing by aisle over time. See also our AI in retail page.

FAQ

Who is Angie Westbrook?

Angie Westbrook is the CEO of Standard AI. She describes herself as an operations nerd who preaches leading indicators over lagging ones, and she joined Built This Week in Episode 21 in November 2025.

What does Standard AI do?

Standard AI runs computer vision on a store's existing security cameras to measure what shoppers actually do, bringing online-style analytics such as A/B testing and engagement metrics to physical retail. The company started in checkout-free retail before focusing on in-store analytics.

Does Standard AI use facial recognition?

No. Angie said Standard AI labels about 26 points on a person's body to create a digital stick figure. That distinguishes people from one another and tracks movement and gaze without identifying who they are.

How fast can stores run A/B tests with Standard AI?

Angie said traditional retail tests use around 40 stores for twelve to sixteen weeks. Some Standard AI customers reached statistical significance on a change within three weeks, in some cases using only a couple of stores.

What is Standard AI's visual engagement score?

It is Standard AI's in-store equivalent of a digital impression. It measures whether shoppers actually engaged with a product or display, rather than inferring engagement from how long someone stood nearby.
