august

Perform user research, de-risk decisions and get instant feedback all within august using Digital Twins. Designed to be clones of your users, customers, visitors, buyers and prospects, Digital Twins behave and act like the real person.

What you can do

The research that used to take weeks.

Stop guessing before you launch. Show a twin your pricing, your pitch, or a half-baked idea and find out what they actually think.

De-risk decisions

Test your idea on the real person before you launch it.

Every twin is built from how real relevant people actually behave with your product. Shoppers, app users, prospects, site visitors. Run your pricing, your pitch, or a new page past them and get answers in minutes, not weeks.

Would you pay $240 for these trail shoes?
Sawyer F.
That's a hard no at $240 without more to go on. I've bought expensive trail shoes before and gotten burned. What's the actual outsole compound? Who's reviewed these on technical terrain?
Pressure-test concepts

Put one idea to a whole panel.

Ask a panel of twins the same thing at once. You understand what is working and what isn't side by side in minutes, without booking a single call.

Executive Summary

9 of 12 said they'd be down to try it. The thing that got them was how robotic the writing was. A few liked how scannable it was for that reason, though. Their real problem is how much of a spam of emails they received in the first place, not how it gets sorted or written.

Collect insights instantly

Run a survey and get answers in minutes.

Ask hundreds of digital twins the same question and watch the answers come in as they respond. What used to take weeks of fielding takes a few minutes.

How training works

Every twin is built in three layers.

  1. 1

    Interactions and behaviors are fed into our training pipeline to generate decision-making and personality weights for each individual.

  2. 2

    Each interaction generates memories, giving the twin perfect recall of what an individual has encountered.

  3. 3

    Reflections are built on top of memories, so each twin understands the individual's higher-level thinking and motivations.

FAQ

Questions product teams ask before trying august.

What is august?

August enables product teams to conduct user research with digital versions of their real users. These digital twins, as we call them, are built from real behavioral session data. You can run interviews, focus groups, and surveys with the twins built from people who actually use your product and get answers in seconds instead of weeks. Because each twin is built from what a person actually did, not what they say they'd do, it surfaces what your users really want.

How is this different from prompting a generic LLM to role-play a customer?

If you describe your user to an LLM and tell it to pretend to be them, it tends to drift toward the average, agreeable answer. An august twin is tied to one real person's behavior and remembers what they actually did through memories and reflections, so it answers the way that person's history suggests. And unlike a generic model that's wired to agree, a twin will push back if your idea doesn't hold up.

Who is august for?

Anyone who has to make a call about their product and wants to know how users will react before they commit. That usually means product managers, designers, marketers, and founders: the people who would otherwise wait weeks to recruit and schedule users, talk to randoms or LLMs, or just ship on a hunch.

Is august part of FERMÀT or separate?

August is a standalone product. The underlying digital twins technology started inside the FERMÀT commerce platform. August opens it up beyond commerce to SaaS, mobile apps, and marketing sites.

How accurate are the results?

We have multiple case studies in progress and hope to provide a validated answer soon. In the meantime, the best test is to try it with your own twins. Signup comes with free credits, so you can run a real question and see what comes back before you spend anything.

What does august compete with?

Traditional user research: the Kantar, UserTesting, Nielsen, and Listen Labs approach of asking strangers or your coworkers what your customers think. If you're paying to survey strangers, you should be talking to twins of your actual customers instead.
