The full-stack lifecycle platform.
Illustrative example for Tempo, an invented productivity app: one prompt builds three emails asking free users to upgrade to Premium, each for a different kind of person, and a chat ask changes the offer to 3 months free on all three.
Illustrative example for Tempo, an invented productivity app, in JustAI's Simulation view. The Upgrade free users journey is run with 1,240 people from the segment Free users at the limit: the Content Optimizer sends each person the best of three emails (446 get “Do more in less time with Premium”, 508 get “You've outgrown the free plan”, 286 get “Everything in Tempo, unlimited”), then a two-day wait and a push. The run flags two risks in one email before anything is sent: “You've outgrown the free plan” would send fromdan.lee@gmail.com, a personal address, and its logo disappears in dark mode. A pop-out shows both problems and their fixes; both are accepted, the email sends from Tempo · hello@tempo.app with a light logo for dark mode, and the run finishes with everyone through. The rail follows 4 of them by name.
Illustrative example for airhaven, an invented stays brand: a journey for people who saved a beach stay sends an email (“Wake up to the water”), a push (“The villa you saved opened up”), an SMS, an in-app message (“Your saved villa is open”) and a landing page (“Beach stays, open this week”). Each one goes out through JustAI's own delivery layer, and a phone shows it arriving.
Illustrative example for Lumo, an invented learning app: JustAI's Journey Analytics for three live journeys. Onboarding: First lesson completed rate 27.1%, up 21.6% against the holdout, worth $13,224,316. Win-back: Subscription restarted rate 7.7%, up 46.3% against the holdout, worth $13,428,582. Black Friday: Annual plan purchased rate 7.9%, up 27.4% against the holdout, worth $17,141,991.
AI writes on-brand versions for every segment, ready to edit.
Every person gets the message that fits them.
It shifts in real time with each person's attributes and behavior.
Illustrative example. Three customers pass through the Content Optimizer on three Black Friday emails: Maya, who loves linen, gets the linen sale email; Claire, who only buys on sale, gets the biggest sale email; Daniel, who buys new arrivals, gets the Black Friday edit.
Justine remembers everything.
Every event and attribute becomes memory she acts on with each send.
Illustrative example: Justine, JustAI's agent, keeps a memory for every person. Maya: Opened the upgrade email on mobile; Daniel: Hit the project limit, second time; Claire: Team size: 12; Maya: Role: freelance designer; Daniel: Viewed the pricing page; Claire: Trial started from a referral; Maya: Clicked the focus mode push; Daniel: Calendar sync: on; Claire: Invited 4 teammates. From what she remembers she changes the journey: Maya: switched, Her email becomes a 7 AM push (Opens on mobile in the morning and answers push.); Daniel: rerouted, Moved to the Premium offer (Hit the limit twice and has looked at pricing.); Claire: deleted, Variant C, the solo-plan email (A team of 12 inviting people now; the solo pitch never fits.).
The right order, for every person.
The same emails, reordered for each person.
Illustrative example. After a new member signs up at Forge, a gym, the Sequence Optimizer orders three onboarding emails for each person: Priya, who wants a class this week, gets Book your first class first; Marcus, who trains with friends, gets Refer a friend first; Elena, who is new to the gym, gets Meet your coaches first.
Run it end to end.
Build, decide, send and measure in one place, on JustAI’s own delivery.
‘Right message, right person, right time’ was always the goal. JustAI is how we finally get there: AI tests the combinations, and we stop guessing.
Lilian GordonSenior Lifecycle Manager
Don’t have to use external reporting tools for readouts! JustAI took 1 afternoon to set up. It would have required a dev team in the past, wouldn’t have done it myself.
Vera HuiHead of CRMJustAI allowed us to rapidly scale our lifecycle experimentation without having to scale our team size.
Dillon NuanesDirector of Retention & Lifecycle
JustAI enabled our editorial team to own the process and test 10x more copy variations in just a few months than we previously managed in a six-month period.
Andrii NikitiukEng Lead
No human can pre-write a rule for every customer state. JustAI's agents don't need them.
Simon ShulmanVP MarTech
JustAI accelerated our iteration velocity with AI, and we didn't have to write a single line of code. It's like having an additional CRM Manager handling copy optimization, localization, campaign setup, and analysis.
Paulo GolovatteiCRM and LifecycleJustAI transformed how we approach copy personalization. Their collaboration helped us deliver targeted messaging, freeing our teams to focus on strategy instead of testing copy variations at scale.
Nirmal SelvarajHead of Growth EngineeringInstead of configuring A/B tests one by one in order to find the best message for our users, JustAI helped us with an always on solution to ensure message relevancy and freshness across a diverse international audience
