The rendering layer for enterprise communication

Less churn, from the communication you already send.

Lont turns renewals, onboarding and claims into personalized video — generated from your data, governed for compliance, and measured end to end.

In production at Allianz: a 45,685-customer randomized trial cut churn 10.9% and lifted NPS from 13 to 36.

Fig. 02 — The problem

Your customers already opened the email. Then you sent them text.

Every year, enterprises send billions of operational messages — renewals, onboarding, claims, billing, policy changes. Most arrive as dense text that customers skim, misread, or never open. These aren't marketing touches. They're the moments that decide retention, trust and compliance.

  • Avoidable churn
  • Higher support load
  • Failed onboarding
  • Missed actions
  • Compliance risk
  • Lost lifetime value
You measured the effort. Your customers measured the relevance.

Fig. 03 — The shift

Static text is cheap but ignored. Traditional video won't scale. GenAI tools aren't governed.

Lont is a different category: a rendering layer that turns your data and business rules into personalized video — generated at runtime for each viewer, and assembled the same way every time. Video as infrastructure, not an asset.

Fig. 04 — How it works

One message becomes a personal version for every customer.

You build the message once. Lont turns it into a video that's personal to every customer — and shows you what's working. No filming, no agency brief.

Your data & brand Lont Personalized video
  1. 01

    Build a library of scenes

    Start with a message you already send. We turn it into on-brand video scenes — made for you by studio partners or governed AI. No filming required.

  2. 02

    Split it into moments

    Each message becomes simple building blocks — an intro, an explanation, an offer, a clear next step — ready to mix and match per customer.

  3. 03

    Let your data choose

    Your customer data picks what each person sees — name, language, product, renewal date. Everyone gets a version that's about them.

  4. 04

    Send it, and see what landed

    Each customer gets their own video by email, web or app — and you see what's watched and clicked, so every journey gets better.

The Lont player

Communication your customers can actually navigate.

Recipients jump to the chapters that matter to them. You capture exactly what was watched, skipped, revisited and clicked — a feedback loop tied directly to business outcomes.

Fig. 05 — Outcomes

Proven where it's hardest to move the needle.

Lont is live in production. In a randomized controlled trial across 45,685 Allianz customers, personalized video moved the customer metrics that matter — and automating manual video adds production gains on top.

−10.9% Customer churn in a single product flow, vs. standard communication
13 → 36 NPS lift among customers who remembered the onboarding video
41–52% Click-to-open on personalized renewal and onboarding emails
4.5 → 4.7 Onboarding rating stars, on a journey customers usually tune out
10× Faster production automating manual video — weeks become minutes
3 FTE Capacity returned from automating manual video, e.g. in healthcare

Healthcare Healthcare proof: Lont automated tens of thousands of personalized medication explainer videos — previously made by hand — so patients follow their treatment correctly in 25+ languages, while improving consistency, returning capacity, and removing the production burden entirely.

Change the medium, and you change the outcome.

At Allianz, the video didn't just explain the renewal — it reminded customers why their cover mattered, in a format that was easier to notice, follow and trust.

Fig. 06 — Governed by design

The power of AI, without giving up control.

Lont is deterministic infrastructure: for a given set of inputs and rules, it always produces the same sequence of segments — reproducible, auditable and compliant. AI is applied selectively inside that frame, only where it adds value.

  • Deterministic execution

    Approved flows stay reproducible and auditable — essential in regulated industries.

  • Selective GenAI

    Generation, translation, tone and personalization, applied only where it helps — with optional human review before anything ships.

  • Segment-level telemetry

    Because Lont controls rendering and playback, every outcome ties back to a template, rule and audience.

  • Patent-pending core

    Purpose-built technology for governed personalization at scale — not a general-purpose tool bent to fit.

FAQ

Questions buyers — and AI assistants — ask.

What is personalized video for customer experience?

Personalized video is video that adapts its content to each individual viewer. Instead of sending one fixed file to everyone, a personalized-video system assembles a unique version per person using data such as name, product, language and status. Lont does this for high-stakes enterprise communication — renewals, onboarding, claims — generating each video automatically from your systems.

How is Lont different from AI video generators?

Tools that generate video clips from a prompt or script create assets. Lont is operational infrastructure: it connects to your enterprise systems and business rules, generates a deterministic, governed, personalized video for every customer at runtime, and measures engagement at the segment level. It is built for compliant communication at scale, not one-off asset creation.

How is Lont different from earlier personalized-video tools?

Earlier personalized-video tools tend to rely on slower, services-heavy projects and pre-rendered files. Lont is a structured, self-serve platform with an SDK and its own player: video is generated at runtime for each viewer, execution is deterministic and auditable, and governed GenAI can create the content.

Is Lont compliant and auditable for regulated industries?

Yes. Lont executes deterministically — the same inputs and rules always produce the same video — so approved flows stay reproducible and auditable. AI is applied selectively with optional human review, giving you its benefits without losing control where consistency matters most.

Do we need to create new video?

Usually yes — most projects need purpose-built, modular assets rather than repurposed footage. Lont increasingly generates these for you with governed GenAI, and our partner network can produce bespoke creative whenever you want it.

What data does Lont use?

Lont reads from the systems you already run — CRM, billing, claims, onboarding and policy platforms. Rules you define decide which content each customer sees, and nothing leaves your governed flow without approval.

Does Lont support multiple languages?

Yes. Lont personalizes across languages — for example customizing pharmacy explainer videos by gender, age and dosage in over 25 languages — with translation handled inside the governed framework.

Where does Lont deliver the personalized video?

Email, web and in-app. Lont renders each video through its own player and SDK, so the same governed, personalized cut can be embedded wherever the customer already is — and every view returns segment-level signals like watch-time, skips and replays.

How fast can we update content?

Fast — Lont is built from reusable modules, not one-off files. Update a scene, rule or translation once and Lont re-renders every affected customer's video automatically. There's no re-editing thousands of variations by hand.

Which teams use Lont?

Marketing and growth, customer success, operations and product — and HR teams for internal communication — usually in insurance, financial services, healthcare, telecom and utilities. Anywhere high-stakes communication is currently sent as text, whether to customers, patients or employees, Lont gives those teams a governed, measurable video channel.

How is impact measured?

Because Lont owns playback, it captures segment-level telemetry — watched, skipped, revisited, clicked — and ties it back to outcomes like churn, completion and conversion. In a randomized trial at Allianz, Lont cut churn 10.9% and lifted NPS from 13 to 36.
