Video production is the actual job
Avatars, text-to-speech and prompt-to-video for every team is their homepage pitch. If the job is volume of content, buy a creation suite.

Lont vs. SundaySky, honestly.
SundaySky has sold personalized video since 2006. Lont arrived much later, with a different obsession: causal proof that video moves the numbers boards care about. Which fits depends on the job you are hiring video for. Here is the difference without the spin.
The short answer.
Start from the job. If the job is producing videos (every team making content, with avatars, prompt-to-video and text-to-speech), SundaySky's creation suite is built for that, and we will not pretend to compete for it. If the job is moving a business number (renewal churn, onboarding activation, call volume), you are not buying a video tool at all; you are buying communication infrastructure that speaks in video. Lont does nothing else, and proves it the hard way: a randomized controlled trial at Allianz across 45,685 renewal customers, methodology public.
If you take one thing from this page: make both of us prove our claims the same way. The section on reading evidence below applies to every vendor, including the one writing it.
What SundaySky is.
SundaySky describes itself as the #1 enterprise video personalization platform: personalized video for every way your business grows. Its homepage emphasizes fast, pro-quality creation for every team, per-viewer tailoring, an AI suite (avatars, text-to-speech, prompt-to-video) and brand controls, with reported outcomes like an 8x digital engagement lift versus static content.
They have been at this since 2006, and the platform's polish shows it. What has stayed the same across those two decades is the pitch: engagement. If engagement with content is what you are buying, they do it well, and you should weight this page accordingly.
What Lont is.
Lont is a programmable video layer for enterprise communication. It connects to the systems you already run (policy, CRM, billing), applies rules you define, and assembles one correct video per recipient at the moments that decide the relationship: renewal, onboarding, claims, billing. Scenes are created once, under your review; from there your data decides what each customer sees, deterministically. The same record always produces the same video, and nothing changes unless you change it.
We are the newer company here, and we run like it. Personalized video has existed as a category since the mid-2000s, yet it is still a fraction of enterprise communication. We read that as an evidence gap: engagement numbers convinced teams to try video, but rarely convinced a board to make it a channel. So Lont leads with the number boards use: in a randomized controlled trial at Allianz (a randomly assigned 10% control group kept receiving the standard letter), churn fell 10.9% relative across 45,685 renewal customers, and a second randomized trial lifted onboarding NPS from 13 to 36. Methodology public, and the same measurement designed into every rollout. We have everything to prove, and we would rather chase a big, defensible number than a comfortable dashboard.

Everything in SundaySky's column comes from their own public materials as of August 2026. Verify both columns yourself; products change.
| Capability | SundaySky | Lont |
|---|---|---|
| Category, in each vendor's own words | "#1 enterprise video personalization platform" | Programmable video layer for enterprise communication |
| Published evidence | Reported customer outcomes (e.g. an 8x digital engagement lift vs. static content) | A randomized controlled trial at Allianz: churn down 10.9% across 45,685 customers, methodology public |
| Personalization, as each describes it | Real-time rendering, dynamically tailored per viewer at scale | Deterministic assembly from approved scenes, driven by your data and rules: same input, same video |
| Customer data handling | Ask how personal data flows and where it is processed | Levels up to: personal data never reaches Lont's servers (how all current healthcare customers run) |
| Multi-brand output | Brand governance controls per their materials; ask about many-label depth | Co-branded at scale: BMW, Mini, Audi, Volkswagen, Škoda, Cupra and SEAT policies plus leasing labels, each with its own terms, logo, phrasing, and visual and spoken branding |

Their side
When SundaySky is likely the better choice.
Self-serve for many teams beats depth in one journey
Their platform is built so any team can make and send video. Lont goes deep on a handful of operational journeys instead; if you need fifty teams shipping content, that is a different product.
Engagement is the brief
If the mandate is engagement with content rather than movement in an operational metric, their materials speak that language natively, and ours will keep steering you toward holdout groups.
Our side
When Lont is the better choice.
You want evidence, not engagement metrics
Our flagship result is causal: a randomized controlled trial at a named insurer, with the methodology public. We design the same trial for your first journey, so the board sees what the video caused, not what engaged viewers did anyway.
Correctness is non-negotiable
Renewal premiums, coverage terms, medication instructions: when a wrong number is an incident, deterministic assembly under your control is the architecture you want. Same record, same video, reproducibly.
Privacy posture decides the deal
Different privacy levels are possible, including setups where personal data never reaches our servers. All of our current healthcare customers run that way.
Built against Europe's harder constraints
The Allianz program ran where communication is least forgiving: several languages in one customer base, strict privacy expectations as the default, co-branded distribution through brokers and partner labels, and messaging complexity to match. Proof earned under those constraints travels well. The reverse trip is harder.
Reading the numbers
How to read the numbers, ours and theirs.
Vendor pages in this category, this one included, exist to sell. So apply the same four questions everywhere: was there a randomized control group, what was the sample size, is the customer named, and is the metric relative or absolute? An engagement lift measured between people who watched and people who did not is self-selection, not causation. And run the sanity check: if a claim implies renewal rates multiplied in a market where renewal already runs above 75%, you are reading a segment comparison, not a causal result.
Our headline number under that lens: 45,685 customers randomized, churn 12.8% in the control group against 11.4% with video, a 10.9% relative reduction over 100 days, customer named, methodology public. Hold SundaySky's numbers to the same standard, and hold ours there too.
FAQ
Lont vs. SundaySky: what buyers ask.
Is Lont a SundaySky alternative?
For operational, data-driven customer communication (renewals, onboarding, claims, billing), yes: that is exactly what Lont is built for. If what you need is broad, org-wide video creation, their suite is the more direct fit.
What is the single biggest difference?
What each vendor asks you to believe. SundaySky's public numbers are reported customer outcomes; Lont's flagship number comes from a randomized controlled trial with a control group, a named customer and public methodology. If your board will ask "how do we know the video caused this?", start from the trial.
Is Lont cheaper than SundaySky?
Neither of us publishes pricing, so we will not guess at theirs here. Put the same scenario to both of us: one journey, your real volumes, your language list, and one mid-year product change. Cost structures differ more than price points do: assembly concentrates cost in creation and keeps the per-video cost low at volume. Ask both of us for the curve, not the quote.
Can we pilot Lont alongside an existing platform?
Yes, and it is the normal way in. Keep everything running, take one journey, and run it as a randomized pilot with a holdout so the result is causal rather than anecdotal. One moment, measured properly, answers more than a full migration debate.
Why should we trust a comparison written by Lont?
Treat it as testimony, not a verdict.
