That Click Didn’t Die. It Just Went Home.

Yesterday, a Philadelphia adtech company called fullthrottle.ai announced a product called Last Mile Audiences. The name is modest. The implication is not. It takes the engagement signals your brand already paid for on Google and Meta, the paid search clicks and social interactions that never turned into sales, and converts them into first-party addressable household audiences you can keep reaching across CTV, online video, audio, and direct mail.

The click you wrote off as dead has a street address now, and your brand can go knock on the door.

What it is

Last Mile Audiences is an identity play disguised as a retargeting upgrade. Here is the machinery, piece by piece.

Engagement becomes identity. fullthrottle.ai takes signals from paid search and paid social campaigns and resolves them to addressable households, not devices, not cookies, not a probabilistic blob. Those households become first-party audiences inside the fullthrottle.ai platform, which means you own them in a way you never own a Google clicker or a Meta engager.

The signal follows the person home. Once resolved, the audience can be activated across connected TV, online video, audio, and SmartMail (the company’s term for programmatic direct mail). The whole point is that the engagement no longer dies inside the channel where you bought it.

Recency windows do the targeting math for you. The launch includes rolling household windows that sort engaged households by when they last raised a hand: 0 to 30 days, 31 to 60, 61 to 90, and 91 to 120. Home services marketer? Pound the 0 to 30 day window. Selling something with a long consideration cycle? Stack several windows and let the messaging match where each cohort sits in the buying cycle.

The AI does the audience building. The audiences are automatically surfaced in the company’s Audience Library and can be recommended by its AI Media Agent as marketers build campaigns. No separate audience-building process, no list uploads, no “let me open a ticket with analytics.” The agent sees the intent and suggests the audience.

The honest framing comes from co-founder Amol Waishampayan: a click or engagement doesn’t necessarily mean someone is ready to buy at that moment. The product’s whole bet is that “not yet” is a stage, not a verdict.

What changed

For a decade, the walled gardens have run the same racket. You pay Google for the click. You pay Meta for the engagement. And then, the second the money changes hands, the person who clicked belongs to them. Your brand rents attention by the tap and owns nothing when the tap doesn’t convert. Billions of dollars of intent evaporate into someone else’s audience graph every year.

Last Mile Audiences is an attempt to intercept that signal at the identity layer and hand the keys to the advertiser. Instead of the platform keeping the engager, an independent platform turns the engagement into an addressable household and lets you keep talking to it, on the big screen in the living room, on audio, in the mailbox, for up to four months after the click.

The timing is not accidental. The Interactive Advertising Bureau projects US digital video advertising will blow past $80 billion in 2026, with CTV, online video, and social video competing for performance budgets, and it flags signal loss as an ongoing threat to targeting and measurement as AI adoption accelerates. (MarTechEdge, Oct 7, 2026) Cookies are dying, device IDs are crumbling, and every performance marketer is standing in the wreckage asking where the audience went. fullthrottle.ai’s answer: follow the click home.

And here is the part the press release will never say out loud: this is a direct attack on the walled gardens’ business model. Google and Meta’s entire moat is that engagement stays inside the walls. A tool that lets you take your paid-search intent and activate it on someone else’s CTV inventory is a jailbreak. Expect the walls to notice.

What works

The rolling recency windows are the sharpest idea in the launch, because they respect how buying actually works. Interest is not a binary state. It decays. A household that engaged 12 days ago is a hot lead with a credit card nearby; a household that engaged 110 days ago is a nurture candidate who needs a story, not a discount. Slicing those into four discrete windows and letting marketers stack them around real consideration cycles is the kind of boring-sounding feature that quietly outperforms every clever creative trick.

The AI Media Agent recommendation is the other sleeper. Audience building is the part of media planning everyone hates: the list pulls, the dedupe fights, the “is this segment stale” arguments. An agent that surfaces the audience inside the campaign workflow, pre-built and pre-qualified, removes the biggest friction in the whole funnel. The marketers who win the next five years will be the ones whose agents do the plumbing while they do the thinking.

And the cross-channel reach itself is the point. A paid search click is a lean-forward moment: somebody typed a need into a box. A CTV spot is a lean-back moment: the whole household is on the couch. Taking lean-forward intent and finishing it with lean-back reach, including the actual mailbox, is the closest thing performance marketing has to a closed loop. The click was the down payment. This is the follow-through.

What breaks or stays fenced

Now the honest part. Household-level targeting is not person-level targeting, and that distinction matters. A household that clicked your paid search ad might be a teenager researching a school project while mom actually controls the credit card. Your CTV spot hits the whole couch. Your SmartMail hits the whole address. Addressable is not the same as precise, and anyone selling household data without that caveat is selling magic beans.

Then there is the platform fence. These audiences live inside fullthrottle.ai’s platform, which means activation across CTV, video, audio, and mail runs through their pipes. You are trading one landlord for another. It is a better deal than renting from Google and owning nothing, but do not confuse “first-party” with “independent.” Your first-party data is only as portable as the platform allows.

The identity math also deserves a squint. Resolving a click to a household requires an identity graph, and every identity graph has match rates, confidence thresholds, and decay. The launch materials say nothing about match quality, and that is the number that decides whether this is a scalpel or a fog machine. Ask for it in the demo. If the vendor dances around the match rate, you have your answer.

And the structural risk: Google and Meta do not have to sit still. If enough spend flows out of their walls into addressable households, expect policy changes, signal restrictions, or outright countermeasures. The jailbreak works until the jail upgrades the locks.

Who it is for

Multi-location brands, franchises, and home services companies are the obvious fit, and that is no accident: fullthrottle.ai’s DNA is first-party data media for brands with locations, and franchise marketers are exactly the people who pay for local paid search and then lose the click to the void. If your business runs paid search across dozens or hundreds of locations and your consideration cycle is measured in weeks, not seconds, this was built for you.

The broader fit is any performance marketer spending real money on paid search and social who has accepted “they clicked but didn’t convert” as a cost of doing business. That phrase is doing a lot of heavy lifting. It is not a cost of doing business. It is a signal you paid for and then threw away.

What to do this week

1. Audit your click graveyard. Pull the last 90 days of paid search and paid social spend and segment it by “engaged but didn’t convert.” That gap is not a sunk cost. It is an audience you already paid to acquire. Price it. You will be shocked at how much money is sitting in the graveyard.

2. Build your windows around your real buying cycle. The 30/60/90/120 windows are a template, not a religion. Map your actual consideration cycle first. If your average close takes 45 days, your hot window is 0 to 45, not 0 to 30. The product lets you combine windows, so tune them to your math, not their defaults.

3. Write for the second knock, not the first impression. Creative that works on a cold audience dies on a warm one. These households already engaged. Your CTV spot and your mailer should open with recognition (“still thinking about it?”) not introduction (“hi, we’re a company”). The second touch has a completely different job than the first.

4. Measure at the household level, or don’t bother. If you activate household audiences and measure with cookie-based attribution, you will conclude it doesn’t work. Match the measurement to the targeting. Household reach needs household measurement, or you are grading a fish by its ability to climb a tree.
