The postcard arrived after the browser tab had closed. That small sequence - browse a product online, then find a relevant piece of mail at home - contains PebblePost's whole original provocation. The company did not invent direct mail, retargeting or household data. It joined them into a product that could select an audience, generate a piece of mail, send it quickly and measure the resulting purchases with some of the discipline marketers expected from digital advertising.
Founded in New York in 2014 by Lewis Gersh, Tom Gibbons and Robert Victor, PebblePost named the category Programmatic Direct Mail. The phrase sounds like two eras bolted together, which is precisely the point. Programmatic advertising brought automated decisions and audience data; direct mail brought a physical object with a longer half-life than a banner ad. PebblePost built the machinery in between.
A decade later, the machinery matters more than the postcard. The current company describes itself as a performance-marketing business spanning Programmatic Direct Mail and Performance CTV. Its Commerce Graph pools first-party transaction signals from hundreds of brands. The Performance Marketing Engine uses those signals alongside a brand's own customer and intent data to resolve households, model audiences, run campaigns and connect exposure to online or in-store purchases.
The product is the loop
For a marketer, the visible output may be a postcard, catalog or CTV spot. The less visible product is a feedback loop. A brand supplies customer records, site activity, creative and business goals. PebblePost combines those inputs with identity and transaction signals, scores households, activates media, then checks what the exposed group bought against a holdout group that did not receive the campaign. Results feed the next round of targeting.
The household performance loop
This solves a bundle of familiar problems. Digital retargeting loses signal as browsers restrict cookies. Conventional mail can be slow, broad and difficult to optimize. CTV offers reach but often reports impressions and completion rates rather than sales. PebblePost's answer is to organize those channels around a persistent unit - the household - and a harder outcome - incremental revenue.
Its customers are growth, acquisition, retention and lifecycle teams at consumer brands. The public roster ranges across jewelry, furniture, fitness, apparel, travel and financial services: Blue Nile, Mejuri, Casper, Kendra Scott, BBQGuys, Ergatta, Lulu and Georgia, Jewelry Television and Virgin Voyages appear in its case studies or site materials. These are businesses where a purchase can occur online or in a store, and where a marketer wants more than a last click.

Transactions beat hunches
PebblePost's current differentiator is the data underneath the campaigns. The company says its Commerce Graph is powered by more than $100 billion in annual online and offline transactions, plus large volumes of real-time intent signals. Browsing shows curiosity. A transaction shows that somebody actually bought. Across many participating brands, those purchases can reveal category affinities, repeat behavior and households that resemble a brand's valuable customers.
These figures are reported by PebblePost and describe its platform or client programs; they are not independently audited results presented here.
The identity layer uses high-confidence identifiers such as postal address, email and phone to assemble dynamic household profiles. Machine-learning models then score and re-score audiences. For direct mail, the system can automate creative and route pieces toward delivery. For CTV, it can activate audiences across streaming inventory. For both, the measurement system ties exposed and control audiences back to transaction records.
That combination places PebblePost in an awkward but useful market seam. It overlaps with direct-mail platforms such as Postie and Lob, with CTV performance companies such as MNTN, with demand-side platforms such as The Trade Desk and StackAdapt, and with identity and measurement vendors. But its package is not merely software access. PebblePost also provides campaign management, onboarding, analysis and channel expertise. The business looks like a B2B platform wrapped in a managed performance service, with pricing negotiated around campaign scope and media or mail activity.
What can a brand actually do with it? An acquisition team can build lookalike audiences from its best buyers and suppress existing customers. A retention team can identify households whose purchase cadence has slowed and send a timely offer. A retailer can match a postcard to nearby store inventory. A lifecycle marketer can reinforce a web message at home without buying another display impression. The same organization can then put a CTV spot in front of similar households and compare the channels through a common measure of lift.
That breadth also clarifies when PebblePost is a poor fit. A small advertiser looking for a self-serve postcard API may prefer simpler software. A brand interested only in cheap reach may not value holdouts, identity work or managed analysis. PebblePost makes more sense when customer value is high enough to support considered targeting, when transaction data is available, and when the marketing team is willing to reserve a control group instead of claiming every sale that follows an exposure. The product asks clients to buy media and adopt a measurement habit at the same time.
From front porch to big screen
The July 2025 launch of Performance CTV was less a detour than an extension. Connected television has the same problems PebblePost had spent years learning to handle in mail: households instead of individual browser sessions, weak click signals, offline conversions and a need to prove lift. The company took the engine built for Programmatic Direct Mail and applied it to television inventory.
Performance CTV targets households using CRM, intent and transaction data, then measures online and in-store purchases. Every campaign is designed with holdout groups, according to PebblePost, so marketers can estimate what happened because of the ad rather than what merely happened after it. The company also says outside measurement providers can validate results. Blue Nile became an early reference customer, reporting that PebblePost's CTV product produced the highest incremental return among channels in an internal head-to-head test.
These numbers should be read as vendor-reported averages, not a promise. Incrementality depends on test design, customer mix, attribution windows and whether a control group was genuinely comparable. Still, the choice of metric is revealing. PebblePost wants a seat in budget discussions where a CMO must defend revenue, not just reach.
The bargain behind the graph
The strategic advantage carries a responsibility. A shared first-party data asset becomes more useful as more brands contribute signals, but that network effect only lasts if contracts, permissions, security and consumer choices are handled carefully. PebblePost calls its approach privacy-forward and employs both a general counsel and chief privacy officer. The postal household may outlive the third-party cookie as an identifier, but durability is not the same as consent. The company has to make precision feel helpful to brands without making relevance feel invasive to households.
Paper brings another obvious objection. PebblePost argues that precise programmatic targeting uses far less mail than broad traditional campaigns for comparable return. In 2023 it partnered with restoration platform veritree, promising to plant two verified trees for every tree used in its services. It also promotes FSC-certified paper. Those steps do not erase printing, production or transport, but they make the environmental claim measurable enough to inspect.
Culture appears in the company story in quieter ways. PebblePost's careers material stresses mutual respect, recognition and the freedom to be oneself. A 2024 company post said women made up more than half the organization and one-third of its C-suite at the time. Brittany Wolf, previously chief operating officer, is now listed as chief executive. The current leadership bench includes specialists in privacy, technology, product, data science, growth and people - a telling map of what it takes to run a household-data media business.
Where PebblePost goes next
The company has raised substantial capital across seed, Series A, B and C rounds, plus debt. Its 2018 Series C closed at $31 million after an extension that brought in Capital One Growth Ventures and Kickstart Seed Fund alongside Advance Venture Partners and existing backers. The supplied research brief estimates roughly 110 employees and $14.9 million in annual revenue; PebblePost itself does not publicly report current revenue or valuation.
Its opportunity is to turn a signature channel into a broader operating system for addressable household marketing. Its risk is dilution. Programmatic Direct Mail was strange enough to be memorable; “performance marketing engine” lives in a much denser field of claims. CTV adds budget and scale, but also puts PebblePost against larger platforms with deep inventory relationships and familiar buying tools.
The defensible part is the combination: collaborative transaction data, household identity, two high-attention media formats and closed-loop incrementality. If PebblePost can keep those pieces working together, marketers gain a practical way to acquire, retain and reactivate customers outside the crowded browser. A brand can reach likely buyers at home, see purchases across points of sale, compare exposed households with a control group and reallocate spending toward what created lift.
The postcard remains the company's best metaphor. It is physical but selected by software, old-fashioned but timed by live signals, quiet but measurable. The television is the new surface. The argument underneath has not changed: attention is useful; a verified purchase is better; a purchase that would not otherwise have happened is the thing worth paying for.
