Megan Ramm spent four years selling ads that live inside an Uber ride or an Uber Eats order, ads that reach people on their way to Target, to Walmart, to a concert. She sold them to brands directly, mostly consumer packaged goods brands, and she helped build a business that went from a $500 million run rate to more than $2 billion in about three years. That is a seller's résumé. She built it at the one kind of company that owns the user, the app, the data and the checkout.

On Aug. 10, 2026, she started as global chief revenue officer of PubMatic, an independent sell-side platform that owns none of those things. PubMatic sits in the middle. It earns its money when buyers it doesn't control bid on inventory it doesn't own. In its own annual report it names The Trade Desk and Google DV360 as its largest demand sources, and at the end of June three buyers accounted for 59% of its receivables. Ramm now owns both sides of that ledger, the buyer teams and the publisher teams, across three continents. Nobody at PubMatic has held all of that before.

Ramm started in publishing, at Forbes.com and Reuters, according to every official bio she has used since. It is a common start for a certain generation of ad sales leaders: you learn what a page view is worth by trying to sell one.

Then came six years at Google. PubMatic's announcement describes that stint as search and programmatic sales. Her conference bios are more specific: she led partnerships in food, beverage and financial services. Both can be true. Google's sales model has long been organized by advertiser vertical, which means a seller there learns the client's business first and the product second.

That matters for the job she has now. A Google vertical lead sells outcomes to a brand. An SSP revenue chief has usually sold liquidity to a DSP. Those are different sales, and Ramm's education was in the first one.

Her Adweek speaker bio adds a B.S. from Miami University, continuing education at NYU, and a seat on the council of the Fresh Air Fund. She lives in New York City, and PubMatic says that is where she will be based.

The next stop was Snap Inc., where her bios say she was "an early member" of the company and led food, beverage and retail partnerships. PubMatic's release calls her an early sales leader at Snap.

Snap's early sales years were a lesson in selling something new to buyers who did not yet have a budget line for it. You had to make the category before you could take share of it. Ramm's later work at Uber followed the same pattern: brand marketers with no line item for "ride" or "delivery" media, and a sales team that had to invent the reason to buy.

The public record of her Snap years is thin. No interviews from that period surfaced, and neither Snap nor Ramm has put dates on the tenure publicly. What is on the record is how she left. In 2022, while still at Snap, she got a message from a friend at Uber Advertising, according to The Current in December 2025: "Come build with us."

By November 2022 she was on the CPG Guys podcast as head of CPG partnerships at Uber Advertising. The business she joined was small and was carrying a big promise. In February 2023, Uber chief executive Dara Khosrowshahi told investors the ad business had reached a $500 million annual run rate and said: "We are well on our way to delivering on our goal of $1 billion in advertising revenue in 2024."

Ramm sold the CEO's number. In July 2023, by then global director and head of CPG partnerships, she described the Uber pitch to Beet.TV in terms any grocery brand manager would understand: "Some CPGs come to us because they know that we can drive conversion for them on grocery and convenience."

Then the line that explains why the business grew: "We can reach you in a car when you're going to Target, to Walmart, to a concert, to an event." And: "We know the mindset that you're in."

She was candid that Uber would not build every piece itself. "We're saying, 'who is the best-in-breed that we can bring together with our offering to build as fast as we need to build to be a billion-dollar business by 2024 or 25, right?" she told Beet.TV. One of those pieces was named: "Criteo is one major partner that we're utilizing. They're best-in-breed in what they do."

Keep that quote in mind. A seller who openly plugged ad tech partners into her own platform is now running revenue at an ad tech partner. She has been the customer.

The deadline was met early. In August 2024, Uber said its ad business had reached a net revenue annual run rate of $1 billion. That October, Advertising Week New York gave her a solo session, "Unlocking Uber's Ad Power: A Conversation with Megan Ramm," billed around how the business hit $1 billion ahead of schedule.

The run rate kept climbing. With Uber's first-quarter 2025 results, the company said advertising had passed a $1.5 billion annual revenue run rate, up more than 60% year over year. Restaurant delivery advertising was approaching 2% of delivery gross bookings, a figure Uber had once called the likely ceiling.

In April 2025, Ramm moved up from head of the Americas to global head of sales. Uber's statement on the promotion: "Megan has played a pivotal role in scaling our business across more than 30 countries."

Kristi Argyilan, the former Target and Albertsons retail media chief who took over as Uber's global head of advertising in December 2024, added: "Megan's leadership will be instrumental as we continue to evolve."

Ramm's own post announcing the move read like a product roadmap: "With new products launching and more third-party partners joining us on both the demand and the supply side," she wrote, "Uber is uniquely positioned at the center of culture, commerce and connection."

By the time Uber reported fourth-quarter 2025 results in February 2026, the ad business had passed $2 billion in annualized revenue, growing more than 50%. Uber executive Balaji Krishnamurthy told analysts on that call that the old 2% ceiling no longer held: "What we are seeing is that the opportunity size here is potentially much larger." He also said "enterprise advertising is playing catch up," and the enterprise side, big brands and agencies, was where Ramm's sales team lived.

In a December 2025 interview with The Current, she was frank about the tension of building an ad business inside a consumer app: "That tension actually creates a healthy collaboration. It forces discussions about merchants and the quality of the platform that we're delivering."

On whether in-car screens put Uber against premium streamers: "We do compete with some of those premium players because of the experience." And the line that sums up her sales philosophy: "Business outcomes are the crux of customer adoption."

One footnote belongs here. Uber does not break out advertising in its earnings releases. Its first- and second-quarter 2026 releases do not mention advertising at all. Every run-rate number above was announced by Uber and is not audited as a separate line. When PubMatic's release describes Ramm as having led "a multi-billion-dollar sales organization," it is leaning on a run rate that passed $2 billion only at the end of 2025.

PubMatic did not set out to hire a seller from a closed-loop platform. It set out to fix a leadership gap.

On April 22, 2026, in the same filing where it reported preliminary first-quarter revenue of about $62.4 million, PubMatic said two senior revenue leaders were leaving. Paulina Klimenko, chief growth officer for 15 years, was stepping down to focus on her health: "The business is in a strong position, and now is the right time for me to focus on my health," she said in the release. Kyle Dozeman, chief revenue officer for the Americas, left to pursue an entrepreneurial venture and said he was "confident the team will continue to thrive."

The EMEA and APAC revenue chiefs, Emma Newman and Jason Barnes, stayed. PubMatic hired Heidrick & Struggles to find a global CRO and said it would consolidate all revenue-generating functions under that role. CEO Rajeev Goel called the changes "an opportunity to evolve our organization to best serve this transformation."

The second-quarter 10-Q fills in the rest: Klimenko's agreement ran to a July 17, 2026 separation date, with a bonus opportunity "in lieu of severance under her prior retention agreement." Ramm started three weeks later.

PubMatic's own management page shows the actual remit: publisher and buyer sales and customer success in the Americas, EMEA and APAC, excluding Commerce Media. Under the old structure those jobs sat with a growth chief and regional revenue chiefs. Now they sit with one person.

Goel's explanation in the Aug. 10 announcement was all about the buy side: "As our AI-native capabilities prove themselves with advertisers and agencies, we need a leader who can scale those relationships and capture the market opportunity ahead."

Then: "Megan is the one to lead that charge. She understands the full advertiser journey and has a proven track record of building high-performing sales organizations."

On the second-quarter earnings call, he was more specific: "Megan brings deep direct-to-brand and performance advertising expertise."

Direct-to-brand is the tell. PubMatic has been building a business that goes around the DSP when it can. Goel told analysts: "Activate enables advertisers to buy directly in our SSP." CFO Steve Pantelick added that "direct buying on Activate more than doubled year-over-year." Goel described the sales buildout this way: "as we have been growing our sales team, we've been connecting more directly with advertisers."

Pantelick said the company had "funded incremental investments in our buyer-focused sales team and broader go-to-market organization." That happened while PubMatic's total headcount shrank. The company had 1,030 employees at the end of 2025, 573 of them in India, and management said headcount was down year over year as AI and automation took on more of the work.

Ramm's own statement makes the theory explicit. "My focus is clear: bring executional rigor and a genuine commitment to delivering results for advertisers, and help drive growth that translates into stronger publisher partnerships." Advertisers come first in that sentence, and publishers benefit after. For an SSP, that order is a strategy.

She also said: "PubMatic is uniquely positioned to lead the AI transformation in digital advertising." The company is betting heavily on that. Goel says PubMatic has run more than 80 agentic campaigns, including with all five global holding companies, and he has predicted that "by the end of '28, about 25% of our ecosystem will be traded agentically."

The headline number is real. In the second quarter of 2026, PubMatic reported revenue of $78.6 million, up 11% from $71.1 million, well above its $68 million to $70 million guidance. Adjusted EBITDA rose 38% to $19.6 million. Goel called it "an important inflection point." Pantelick said: "We returned to double-digit year-over-year revenue growth ahead of schedule." The stock jumped about 20% after hours.

Here is what that growth came after.

In August 2025, PubMatic told investors that one of its top DSP partners was cutting spend. The stock fell more than 20% in a day. The company has never named the buyer. Analysts pointed to The Trade Desk, which was moving clients onto its Kokai platform at the time. A securities class action followed, alleging that PubMatic failed to tell investors that a top DSP buyer was moving clients to a platform that valued inventory differently.

It wasn't the first DSP shock. In 2024, a large DSP's switch to first-price auctions cost PubMatic about $5 million, and AdExchanger later identified that buyer as Google's DV360. Pantelick called it "a short-term phenomenon."

After the 2025 cut, revenue fell year over year for three straight quarters: $68.0 million in Q3 2025, down 5%; a slight decline in Q4; and $62.6 million in Q1 2026, down 2%. Full-year 2025 revenue was $282.9 million, down about 3%. In the first quarter of 2026, management said the business excluding that legacy DSP made up 83% of revenue. By PubMatic's own math, that one buyer still accounted for roughly 17% of revenue after the cut. That 17% is ADOTAT's estimate from the company's figures.

Now the second quarter. Pantelick said it included "several million dollars of incremental revenues from the World Cup, Amazon Prime Day and political advertising." Guidance for the third quarter is $75 million to $77 million, a step down from the quarter that was just celebrated.

And the concentration. PubMatic's 2025 annual report says it plainly: "Two of our largest DSP relationships are with Google and The Trade Desk." It also says: "A material portion of our revenue is generated through our relationship with Google and the Google DV360 DSP." In September 2025, PubMatic sued Google in federal court in Virginia for alleged monopolization of ad tech. The 10-K warns of possible retaliation.

At June 30, 2026, three buyers accounted for 29%, 15% and 15% of accounts receivable. That is 59%, up from 54% at the end of 2025. No single publisher accounts for more than 10% of revenue. The supply side is spread out. The demand side is concentrated.

Asked about the DSP that cut spend, Pantelick said: "Yeah, that is now, Barton, fully behind us." Goel said: "The relationship with the DSP remains positive and healthy." Both can be true. The relationship can be healthy, the comparison can be over, and the company can still depend on a few buyers whose product decisions it does not control. That is the seat Ramm took.

An SSP is supposed to work for publishers. It gets paid out of the publisher's take. The pitch has always been that the SSP maximizes yield for the people who own the pages and apps.

PubMatic's growth plan increasingly runs through buyers: Activate for direct buying, a buyer-focused sales team, and agentic deals with holding companies. Putting buyer sales and publisher sales under one executive is efficient. It also means one person decides, every quarter, which side gets the benefit when the two disagree.

There are already signs of the tension. On April 16, 2026, PubMatic's revised Supply Policy took effect, setting daily impression caps per publisher and an Excess Inventory Fee of $0.001 CPM for publishers that exceed them. The notice publishers received read: "Per the terms of our Supply Policy, PubMatic has set daily maximum impression limits based on traffic quality and market value." In July, PubMatic shelved its OpenWrap Web Prebid wrapper and pointed about 250 publishers to Playwire. Its VP of publisher growth solutions, John Martin, told AdExchanger that the mobile SDK it kept is "the bridge and toll booth for the mobile app ecosystem."

None of that is improper. Supply curation is what buyers have demanded from SSPs for years, and cutting excess bid requests is good for everyone's costs. But a publisher being charged for sending too much inventory and a brand being offered direct access to that same inventory are now both Ramm's customers. Her Uber experience doesn't help much here. At Uber, the publisher and the platform were the same company.

The other risk is easy to overlook. Selling directly to brands competes with your largest buyers. Every Activate dollar that skips a DSP is a dollar that The Trade Desk or DV360 might have routed through PubMatic, or might have routed elsewhere. PubMatic's 10-K already lists those two as its largest DSP relationships. Ramm has to grow the direct business without giving the two buyers that matter most a reason to send spend to someone else.

Start with what she has done. She joined an ad business that had just reached $500 million and helped take it past $2 billion, including a public $1 billion target hit ahead of schedule. She went from vertical lead to head of the Americas to global head of sales across 30-plus countries in about three years. Her bosses at Uber used words like "pivotal" and "instrumental" in public, which is easy to say and still worth something.

She also knows exactly what PubMatic wants to sell. Brands buying outcomes, not impressions. Her best-known line, "Business outcomes are the crux of customer adoption," could be the slide title for Activate. And she has sat on the other side, choosing "best-in-breed" ad tech partners to bolt onto her own platform. She knows how a buyer evaluates a vendor, because she was one.

Now what her résumé can't promise. Uber sold its own first-party inventory, with closed-loop data from impression to checkout, to brands that already used the app. PubMatic sells other people's inventory, through other companies' DSPs, in an auction it doesn't fully control. Snap, Google and Uber were all walled gardens in one form or another. PubMatic is the open web, and its revenue moves when The Trade Desk changes an algorithm or Google changes an auction.

There is no public record of Ramm running publisher relationships, supply partnerships or a DSP channel at scale. That is now half her job. She also arrived with the CFO who steadied the company through two DSP shocks, Steve Pantelick, set to retire in early 2027, and with PubMatic in litigation against one of its two largest buyers.

The bet PubMatic has made is clear. It thinks the next leg of growth comes from brands and agencies buying more directly, partly through AI agents, and that a top Uber seller can open those doors faster than an SSP lifer could. If it works, the 59% shrinks and the company becomes harder to hurt. If it doesn't, PubMatic will have reorganized its revenue team around a sales motion its largest buyers have every reason to resist.

Ramm built Uber's sales team for a platform that owned everything. PubMatic is asking her to do it for one that owns almost nothing but the auction.

This profile was reported from PubMatic's SEC filings (the 2025 Form 10-K, the second-quarter 2026 Form 10-Q and the April and August 2026 8-K releases), PubMatic and Uber earnings call remarks, Uber's public run-rate announcements, and Ramm's interviews and conference appearances from 2022 to 2026. Uber does not report advertising revenue as a separate audited line, so its run-rate figures are company statements. PubMatic does not name the DSPs behind its receivables concentration or its 2024 and 2025 revenue declines; the identification of DV360 in 2024 comes from AdExchanger, The Trade Desk attribution in 2025 comes from analysts, and the roughly 17% legacy DSP share is an ADOTAT estimate derived from PubMatic's own figures. Details of Ramm's Snap and Google tenures, including dates, are not public beyond her official bios. ADOTAT has no financial relationship with PubMatic or Megan Ramm. ADOTAT publisher Pesach Lattin has a longtime personal connection to PubMatic through ad tech contact Jeff Hirsch. PubMatic did not review this piece before publication.
