The Leadership Letter

Real correspondence from the people running real companies — and what it reveals about leadership.

Own Both Sides of the Market or Someone Else Will

If you control the plumbing on both the buyer and seller side, you don't just win transactions — you define the rules of the game.

Hit $1B run rate last week - business is running well, could run faster. Launched new DFP product on GOOG technology stack.

On display leapfrogging Search: Big 6 agencies driving shift to allow them to add value. What prevents this from happening? Large pubs stop participating to prevent commoditization - need to find a way to stay whole. Technology adoption by agencies.

On Project Butterfly: Yahoo selling re-targeting from Search. Can we do it? Privacy issue and lots of opportunity on Remarketing using DCLK data first (e.g. Searches for flowers). No question it brings huge value but the question is privacy and timing - want to handle same way as IBA launch. Stronger proposition to pubs than Facebook Connect.

On 5 Big Bets: Yahoo is #1 - still almost double. Is Facebook the bigger threat? They have the most impressions - He who has the most impressions wins (Eric). We are not a leader in O&O inventory (except YouTube) - We don't have a set of verticals (Auto, Tech, Finance).

Platform Metrics: Pub: 50% share, Adv: 67% share. Pub side is strategic - Atlas didn't have strong Pub-side. Having both Adv and Pub side allows more seamless integration between both - zero discrepancies vs. up to 5% discrepancies.

1. Core Message

This is a short internal status note from April 2010, written by Jag Duggal at Google. It covers four things at once: a revenue milestone, a competitive threat from display advertising overtaking search, a product idea using search data for retargeting, and a candid assessment of who Google's biggest rivals are. It reads like a pre-meeting briefing — fast, blunt, no fluff.

2. What the Executive Is Really Thinking

Duggal isn't celebrating the $1B run rate. The very next words are "could run faster." He's already looking at what's blocking growth. The note maps two types of threats: structural (publishers might pull out to avoid commoditization) and competitive (Yahoo is still double Google's size in one metric; Facebook has the most impressions). The deepest concern, though, is a quiet one: Google is not a leader in owned-and-operated inventory outside YouTube, and it lacks vertical depth in Auto, Tech, and Finance. That's a real gap. The document implies Duggal knows the platform's strength depends on fixing it.

3. Key Management Lessons

1. Owning Both Sides of a Platform Is a Structural Advantage

What it means

Duggal notes that Google holds 50% share on the publisher side and 67% on the advertiser side. He then makes a specific technical point: having both sides produces "zero discrepancies vs. up to 5% discrepancies" when only one side is covered — a direct shot at Atlas, which he says "didn't have strong Pub-side."

Why it matters

In a two-sided market, the player who sits between buyers and sellers controls the data, the pricing, and the rules. Owning only one side leaves you dependent on the other side's cooperation.

MBA Perspective

This is Platform Strategy at its clearest. A two-sided platform grows stronger as it adds participants on both sides. But the real moat is not just participation — it's the integration advantage. The "zero discrepancies" claim is a concrete switching cost: publishers and advertisers who use both sides get a cleaner, more reliable product.

Real-world application

A founder building a marketplace should ask: can I offer a meaningfully better product to sellers because I also serve buyers directly? If yes, prioritize owning both sides early, even at a cost.

2. Your Biggest Customers Can Also Be Your Biggest Threat

What it means

Duggal flags that the "Big 6 agencies" are driving a shift in display advertising that could help them "add value" — which is another way of saying they want more control. He immediately follows with: "What prevents this from happening? Large pubs stop participating to prevent commoditization."

Why it matters

When powerful intermediaries (agencies, distributors, large buyers) grow in influence, they can reshape the value chain around themselves. The platform that enables them can find itself disintermediated.

MBA Perspective

This maps directly to Porter's Five Forces — specifically, buyer power. The Big 6 agencies represent concentrated demand. When buyers are few and large, they can extract value from the platform rather than just participate in it.

Real-world application

If your top 10 customers represent 60% of revenue, they will eventually try to negotiate the rules. Build product features, data advantages, or switching costs that make leaving expensive before that conversation starts.

3. Data Assets Are Only as Valuable as the Privacy Window Allows

What it means

On Project Butterfly, Duggal identifies a clear opportunity: use DoubleClick (DCLK) search data for retargeting (example given: "Searches for flowers"). He says "no question it brings huge value" — then immediately pivots to "the question is privacy and timing."

Why it matters

Having data and being able to use it are two different things. The executive is not questioning whether the product works. He's asking whether the market and regulatory environment will allow it.

MBA Perspective

This is a Resource-Based View tension: Google holds a rare, valuable resource (cross-platform behavioral data) but its deployability is constrained by external factors. The note suggests the intent is to handle it "the same way as IBA launch" — context unclear from the document alone — implying a staged rollout as a risk management tactic.

Real-world application

Before building a product on top of a sensitive data asset, map the regulatory and user-trust constraints first. A product that works technically but gets pulled after launch is worse than a slower, compliant build.

4. 'He Who Has the Most Impressions Wins' Is a Strategic Hypothesis Worth Testing

What it means

Duggal attributes to Eric (context unclear — likely a senior executive) the view that impression volume is the key winning metric. He then notes Google is "not a leader in O&O inventory except YouTube" and lacks verticals like Auto, Tech, and Finance.

Why it matters

If you believe volume is the moat, then gaps in inventory are existential gaps — not just product gaps. The note treats this as a serious problem, not a minor one.

MBA Perspective

This reflects Network Effects and Economies of Scale logic applied to ad inventory. More impressions mean more data, more targeting precision, and more advertiser demand — a compounding loop. But it only works if the hypothesis is right. The document doesn't resolve whether impression volume alone is sufficient.

Real-world application

When your leadership team has a core strategic hypothesis ("scale wins"), pressure-test it explicitly. Name the gaps your current position leaves open and assign owners to close them. Don't let the hypothesis become invisible.

5. A Stronger Competitive Position Isn't Always the One You'd Expect

What it means

Duggal compares the retargeting idea to "Stronger proposition to pubs than Facebook Connect." He's not benchmarking against Yahoo here — he's benchmarking against Facebook's publisher product.

Why it matters

The threat framing shifts between sections of the note. Yahoo is "#1" by size. Facebook has "the most impressions." But in the retargeting comparison, the relevant competitor is Facebook Connect. Duggal is segmenting the competitive threat by product context, not treating all rivals the same.

MBA Perspective

This is sharp competitive analysis: different products face different competitors. Treating "the competition" as one monolithic group leads to bad prioritization. The right question is "who are we competing with for this specific decision by this specific customer?"

Real-world application

When pitching or positioning a new product, name the specific alternative your customer would use instead — not your company's biggest overall rival. The comparison that matters is the one the customer is actually making.

4. Strategic Analysis (MBA Style)

Competitive Strategy

Google is defending a two-sided platform while trying to extend it. The 50%/67% pub/advertiser split is a strong position, but the note identifies three pressure points: agencies gaining leverage, publishers potentially withdrawing to avoid commoditization, and Facebook and Yahoo competing for different parts of the same market. The strategy implied is integration depth (own both sides, eliminate discrepancies) plus data leverage (use DCLK search data if privacy allows).

Risk Analysis

Duggal surfaces two structural risks. First, publisher withdrawal: if large publishers stop participating to avoid being commoditized, the supply side of the platform shrinks and so does its value to advertisers. Second, data deployment risk: using search behavioral data for retargeting is valuable but carries privacy and timing constraints that could trigger regulatory or user backlash if mishandled. Both risks are acknowledged directly in the note.

Build vs Buy Analysis

The note mentions the DFP product launched on "GOOG technology stack," suggesting a prior acquisition (DoubleClick) has been integrated. The DCLK data referenced in Project Butterfly is the asset that makes retargeting possible. This implies the Buy decision — acquiring DoubleClick — is now paying off through data assets that couldn't have been built as quickly from scratch. The document doesn't address the build vs. buy question prospectively, but it shows the acquired asset being actively leveraged.

Market Dynamics

The ad tech market in 2010 (per this document) has several large players — Yahoo still dominant by one measure, Facebook growing fast in impressions, Google strong in platform share but weak in owned vertical inventory. The Big 6 agencies are a powerful intermediary layer trying to expand their own role. The note suggests the market is still being defined — no single player has locked in structural dominance.

Long-Term Strategic Implications

If Google closes the inventory gap in verticals like Auto, Tech, and Finance, and successfully integrates search behavioral data into display retargeting, the two-sided platform advantage compounds: more data, better targeting, higher advertiser ROI, more publisher revenue, harder to leave. If publishers withdraw or agencies consolidate their own platforms, Google's share on the pub side (50%) is the vulnerable number. The note implicitly treats pub-side share as the strategic priority to protect.

5. Hidden Insights

The real concern is the supply side, not the demand side. Duggal notes pub share at 50% and advertiser share at 67%. The gap is significant. In a two-sided platform, the side with lower share is the fragile side. The note's emphasis on "Large pubs stop participating" as the thing to prevent — not advertiser defection — suggests he already knows where the platform is exposed.

The impression-volume hypothesis has a silent counterargument built in. Duggal quotes the "he who has the most impressions wins" view and then immediately notes Google is not a leader in O&O inventory outside YouTube. This is either an honest gap analysis or a quiet disagreement with the hypothesis — the document doesn't resolve which. But naming the gap right after stating the hypothesis is not an accident.

Facebook is being watched on two dimensions simultaneously. As a volume threat ("most impressions") and as a publisher product competitor ("stronger proposition... than Facebook Connect"). This dual tracking of a rival — size threat and product threat — is more sophisticated than a single competitive ranking.

The privacy framing on Project Butterfly is a timing question, not a values question. Duggal says "no question it brings huge value" and frames the concern as "privacy and timing" — not whether to do it, but when and how. The reference to handling it "the same way as IBA launch" suggests a template exists for navigating this kind of rollout carefully.
