Origin: Sun Tzu places alliance attack as the second-highest form of strategy — superior to attacking the enemy's army and vastly superior to besieging their cities: "The highest form of generalship is to balk the enemy's plans; the next best is to prevent the junction of the enemy's forces; the next in order is to attack the enemy's army in the field; and the worst policy of all is to besiege walled cities." (Ch.3, Giles trans.) Preventing the enemy's alliances is preferable to fighting them because it wins without the cost of direct conflict.
Adopted by: The "intersecting ground" principle from Ch.11 — "On intersecting ground, join hands with your allies" — is the strategic logic behind every major platform and ecosystem play. Brandenburger & Nalebuff formalised this in Co-opetition (1996): the value net (complementors, suppliers, customers, competitors) must be actively managed, not just analysed. Doz & Hamel's Alliance Advantage (1998) is the definitive business text on building and extracting value from alliances. Microsoft's control of PC OEM relationships in the 1990s, Google's Android OEM licensing strategy, and Salesforce's AppExchange ISV program are all alliance-as-weapon executions.
Impact: In markets with strong network effects, platform economics, or distribution chokepoints, alliance position often determines outcomes more decisively than product quality. A startup with a superior product but no distribution alliances loses to an inferior product with exclusive distribution. A platform with more complementors attracts more customers regardless of native feature parity.
Why best: Most organisations treat partnerships reactively — opportunistic relationships formed when both parties see mutual benefit. Alliance strategy treats the third-party relationship landscape as a competitive battlefield to be won before the engagement begins, not a friendly environment to be navigated after.

Before building alliances, map every third party who affects the outcome of your competitive engagement:
| Role | Who they are | What they control |
|---|---|---|
| Complementors | Companies whose products increase the value of yours | Platform extensions, integrations, ecosystem |
| Distributors | Channels through which customers find and buy | Market access, customer relationships |
| Suppliers | Inputs your product depends on | Cost, quality, availability of key components |
| Standards bodies | Organisations that set the rules of the market | Technical compatibility, regulatory approval |
| Influencers | Analysts, press, communities who shape buyer perception | Customer trust, evaluation criteria |
| Key customers | Reference accounts whose adoption signals legitimacy | Social proof, market validation |
For each third party, assess: (1) How much does this relationship determine competitive outcomes? (2) Is this party currently allied with the opponent, neutral, or potentially aligned with you?
Intersecting ground — Sun Tzu's 衢地 — is territory whose control gives influence over multiple parties simultaneously. On intersecting ground, "join hands with your allies before the opponent does."
In business, intersecting ground includes:
Occupy intersecting ground before the opponent. Once a standard is established, a platform is dominant, or a reference customer is committed, displacing the occupant is expensive.
Not all alliances are equally valuable. Rank potential allies by:
Lead with the most influential, most exclusive potential allies. Winning the top-tier alliances creates a coalition that attracts further allies through association.
"Balk the enemy's plans" at the alliance level: identify which alliances the opponent is pursuing and act to prevent them before they are formalised.
Alliance prevention tactics:
When the opponent has existing alliances that disadvantage your position, apply pressure to those alliances:
Alliance disruption tactics:
Alliance advantage compounds only if alliances are maintained. The most common alliance failure is treating the partnership as a signing event rather than an ongoing relationship.
Microsoft + PC OEMs (distribution alliance as weapon, 1980s–90s): Microsoft secured preferential licensing agreements with PC OEMs that effectively made Windows the default operating system on most consumer PCs. The alliance strategy — OEM licensing at attractive terms in exchange for Windows pre-installation — occupied the distribution channel before any competitor could establish a comparable position. Apple's failure to replicate this was as decisive as any product decision.
Google Android (ecosystem coalition, 2007–2010): Google's response to Apple's closed iOS ecosystem: build an open-source Android alliance with handset manufacturers (Samsung, HTC, LG, Motorola) who had no alternative to iOS's terms. By offering manufacturers an open platform and control over hardware differentiation, Google assembled a coalition that Apple's exclusive strategy could not match. The alliance strategy produced 80%+ global smartphone market share by volume.
Startup securing the exclusive reference customer: A startup selling compliance software identifies that Company X is the most influential buyer in the vertical — their adoption will signal legitimacy to all subsequent buyers. The startup offers Company X: (1) a significantly reduced price for the first year; (2) a dedicated implementation team; (3) co-development on features specific to their use case; (4) first right of refusal on new capabilities. In exchange: a public case study, a reference call program, and a 3-year contract. The incumbent cannot offer these terms — too small a customer for their standard process. The startup occupies the reference position before the incumbent responds.
Treating alliances as bilateral deals: Alliance strategy requires a portfolio view — each alliance should contribute to a coherent coalition position, not just bilateral benefit. A portfolio of non-strategic bilateral agreements does not produce ecosystem leverage.
Announcing alliances before they are secured: Announcing a partnership in a press release before the formal agreement is signed invites the opponent to counter-offer. Secure the commitment; then announce.
Under-investing in partner success: Partners who do not succeed with your product defect or become passive references. Active partner success investment is alliance maintenance.
Assuming neutrals are available: A third party that has not committed to either side is not neutral — they are in play. Treat uncommitted high-value third parties as contested ground and move to secure their commitment.
Allying with the wrong partner at the right moment: Speed without discrimination produces alliances with low-influence partners that consume relationship capital without creating leverage. Map influence first; then move fast on the high-priority targets.
