In 2023, thousands of businesses built on Twitter’s API woke up to find their access revoked or priced into oblivion. In 2024, Google’s search algorithm update wiped out traffic for sites that had built their entire acquisition strategy on SEO rankings. Every year, Apple rejects apps, Stripe freezes accounts, Amazon changes commission rates, and APIs shut down without warning.
If your entire business depends on a single platform, API, or third-party service — you are one policy change away from losing everything.

## What Dependencies Actually Look Like
A dependency is anything your business relies on that you don’t control. They come in several varieties:
**Platform dependency:** Your product exists entirely within someone else’s ecosystem. An iOS app depends on Apple’s approval. A Shopify plugin depends on Shopify’s marketplace rules. A Chrome extension depends on Google’s extension policies. These platforms can change terms, raise commissions, or reject your product at any time.
**API dependency:** Your core feature uses a third-party API. Your AI feature uses OpenAI’s API. Your payment flow uses Stripe. Your data comes from a public data source. Any of these can change pricing, rate limits, or terms.
**Distribution dependency:** You acquire customers through a single channel you don’t control. All your traffic comes from Google SEO? Algorithm changes can cut it by 80% overnight. All your customers come from one social media platform? That platform’s decline is your decline.
**Data dependency:** Your product relies on data from an external source — a government database, a third-party data provider, scraped data. Access can be revoked, data formats can change, and legal challenges can emerge.
**Infrastructure dependency:** Your entire product runs on one provider. AWS goes down? You go down. A single-region deployment means a regional outage takes you offline.

## Assessing Your Dependency Risk
Not all dependencies are equal. Assess each one on two dimensions:
**Likelihood of disruption:** How likely is this dependency to change in a way that hurts you? Mature, stable APIs (like Stripe’s) are lower risk than brand-new APIs or platforms in flux.
**Impact of disruption:** If this dependency disappeared tomorrow, what happens? Can you switch to an alternative in days? Or would your entire product stop functioning?
Map your dependencies on a 2×2 grid:
| | Low Impact | High Impact |
|—|—|—|
| **Low Likelihood** | Monitor | Plan a backup |
| **High Likelihood** | Accept it | **Urgent: Diversify NOW** |
The top-right quadrant — high likelihood AND high impact — is where existential risk lives. Any dependency there needs immediate mitigation.

## Building Resilience Into Your Architecture
You can’t eliminate dependencies entirely. But you can reduce their ability to destroy your business:
**Abstraction layers.** Don’t call third-party APIs directly throughout your codebase. Wrap them in your own interface. If OpenAI’s API changes or you want to switch to Anthropic, you update one layer instead of 50 files.
**Multi-channel acquisition.** Never rely on a single customer acquisition channel. If 80% of your customers come from one source, you’re fragile. Develop at least 2-3 independent channels. When one breaks, the others keep you alive.
**Data portability.** If your product uses third-party data, can you function (even in a degraded mode) without it? Cache what you can. Build fallbacks. Ensure your core value doesn’t vanish when an API goes down.
**Own your customer relationships.** Build a mailing list. Collect customer emails. If you’re kicked off a platform or your social media account gets suspended, can you still reach your customers directly?
**Contractual awareness.** Read the terms of service for every platform and API you depend on. Know what they’re allowed to do. “We reserve the right to change pricing at any time” means they will. Plan accordingly.

## The “What If” Exercise
For each critical dependency, complete this sentence:
“If [dependency] disappeared tomorrow, I would…”
If the answer is “be completely dead with no recovery path,” that dependency needs immediate attention.
If the answer is “have a rough week while I migrate to an alternative,” that’s manageable.
If the answer is “barely notice because I’ve built redundancy,” you’re doing it right.

## 🔨 Your Action Item: Map Your Dependencies
1. **List every third-party service, platform, API, and channel** your business relies on.
2. **For each, rate:** Likelihood of disruptive change (1-5) and Impact if it happens (1-5).
3. **Multiply the scores.** Anything above 15 is a priority risk.
4. **For your top 3 risks, write a mitigation plan:** What would you do if this dependency failed? Is there an alternative? How long would migration take? Can you build an abstraction layer now?
5. **Identify your “single point of failure.”** The one dependency that would kill your business. Make addressing it a quarterly priority.

**CTA Tip:** Dependencies are invisible until they break. And when they break, it’s always a surprise to the people who didn’t plan for it. Take 30 minutes to map every dependency your product has. Know what you rely on, and know what you’d do if it changed. Third-party platforms and API policy changes can break your business overnight — but only if you let them by not building resilience. Your business’s survival shouldn’t be in someone else’s hands.
