Dear founder,

I am writing you from a brand new PC because a few days ago I turned on my PC only to be met by a red screen of death that read — “no Operating System found.” I’m not sure how that happened, I really cannot explain it, even if I tried. But good news, I just finalized a pre-seed that budgeted for system upgrades.

The last issue explored a founders pain — this is the worst time to launch a startup. In that analysis, I leaned towards a counter argument: that there has never been a better time to launch a startup. Funds are being thrown at AI startups left, right, and center. Last week, Infinity Constellation, an AI-native holding company that builds new professional-services businesses from scratch with AI raised $24M Series A to scale operations to launch up to eight new AI-native software/services businesses per year across professional-services verticals.

Futuristic business models are being built with futuristic ideas. But ideas alone does not make a successful venture. It takes strategy, resilience, partnerships, and structure to take a startup from idea to profitable venture.

Your startup can die before you even launch if you continue to marinate on the concept of your ideas instead of executing them.

Last week I visited the University of Texas law school, where I learned of two students who'd built an app to predict TSA wait times at US airports. They picked their moment well. As I write this, the TSA wait time problem is the worst it has been in the agency's history. The partial government shutdown that began February 13 2026 has left roughly 50,000 TSA officers working without pay for months. Some airports have hit security wait times of more than four and a half hours. The TSA's own MyTSA app, ironically, has been frozen since February 17 because the agency that maintains it has no funding to update it.

That's a hot market signal. There is evidence of customer pain. There exists real urgency for a solution that eases the pain. So you have available users desperate for a solution that doesn't exist.

What Happens When The Market Conditions Change?

Strip the politics out and look at the structure of the TSA problem: There is a wait time crisis at US airports right now, but this is not a surplus passenger volume problem. This problem also has nothing to do with the upcoming World Cup. The TSA airport problem exists because Congress and the White House have not resolved a budget dispute. When that resolves — and it will, because airports cannot indefinitely run at four-hour waits without the system collapsing — the callout rates return to 4%, the lines drop to 20 minutes, and the problem disappears.

This is what a transient, policy-dependent problem looks like. Now imagine you've spent six months building a polished app to predict TSA wait times. You've raised a small round on the strength of the current crisis. You're growing users week over week because the situation is dire and your product helps. Then Congress votes or a regime change forces the shutdown to end. What happens to your business?

Some users will keep using your app. Some airports will still have peak-hour bottlenecks. Some travelers will still want to know what to expect. But the acute pain — the panicked, missing-my-flight-tomorrow desperation that was driving signups — evaporates the day the shutdown ends. You built something useful but whose value to users is dependent on a political condition you cannot control, predict, or extend. That is fragility one.

The second fragility: a giant can absorb your problem before you launch. On April 1, 2026 — while those law students were presumably still iterating — United Airlines shipped a TSA wait time tracker inside its own mobile app. United's tracker uses data the airline already collects from its own operations at its US hub airports: Chicago, Denver, Houston, Los Angeles, New York/Newark, San Francisco, and Washington DC. It shows estimated wait times for specific lanes, including PreCheck. It is, by United's framing, "first-of-its-kind" for a major US airline. As the world cup gets closer, other air lines will will follow. Within twelve months, every major US carrier will have integrated wait time data into the app that most travelers already have open on their phones at the airport. What does this do to a standalone TSA wait time app?

It does not kill it instantly. Independent apps can still serve airports the major airlines don't fly into. They can serve travelers who use multiple airlines. They can build features the airline apps won't — historical data, predictive modeling, cross-airport routing.
But it does change the math. The standalone app is now competing for attention against the app the user already has open, which already knows their flight, their gate, and their PreCheck status. The standalone app's value proposition has to be 10x better to justify a separate download. That is a much harder business than it was on the day the founders started building. That is fragility two.

This is what I call a fragile founder bet: a startup whose business model depends on conditions the founder does not control, cannot extend, and has no plan to outlast.
There are two main flavors:

Policy fragility — the pain you're solving exists because of a regulatory or political condition. When the policy changes, the pain disappears.
Displacement fragility — the pain you're solving sits in the natural feature roadmap of a larger player. When the giant ships the feature, your distinctive value collapses.

Both kill startups for the same underlying reason: the founder fell in love with the current version of the problem and stopped asking what happens when the conditions that produced it change. This is not a story about smart founders versus dumb founders or good ideas versus bad ideas. The UT law students might be doing excellent customer development. They can learn things from building this app that turn into a much bigger second company. The first version of Slack was a video game company. The first version of Twitter was a podcast platform. The first version of YouTube was a dating site. Pivots from fragile starting points are common and often productive.

What separates the founders who pivot successfully from the founders who don't? They knew their bet was fragile so they build optionality into the team, the technology, and the customer relationship. When the conditions changed, they had a second move ready. The founders who don't survive a fragility shift are the ones who didn't see it coming.

Lime, Bird, and Tier built businesses on the assumption that European cities would tolerate dockless e-scooters as a permanent micro-mobility category. In 2023, Paris held a public referendum and banned them entirely. Other cities throttled fleet sizes and capped speeds. The companies that had treated regulatory acceptance as a structural assumption rather than a fragile one watched their most profitable markets evaporate.

The Fragility Test

Before you commit to building, run your idea through five questions.

  1. Is the problem structural or transient?
    A structural problem persists across political cycles, market cycles, and technology shifts. The friction of moving money across borders is structural — it has existed in every era and gets worse, not better, as commerce globalizes. A government shutdown is transient. AI hallucinations on certain query types are transient — the foundation model providers are fixing them. Decide which kind of problem you're solving and assume nothing else.

  2. Who controls whether the problem persists?
    If the answer is "regulators," "a single agency," "one political party," "the Fed," or "a foundation model company" — that's a flag — this tells you you're building inside someone else's decision space and you need to plan accordingly.

  3. If the problem disappears tomorrow, what about your product still has value?
    This is the most important question. Identify an essential part of your software business that can survive the disappearance of the original pain point before you start building, not after.

  4. If a giant absorbs the surface problem, what unique value remains?
    For the airport app: the airline carriers will own basic wait-time display, but they will not aggregate across airlines, probably won't serve airports they don't fly into, and won't build sophisticated predictive routing across multiple security checkpoints. The standalone app has a defensible position if it leans into those gaps. If it doesn't have a defensible position, that's information to act on now.

  5. What durable customer relationship does the product create?
    Products die but relationships are forever. If you're building something where the user gives you data, gives you trust, gives you a workflow they don't want to recreate elsewhere — you have raw material for the next product. Stripe started as a payments API. The payments API created a customer relationship and a dataset. Stripe Atlas, Stripe Capital, Stripe Connect, Stripe Treasury all grew out of that relationship.

From Fragile to Agile

The strongest startups build on assumptions that compound. Stripe bet that the friction of accepting online payments was structural, not transient. That bet has only deepened in the fifteen years since its launch. Every new wave of online commerce — marketplaces, creators, AI products, cross-border SaaS — produces more demand for what Stripe sells, not less. The original problem hasn't gone away; it has expanded.

The tale of Slack is a canonical pivot story. Slack’s original product was a multiplayer online game called ‘Glitch‘ that didn't quite work. Slack originated as an internal messaging tool built by Tiny Speck while they were developing a 2D multiplayer game called Glitch. When the game was shut down in 2012, the team pivoted to focus entirely on their internal chat tool, officially launching it as a workplace communication platform in 2013

What worked was the internal chat tool the team built to talk to each other while making the game. The team kept the customer relationship — their own employees first, then early external testers — and pivoted the product. The pattern is consistent in the startup ecosystem.

For founders building today, here are three things to take from this. First, run the Fragility Test before you commit. Not after the MVP. Not after the first round. If your bet doesn't pass, start designing the second act simultaneously with the first. Second, own the relationships, not just the solution. The TSA app founders, if they're paying attention, should be capturing user emails, building a small community of frequent travelers, and learning what else those travelers struggle with at airports. When the shutdown ends and the original pain evaporates, they will still have a relationship with a defined audience of travelers — and that relationship is the asset that survives the pivot. Third, build the structural foundation early.

The startups that pivot successfully are almost always the ones whose corporate structure could accommodate the pivot. A real entity, clean cap table, IP assignment, governance posture. The startups that die quietly are the ones where the legal foundation was as improvised as the product strategy.

From Co-Pilot to Assembly

In 2020, startup founders Marlon Misra and Neil Raina launched a platform under the name Copilot that focused on creating a bespoke, white-label client portal for professional service firms, agencies, and tech-enabled businesses. Operating under Copilot.com, the company scale expanded rapidly. It was successful in capturing market share among thousands of modern consulting firms, accounting agencies, and marketing partners looking to upgrade from scattered tools like email, Slack, and QuickBooks. The initial product market fit.

In late 2022 and throughout 2023, Microsoft and GitHub heavily commercialized "Copilot" as the definitive umbrella term for their generative AI offerings. Suddenly, the startup shared its brand name with trillion-dollar tech infrastructures. Recognizing that their name was a permanent business bottleneck, the founders officially retired the "Copilot" brand name and unveiled a new name — Assembly — with product upgrades.

Their framework afforded them the leverage to pivot. Rather than portraying the change as a retreat, Assembly executed it alongside their largest growth milestone by announcing a $10M Series A funding round to fuel core tech expansion.

By dropping a name that caused endless market confusion, Assembly successfully re-established its own unique brand identity. They shifted the platform from a standard workflow aggregator into an AI-native operational hub. Today, it remains highly competitive as an all-in-one software ecosystem custom-built for professional and home-service businesses, and remains a favorite in tech stack.

Clearly, founders who build with fragile bets and fragile foundations have nothing to fall back on when the conditions change. But those who build with fragile bets and durable foundations have a real chance.

This is what Startup GPS exists to do — give you adaptive navigation through the kind of structural complexity that decides whether your startup survives changing market conditions.

The product/solution is indeed the most important asset, but the product you seek to sell is wrapped around an entity. This entity defines governance posture, a relationship to capital, a relationship to regulators, and a relationship to customers. The product can pivot. The foundation, if you got it right, will make that transition smoother.

If you're building right now on a fragile bet — and most founders are, whether they know it or not — the question the question on your mind should be: have I built a foundation that can survive a pivot? The TSA app might end up being the first chapter of a great travel-tech company. It might also end up being the thing those two law students did during a gap semester. Both outcomes are fine. The question is whether the founders are building toward the first outcome on purpose, or stumbling toward the second by accident.
