In Parts 1 and 2 of this series, we established why modern curb systems require a structured ecosystem rather than a consolidated vendor, and why genuine accountability, rooted in structural clarity, is the foundation of long-term program performance.
This piece examines what happens when those conditions are absent. Specifically, it examines what occurs when a vendor’s financial structure no longer aligns with a city’s program objectives, and when there is no independent voice positioned to surface the gap.
Vendors Need to Be Profitable. That’s Fine.
Vendors need to be profitable. That is not a criticism. It is a precondition for the sustained investment, staff quality, and operational reliability that cities depend on. And in well-structured relationships, profitability and client outcomes tend to move together. Vendors that perform well retain contracts, earn referrals, and build the kind of long-term partnerships that both sides value.
In a healthy multi-vendor ecosystem, partnership relationships themselves act as a check on misalignment. A vendor who acts too independently of client interests risks the relationships that sustain their business. That social and commercial accountability keeps incentives roughly aligned even without perfect contractual enforcement.
But vertical integration quietly shifts that dynamic. When a vendor controls multiple adjacent functions, like meter payment platforms and citation issuance, incentives may shift. Financial optimization increasingly serves the vendor’s own revenue model rather than the city’s outcomes. Specialist partnerships that once provided external accountability are replaced by internal business lines. The question is no longer “are we performing for the city?” It is “are we optimizing across our own platforms?” Those are different questions, and they do not always produce the same answer.
The Payment-Enforcement Feedback Loop
A vendor that controls meter payments, occupancy applications, and citation platform has a complete, real-time picture of when payments lapse, where officers are deployed, and how parkers respond to enforcement pressure. Used well, that data could serve the city's goals.
But the vertical vendor's financial interest points in a specific direction: toward meter enforcement. Meter payment apps generate transaction fees on every payment, which shape how enforcement is optimized. The result is a routing system that directs officers exclusively toward high-lapse meter blocks rather than toward violations that carry greater public consequence. Meter citations are maximized to drive payment renewals, while more serious issues like blocked bus stops, obstructed bike lanes, fire zones, and double parking are deprioritized.
The Downstream Risks Compound
Dashboards are unlikely to show whether enforcement is quietly concentrating in lower-income neighborhoods, where residents are least able to absorb the financial consequences. Meter-optimized routing deepens the equity disparities that cities are actively working to address, not by intent, but by design.
Visualizations do not show whether the city’s meter pricing is too low and should be adjusted. A vendor earning transaction fees on every payment renewal has no financial incentive to recommend rate increases that might reduce volume, even when demand-based pricing would better serve the city’s revenue and congestion goals. The city may be getting pricing advice that serves the vendor’s margin rather than its own objectives.
What remains hidden as well is the lock‑in building beneath the surface. Once enforcement routing is calibrated to meter payment data, the two systems become operationally fused. Switching either one means losing the optimization entirely. The city faces a performance cliff rather than a clean transition while the vendor holds that leverage permanently, regardless of what the contract says.
None of this requires bad intent. It is what optimization looks like when the entity doing the optimizing profits from both outcomes and no independent voice is asking whose interests are actually being served.
This is where a deep generalist plays a critical role. Not as a critic of any particular vendor, but as the presence who can surface performance trends. A deep generalist can ask the questions that a vertically integrated vendor cannot ask of itself: Is our routing serving the city's safety priorities or another's margins? Is our pricing advice reflecting the city's revenue needs or a vendor’s transaction fees? Are we building toward the city's long-term flexibility or a company’s switching cost advantage?
Those questions do not get asked from inside a vertically integrated structure.
What Good are Open Data Standards When the Door is Closed?
The Curb Data Specification (CDS), developed by the Open Mobility Foundation as a free and open standard, was built precisely to ensure that cities retain ownership of their curb data and can share it across vendors, platforms, and mobility operators in a standardized format. The standard exists because a coalition of cities, technology providers, and mobility companies understood that data sovereignty and vendor expertise matter.
But an open standard only protects what remains open. When a single vertically integrated vendor controls the payment platform, the enforcement system, and the curb management interface, CDS becomes a procedural formality rather than a meaningful safeguard. The data flows through open pipes into a closed ecosystem. The city technically owns the standard, but the vendor owns the context that makes it actionable. That is not what the standard was designed to produce.
An open ecosystem, regardless of the data standard, is more critical than a data standard that goes unused.
The Integration Window
Acquisitions are a normal feature of growing industries. Companies acquire capabilities, expand geographic reach, and bring complementary services under a single structure. Sometimes those acquisitions succeed in creating meaningful efficiencies.
But complex integrations require something that is easy to underestimate from the outside: leadership attention. Technology platforms must be aligned. Product roadmaps reconciled. Teams reorganized. Cultures merged. Client relationships reassured.
None of this is unusual; it’s the normal work required to build larger organizations. But integration cycles often last longer than people expect. In technology and services industries, they commonly span twelve to thirty-six months. During that time, leadership focus is necessarily directed inward.
Staff with deep knowledge of a city’s program intimately may be reassigned to new roles. Product priorities that served a specific use case may be deprioritized in favor of the combined entity’s broader strategy. The deep generalist advisors who built cross-disciplinary fluency over years are exactly the people most in demand internally during integration.
The Slow Risk: Organizational Drift
Over time, vertically integrated systems can drift. Innovation slows as new approaches compete internally for priority. Competitive benchmarking disappears because multiple providers are no longer operating within the system. Switching costs rise as data architecture and operational processes across disparate systems becomes tightly intertwined.
While this vertical integration drift can happen dramatically, it more often happens incrementally with the impact accumulating over time. And without the voice of a deep generalist seeking to align work with the city’s objectives, drift may go undiagnosed until it has become expensive to reverse.
A Vertically Integrated Structure Cannot Audit Itself
Part 1 introduced the concept of independent signals, insights that emerge when multiple specialized partners analyze the same infrastructure from different perspectives. Integration hubs identify failing occupancy sensors. Citation platform software flag payment apps outages. Revenue specialists surface alternative recovery strategies.
Those signals depend on structural independence. In a vertically integrated organization, the entity identifying the gap and the entity responsible for closing it are the same, with the same financial interest in how the findings are characterized. This is not a question of intent. It is a question of organizational design. Independent scrutiny requires independent structure.
This is precisely where the deep generalist advisor earns their place. Not as a critic of any particular vendor, but as the independent presence whose only financial interest is program performance. A deep generalist can ask the questions that a vertically integrated vendor cannot ask of itself:
Those questions don’t get asked from inside a vertically integrated structure. They require someone outside it.
The Procurement Paradox
Interestingly, many cities already recognize that modern parking systems require a consortium of specialized experts. This recognition often appears during procurement. Separate scopes are issued for operations, technology platforms, analytics, or revenue optimization. The work is divided intentionally, reflecting the reality that these functions are distinct disciplines.
But something curious often happens next. After dividing scope to acknowledge specialization, agencies sometimes consolidate those scopes again during the award phase, selecting a single vendor to deliver across multiple areas.
This pattern reflects a natural tension within procurement itself. On the one hand, agencies understand that complex systems benefit from specialized expertise. On the other hand, administrative simplicity encourages consolidation. Managing one contract appears easier than coordinating several.
The three-layer model highlighted in Part 1 offers a resolution to this tension. Cities do not have to choose between the administrative simplicity of a single relationship and the performance benefits of specialization. What they need is an accountable partner, one with the depth and breadth to govern a specialized ecosystem on their behalf. That partner manages the coordination complexity, so the city does not have to.
The structural simplicity offered by a deep generalist lead ensures there’s no dilution at the execution layer.
What Cities Can Do Now
The procurement processes that best protect cities from these risks are not more complex, they are more precise. Cities can strengthen evaluation frameworks by ensuring vendors are prepared to answer a clear set of questions, including the following:
Ask every vendor under evaluation to disclose any ownership, acquisition, or significant organizational change in the prior 24 months — and to describe specifically how that change affected the teams and resources serving client programs during the transition period. A vendor with genuine stability will answer directly. A vendor mid-integration will reveal, in how they answer, exactly where their attention is.
Ask where profit accountability lives. If revenues flow into the same undifferentiated ledger, the deep generalist advisor role is structurally unavailable to that vendor. Ask how the advisory function is separated from the execution functions it is supposed to evaluate.
Ask about data ownership and modular design. If switching one component of the vendor’s platform means losing the optimization that makes the others work, the city does not have a vendor relationship. It has a dependency.
These are not adversarial questions. They are the questions that a stable, self-aware vendor should be able to answer directly and confidently. The quality of the answer is itself informative.
Stable Ecosystems Outperform Everything Else
In complex systems, ecosystems tend to outperform monopolies. A well-governed ecosystem benefits from competitive tension, independent signals, and modular accountability. These structural advantages produce better outcomes than consolidation. Not because consolidation is incompetent, but because it is structurally incapable of the independent scrutiny that long-term performance requires.
And stable ecosystems, led by deep generalists, outperform ecosystems in transition.
