As a SaaS startup begins to see success with corporate clients, it often faces a tension between rapid iteration for product-market fit (PMF) and the stability needs of its users. Which release strategies balance the company’s need for rapid iteration with clients' need for stability? This is especially true with API dependencies, where Hyrum’s Law applies: “With a sufficient number of users of an API, it does not matter what you promise in the contract: all observable behaviors of your system will be depended on by somebody.” In a recent discussion, CTOs shared best practices for managing these dual priorities, offering insights in leveraging continuous deployment, feature flags, and proactive communication to keep corporate clients satisfied while driving growth. Here’s a breakdown of actionable strategies that emerged from their experiences.

Fixed Releases vs. Continuous Deployment (CD) with Frequent, Small Releases

Several CTOs championed the benefits of continuous deployment. By deploying every commit, they argued, updates become small and manageable for users, reducing the risk of major disruptions and accelerating learning. “True continuous deployment (trunk-based dev instead of Gitflow, and every commit gets deployed right away) is more likely to reduce the issues that you brought up; while speeding up your org’s learnings,” explained CA. CA noted that smaller, more frequent releases prevent major UX disruptions and help avoid API-breaking changes that impact customer workflows.

Another CTO shared how their team approached this: “We don’t really do traditional releases. Instead, we push out small updates and features as soon as they’re ready,” explained Hugo Nogueira. He described this approach as “Fluid,” where users are continuously introduced to minor improvements without the shock of major updates.

Feature Flags: Decoupling Deployments from User Experience

Feature flags were highly recommended for managing user impact without slowing development. “Feature flags and CD—that’s all,” said KB. 

Feature flags also make it possible to “decouple code deployments from feature releases,” added CA. With feature flags, teams can deploy code anytime but only roll out visible features to specific users when ready. “You could probably have release rings for customers depending on how much stability they want,” CA suggested, advocating phased rollouts for different customer segments.

Prioritizing Backwards-Compatible APIs for Corporate Clients

Supporting backwards-compatible APIs is essential for corporate clients, who often integrate once and resist frequent updates. Several CTOs shared how their larger customers rarely update their integrations, making it crucial to keep legacy versions stable. “Once it was integrated, no matter how many new features we add, they never had the resources or the willingness to upgrade,” one CTO noted.

” We can't just decide to stop supporting old APIs. We have to assume that once APIs are deployed, they’re going to stay in use long-term. But that shouldn’t stop innovation—we can continue to push new things. Architecturally, I like to think of APIs as interfaces that don’t change from the user’s perspective, even if we update their implementation behind the scenes.” - AS

Beware of the unintended:

“Keep in mind: [Hyrum’s Law]  not limited to the published API capabilities”, - Rupert Rockinger

Even once an interface is in use, clients may start relying on even unintended functionality, which makes strong versioning a necessity.

Segmenting Product Stability Based on Feature Maturity

Rupert Rockinger proposed an approach focused on differentiating stable and evolving product areas. “If you have a number of larger customers already depending on the product to a point where they would complain about changes, you are likely [at PMF] already (at least for those personas),” he observed. By segmenting the product, companies can provide stability for well-established features while retaining the flexibility to experiment and iterate in less mature product areas.

Proactive Communication and Robust Incident Management

Multiple CTOs stressed that with continuous releases, transparent communication becomes crucial.

“For bigger, more noticeable changes (especially UX-related), we have a simple flagging system to decide if we need to communicate with users beforehand. We use feature flags for everything, and when something requires user communication, we send out a release email and only toggle the feature on after that.” - Hugo Nogueira

CA and MB suggested setting strict Service Level Agreements (SLAs) for incident resolution, noting that rapid response times are crucial to keep corporate clients satisfied. 

“Automate release notes/feature documentation (e.g., by using GitHub tags and release note generation based on issues),” recommended MB, suggesting that automation can help keep clients updated without overloading the development team with manual communication tasks.

Creating a Client Advocate Role

One additional idea emerged around helping clients navigate ongoing updates: the concept of a client advocate role. Rupert Rockinger suggested this role could support clients in adopting changes smoothly and maximizing the product’s value. A client advocate could serve as a bridge, ensuring that users remain engaged and informed despite the platform’s rapid evolution.

Conclusion

Balancing rapid innovation with the stability needs of corporate clients can be challenging, yet achievable with the right strategies. By implementing feature flags and continuous deployment, companies can control user impact and decouple deployments from user experiences. Maintaining backwards-compatible APIs allows corporate clients to rely on stable integrations without slowing down product development. Segmenting feature stability ensures that mature features remain consistent while newer areas continue to evolve. Proactive communication and robust incident management build client trust, fostering a partnership where clients feel informed and supported throughout product changes. Lastly, establishing a client advocate role can provide a personal touch, helping clients navigate and gain value from updates.

These strategies, when combined, create a release approach that not only strengthens product-market fit but also solidifies long-term client relationships.

  1. Implement feature flags and CD to control user impact and decouple deployments.

  2. Maintain backward-compatible APIs for corporate clients’ stability needs.

  3. Segment feature stability, keeping mature features consistent and innovating on newer ones.

  4. Proactively communicate release and issue updates to build client trust.

  5. Consider a customer advocate role to help clients navigate ongoing changes.
