Product analytics shifts from dashboards to control planes

Amplitude makes the AI layer explicit

Amplitude’s fortnight was not a single launch. It was a coordinated reset of surface area. On 14 Sep it added a product page titled Build AI Workflows That Save Time and removed three existing product pages tied to AI visibility and session replay. On 17 Sep, its site navigation added Headless Amplitude while Guides and Surveys disappeared from the menu. On 21 Sep, a new Amplitude Advantage product page appeared and a healthcare industry page was removed.

The pricing page moved in the same direction. On 17 Sep, AI Agents and MCP were added to Plus, Growth and Enterprise, while inherited bundle language was removed from those higher tiers. The Free tier also changed, with 2M Events/month added and 2M Events/month forever removed. That is not cosmetic copy drift. It is packaging work around AI, headless usage and agentic interfaces.

The developer side followed. On 14 Sep, Amplitude launched repositories including AmplitudeSessionReplay-iOS, analytics-connector-ios and Amplitude-AI-Node. On 21 Sep, it introduced six more repositories, including AmplitudeStreamingAnalytics-Swift, Amplitude-MCP-Analytics-Python, amplitude-browser-sdk-gtm-template and AmplitudeSessionReplay-Android. Its browser and node analytics packages were also updated on 16 Sep. The important read is the sequence: pages, pricing, navigation and repositories all shifted within eight days.

PostHog turns breadth into governed packaging

PostHog’s centre of gravity was breadth, but the details were governance and privacy. On 14 Sep, it added 1M requests to the Free tier and removed 1500 survey responses from Free. The same day, its changelog said access control for new organisations would use the most specific rule, and mobile apps would capture push notification opens after setup.

On 18 Sep, PostHog introduced mobile replay touch capture controls so iOS, Android, Flutter and React Native apps can omit touch coordinates for privacy. The same changelog entry said AI assistants can inspect resolved member, role and default permissions for access management. That matters because product analytics suites are moving closer to operational systems, where replay, permissions and AI assistance need administrative boundaries.

The public estate was heavily reworked. On 14 Sep, PostHog added a Security Engineer careers page and five documentation pages while removing seven outdated survey-doc pages. On 18 Sep, it added three blog pages, one careers page, one comparison page, 11 documentation pages and 12 product pages, while removing three careers pages and 25 documentation pages. It also added customer logos and case-study material across Session Replay, Feature Flags, Product Analytics, CDP, Managed Warehouse and PostHog AI. The signal was not one page. It was the compression of packaging, proof and documentation into the same week.

Mixpanel buys reach, then points it at infrastructure

Mixpanel’s week had the clearest capital marker. On 18 Sep, it completed a $200m Series C led by Bain Capital Tech Opportunities. The same day, six new documentation pages appeared for real-time event streams, covering delivery, reliability, setup and monitoring, alongside product pages for permissions and the platform API.

Its release activity lined up with that more infrastructure-led posture. On 15 Sep, Mixpanel released version 1.6.0 of its iOS session replay package, adding beta wireframes and a fix to prevent event processing during exponential backoff. On 18 Sep, it released session-replay-v1.2.0 of mixpanel-flutter, again including beta wireframes and fixes. Its top repository stars rose from 1344 to 1808, and new repositories were introduced during the period.

The go-to-market layer was quieter than PostHog’s but still active. On 19 Sep, four new Google ad creatives were observed for Mixpanel, with 40 creatives running in total. Job activity was also visible: 84 postings appeared on 12 Sep, followed by smaller batches on 15 Sep and 18 Sep across roles including customer value, marketing systems, design and strategic finance. After the funding event, the visible work was less about a new category slogan and more about pipes, permissions and replay.

The developer edge is where the category is being contested

Statsig and Heap were less noisy, but their movements still fit the broader pattern. Statsig added statsig-kit on 15 Sep and terraform-provider-statsig on 18 Sep. Its @statsig/siggy package downloads rose 1540% by 20 Sep. Heap’s visible activity was narrower: on 13 Sep it published YouTube content on product analytics, session replay and HubSpot integrations, and on 16 Sep it released 0.10.0-alpha.12 of heap-swift-core-sdk.

Across the category, the noteworthy point was simultaneity. Amplitude put MCP and AI Agents into paid tiers on 17 Sep, Statsig created an infrastructure-as-code repository on 18 Sep, Mixpanel documented real-time streams and a platform API on 18 Sep, and PostHog kept shipping AI, permissions and mobile replay controls through 18 Sep and 20 Sep package updates. This was not a fortnight of dashboard feature copy. It was a fortnight of SDKs, APIs, repositories, access models and agent-facing surfaces.

That is the market’s current tell. The vendors are still selling insight, but the observed work is increasingly about where analytics sits in the stack: inside mobile apps, inside pipelines, inside permissions systems, inside agents and inside infrastructure workflows. The winners in this phase will make instrumentation feel less like reporting and more like an operating layer.
