Segment and Amplitude usually run side by side, not head to head. The real fight is quieter - which one gets to decide what an event is called before the whole company builds dashboards on top of it.

Amplitude's pricing has long punished the products that fire the most events. As those bills balloon, high-volume teams are quietly re-instrumenting on Mixpanel.

Amplitude and Mixpanel now overlap almost everywhere. The better choice starts with how your team learns: through a governed experiment loop or fast, self-serve exploration.

Pendo connects feedback to what users do inside a product. Thematic goes deeper on what customers say across surveys, tickets, calls and reviews - and the right choice depends on which blind spot costs your team more.

PostHog watches what users do inside a product. Voxco asks what people think across channels - and the useful lesson is knowing when each kind of evidence deserves the microphone.

Two products wear the onboarding label, but they solve different moments. Rocketlane organizes the human work before value arrives; Pendo helps users find value after they enter the product.

Stonly, Cast, ZapScale, Usetiful, Kaizan and Userpilot reveal how customer success is splitting into a stack of guidance, intelligence and action.

The company nobody notices - because if Whatfix is doing its job, you never read the manual. Inside the Bengaluru-and-San Jose startup teaching a billion-dollar software stack to explain itself.

Refiner, Usersnap, Simplesat, PostHog, SurveyLab and a crowd of rivals each grabbed one slice of customer feedback. The old all-in-one survey builder never saw it coming.

For a decade, tools like Pendo and Userlane told humans which accounts to save. Now Hook, Velaris and Cast are shipping the agents that do the saving, and the whole category is quietly picking a side.

SurveyMonkey, PostHog, Lyssna and a cluster of smaller rivals have built a quiet industry around one question: what do you actually think? Here is how six of them make money from your opinions, and what each does differently.

Four companies, four completely different answers to the oldest question in business - what do people actually want? We put the survey industry's odd couples side by side.

Survox, LimeSurvey, Typeform and PostHog trace a 50-year shift in how the world asks questions - from punch cards and phone banks to forms that feel like chat and surveys that pop up mid-click.
The Santa Barbara startup, built by two Amazon Alexa veterans, uses AI to read the reviews, tweets, and support tickets your product team never gets to - and tells them what to build next.

Shubham Palriwala is the co-founder and CEO of Agnost AI (YC S26), a startup building the self-improving layer for AI agents in production. A backend engineer by trade, he was the youngest engineer on Cisco's analytics team and the first hire at open-source survey company Formbricks before teaming up with childhood friend Parth Ajmera to read production AI conversations and automatically ship fixes back to the agents that generate them.
Agnost AI is a Y Combinator (S26) startup building product analytics for teams shipping conversational AI agents. It reads every production chat and voice conversation, clusters what users want, where they get stuck, and why they churn, then turns those patterns into evals, debug trails, and automatic pull requests that improve the agent. It installs in three lines of code or via an OpenTelemetry exporter, works with any LLM and framework, and processes over a million events a day for customers including Google, Exa, and Corgi.
