In-app surveys that integrate with your product and data stack.
Most software companies say they listen to their users. Then they send a quarterly email survey nobody opens, dump the answers in a spreadsheet, and call it customer obsession. Refiner was built for the founders who found that embarrassing. It asks one question, to the right person, at the moment they hit friction - inside the app, while it still matters - and then routes the answer somewhere a human will actually see it.
The company is small, remote, and based in Paris. It does one thing. And it has quietly become the feedback layer for a roster of SaaS and fintech names that most startups would kill to put on a slide: Qonto, Razorpay, AutoScout24, Livestorm, Copy.ai, Shine. Refiner did it without a big funding round, without a growth team, and without ever pretending it could serve everyone.
The pitchRefiner's line for itself is plain: "in-app surveys that integrate with your product and data stack." What that hides is the strategic choice underneath it. Most survey platforms - Typeform, SurveyMonkey, and the rest - try to be everything to everyone: market research, ecommerce checkouts, event RSVPs, HR pulse checks, and product feedback all from the same box. Refiner deliberately walked away from most of that. It sells to SaaS, fintech, and marketplace teams, and it built the depth those teams need instead of the breadth a generalist needs.
That depth shows up in unglamorous places. Refiner can target a survey by user attributes, in-product behavior, device, language, or how someone answered last time. It can wait for an event - a plan upgrade, a third login, a failed action - and fire the question then, not on a calendar. And when the answer comes back, it doesn't sit still. It syncs, bi-directionally, into the customer data platforms and CRMs those teams already run on.
It is not a coincidence that the customers are the kind of companies with a real data stack. A hobby project doesn't need bi-directional Segment sync. A fintech tracking millions of monthly active users does - and that is exactly who shows up in Refiner's logo wall.
The people running Refiner day to day are product managers, growth teams, and customer success leads - the ones who have to defend a roadmap with something firmer than a hunch. The problems they bring are specific. Why do users stall on the third day of onboarding? Which segment is quietly about to churn? Is the new pricing page landing, or just loading? A generic survey tool can ask those questions. What it usually can't do is ask only the users who match, only at the right moment, and then hand the answer back to the systems where the team already lives. That gap - between collecting feedback and acting on it - is the one Refiner set out to close.
The founderRefiner is Moritz Dausinger's third act. Before it, he bootstrapped Mailparser and Docparser - two unglamorous, deeply useful B2B tools that turned emails and PDFs into structured data. He sold Mailparser in 2016 and Docparser in 2018, both to SureSwift Capital. Then, instead of retiring into advisory calls, he started building again.
The pattern is the point. Dausinger has a repeatable move: find a narrow, real B2B pain, build a focused tool for it, keep the team small, and stay independent. Refiner was born from a problem he hit himself - wanting to quickly profile the users of a SaaS app and generate insight, and finding that the existing survey tools weren't built for it. So he built the one he wanted.
There is a business lesson buried in there that plenty of over-funded startups would do well to steal: you don't need a hundred people and a Series C to own a category. You need one wedge and the discipline not to widen it. Dausinger has also been generous about the how - turning up on bootstrapper podcasts and writing about the mechanics of building small, durable software companies. The expertise isn't just in the product. It's in knowing which product not to build.
The productRefiner's surveys show up wherever the user is. Inside a web app as a contextual microsurvey. Inside a native mobile app through SDKs for iOS, Android, React Native and Flutter. In an email, on a hosted survey page, or behind a shareable link for the moments the product can't reach. The formats are the familiar ones - NPS, CSAT, CES, product-market-fit, onboarding and churn checks - but the timing and targeting are the value.
On the analysis side, Refiner leans on AI to auto-tag open-text responses into themes, so free-form feedback becomes something a roadmap can use instead of a pile of comments. It translates surveys across languages automatically. And it wires results into Slack or Microsoft Teams for alerts, into Segment and RudderStack for data flow, into Zapier for automation, and out through a REST API for anything else. The survey is the visible part. The plumbing is what keeps customers.
*57.7% is a response rate recorded in a Refiner customer case study during a beta. The lower figures are common industry benchmarks shown for context, not Refiner measurements.
Refiner charges the way SaaS teams think - by monthly active users. There's an Essentials plan around $99 a month for startups, a Growth plan from roughly $239 a month that adds event tracking, AI translations and the deeper data integrations, and a custom Enterprise tier with white-labeling and a dedicated contact. A 30-day trial runs first, and a permanent free plan capped at 25 responses a month sits underneath it.
What's notable is what isn't there. No blitzscale, no war chest. Refiner took a small early angel investment - about $200K, with Calm Company Fund among the backers - and otherwise grew on revenue. It is bootstrapped and profitable, run by a handful of people across time zones. In a market where survey startups appear and vanish on a quarterly basis, that steadiness is itself a feature.
The feedback space is loud. Survicate covers website, in-app, email and mobile, trading depth for breadth. Hotjar bundles surveys with heatmaps and session tools. Qualaroo runs lightweight nudges. Formbricks brings an open-source angle, and the giants - Typeform, SurveyMonkey, Alchemer - loom over all of it. Newer players like Screeb and Zonka keep the pressure on.
Refiner's seat in that room is the SaaS-native one. It isn't the cheapest, the broadest, or the most famous. It is the one that speaks fluent product data - behavioral targeting, event triggers, native mobile SDKs, and a two-way pipe to the data stack - which is precisely why the fintech and marketplace crowd keeps choosing it over the generalists. The positioning is narrow on purpose, and the narrowness is the moat.
The bet Refiner is making is that feedback stops being a chore when it stops being a separate step. When a churn question fires automatically, tags itself, and pings the right person in Slack, "listening to users" turns from a quarterly ritual into background infrastructure. That is a less flashy promise than most of the market makes. It is also the one that tends to survive a budget review, because the teams paying for it can point at decisions it changed.
The path hereThe through-line from 2016 to now isn't a growth curve. It's a temperament. Build something narrow and genuinely useful, charge fairly for it, keep the team small enough that everyone knows why a feature exists, and let the compounding do the work. Refiner is what that looks like applied to the unglamorous, high-value job of asking users what they think - and doing it at the exact second they have an opinion worth capturing.
