Stop bending generic survey tools to your needs
Most survey platforms try to serve everyone. eCommerce, media, market research, SaaS. The result? You inherit configuration overhead that exists for use cases you'll never touch.
Low email response rates
You need the first question right inside the email. Most tools don't let you do this.
Integrations that don't connect
Your data lives in Segment, Amplitude, Mixpanel. Their integrations point to marketing tools and CRMs you don't use.
Can't make sense of data
You collect hundreds of responses but it stays buried in spreadsheets instead of driving decisions.
Enterprise UX
Contracts, slow onboarding, buggy and ugly interface. That's sadly the state of many survey tools.
How it works
It just takes a few clicks to launch your first email survey.
Step 1: Create your survey
Start with one of our templates (NPS, CSAT, CES, churn, and more) or build your own survey. Choose colors that match your email design.
Step 2: Get your embed code
Copy the HTML code Refiner provides. When a user clicks an option in the email, their answer is automatically prefilled on the survey page. You start collecting data from the first click.
Step 3: Send with your email tool
Paste the embed code into your email marketing platform. It works with any provider that supports HTML: Customer.io, Braze, Iterable, HubSpot, and others.

Get clear insights from every response
Every response flows into dashboards built for metrics that matter to you. Filter by user segment, cohort, plan type, or custom traits. No spreadsheet gymnastics.

Automate actions based on survey responses
Connect survey responses to your existing tools. Trigger follow-ups, update user profiles, alert your team. Feedback that stays in a silo is feedback wasted.

Simple by design
Refiner is built for teams who don't have time to configure another tool. Most teams go from signup to live survey in a single session.
Hassle-free setup
"I only needed to add Refiner's SDK with a single line"
Efficient experience
"Extremely easy to set up and use, with a very intuitive interface that makes survey creation simple"
Crafted by survey experts
"Ready-to-use templates and flexible survey options make it simple to get started"
Personal customer service
"It's affordable, intuitive, and supported by a very friendly customer service team"
Yet deep when you need it
The simplicity doesn't come at the cost of power. When you need precision, the controls are there.
Brand customization
Colors, images, borders, corners, widgets (slide-in, modal and banner), and custom CSS.
Advanced targeting
Trigger surveys based on events, feature usage, lifecycle stage, or user traits. Ask the right question at the right moment.
Conditional logic
Show different questions based on previous answers. Branch into different paths for different user types.
A/B testing
Test different survey designs to see which one gets higher response rates.
Plus, AI auto-tagging & AI translation
AI translations make running multilingual surveys effortless
Qonto leveraged Refiner to overhaul their Voice of Customer Program and multiplied by 5 their NPS response rate.
We got along very well with Refiner. The way we choose our partners is important. Beyond the fact that it meets our needs and that it is a tool that also meets our budgetary constraints, there must be a real partnership of trust and continuous development.

Built for product-led companies, not everyone else
We built Refiner because most survey tools try to serve eCommerce, media, market research, and SaaS all at once. That means nothing feels built for your context.

Refiner was the only in-app survey tool that met all our requirements. Its focus on in-app surveys provides a streamlined feature set that fits our needs perfectly. We appreciate the easy integration via Google Tag Manager, allowing us to use data from our data layer and trigger surveys with GA events. Thanks to the Zapier integration, we seamlessly integrate Refiner into our automated feedback processing workflows.

With its Segment integration, Refiner makes it super easy to survey fragmented user segments easily based on properties and/or events and sync results with our data warehouse for further analysis. Setting up Refiner was a child’s play and creating new surveys is a matter of minutes. 10/10 points.
Alexander Schneekloth
Co-Founder
We love using Refiner to automatically gather NPS survey results and get critical feedback we need from our trial users so we can constantly improve our word of mouth flywheel. With its Segment and Zapier integrations it fits right into our product led growth tech stack. Easy to install, tons of value and zero hassle.
Paul Yacoubian
Founder, CEO
Refiner is a powerful in-app survey tool that allows to precisely target user segments based on our data. We tested several tools before going to Refiner and what made the big difference is that with Refiner every survey answer is directly logged into our database via Segment, and that’s a game changer! Also, the initial integration and setup were seamless and extremely easy. The templates and the ability to customize survey with our own branding and targeting specs is very much appreciated too.
Margaux Reynaud
Product Manager
We were looking for an in-app survey solution for our product that could flawlessly be synced with Segment. Refiner is the only solution we found that addresses data integrations as a main feature and not as an afterthought. Refiner is an incredibly flexible tool that can be used by nearly every team at Livestorm: growth and marketing, product, customer experience and support, and even sales.
Thibaut Davoult
Head of Growth
Refiner changed the way we operate. As a data-driven online service, we needed a way to collect feedback unintrusively at scale. Their tool helped us reach this goal in no time. Bonus : it fits super well in our growth stack (Segment, Customer.io).
Grégoire d'Aboville
Head of Growth
Refiner is the tool we were searching for to better profile our users, and gather feedback about our products. It’s very easy to set up, comes with a great UX for our users and the team is very reactive.
Javier Escribano
CPO
Super easy two-way integration with Segment and great support in setting up and launching our in-app surveys, made it a success!
Coralie Blanc
CRM Lead
We looked at various NPS solutions but Refiner was the only one which was built from the ground up to meet the needs of SaaS companies. Refiner gives us complete flexibility and their surveys match our UI/UX 100%.
Mathieu Le Roux
Voice of the Customer Manager
We discovered Refiner while using another SaaS product and we instantly fell in love with their UI / UX. So we gave it a go and were collecting user feedback for SnapShooter in no time. We are using Refiner to collect insights about how our users discovered us. The Slack notifications when someone completes a survey are a great addition to keep the team informed.
