Who it's for

  • D2C brands launching new SKUs that need fast qualitative signal
  • CX teams running NPS without enough open-ended response volume
  • Marketplaces and aggregators measuring vendor / product quality
  • Subscription brands monitoring satisfaction before the next renewal

How it works

  1. 1

    Trigger by purchase event

    7 days after delivery (or whatever delay fits your category), Shopify or your OMS fires a webhook to Callsy with the customer + order context.

  2. 2

    Matt asks three short questions

    "On 0–10, how likely would you recommend us?" → "Three words about the product?" → "Anything we should change?" Total call length: 90 seconds. Customers actually answer because it's not a 20-question Typeform.

  3. 3

    Tagged, categorized, routed

    Every response is transcribed, tagged by sentiment + theme (shipping, sizing, quality, packaging), and routed: 9–10 promoters get a referral SMS, 0–6 detractors get a CS callback, 7–8 passives land in your product board.

Why it works

  • Email surveys get ~5% response and skew negative (only angry customers fill them out). Voice gets 3.2× the volume and reaches happy customers too.
  • Open-ended voice answers give you the actual words customers use. Invaluable for marketing copy, product positioning, and roadmap signal.
  • Real-time sentiment tagging means detractors get human follow-up within minutes. Turning a 2-star review into a recovered customer.
  • SMS opt-in pivot: at the end of a 9 or 10 call, Matt asks "mind if I text you a referral link?". And 40% say yes.
  • Costs less than a SurveyMonkey seat once you factor in the qualitative analysis time you save.

Matt
Hi Priya, this is Matt from Boku. Quick AI-assisted call, your weighted blanket arrived last Tuesday. On 0 to 10, how likely are you to recommend us to a friend?
Customer
Probably an 8?
Matt, Callsy AI
Matt
Great. If you had to describe the blanket in three words, what would you say?
Customer
Heavy, calming, expensive.
Matt, Callsy AI
Matt
Got it. Anything you'd want us to change?
Customer
Honestly the packaging was kind of overkill. Too much plastic.
Matt, Callsy AI
Matt
Noted. That's super helpful, I'll pass it on to our packaging team. Thanks for the 90 seconds, Priya.

Frequently asked

Doesn't calling customers feel intrusive for a survey?

Not when the call is 90 seconds, branded, and respectful. Customers appreciate a brand that asks for feedback by voice. It signals you care more than the next vendor sending a Typeform.

How do you handle detractors?

Any 0–6 NPS score routes immediately to your CX team's queue with the transcript attached. Most teams call detractors back within 24 hours and convert 30%+ into promoters.

Can I export the qualitative answers to my analytics tool?

Yes. Every transcript, tag, and theme exports to your data warehouse (Snowflake, BigQuery, Postgres) or to tools like Mixpanel, Amplitude, and HubSpot via webhook.

What's the cost vs. An email survey tool?

from €49/month with 50% off launch promo. Most brands replace a €150-€500/month survey platform with Callsy and get more signal for less spend.

Can Matt run survey-specific scripts beyond NPS?

Yes. Product-feedback scripts, post-onboarding checks, churn-reason surveys, customer interviews. Anything that benefits from short, friendly voice answers instead of a form.

Meet the founders

Built by founders, not a committee.

We're Arunas and Laimonas. We started Callsy because every D2C founder we talked to was losing revenue at checkout, and email recovery had plateaued. Voice was the obvious answer. AI finally made the unit economics work. If you're in the same spot, let's talk.
