Beyond conversation,
AI agents that drive action

They reach out first, see it through,
and prove it with results.

  • Messages go unopened
  • Drop off before deciding
  • Too many people to respond to
  • Can't verify follow-through

AgentMAX is an incubator

  1. Measure Action Rate
  2. Feed results back as data
  3. Smarter interventions

Action Rate: the share of users who actually act after a conversation — AgentMAX's core performance metric.

How it works

From signal to action

The agent reads the situation and moves first,
even before the user asks.

  1. STEP 1Detect signals

    Catches hesitation, stalls, and drop-off signs in real time

  2. STEP 2Pick the moment

    Chooses when the user is most likely to respond, based on their routine

  3. STEP 3Converse

    Guides the user to act with a set persuasion sequence (EDRA)

  4. STEP 4Confirm follow-through

    Checks whether the user acted and plans the next move

  5. RESULTAction & achievement

    Measures the Action Rate and refines the next intervention

Why us

Anyone can use an AI model,
but the real edge begins with data on whether people actually followed through.

Persistence data

We've tracked who kept learning and who stopped
across years of running language services.

  • What we said to win people back right before they quit
  • When re-engaging drew the strongest response

Decision data

We've recorded why sales succeeded or failed
across 15 years of consultation teams.

  • Responses that converted each type of refusal
  • When and how an offer brought the decision forward

agent max

An AI agent that speaks first and drives action

You've put it off 3 times this week.
Is the timing off?

Looking for a commuter e-bike?
A foldable, long-range
model fits best.

It's pretty chilly today.
Are you doing okay?

Calling at the time we set.
Got 10 minutes now?

Time for your lunchtime meds.
Do you have them nearby?

MAX Tutor

These conversations are recreated to show the tone of the actual service.

Trust & Control

Control stays with the user

The more an agent drives action, the more users
should decide how far and how hard it steps in.

  • Data isolation

    Personal data and business information are kept separate, and are never used to train external public models without explicit consent.

  • Set the scope

    Users decide when they can be contacted, how strong notifications are, and what data the agent may refer to — and can change these at any time.

  • Approval for what matters

    Routine guidance runs on its own, but high-stakes actions like payments and contracts require the user's approval.

“AI가 먼저 전화 건다”…위버스브레인, 기업용 ‘맥스AI 전화 영어’ 출시

▷ ‘AI로 기업 어학교육 이수율 잡는다’.. 위버스브레인 맥스AI 전화영어 출시
▷ 위버스브레인 자체 기술 ‘음성 AI 엔진’, 첫 단독 서비스 출시
▷ 설정한 요일·시간에 AI가 능동적 전화…일정 기반 학습 습관 형성 지원

음성 AI 기업 위버스브레인(대표 조세원, 이용국)이 AI 튜터가 학습자에게 먼저 전화를 거는 기업용 '맥스 AI 전화영어'를 22일 출시했다고 밝혔다. 회사가 자체 개발한 음성 AI 엔진을 처음으로 단독 서비스로 런칭한 사례다.

기업 어학교육의 오랜 과제는 낮은 이수율이다. 자율 학습에 의존하는 어학 앱은 학습자가 접속하지 않으면 교육이 이뤄지지 않고, 전화·화상영어는 시간 확보와 비용, 심리적 부담이 꾸준한 학습을 가로막았다. 맥스 AI 전화영어는 학습자의 접속을 기다리지 않고, 사용자가 설정한 요일과 시간에 AI 코치가 앱 내 전화로 10분간 수업을 진행한다. 학습자가 직접 앱을 여는 대신 AI가 능동적으로 사용자에게 전화를 걸어 학습 시작을 유도한다. 기업 임직원은 시간에 구애 받지 않고 업무 일정에 맞춰 선택적으로 학습이 가능하다.

수업 전후 과정도 반복적인 학습을 돕는 방식으로 구성했다. 수업 전에는 예약 알림을 보내며, 첫 전화를 받지 못하면 10분 뒤 한 차례 다시 연결해 참여 기회를 제공한다. 수업 후에는 대화 내용과 학습 내용을 기록한 리포트를 제공해 복습에 활용할 수 있도록 했다.

학습자의 외국어 숙련도와 응답 속도에 따른 맞춤형 학습도 가능하다. 학습자가 한국어와 외국어를 섞어 말하거나 답변을 망설이고 문장을 고쳐 말하는 등 전화 수업 중 발생할 수 있는 다양한 상황에서도 AI 튜터가 대화를 이어가도록 설계됐으며, AI가 말하는 도중에도 학습자는 “다시”, “천천히”, “한국어로 설명해줘” 등의 요청을 할 수 있다. 이러한 기능에는 혼합 언어 인식과 사용자 발화 끼어들기를 지원하는 위버스브레인의 자체 음성 AI 기술이 적용됐다. 회사는 누적 회원 123만 명의 학습 데이터와 6.8억 개의 발화 문장을 기반으로 STT(음성인식), TTS(음성합성) 등 음성 발화 전 구간의 AI 기술을 자체 개발해 왔다.

맥스AI는 현재 300여 개 기업·기관의 임직원 교육에 활용되고 있다. 이번 ‘맥스AI 전화영어’ 서비스 출시로 기업 고객이 선택할 수 있는 AI 외국어 학습 방식을 확대해 경쟁력을 강화했으며, 이를 바탕으로 기업 고객을 확대할 예정이다. 위버스브레인 조세원 대표는 “기업 외국어 교육은 좋은 콘텐츠를 제공하는 것만큼 구성원이 정해진 시간에 학습을 시작하도록 돕는 것이 중요하다”며 “AI가 먼저 찾아가는 수업으로 임직원들의 꾸준한 외국어 학습 습관을 형성하고, 실질적인 학습 효과로 드러날 수 있도록 노력할 것”이라고 밝혔다.
