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

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.

"실제 원어민과 대화하듯…AI튜터로 영어회화 공부" 조세원 스터디맥스 대표



"챗GPT를 활용한 영어회화 서비스에 실제 원어민의 악센트를 더해 기계가 아닌 사람과 대화하는 듯한 느낌을 현실감 있게 구현했습니다."

조세원 스터디맥스 대표는 최근 매일경제와 만나 챗GPT를 활용해 원어민 강사 없이 영어회화가 가능한 AI 튜터와 AI동시통역학습기를 연내 출시할 예정이라고 밝혔다.

조 대표는 "미국의 영어교육 업체 스픽이 음성으로 대화를 주고받을 수 있는 챗GPT 기반 회화 서비스를 선보였지만 억양 등이 아직 자연스럽지 못해 이런 부분을 개선할 수 있다고 생각했다"며 "스터디맥스에는 스피킹맥스 서비스 구현을 위해 5년에 걸쳐 2322명의 원어민에게서 수집한 음성 자료가 있는 만큼 다양한 악센트를 반영할 수 있었다"고 설명했다.

스터디맥스 직원들은 2012년 출시한 영어회화 학습 서비스 '스피킹맥스'의 자료 수집차 2011년부터 2016년까지 5년간 매달 영어권 국가를 방문했다. 미국 뉴욕의 변호사부터 LA에서 생활하는 배우, 하와이의 관광업 종사자 등 다양한 직종의 원어민을 만나 상황에 맞는 대화를 나누는 생생한 영상 자료를 담아 왔다. 이 같은 생생한 음성 자료와 음성인식 기술인 스피치 투 텍스트(STT), 텍스트 투 스피치(TTS) 기술을 접합시켜 AI와 실제 대화하듯이 영어 회화를 연습할 수 있는 서비스를 구현했다.

자연스럽고 다양한 억양 구현
시간∙물리적 제약 뛰어넘어
외국어 교육 크게 변화할 것



조 대표는 2000년 서울대 벤처동아리 시절 온라인 교육 플랫폼 기업 '이투스'를 창업한 멤버 중 한 명이다. 2010년 교육 앱 개발사 '워터베어소프트'를 창업했으며, 이후 미국 입시학원인 '프린스턴리뷰' 최고제품책임자(CPO)와 AI 기반 에듀테크 기업 '뤼이드' 부대표를 거쳐 올해 스터디맥스 대표로 취임했다.

조 대표는 스터디맥스 합류 배경에 대해 "인터넷의 등장으로 네이버 등 포털과 온라인강의 업체들이 성장하고, 모바일 확산으로 카카오와 배달의 민족이 성장하는 것을 지켜봤다"며 "챗GPT라는 '언어천재'가 등장하면서 외국어 교육이 가장 빠르게 그 잠재력을 실현할 수 있는 분야라고 생각했다"고 밝혔다.

조 대표는 "AI 튜터를 통해 원어민 선생님에게 배우는 데 드는 높은 비용과 시간적·물리적 제약을 뛰어넘을 수 있게 된다면 외국어 교육이 크게 바뀔 것"이라며 "이 같은 AI 튜터를 탑재한 AI동시통역학습기 출시도 준비 중"이라고 밝혔다.

그는 이어 "AI동시통역학습기는 개인 외국인 비서처럼 계속 외국어로 대화할 수 있고 실제 외국인과 대화할 때 동시 통역과 더불어 녹음 및 분석 기능을 제공할 뿐 아니라 해당 단어나 표현을 저장해서 추후 학습할 수 있도록 한다"며 "스마트폰과 유사한 외형의 별도 디바이스로 노이즈캔슬링을 통해 보다 매끄럽게 통역이 가능한 것이 특징"이라고 설명했다.

한편 스터디맥스는 추후 한국어 회화 서비스 구현 및 글로벌 진출도 모색 중이며 사업 확장을 위해 네이버와도 협업을 진행하고 있다.

조 대표는 "첫 회사가 이투스이다 보니 뜻하지 않게 교육업계에 몸담게 됐다"며 "저희는 나름대로 기존에는 고액으로만 가능했던 강의를 저렴하게 제공했다는 보람이 있었지만 교육업계의 비즈니스가 사회적으로 인정받지 못하는 것이 다소 아쉬움으로 남았다"고 밝혔다.

그는 이어 "특히 엔터나 게임에 비해 교육업계는 아직 전 세계적으로 인정받는 분야가 아니다"며 "챗GPT라는 큰 흐름을 타고 기여할 수 있는 부분을 찾아 한국 교육회사들이 외국어 교육, 나아가 전체 교육을 리드할 수 있다는 것을 보여주고 싶다"고 포부를 밝혔다.
