Five years together.All the way to acquisition.

From a language AI platform, through chat agents, to voice AI — and an acquisition by monday.com.

OneAI is a conversational AI platform that developed advanced language intelligence, AI agents and autonomous voice technology for businesses. For five years we worked alongside the team as a long-term technology partner — from developer APIs, through intelligent chat agents, to a voice AI system managing real-time business conversations.

The journey reached a major milestone in 2026, when OneAI was acquired by monday.com to add voice agent capabilities to its expanding AI platform.

01 / About OneAI

Making advanced AIsomething businesses can run.

OneAI was created to make advanced artificial intelligence and natural language capabilities accessible to businesses and developers. Initially the platform provided language AI through APIs — analyzing content, identifying meaningful information and turning natural language into structured data. As generative AI evolved, the product expanded into chat agents and later a complete voice AI platform.

02 / A long-term partnership

Not a project.A partnership.

For five years we operated as an ongoing technology partner inside a fast-moving startup, where the product, market and technology continuously evolved. Rather than acting as an external vendor around an isolated task, we became an integral part of the product-building process. That required us to:

  • Develop a deep understanding of the product and business vision.
  • Work closely with leadership, product and engineering teams.
  • Adapt the platform to rapid changes in the AI industry.
  • Design capabilities that could scale over time.
  • Support multiple versions and product directions.
  • Continuously improve the user experience.
  • Connect complex AI infrastructure with intuitive interfaces.
  • Maintain the pace a growing startup demands.

03 / The challenge

Ten technology layers.One simple product.

The central challenge was turning highly complex AI technology into a product businesses could configure, operate and manage simply. The platform had to connect:

  • NLP and AI models
  • Business content and knowledge
  • Conversation design
  • AI agents
  • Telephony infrastructure
  • Real-time voice interactions
  • CRM and calendar systems
  • Transcripts and recordings
  • Analytics and optimization
  • Developer APIs

All of it in one of the fastest-changing areas of technology — without sacrificing stability or overwhelming users.

04 / The solution

From AI capability —to a clear business workflow.

Throughout the partnership we supported a product experience that transforms advanced AI capabilities into business workflows. The platform was structured around a repeatable process:

  1. Define the agent's business objective
  2. Connect relevant knowledge and business systems
  3. Design the conversation flow
  4. Configure how the agent responds and acts
  5. Deploy the process with real customers
  6. Collect conversation data and outcomes
  7. Analyze performance
  8. Continuously improve

Business teams operate sophisticated AI systems — without managing the infrastructure behind them.

05 / From language AI to agents

First understand language.Then take action.

OneAI's earlier products focused on turning natural language into structured, useful information — through APIs. That infrastructure became the foundation for agents that don't just analyze information, but interact and act:

  • Content summarization
  • Topic & keyword detection
  • Information extraction
  • Content classification
  • Language analysis
  • Document processing
  • Unstructured language → structured data
  • Embedding AI in existing products

06 / The evolution to conversational AI

From AI behind the scenes —to an agent talking to customers.

Instead of operating only behind the scenes, businesses could create an agent that communicates directly with users, understands their requests and responds using the organization's content and systems. The design challenge: meaningful control without a complicated technical tool.

  • Natural conversations
  • Context preservation
  • Access to current business information
  • Configurable goals and rules
  • Controlled responses
  • Reduced hallucination risk
  • Multilingual experiences
  • Data transfer to external systems

07 / The voice AI platform

Agents that pick up the phone.And make the call.

OneAI later evolved into a complete AI voice agent platform: inbound and outbound calls, lead qualification, appointment scheduling, follow-ups and human transfers — plus campaign management, call timing, transcripts and recordings.

  • Inbound and outbound phone calls
  • Rapid follow-up with new leads
  • Lead verification and qualification
  • Real-time appointment scheduling
  • Meeting confirmation and reminders
  • Automated follow-up calls
  • Phone, SMS and chat communication
  • Warm transfers to human reps
  • Voicemail and IVR handling
  • Continuous operation after hours

08 / Conversation flow design

AI intelligence.Business rules.

Rather than relying on a completely unrestricted model, businesses build structured flows that control messaging, process and customer experience. A flow can define:

  • How the call begins
  • Which questions the agent asks
  • What information to collect
  • How to respond to different answers
  • When to schedule a meeting
  • When to transfer the call
  • What happens with no answer
  • How objections are handled
  • What counts as success

09 / Intelligent human handoffs

The rep joins the call.Already knowing everything.

When the AI identifies a qualified lead or a situation requiring human attention, it transfers the live conversation to the relevant rep — with a briefing of the call so far. The rep joins already knowing:

  • Who the customer is
  • What they're looking for
  • Which questions were asked
  • How the customer responded
  • Whether they meet the qualification criteria
  • What should happen next

The result: a smooth transition between automated conversations and human teams.

10 / Analytics and optimization

Every call measured.Every version tested.

A successful voice interaction is measured by more than whether a call took place. The platform collects data that drives continuous improvement — including A/B and multivariate testing across scripts, sequences and voices:

  • Contact and answer rates
  • Lead qualification rates
  • Human handoff rates
  • Conversation outcomes
  • Transcripts and recordings
  • Script comparisons
  • Voice and accent testing
  • Call-time optimization
  • Audience and segment analysis
  • Conversion attribution
  • Operational reporting

11 / Integrations and API

Part of the business stack.Not an isolated app.

Agents read relevant information before a conversation and update connected systems in real time with the outcomes. The platform connects to CRMs, calendars, telephony, messaging, advertising and lead management — and provides API access for embedding its capabilities into custom products.

  • CRM platforms
  • Scheduling systems
  • Calendars
  • Telephony providers
  • Messaging tools
  • Advertising platforms
  • Lead management
  • Internal services

12 / UX for a complex AI product

Two audiences.One product.

The most important challenge was translating deep technical capability into an experience users could understand and operate — accessible to non-technical teams without limiting the depth advanced customers need.

  • 01
    Business users
    Launch campaigns, configure agents, monitor calls and improve results — without writing code.
  • 02
    Developers and technical teams
    Integrate APIs, configure advanced workflows and connect deeply with external systems.

13 / Management and operations

From an AI engine —to a daily operating platform.

Alongside the AI engines, the platform includes interfaces that turn the technology into a daily tool for sales, support and operations teams:

  • Creating agents
  • Managing conversation flows
  • Uploading contacts and leads
  • Launching campaigns
  • Defining calling schedules
  • Monitoring conversations
  • Reviewing outcomes
  • Reading transcripts
  • Listening to recordings
  • Managing integrations
  • Tracking performance
  • Improving scripts and workflows

14 / A rapidly changing industry

AI changed end to end.The product stayed stable.

During our five-year partnership, the AI landscape moved from NLP models, through generative AI, to autonomous agents managing real-time voice conversations. The long-term partnership enabled us to:

  • Maintain continuity and deep product knowledge.
  • Adapt the platform to new technologies.
  • Improve existing systems without rebuilding everything.
  • Rapidly develop new product directions.
  • Preserve consistency across the user experience.
  • Support the company throughout growth and transformation.
