The honest comparison
Two different problems, often confused
Buyers searching for "Celonis alternatives" usually want one of two things: process optimization or organizational discovery. They are not the same category. Use this table to find which side of the line you are on.
| Dimension | Celonis | Horizon |
|---|---|---|
| What it reads | System logs (ERP, CRM, ticketing, automation) | Employee conversations at scale |
| What it surfaces | How processes run inside your systems | What your people know, think, and flag |
| Discovery speed | Weeks to months of integration | Full-org diagnosis in about 5 days |
| Who it listens to | Systems and structured data | Every employee, not just leaders |
| Best for | Process optimization at scale | Organizational discovery and alignment |
| Typical buyer | VP of Operations, Chief Process Officer | VP / Director of Transformation |
| Integration required | Heavy (ERP, CRM connectors) | Minimal, conversation-based |
| Price range | $100K to $500K+ per year | Contact for pricing |

No winners declared. The right tool depends on which question you are trying to answer.
The blind spot
What process mining doesn't capture
Celonis builds a digital twin of your operations. It shows what happens inside your systems: every step, every handoff, every variant.
It does not capture what employees believe is broken, what they are working around, or why two departments interpret the same strategy differently. None of that lives in an event log.
The best-run organizations need both layers: the digital layer Celonis reads, and the human layer Horizon hears.
Process mining
What Celonis sees
- System event logs and process flows
- ERP and CRM transaction data
- Automation events and bottlenecks
- Variants between expected and actual paths
Organizational discovery
What Horizon hears
- Employee conversations across the org
- Hidden inefficiencies and workarounds
- Strategic misalignment between teams
- What people see but rarely say out loud
Trusted at scale
Trusted by organizations that needed both layers
Horizon has run more than 10,000 employee conversations across enterprise clients in finance, retail, logistics, and pharma.
Some of our clients came to Horizon after implementing process mining tools, and found they still could not answer the question that mattered most: what do our people actually see?
Self-select
Which one is right for you
Three short reads. Pick the one that sounds like you.
Choose Celonis if:
Your problem is process, not people.
- You need to optimize specific system-driven processes (procure-to-pay, order-to-cash, claims).
- You already have rich event logs in ERP, CRM, or workflow tools.
- You can fund a multi-month integration and change-management effort.
- You measure success in cycle time, throughput, and automation rate.
Choose Horizon if:
Your problem is what people see, not what systems log.
- You need a full-org diagnosis in days, not months.
- You want to hear from every employee, not a sample of leaders.
- Your inefficiencies live in handoffs, decisions, and unwritten rules.
- You need prioritized initiatives with owners, not another dashboard.
Use both if:
You run a large enterprise with both kinds of debt.
- Celonis tells you where systems break down.
- Horizon tells you where the organization breaks down.
- Together they cover the digital and the human layer of how work happens.
- Some Horizon clients arrived after process mining and asked the next question: what do our people actually see?

FAQ
Common questions about Celonis alternatives
What are the best alternatives to Celonis?
It depends on the problem you are solving. For process optimization based on system logs, alternatives include Celonis, Apromore, UiPath Process Mining, and IBM Process Mining. For organizational discovery based on employee conversations, Horizon is the category leader. The two approaches solve different problems: process mining captures what systems do, organizational discovery captures what people know.
How is Horizon different from Celonis?
Celonis is a process mining platform. It reads system logs from your ERP, CRM, and other tools to map how processes actually run. Horizon is an organizational discovery platform. It interviews every employee through conversational AI to surface what people know, think, and flag. Celonis answers 'how does this process run in our systems'. Horizon answers 'what is broken across our organization that nobody is logging'.
Is Horizon a process mining tool?
No. Horizon is not a process mining tool. Process mining requires structured event logs from systems like SAP, Oracle, or Salesforce. Horizon works through conversations with employees and surfaces insights that never reach a system log: tribal knowledge, workarounds, misalignment, and ideas. Many organizations use both, because process mining and organizational discovery are different layers of the same problem.
Can Horizon replace Celonis?
Not for process mining use cases. If your goal is to optimize a specific process by analyzing system events, you need a process mining tool. Horizon replaces traditional consulting and employee surveys, not process mining. Several Horizon clients run both, because the two tools answer different questions.
How long does Horizon take to deploy compared to Celonis?
Horizon delivers a full organizational diagnosis in about 5 days. There are no ERP or CRM connectors to build. Celonis deployments typically take weeks to months because they require event-log extraction, data modeling, and ongoing integration with source systems.
Which is right for a transformation leader evaluating both?
Start with the question you are trying to answer. If you need to know how a system-heavy process runs, start with Celonis. If you need to know what every employee sees, where strategy is misaligned, and where to focus first, start with Horizon. Many enterprise leaders run both in parallel: Celonis for the digital layer, Horizon for the human layer.
Not sure which one fits your problem?
We will tell you honestly whether Horizon is the right answer, even if the answer is process mining. 30 minutes, no pitch deck.
