Generating an M&A Longlist with This AI Tool – How It Works with ProxDeal
In mergers and acquisitions (M&A), creating a so-called longlist is an important first step. ProxDeal solves this challenge by automatically identifying suitable target companies using AI.
In mergers and acquisitions (M&A), creating a so-called "longlist" is an important first step. This list includes potential target companies that might be of interest for an acquisition or potential business buyers. Until now, researching these lists took a long time because it was often done manually. ProxDeal solves this problem by automatically identifying suitable target companies using AI.
The Problem with Manual Longlists
Typically, M&A teams research suitable companies manually. They search industry directories, databases, or networks. This often takes several weeks and consumes a lot of working hours. Additionally, these lists have drawbacks:
- The data quickly becomes outdated
- Important companies are overlooked
- Results depend on personal assessments, which are often based on insufficient data
How ProxDeal Automatically Creates a Longlist
ProxDeal uses a specialized AI technology. This AI searches in real time for companies that exactly match the desired criteria. Instead of relying on pre-existing databases, ProxDeal continuously researches millions of websites.
The software understands complex search queries and then creates a tailored longlist. Users simply enter the types of companies they are looking for. These can include criteria such as industry, location, revenue, or technologies.
Overview of the Benefits:
-
Fast Research: Create a longlist in minutes instead of weeks
-
Artificial Intelligence: The AI finds targets or buyers you would most likely overlook manually
-
Custom Filters: Precise selection based on your M&A criteria
-
Clear Reporting: Exportable lists for further analysis
-
International Data Base: Access to companies beyond Germany
-
Data Enrichment: Automatic enhancement with relevant additional information such as contact details, financial data, etc.
Three Steps to a Completed Longlist
1. Define Criteria
Users enter what the AI should search for. Criteria may include industry, financial metrics, region, size, technology, customer base, or ownership structure.
2. AI Starts Research
The ProxDeal AI analysts automatically search relevant company data and evaluate the results by relevance. The analysis runs in seconds and is sorted by strategic fit. If needed, a deeper analysis of selected candidates can be conducted.
3. Longlist Immediately Available
Users receive a structured longlist instantly. They can export it as an Excel file or in other formats. The results are visually presented, can be filtered, and can be highly personalized for outreach using an integrated outreach tool.
Practical Example: Mid-Sized Company Significantly Improves Hit Rate
A mid-sized machine manufacturer was looking for companies to acquire. Previously, the M&A team needed three months to compile a list of 45 candidates.
With ProxDeal, 137 potential targets were identified within five minutes. Many of these companies had not been found before. The success rate of initial contacts rose from 5% to 38% because the AI also provided contact details of relevant persons.
The team was particularly impressed by the data’s timeliness: While their old database still listed companies that had already been acquired or were insolvent, ProxDeal delivered only current and relevant targets thanks to real-time research.
Integration into the Overall M&A Process
ProxDeal delivers the perfect target companies for the first step of a successful M&A process. This is followed by outreach, company due diligence, and ultimately contract negotiations.
This is exactly where Viaductus comes in. The platform guides users through all phases of the M&A process.
