Cooperating with Competitors: When It Makes Sense and Is Allowed

Two businesses that normally compete for the same orders submit a joint bid for a large project. That can be smart and is often permitted. But it can also cost know-how or violate competition law. This article shows where the lines run.

Key takeaways

  • Coopetition describes relationships in which companies cooperate and compete at the same time. For small businesses, it is often the only way to large contracts or expensive development work.
  • The separation principle according to Bengtsson and Kock (2000) recommends separating cooperation and competition by task: develop or deliver jointly, sell and set prices separately.
  • Price fixing, allocating customers and territories, and coordinated bids are prohibited. Bidding consortia are permitted if the businesses could not perform alone or if it is a reasonable business decision.
  • Small businesses are especially vulnerable in cooperation with larger firms. Contracts, clear responsibilities, and ongoing coordination provide the most effective protection (Gernsheimer, Gast, and Kanbach 2024).

Why working with competitors is an obvious idea

A public authority tenders the maintenance of all school buildings in a district. A small business could handle half, but not all of it. A competitor from the neighboring town has the same problem. Together they would meet the requirements. Similar situations arise in purchasing, when two businesses together would get better terms, or with an expensive testing facility that neither can afford alone.

That raises one question: When is working with a competitor sensible for a small business, when is it permitted, and how does the business protect its know-how in the process? To answer it, we first clarify the terms, introduce the separation principle as a mental model, outline the legal framework, review what research shows, and finally arrive at a check to run before every cooperation.

You may do many things together with a competitor. You just do not talk about prices, customers, or bids.

Terms: coopetition, horizontal agreement, bidding consortium

  • Coopetition: A relationship in which companies cooperate and compete with each other at the same time. The term combines the words cooperation and competition.
  • Horizontal agreement: An agreement between companies at the same level of the market, that is, between actual or potential competitors. It is subject to stricter competition law scrutiny than an agreement between supplier and customer.
  • Bidding consortium: A combination of several companies that submit a joint bid for a specific contract and carry it out together.
  • SME cartel (Mittelstandskartell): A cooperation among small and midsize companies that, under § 3 GWB, the German Act against Restraints of Competition, is exempt from the cartel prohibition under certain conditions.

Working with a competitor is a special case of partnership. How partnerships in general are selected, agreed, and managed is described in the guide Setting up sales partnerships. Where it stands compared with own growth and acquisition is explained in the comparison Organic, partnership, or acquisition.

The mental model: coopetition and the separation principle

Maria Bengtsson and Sören Kock (2000) described how companies deal with the tension of being partners and opponents at the same time. Their best-known proposal is the separation principle: cooperation and competition are separated by task. Typically, companies cooperate in upstream activities such as development, purchasing, or production and continue to compete in downstream activities such as sales and marketing. Later research added two further principles: integration, the ability of individuals to keep both roles in mind, and co-management by a dedicated team separated from the rest of the organization.

Where competitors cooperate and where they stay separate, according to the separation principle
AreaPossible jointlyKeep separateCompetition law sensitivity
PurchasingPooled orders from suppliersOwn selling prices and customer listsLow to medium, depending on market share
Development and testingShared testing facility, joint developmentMarketing of the resultsLow, with its own exemption rules
Performing large contractsBidding consortium for a specific contractAll other bidsMedium, justification required
SalesHardly anythingPrices, discounts, customers, territoriesHigh

The separation principle is useful for small businesses for two reasons. It protects know-how, because the partner only sees what is needed for the joint task. And it largely coincides with what competition law requires: the closer a cooperation comes to price and customer, the more sensitive it becomes.

What research shows about coopetition among small businesses

Gernsheimer, Gast, and Kanbach (2024) studied 25 innovation projects, each involving a small or midsize company working with a large competitor. The projects come from agrochemicals, where small specialists develop biological crop protection products and large manufacturers can market them. The authors describe the starting situation clearly: large partners can copy technologies, extract know-how, and use the smaller firm’s capabilities for themselves. Small businesses have less power, and their size and youth make it harder for them to recover from such a loss.

Successful small companies switched between three forms: co-distribution, technology licensing, and joint development. Depending on the form, they combined separation, integration, and co-management, and in the closest form also co-ownership of the results. The authors further emphasize that formal means such as contracts, procedures, and good governance limit opportunistic behavior, and do so most effectively together with informal means such as shared goals, open communication, and continuous dialogue.

In their overview, the authors refer to a study by Lechner and colleagues (2016) of 82 start-ups in Germany, according to which cooperation with larger companies at other levels of the market promoted the small firms’ sales growth. The findings come from innovation projects. For a bidding consortium of two trade businesses, they are an indication of the risks, not a recipe.

Two views: strength through pooling or danger to your own business

The first view emphasizes the opportunities. Small businesses can win contracts together, share costs, and use facilities neither could finance alone. The legislator explicitly recognizes this: the SME cartel under § 3 GWB is intended precisely to improve the competitiveness of small and midsize companies.

The second view emphasizes the dangers. Working with a competitor gives them insight into processes, costing, and customers. What starts in a bidding consortium can be used against your own business in the next competition. Then there is the legal risk: conversations about a joint contract can easily turn into conversations about prices and customers, which are prohibited.

Opportunities and dangers of working with competitors

Opportunities

  • Access to contracts neither could fulfill alone
  • Shared costs for purchasing, testing, and development
  • Explicitly intended support for small and midsize firms
  • New capabilities through the partner

Dangers

  • Leakage of costing, customer knowledge, and technology
  • Dependence on the stronger partner
  • Prohibited agreements in side conversations
  • Fines and, in tenders, criminal liability

I consider both views justified and see the balance in the separation principle. A cooperation limited to a specific task, based on a written agreement, and explicitly excluding prices, customers, and territories uses the opportunities and limits both risks. How businesses protect their know-how, including from partners, is described in the article Industrial espionage in small and midsize firms.

The check before every cooperation with a competitor

The mental model, legal framework, and findings yield a five-step check. It does not replace legal advice, but it ensures the right questions are asked before the first joint meeting takes place.

  1. Purpose in one sentence

    What exactly is to be done jointly, and why is it not possible alone? For a bidding consortium, the capacity calculation belongs here.

  2. Separate tasks

    Define which areas are joint and which remain separate. Prices, discounts, customers, and territories never belong in the joint part.

  3. Limit information

    Determine which data are exchanged and who sees them. Current prices, capacities outside the contract, and customer lists stay out.

  4. Agree in writing

    Purpose, duration, division of tasks, liability, handling of know-how and results, and the end of the cooperation belong in a contract that is reviewed before work begins.

  5. Document meetings

    Keep a short agenda and minutes for joint meetings. If the conversation turns to prices or customers outside the contract, end it.

Conclusion: when cooperation makes sense and is allowed

When is working with a competitor sensible and permitted for a small business? It is sensible when it opens access that neither would have alone: a large contract, pooled purchasing, or expensive development. It is permitted as long as it does not touch prices, customers, territories, and bids. Bidding consortia are permitted if the partners could not perform alone or the joint bid rests on a reasonable business decision, and cooperation among small businesses can be exempt as an SME cartel. The separation principle according to Bengtsson and Kock combines both requirements: together where necessary, separate where competition and know-how must be protected. Research shows that small businesses in particular need contracts and ongoing coordination so as not to become the weaker side.

  1. This week: Note which contracts or purchases you could not bid for alone in the last two years.
  2. Next week: For the most promising case, write the purpose in one sentence and separate joint and separate tasks.
  3. Before the first meeting: Have the purpose and the draft contract reviewed by a competition law specialist.

You can recognize a good cooperation with a competitor by the fact that after the contract both compete just as hard for the next customer as before.

Frequently asked questions

Am I allowed to cooperate with a competitor?

In principle yes, for example in purchasing, development, or jointly carrying out a contract. Agreements on prices, discounts, customers, territories, and bids are prohibited. Whether a specific cooperation is permitted should be reviewed by a specialist; this article is not legal advice.

When is a bidding consortium permitted?

According to case law, in particular when the partners could not carry out the contract alone, for example because capacities are tied up, or when only the consortium makes a promising bid possible based on a reasonable business decision. Contracting authorities often require a justification.

What is an SME cartel?

A cooperation among small and midsize companies that is exempt from the cartel prohibition under § 3 of the German Act against Restraints of Competition if it rationalizes economic processes through cooperation, does not substantially impair competition, and improves the competitiveness of small and midsize companies.

What is coopetition?

A relationship in which companies cooperate and compete at the same time. A proven way of handling it is the separation principle: together in upstream areas such as development or purchasing, separate in sales and on prices.

How do I protect my know-how in a cooperation?

Through a limited purpose, a clear separation of tasks, a contract with rules on know-how and results, a single contact person, and not exchanging prices, capacities, or customer lists.
