Turn Idea Overload into Real Results with the Innovation Funnel

In business management, the idea of a funnel is often used as a metaphor to better structure processes. That’s exactly the case with the innovation funnel, a way to realistically manage the entire innovation journey.

Not all ideas generated within a company have the same potential. Trying to execute them all may lead to wasted resources and lost opportunities.

To optimize efforts and reach the expected results, companies use the innovation funnel. It helps keep innovation alive by guiding initiatives, aligning them with corporate strategy, and ensuring resources are directed toward projects with real impact.

In this article, you’ll learn how the innovation funnel works in practice, its 3 main stages, and how it can be applied to both internal idea programs and open innovation.

What Is an Innovation Funnel?

The innovation funnel is a management tool used to analyze and select the innovative ideas generated within a company, filtering those that are feasible and worth executing.

This way, resources can be directed more strategically, avoiding time, money, and talent being wasted on proposals that look good on paper but aren’t practical or impactful when executed.

In short, the funnel ensures that only the strongest, most promising ideas are developed into innovation projects that create real business value.

The 3 Stages of the Innovation Funnel

The funnel is divided into three large stages — top, middle, and bottom — each with its own function:

1. Top of the funnel → Idea generation and collection
2. Middle of the funnel → Screening, prioritization, and evaluation
3. Bottom of the funnel → Execution and implementation of selected ideas

Let’s explore each in detail.

Metrics in Innovation Programs

Whether applied in closed innovation (intrapreneurship and internal idea programs) or open innovation (partnerships with startups, universities, and other players), programs must have well-defined processes and clear metrics to monitor progress.

Key metrics across the innovation funnel include:

• Volume: Measures the total number of ideas submitted or startups engaged in an open challenge.
• Conversion: Percentage of ideas that move from submission to implementation, or ideas submitted per employee.
• Time: Tracks average duration for each step — from idea submission to project launch, campaign cycle time, or time until a project generates impact.

Top of the Innovation Funnel

The top stage focuses on capturing as many ideas as possible. This requires extensive mapping of company challenges and opportunities, often involving both employees and external partners in the case of open innovation.

At this stage, leaders must engage and train employees to actively contribute ideas. After all, employees are often the company’s greatest source of insights and problem-solving.

Strategies include internal communication campaigns, dedicated workshops, and interactive platforms such as AEVO Innovate, which structures and manages corporate idea programs.

Example of top-funnel indicators:

• % of employees engaged with the program
• Number of ideas submitted per department
• Average ideas submitted per employee

The following video explains well how putting people and their ideas at the center matters:

Middle of the Innovation Funnel

The middle stage is where the initial filtering and prioritization take place. Ideas collected are analyzed for risk, feasibility, and alignment with company strategy.

This stage requires clear evaluation criteria and defined ownership. Sometimes, for simple ideas, frontline workers themselves can make the approval — such as changing a machine part to reduce breakdowns. This decentralization speeds up decision-making and empowers employees.

For more complex ideas, approval may involve an innovation committee or R&D department, since they demand greater investment and carry more risk.

Middle-funnel indicators include:

• Number of ideas selected for further development
• % of ideas approved vs. submitted
• Approved ideas per campaign

Bottom of the Innovation Funnel

At the bottom, selected ideas are turned into concrete innovation projects. This stage is the most complex, requiring development, implementation, and complementary activities such as:

• Securing funding for the project
• Training employees for adoption
• Designing a marketing strategy to launch the innovation

At this stage, evaluating the ROI of innovation is critical. ROI can be measured financially or by the time and resources invested.

Case Example: Energisa, a Brazilian energy group, achieved ROI 12 times higher than expected in 2021 and 20 times higher in 2022 by implementing initiatives structured within their innovation funnel.

Using the Funnel in an Idea Management Program

Here’s how the funnel applies to a corporate Idea Program:

• Top of the funnel: Idea generation and collection through the innovation management platform.
• Middle of the funnel: Filtering and selecting viable ideas, decentralized for simple ones or evaluated by committees for complex ones.
• Bottom of the funnel: Execution of projects, ROI analysis, and learnings for future initiatives.

The Innovation Funnel in Open Innovation

The funnel can also be adapted to open innovation, where companies collaborate with external partners such as startups, universities, and research institutes.

In this context, the funnel stages are:

1. Top: Launching an innovation challenge and connecting with external partners. Indicator: number of companies/startups registered.
2. Middle: Screening participants for alignment with the challenge. Indicator: % of aligned companies vs. registered.
3. Bottom: Pitch evaluation, partner selection, and pilot development.

Through partnerships, companies expand their innovation capacity and create fertile ground for diverse solutions, while still filtering ideas strategically through the funnel.

AEVO Innovate offers dedicated modules for open innovation, enabling companies to manage the entire funnel, from challenge launch to pilot execution, while connecting with startups through its Connect community.

Conclusion

The innovation funnel ensures continuity and effectiveness in innovation initiatives. By filtering and prioritizing ideas, companies direct resources toward those with the greatest potential for impact and ROI.

Whether applied internally through idea programs or externally through open innovation, the funnel structures the path from raw idea to implemented solution, making innovation a sustainable part of corporate strategy.
