PITCH: Prototype your concept

    You prototype your technology. Why not prototype your concept?

    A prototype isn't the finished answer. It's a way to ask a question, test an assumption, and learn before you've over-invested.

    Follow the guided journey to learn the approach, or jump directly to the tools you need. Start anywhere and return as your concept evolves. Looking for step-by-step instructions? View the Quick Start Guides.

    WHY

    Why prototype a concept?

    A concept prototype is a lightweight way to test an idea before committing substantial time and resources. It exposes assumptions, brings different perspectives into the development process, and helps you refine what matters most. In PITCH, your pitch becomes that prototype—a structured, testable representation of your concept that evolves through feedback, discovery, and evidence.

    Meet Essie

    Essie — The Early-Stage Investigator

    “My science is strong. I'm confident proposal reviewers will eventually see what I see.”

    Meet Essie. She's a talented early-stage investigator with a compelling research idea. She's confident in her science, understands the importance of the problem, and believes her approach is innovative. She's written scientific papers before. How different could a research proposal be?

    The problem

    Essie has submitted proposals she believed were competitive, only to receive disappointing reviews. She addresses the reviewers' criticisms, but the next submission seems to reveal entirely new weaknesses. The process feels like a black box.

    She's confident in her science and the importance of her research. But she's so close to her own idea that she struggles to see it through someone else's eyes. Reviewers must be persuaded not only that her work is technically sound, but that it's distinctive, compelling, and worth funding now—especially when competing proposals also address important problems.

    The PITCH promise

    PITCH helps Essie step outside her own perspective and examine her research concept through the eyes of proposal reviewers—and begin to recognize how proposal writing differs from writing scientific papers.

    Through guided concept prototyping, she can test assumptions, identify overlooked weaknesses, and reframe her research as a compelling case for investment. Why is the problem important? What makes her approach different? Why should this work be funded now, ahead of other worthy proposals?

    Rather than simply improving her scientific writing, Essie can develop a coherent, persuasive story that reviewers understand, remember, and are willing to advocate for.

    Why PITCH?

    What if you could read a reviewer's mind? You can't, of course, but you can learn to see your research through their eyes.

    You can ask a general-purpose AI to critique your proposal. But how do you know which questions to ask, whether its assessment is consistent, or what evidence it actually found? PITCH provides a guided development process and a defined evaluation framework, helping you examine your concept from both your own perspective and that of a potential reviewer. Its evidence-grounded assessments show what supports the evaluation—and where your intended argument may not be coming through.

    Work independently, revise at your own pace, and return to your developing concept and assessments as you improve your case. Bring a stronger proposal—and better questions—to your mentor, so your conversations can focus on the deeper issues where human experience and judgment matter most.

    DEMOS

    Explore PITCH through these example Challenges. Each has been preconfigured with a Problem and evaluation framework using the principles introduced in DESIGN. These examples illustrate different applications of PITCH and can be customized to suit your needs.

    Get Started

    Objective

    Independently develop your first focused concept prototype, see how it aligns with an existing opportunity, and use preliminary quality feedback to identify opportunities for improvement through the eyes of potential reviewers.

    What to Do

    Core Pathway

    DESIGN: Review Quick Start to explore existing Problems and Challenges in our library. As needed, learn how to upload your own solicitation to customize your Problem.

    DISTILL: Review the introductory explanation of concept prototyping and Test Your Prototype to understand how PITCH helps researchers develop, evaluate, and refine emerging concepts. Pay particular attention to how evaluation feedback reflects the expectations of different reviewers and funding opportunities.

    Example Use Cases

    Select a Challenge from one of our Demos to experience different approaches to developing and evaluating a concept prototype. These demos are pre-configured use cases with a problem and evaluation predefined. Note: The NSF CAREER Challenge uses Adaptive Coaching; you will be prompted to provide details and piroirties from your specific program. Please refer to the program description to find these details, as they will be used in the interactive chat to help you define and specifically address these targets. Although optional, investigating and distilling your technical context helps you understand how your proposed research relates to the broader field, while allowing Adaptive Coaching to ask more relevant questions about your concept.

    Alternatively, go to Pitch and choose a problem, evaluator, and scoresheet of your choice. Review the alignment and evaluation scores and iterate.

    Additional Resources

    DESIGN: Review Or Design Your Own Challenge Environment to learn how to configure your own Problem and evaluation environment.

    Evaluation Framework: Understand how PITCH evaluations are conducted, how scores are derived, and how to interpret the resulting feedback.

    DEEPEN: Explore advanced tools for optimizing your final outcome, including risk and contingency planning and development of a risk–reward matrix.

    Develop & Refine

    Objective

    Refine your concept through iterative evaluation, using different Quality Rubrics and Reviewer Personas to distinguish weaknesses in the concept itself from differences in evaluator expectations.

    What to Do

    DISTILL: Return to your concept prototype on Pitch and revise it in response to your initial evaluation. Focus on strengthening the problem significance, differentiation, and case for investment rather than simply improving the writing.

    Reevaluate after each meaningful revision. What improved? Which concerns remain? Are new questions emerging?

    DISTILL: Experiment with different Quality Rubrics and Reviewer Personas using the dropdown menus on Pitch. Compare how different evaluation criteria and reviewer perspectives influence the feedback.

    Identify weaknesses that persist across evaluations versus concerns that arise from a particular reviewer's expectations. Use these distinctions to prioritize your next revisions.

    DESIGN: If the existing evaluation options do not adequately represent your funding opportunity, create or customize a Quality Rubric or Reviewer Persona.

    For example, you might model the expectations of a particular funding program, a knowledgeable mentor, or a skeptical reviewer. You can also upload a relevant technical paper to customize a Reviewer Persona with expertise in your research area. This provides a more technically informed first-pass critique, beyond the general proposal-development feedback your research office or mentors may already provide.

    Return to Pitch to evaluate your revised concept from that perspective.

    Test & Optimize

    Objective

    Challenge your concept's underlying assumptions by testing alternative Problem framings, examining how different definitions of the problem, customer needs, and intended outcomes influence its significance and positioning.

    What to Do

    DESIGN: Create or adapt a Problem that reflects the research need, intended beneficiaries, pain points, and outcomes your concept is meant to address.

    Experiment with alternative Problem framings. For example, with Adaptive Coaching on, consider a different outcome, pain point, or evaluation focus.

    DISTILL: Return to your concept prototype on Pitch and evaluate it against your alternative Problem framing.

    Examine whether the revised framing changes the perceived significance, alignment, or value of your approach. Does it expose an assumption you had overlooked? Does it reveal a stronger argument for why your research matters?

    Use these insights to refine your concept's positioning and strengthen its case for investment.

    Additional Capabilities

    DEEPEN: Apply advanced development tools to your refined concept. Develop a risk–reward matrix to examine potential scientific or technical gains against the risks involved, and use risk and contingency planning to strengthen your proposed approach.

    Consider how these elements could help you anticipate reviewer concerns, in particular, contingency plans, risk, and execution. Consider these ideas to present a more convincing case for feasibility and impact.

    Use as much—or as little—structure as the question requires. Return and go deeper as you learn.
