Getting feedback is essential since it provides an external perspective that highlights our strengths and reveals blind spots. Information on how others perceive us enables us to refine our behaviors and self-awareness effectively.

Yet, giving and receiving feedback remains a challenge. Lumy aims to change that. From a gentle reminder to actually helping you figure out how to put it, Lumy will be there to guide you. The only thing now standing in the way is your own discomfort.

Giving and receiving peer feedback is essential to foster growth, build stronger teams, and help individuals improve their skills in ways that managers alone might not see. Peer feedback offers valuable perspectives from colleagues who work side by side on day-to-day tasks, often making it more relevant and actionable.
At the same time, it can be challenging: people may hesitate to be fully honest for fear of straining relationships, or they may struggle to phrase constructive feedback in a way that doesn’t feel personal or critical.

Lumy perfectly captures the value of the light-weight, just-in-time peer feedback, while overcoming many of the challenges which existing solutions are riddled with.

I've tried building a feedback culture in the past and know how difficult it can be to make it stick. Lumy is really a game-changer in creating feedback habits that stick within the platform we are already using (Slack).

It's simple, seamless, and a true enabler to building strong teams with healthy feedback habits.

How do I work?

(I’ll show you!)

Step 1: Click a button — easy!

Feedback time! Just tap a button and I’ll walk you through it.
No commands, no confusion.

No need to remember commands or chase people.
I make it easy to start the conversation with just one click.

Step 2: I guide the flow

Once you type your thoughts, I use AI to turn them into clear, kind, and constructive feedback that actually helps the other person grow.

.. and support every step of the way

I make sure your feedback fits your team’s style and structure. Whether you’re following a framework or just winging it, I’ve got your back.

Step 3: Feedback delivered — with care

Ta-da! Feedback delivered — privately and with good vibes.

Your teammate gets a well-written, respectful message that’s easy to read — and backed by real insights, not vague praise.

Step 4: I send smart nudges at the right time

I keep track of who you’ve been working with — based on your meetings, project tools, and commits — and give you a gentle nudge when it’s a good moment to share feedback.

I connect with your tools — like your calendar, project tracker, or GitHub — so you don’t have to remember to give feedback.

I’ll catch the moment and remind you with just the right prompt.

Bonus: I help you grow over time

Over time, I help you spot patterns — what you’re known for, what’s improving, and where to focus next. All private. All for you.

I fit right into your workflow

I work where work already happens. Connect the tools you use every day, and I’ll nudge you at the right moments; after meetings, milestones, and meaningful interactions.
