Proposal example
Illustrative founders and collaboration scenario.

Start with the kind of help you need.

A second opinion, specialist work, a shared experiment, and a cofounder search involve different commitments. Name the relationship before you write the invitation.

A peer

Exchange a perspective on one decision. Useful when you need another founder to challenge an assumption.

A collaborator

Work together on a defined first task. Agree on the contribution and outcome each person expects.

A specialist

Ask for expertise with a clear scope. Discuss availability, fees, and how the work will be reviewed.

A potential cofounder

Explore long-term ownership and responsibility. Skills are only one part of compatibility.

An introduction starts a conversation. Both people choose what comes next.

Simplified our first-project flow. Still testing whether the labels are clear.

Illustrative public work

Read the work behind the profile.

Look for a product, update, or practical example that connects to the help you need. Public work gives your introduction context and helps you ask a more relevant question.

Relevant skill

What has this person shown that relates to your task?

Current focus

Does the proposed exchange fit their product and stage?

A respectful first step

Check the contact options and interests they make available.

A proposal they can actually answer.

Explain why this founder, what you need, and what you can contribute. Bound the first exchange so the recipient can assess it without designing the whole project for you.

Example private proposal

From:
Noah
To:
Mira

Hey Mira — your signup critique helped me spot a question in my own onboarding.

Would you review the first-project flow in my SaaS? I’m trying to learn where a new user hesitates.

In return, I can review the implementation of your signup prototype.

Could we each spend up to 30 minutes and exchange written notes on one flow? If that’s too much, we can start smaller.

Proposed scope · both founders still need to agree.
  1. 01

    Why you

    Reference relevant work.

  2. 02

    The request

    Name one workflow and question.

  3. 03

    Your contribution

    Make the exchange concrete.

  4. 04

    The first step

    Propose a manageable commitment.

Acceptance opens the conversation.

On Buildside, a founder can accept or decline a private collaboration proposal. When it is accepted, continue privately to agree on the task, timing, and material to review. Acceptance does not grant product access.

Illustrative accepted proposal

Mira: Happy to review one flow. Which task should I try?

Noah: Create a first project with sample data. Let’s confirm the scope before we start.

The task

Agree on one workflow.

The time

Suggest a manageable amount.

The output

Written notes on the agreed scope.

Trade useful work, not vague favors.

In this example, Mira reviews Noah’s first-project experience, while Noah reviews Mira’s signup implementation. Each person returns observations tied to the agreed task.

Before making it bigger, review the exchange.

Did both people deliver the agreed work? Were the notes specific and communication clear? Decide together whether to repeat the exchange, change the scope, or stop here.

Put the first exchange in writing.

Use the collaboration brief to describe the task, contribution, time, and expected output. Add a short review of what happened before proposing more work.

How do I find founders with complementary skills?

Explore profiles and public work that relate to your task. Use Founder Matches as a starting point, then check relevance and mutual interest directly.

What belongs in a collaboration proposal?

Explain the task, why you chose that founder, what you can offer, and a small first step. Agree on scope before work begins.

Is a collaborator the same as a cofounder?

No. A collaborator can join a bounded exchange. A cofounder relationship involves broader responsibilities and needs a separate, deliberate discussion.

Find the person for the next small step.

Bring your context. Offer something useful. Decide together.
