Four updates.
One story worth following.

Prelaunch SaaS marketing starts with something useful to share. Walk people through the problem, your progress, a real limitation, and the next opportunity to take part. Each update gives your waitlist link a reason to exist.

01

Where do your receipts end up? 🧾

I’m exploring how freelancers keep project expenses together. What did you do with the last receipt you needed to find?

02

One project. All its expenses. 🛠

Here’s the first project view. I’m checking whether grouping receipts helps people review costs before sending an invoice.

03

Manual first. Smarter later. 👀

The prototype still needs manual categories. I’m sharing that upfront so early subscribers know what to expect.

Freelance communities

Talk about project expenses where freelancers already discuss their workflow.

Existing conversations

Follow up with people who asked about the problem and welcome an update.

Buildside founders

Share progress with builders. Check whether interested founders also fit your customer profile.

A signup starts the conversation.

A growing list records interest. To understand its quality, look at who responds, who tries the product, and who returns to use it. These are different commitments, so review them separately.

  1. Joined

    Does this person fit the intended audience?

  2. Replied

    Can they describe the problem in their own work?

  3. Tried

    Did they complete a relevant task?

  4. Returned

    Did they come back when the need arose?

Planning framework · record these observations in your own worksheet.

Plan the story.
Give the waitlist a home.

Use the four-update plan to shape your next posts, and the signup-quality worksheet to keep track of what you learn. On Buildside, a product waitlist gives interested visitors a dedicated page to join.

Share public progress updates as you build. When you’re ready to follow up, export your signup list and use your own email workflow.

Before your first signup

How do I grow a SaaS waitlist without an audience?

Start with relevant conversations in places your intended customers already participate. Share a useful observation or prototype update, explain who the product is for, and link to a clear waitlist page when it fits the discussion. Follow community rules and ask before sending a promotional link in a private conversation.

What should I share before launch?

Share the problem you are investigating, a real prototype decision, what is still limited, and what someone can expect after joining. Keep each update grounded in work you have actually done. You can revisit the four-update sequence as the product changes; it does not require a fixed posting schedule.

Does a large waitlist prove people will pay?

No. A signup records interest in the promise on your page. A relevant reply, a completed test, continued use, and a purchase are different commitments. Look at who joined and what they do next, and investigate willingness to pay separately.

Can I export my Buildside waitlist?

Yes. Owners can download a CSV of signup names, email addresses, and join dates from a product waitlist. Use the exported list in your own follow-up workflow, in line with what subscribers expected when they joined. Buildside’s waitlist does not imply an automated email sequence.

Your launch story starts before launch day.

Show what’s taking shape. Invite the people it could help.
