Micro-SaaS for paid media buyers: how to validate an idea with 10 customers before coding

Recurring pain point

Identifying a recurring pain point in the market is the first step. Talk to paid media buyers and e-commerce operators to find out what problems they face. Ask about challenges with campaign management, audience targeting, ad optimization, or performance reporting. The pain point needs to be specific and frequent, because that’s what ensures the solution you build will have real demand.

Landing page + pre-sale

Create a simple landing page that presents your Micro-SaaS idea. Use tools like Unbounce or Leadpages to make the process easier. The page should include:

• A clear headline about the proposed solution
• A description of the pain point you’re solving
• The benefits of your solution
• A CTA (call to action) to capture leads or drive pre-sales
• An email collection form

After that, launch a pre-sale where the first 10 customers can secure early access. Offer a discount or exclusive benefit to anyone who signs up for the pre-sale.

Pricing

Set a competitive price that reflects the value your solution delivers, but is also affordable for your target audience. Do a quick survey of potential customers to find out how much they’d be willing to pay. Monthly price points between R$ 49,90 and R$ 149,90 are common for SaaS solutions for paid media buyers. Keep in mind that a price that’s too low can devalue the product, while a price that’s too high can scare off potential customers.

No-code mvp

To validate your idea without a big investment in development, use no-code tools like Bubble or Adalo. Build an MVP (Minimum Viable Product) with only the essential features. The goal is to test market acceptance, not to create a finished product. For a Micro-SaaS MVP, focus on one feature that solves the pain point you identified, like campaign tracking or report generation.

Validation signals

After launching the landing page and pre-sale, watch for these validation signals:

• Number of pre-sale signups
• Landing page conversion rate (ideally above 20%)
• Qualitative feedback from early users
• Engagement with your communications (email opens and clicks)
• Reactions on social media and in discussion groups

If you can get 10 customers willing to pay and receive positive feedback, that’s a strong sign your idea has potential. Now you can start building the full product with more confidence.
