Pain

B2B teams often waste time turning company information into usable prospecting lists. The hard part is not just collecting data; it is making it useful enough for sales teams to trust and repeat.

Solution

Qualifiquei organized company signals into lead workflows: discover companies, enrich basic context, save prospects and make list building more repeatable for commercial teams.

How I approached it

I built and operated the product from zero, learning where SaaS focus, pricing, support, ICP clarity and data quality matter more than adding another feature. The lesson is about operator judgment as much as engineering.

Operating lessons

  • A data product wins only when users trust the repeated workflow, not just the dataset.
  • Pricing and support reveal product-market fit faster than polished dashboards do.
  • Founder-led SaaS work forces trade-offs between features, support load and acquisition quality.

Next focus

  • Carry the data-product lessons into IrishTalents and other market-intelligence products.
  • Use the experience as proof of building, selling and operating software under real pressure.
