Leadmarten

2026
Context

Personal project (SaaS), built end-to-end as Scrum Master and Technical Product Owner.

Problem

Job hunting depends on waiting for companies to post openings. Most opportunities are never advertised (the "hidden market"), and sending spontaneous applications by hand is slow and tedious.

Solution

Leadmarten automates outbound networking to companies. The user defines an activity and an area, the platform pulls real companies from Google Maps with their contact details, and sends personalized spontaneous applications by email (CV attached, spaced-out sending to protect sender reputation), with CRM-style tracking of each company's status. It finds the right companies and knocks on their door before the opening is posted.

Result

In production and used by a closed group of real users, with an active roadmap. Managed with documented agile methodology.

Role

Scrum Master & Technical Product Owner / end-to-end development.
