built end to end.
Solidinput is the practice of Kristoffer Sørensen — over a decade of digital marketing married to modern full-stack engineering. Strategy, software, and operations stay connected instead of being handed between separate vendors.
Based in Estonia. Building measurable growth systems, internal tools, and production web applications for Nordic and EU businesses that need software they can actually run — not concept pieces.
Strategy that stays connected to implementation.
Two disciplines, one studio. Marketing decisions inform what gets built; engineering decisions inform what can actually move a number. Both sides operated by the same person.

Technical SEO, content structure, and search-intent work aimed at qualified demand instead of vanity traffic.

for practical digital work.
Solidinput is intentionally a one-person studio. Direct communication, clear ownership, and less distance between decision and implementation.
The marketing side covers SEO, performance optimization, and lead-generation strategy. The software side focuses on production-grade web applications — SaaS platforms, CRMs, compliance tools — using React, Next.js, and Supabase.
Every project starts with understanding the business problem. Whether it's increasing organic traffic or building custom software from scratch, the goal is the same: deliver measurable results with clean, maintainable work.
Bring a concrete
business problem.
Send the context, the current bottleneck, and what a useful outcome would look like. You will get a direct reply from the person doing the work.
For new projects, partnerships, or a single specific question — the fastest channel is direct email. Replies are usually inside one working day.
