Lunar Logic

Lunar Logic is a 20-year-old product development studio based in Kraków, Poland. Founded in 2004 with early commercial work on Ruby projects for the United Nations Japan, the company has since worked with ING Bank, Philips, and a roster of fintech, green tech, and B2B SaaS clients across 15 countries. Today it focuses on founders and early-stage businesses, offering services from discovery and validation through product scaling. The firm has completed 200+ projects and holds a 4.9/5 rating on Clutch.

Services and capabilities

Lunar Logic's core offering is a four-stage product development process. The first stage—Discover and Validate—uses targeted experiments and workshops to test business assumptions early. The second, Shape and Design, applies user-centered design to turn validated ideas into actionable solutions. Development happens in short cycles with real-user testing (Design Thinking Process). The final stage, Measure & Refine, analyzes performance data and user feedback to optimize and scale.

Within this framework, the company delivers product discovery and MVP ideation, product design, web development, mobile development (native iOS and Android), systems integration, and AI-assisted development. According to their claims, discovery work can save clients up to 70% on initial development costs. A baker software client reportedly went from a failed launch to sustainable recurring revenue; a founder expected a 3-month project but completed validation in 2 weeks, radically changing direction.

For process optimization, Lunar Logic focuses on custom software and smart integrations. They report typical outcomes of 40% operational cost reduction. For growing products with performance bottlenecks, they optimize architecture and systems—one case study cites 2x faster system performance.

Notable work

The most detailed case study is Hypo (HypoGuide), a Swiss fintech founded by Mathias Joss. Lunar Logic partnered with Hypo for 9 years across three phases: first as a mortgage comparison tool, then pivoting to Hypoauktion (an auction model that reversed lending power dynamics), and finally scaling through FinanceScout24's 2019 acquisition. The engagement involved design, product development, and consulting. The team grew from 4 to 13 engineers during the post-acquisition phase. Hypo's success—transforming a 2-3 hour in-person mortgage process into a 5-10 minute online experience—demonstrates Lunar Logic's approach to fintech disruption.

Other named projects include HabitatMap (green tech, 17-year partnership), Funding Circle (fintech), Done by One, OrderNova, Hubert's Candidate Portal (AI/hiring), and Urb-it (sustainable logistics). Pest Pulse is quoted as saying Lunar Logic "stepped up to address other needs" beyond scope and "responded quickly as the project changed."

How they work

Lunar Logic emphasizes direct collaboration without middle-management layers. Clients work directly with engineers and product consultants. A 30-minute discovery call clarifies business needs; a 4-day discovery workshop maps assumptions and value opportunities. The discovery process applies design thinking to move systematically from problem understanding to solution validation. The firm claims this methodology has helped startups reduce validation costs by 60%.

The company operates office-based from Kraków (Al. Zygmunta Krasińskiego 17/3). Teams work directly with clients and maintain flexibility on team size and technology stack. Pricing is not publicly listed; engagement typically begins with a discovery call and workshop. For early-stage work, the firm uses rapid prototyping and "Wizard of Oz" MVPs (automated processes combined with manual expert oversight) to validate core assumptions before full automation.

Team and credentials

Founded in 2004, Lunar Logic operates with approximately 50+ engineers based on the scale of work across 15 countries and 200+ projects. The firm highlights 50% female engineers on staff. Named team members include Sebastian Strycharz (Android Developer), Monika Śmiałko (iOS Developer), and Tomek Rusiłko (Product Consultant & Team Lead). The company runs a 14-year internship program and participates actively in Rails Girls Kraków, a community initiative for underrepresented developers.

The firm emphasizes "radical transparency" on salaries and finances, direct client collaboration without bureaucratic layers, and fairness as a core operating principle. No ISO, SOC 2, or formal third-party certifications are mentioned in the source. Lunar Logic holds a 4.9/5 rating on Clutch (rating count not specified in source, but described as based on multiple client reviews).
