Lember

Lember is a Poland-based software development company founded in 2015 by Victoria (CEO) and Konstantin (COO), both engineers who had 16 years of combined industry experience before starting the firm. The company now operates offices in Ukraine and Poland with 50+ tech specialists on staff. Over the past decade, Lember has completed more than 150 projects, serving clients in the UK, Canada, and across North European countries. The company focuses on custom software development, SaaS products, staff augmentation, and modernizing legacy systems—work that spans fintech, healthcare, logistics, travel, and digital marketing.

Lember's founding principle was balancing design, technology, and business goals. The founders built the company around longer-term partnerships rather than one-off projects; their average engagement now runs 2.5–3 years, and 65% of clients return for additional work. Early wins came from a 3D animation platform for a London design agency and rapid growth on Upwork. The first enterprise contract arrived in 2018 for a US travel and hospitality client. By 2020, the firm was expanding into AI and data-driven components alongside complex integrations. In recent years, work has shifted toward active SaaS platform maintenance and modernization, with ongoing focus on reliability and scalability.

Services and capabilities

Lember organizes its offerings into six main service lines. Custom software development covers web, mobile, and backend applications. The SaaS development team builds products from scratch, delivers MVPs for fundraising, and maintains active subscription platforms. Their SaaS methodology uses modular monolith architecture initially, deferring microservices until complexity warrants the shift. They handle cloud setup and optimization across AWS, GCP, and Microsoft Azure, including autoscaling and cost-tuning. Staff augmentation lets clients hire Lember engineers directly into their teams—developers choose whether Lember manages the engagement or the client retains full control. Legacy modernization helps businesses migrate from no-code or outdated tools, preserving data while improving speed and flexibility. Cloud development and migration includes DevOps managed services, containerization, and security hardening. AI integration covers both off-the-shelf models and custom ML solutions for forecasting, NLP, and personalization.

Lember also offers analytics implementation, third-party API integration, performance optimization (code cleanup, caching, debugging), and post-launch support and maintenance. For SaaS projects specifically, they help with product-market fit validation, analytics and dashboarding, and long-term team augmentation. The company serves startups, SMEs, and enterprises, with particular strength in fintech (payment orchestration, ledger systems), logistics (inventory management, 3PL fulfillment), healthcare (patient care platforms), and marketing automation (CRM, messaging campaigns).

Notable work

Lember's case studies show real client names and measurable outcomes. OnePageCRM, a CRM system with automated workflows, was built for sales and marketing automation. Simasti, a subscription-based messaging platform, has been a long-term partnership; Lember continues to improve the product while maintaining stability "critical for a system used daily at scale," per client feedback. DocStribute, a fintech SaaS product for regulated financial communication, launched ahead of investor timeline commitments. 3PL Fulfilment, a platform connecting e-commerce businesses with fulfillment partners, required rapid Node.js and React specialist recruitment. Giglaty, a real estate platform for property search and agent coordination, went from concept to launch smoothly and came in under budget. Suppli is a warehouse management system for small and mid-sized businesses. Tripety helps travelers plan itineraries with budgeting, document storage, and route optimization. Homecare Mittelland Plus provides patient care, consultation, and nutrition supply coordination in one interface. Persuasion Systems built a clinic platform for patient understanding and personalized care delivery. All projects cited strong communication, flexibility with requirement changes, and quality of execution in testimonials.

How they work

Lember responds to inquiries within 23 hours and offers free detailed estimation. Clients can connect directly with business development managers and technical specialists, not just sales. The company handles hiring, contracts, compliance, and tax management on behalf of the client. Engagement models include fixed-price projects, dedicated teams, and T&M (time and materials) arrangements. The firm emphasizes transparency in contract terms and keeping clients informed at every development stage. Project approach depends on company size, industry, required solutions, and timeline; Lember analyzes competitors and visits key facilities (production lines, sales points) to understand the business before choosing a development model. For SaaS, they advocate starting with modular monolith architecture and single-repo setup to speed iterations, deferring complexity until it's proven necessary.
