Working with the client

*Important: this is not project delivery work — it is work with the client specifically, and it is not in the estimate or commercial proposal; it is what we do to raise the product’s chance of successFrom “I ordered a product” to “I understand my business better than anyone”At the start the client came with an idea and a budget; at the finish they left with a ready business and entrepreneurial instinct that usually takes years. Defence.investments systematically transferred a mindset with which they can dissect any new project on their own. We broke their fintech niche into atoms: payment mechanics, scoring, antifraud, user flows — and most importantly, taught them to link every technical detail to profit and risk. Then we went further: we gave the client “strategic vision” — the ability to see adjacent opportunities and threats beyond the original plan. Multi-hour personal consultations with the director cemented that knowledge, removed limiting beliefs, and helped formulate not only a product strategy, but a life strategy for the entrepreneur. The result is a person ready to build a business without us, yet knowing that in any hard moment they have an “operating partner.”Our goal is not just development — it is our client’s success.

Design goals:

•RAISE SUCCESSFUL DEAL VOLUME BY 60% THROUGH A REFINED CUSTOMER JOURNEY

•MAKE THE PRODUCT SHOWCASE A MARKETPLACE SO INVESTORS CHOOSE FASTER AND 50% MORE OFTEN

•INCREASE CLIENT RETENTION ON THE PLATFORM

•MAKE ANALYTICS EASIER FOR THE USER

Design results:

•A SINGLE WINDOW FOR THE INVESTOR: RIGHT AFTER LAUNCH THE PLATFORM OFFERS MANY PROJECTS, SAVING TIME SEARCHING FOR OPPORTUNITIES

•CLEAR NAVIGATION: CATEGORIES AND FILTERS HELP QUICKLY FIND THE RIGHT STARTUP OR FUND, IMPROVING INVESTMENT EFFICIENCY

•DEAL TRANSPARENCY: ALL PROJECT INFORMATION (GOALS, TIMELINES, ROI) IS AVAILABLE ON THE PLATFORM, STRENGTHENING INVESTOR TRUST
