The platform

Much of what follows evolved from technical necessity and close founder-designer collaboration rather than upfront user research — the founders arrived with working ML technology and domain expertise, not a validated product direction. User feedback shaped refinement along the way, but the initial shape of most of these areas came from translating what the model could do into something professionals could use, not from a research phase that preceded design.

The platform had to support quick risk assessment and detailed investigation without hiding the professional depth users depended on.

A quick look at how these four areas connect in the live product

Company intelligence

The company page became the foundation of the platform. It needed to communicate the current risk assessment immediately while still giving professional users access to the depth behind it.

I structured the experience progressively. The first layer communicated the company's credit rating, outlook, coverage quality, and probability of default. Historical charts then showed whether risk was improving or deteriorating over time.

Users could continue into deeper analysis:

  • Credit spread and its historical movement

  • Term structure across different loan durations

  • Market and sector context

  • Comparable-company risk momentum

  • Comparable probability of default and net worth

  • Sensitivity to inflation, interest rates, oil, technology, the S&P 500, and the U.S. dollar

  • Reference companies and their relevance to the calculation

  • Bonds and other company instruments

  • Related news and events

Portfolio and sector intelligence

Researching one company was only part of the workflow. Credit professionals needed to monitor potentially hundreds of holdings and understand where risk was developing across the portfolio.

I designed portfolio experiences that allowed users to create or import a portfolio and then monitor:

  • Number and value of holdings

  • Portfolio credit spread

  • Changes over time

  • Match rate and unmatched entries

  • Risk momentum

  • Top movers in probability of default

  • Sector distribution and concentration

  • Company and portfolio news

  • Alerts and emerging risk signals

The interface supported two levels of attention. At a glance, users could understand overall portfolio health and identify unusual movement. From there, they could investigate a sector, holding, or event without losing the wider portfolio context.

Sector intelligence added another layer between a single company and the full portfolio. Users could compare industries, follow broader risk movement, and understand whether a company's deterioration was isolated or part of a wider sector trend.

Together, company, sector, and portfolio views transformed Martini from a lookup tool into an ongoing monitoring system.

Scenario and stress testing

Traditional risk reporting is largely retrospective. Martini also needed to help professionals explore how future events could change the credit profile of a company or portfolio.

I designed risk-sensitivity views that connected probability of default to macroeconomic drivers such as inflation, interest rates, oil prices, technology indicators, the S&P 500, and the strength of the U.S. dollar.

The Scenario Builder expanded this into an interactive workflow. Users could describe a hypothetical event — such as an interest-rate shock, market decline, geopolitical conflict, or industry disruption — and refine the resulting macroeconomic assumptions.

Martini then translated those assumptions into projected changes across industries, companies, default risk, and expected loss. Users could compare the baseline with the stressed scenario, identify the most affected holdings, and understand where the portfolio was most vulnerable.

This shifted the experience from passively observing risk to actively preparing for it.

AI-assisted workflows

AI in Martini was never limited to a standalone chatbot. It became a way to access, interpret, and act on the product's existing credit intelligence.

I designed workflows for:

  • Generating company research

  • Finding comparable companies

  • Generating company and portfolio news

  • Uploading financial statements

  • Extracting financial information and producing credit analysis

  • Asking questions about uploaded documents

  • Generating downloadable Excel outputs

  • Running portfolio scenario tests

  • Producing trade ideas

  • Building editable reports

  • Exporting and sharing analysis

Focused improvement

Martini also generated public company-report pages designed to bring organic search traffic into the product. Visitors could read a pre-generated credit report, download it, or continue the research through AI chat.

The pages attracted visitors, but very few started a conversation. I investigated the full report-to-chat journey to understand why. Amplitude showed that only 4 of 50 reviewed visitors started a chat, and just 2 stayed more than ten minutes. Two rounds of rapid testing — 12 participants, then 11, largely the same group — revealed why: people missed the low-contrast chat, the cookie banner covered its prompts, and the surrounding navigation competed for attention. Once users noticed the chat, they understood it — but only 2 of 12 typed a question without prompting.

I introduced a darker chat surface, clickable starter prompts, contextual "Explain with AI" actions, a clearer download CTA, and simpler navigation. I also moved the cookie banner, simplified the first response, and added clear paths back to the report and into follow-up questions.

Outcome

The improvement wasn't a single before-and-after — I tracked it as it happened. In the week the redesign started rolling out, chat sessions went from 2 to 14 to 35 across three consecutive weeks — more than doubling engagement even before every change was fully live. Amplitude confirmed a 112% increase from the pre-change baseline within days. After the full set of improvements went live, Amplitude showed a 625% increase in recorded chat events across the comparison period, and the founder separately confirmed that 80% of all chat engagement on the static pages was now coming from the AI CTAs I'd designed.

Hotjar recordings confirmed that the redesign was working: visitors scrolled further, spent more time with the report, and noticed the chat more consistently. With the discovery and comprehension barriers resolved, the experience created a stronger foundation for deeper AI engagement.

Results

Over four years, Martini.ai grew from an early corporate-credit model into a platform for company research, portfolio monitoring, scenario testing, and AI-assisted analysis.

The company raised a $6M seed round, expanded to more than 3.5 million public and private companies, and later joined BlackRock.

Reflection

Martini taught me that simplifying a professional product does not mean removing its depth; it means revealing that depth in the right order. My role was to connect scores, context, sources, portfolios, and AI workflows into one experience without pretending the underlying decisions were simple.
