Stop burning runway on features that don't convert
The problem
Users drop off during onboarding
You're acquiring users but losing them before they ever convert. Users abandon after the first session. They're not seeing value fast enough, getting confused during onboarding, or hitting friction you didn't anticipate.
Struggling to convert users to revenue.
Your product has activity. Users are exploring features, using the app. But not paying. You're stuck with hundreds of free users and low subscriptions, and you don't know what's blocking conversion.
Shipping lots of features, no growth progress
Your team is working hard, engineering is shipping every sprint. Features keep landing. But revenue isn't moving. You're burning $$$ on building things that don't translate to growth, and the runway is shrinking.
Whats actually broken?
Growth doesn't fail randomly. It breaks at specific points in your user journey.
I use the Product-Market Fit Pathway — a diagnostic framework that identifies which signal is blocking revenue:
Acquisition → Are the right users finding you?
Activation → Do users reach value quickly or drop off confused?
Retention → Do users come back because the problem recurs?
Revenue → Will users pay, or is this solving a nice-to-have?
Referral → Do users tell others, or use it silently?
Most teams guess which one is broken. I help you diagnose it with evidence, then validate the fix before you spend another £50K building
How I help
Build features that converts. Verified with data.
I combine product strategy, behavioral validation, and systems thinking to help you connect user behaviour to business outcomes. You'll know exactly which features drive subscriptions and which ones are just noise. Every decision becomes data-informed.
-
Identify which part of your journey is broken.
Through validation rapid testing, I help you replace guesswork with clarity using data. -
Test features with real users before spending £50K building and hoping. This ensures you’re building something people genuinely want to use, pay for, and recommend.
-
By focusing on what not to build, validating early, and sequencing work correctly, I help you avoid wasted engineering effort and costly rework. Your burn rate drops, your runway extends.
-
Prioritise features by conversion impact. Identify realistic revenue paths early — whether that’s pricing signals, value exchange, or monetisation experiments. This makes your product more resilient and more compelling to investors.

Axel Hunter, founder Devin.no
I’ve worked with Tshili multiple times since meeting her at Shell in London, and she’s one of the best UX designers I’ve ever collaborated with. I’ve recommended her to clients and brought her into companies. Consistently the first person who comes to mind when I see teams struggling with UX.

Tshili is an exceptional UI/UX expert who builds designs that truly convert. Each weekly phone call saves us weeks of time. Without her, we would be pondering over UX fragility and wondering why churn is high. Tshili is creative but still always puts the customer first in her design, which is essential in high-stakes projects.
