Stop burning runway on features that don't convert
Problems I solve
Users drop off during onboarding
You're acquiring users but losing them before they ever convert. Users are getting confused during onboarding, not experiencing the value of the product fast enough, and you struggle to convert users to revenue.
Struggling to convert or retain users
Your Your GTM is working, but retention is broken. Your free users aren't converting and your paid ones aren't staying. Your product has activity. Revenue is coming in but the numbers underneath it are not sustainable for growth.
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 — and no amount of GTM spend fixes a broken product experience underneath it.
I use the Product-Market Fit Pathway diagnostic framework to identify 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, or did you solve a one-time problem?
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
Grow subscriptions, reduce churn, build for long term revenue
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.

David Asare, founder Marchcroft
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.
