CO2 AI

Designing with AI for sustainable decision-making.

See the work

Client. An enterprise sustainability platform, born at BCG, now a startup driving large-scale decarbonization.

Approach. Companies struggle with Scope 3 emissions — often the majority of their carbon footprint. Existing tools are complex and data-heavy, making it hard for teams to understand, simulate, and act in real time.

Delivery. Rethought the experience so sustainability data feels intuitive, actionable, and strategic: a new AI layer to model Scope 3 data, simulations across supply chains, and a clearer navigation and packaging model across CCF Measure, PCF Measure, Reduce, and Product Ecosystem.

AI that interprets Scope 3
An AI-driven experience that reduces complexity and highlights actionable insights — live, contextual interpretation instead of data overload.
Simulation for R&D, procurement, and sustainability
Flows that let teams model material and supplier scenarios, compare trade-offs, and move forward without leaving the platform.
Navigation and product packaging
A cohesive suite so enterprises find the right module at the right time, instead of a fragmented set of tools.

Due to confidentiality, visuals use adapted marketing assets rather than final product designs.

Skylark

A SaaS platform to launch and grow streaming services.

See the work

Client. Skylark is an API and CMS for video products — handling the complexity so content owners can build world-class streaming platforms.

Approach. As Lead Product Designer for over five years, Sonjal was part of spinning Skylark out of Ostmodern into a funded product (£2M). The work ran from research through design and build to launch and evolution.

Delivery. Design requirements from internal teams and user research, a live customer-profile model, a new editorial ecosystem, and data-driven automation that reduced effort for curators while increasing engagement.

A live customer profile
A living diagram of each client's editorial needs — capturing nuance so the team could enhance engagement with precision.
A fresh ecosystem
Navigation and data-model structure aligned to global standards. Quiet innovation: small shifts that make a large difference in daily CMS work.
Editorial experience & automation
Skylark v2 gave curators a robust arena to create pages and components independently, plus filtering, automated lists, and analytics that recommend the next action.

OHO.live

Enhancing interactive live streaming for reality TV.

See the work

Client. An interactive streaming platform for live reality TV — viewers engaging with real-time content on iOS and Android.

Approach. User-centered design with iterative testing: research showed the audience stretched to 35–40, not only 18–25. The work focused on context, timeline, guest discovery, and a hub for related shows.

Delivery. A homepage structured for catch-up and discovery, narrative timeline and recaps, moderated live chat, interactive polls that shaped the show, and dedicated pages for guests, categories, and presenters.

450k downloads · 2M hours streamed
During a two-month live program the app attracted over 450,000 downloads and more than two million hours of content — design as a growth lever, not decoration.
Real-time participation
Live chat and short- and long-form polls gave fans a voice in daily challenges and eliminations, while revealing which guests had the most dedicated followers.
Catch-up without losing the plot
Timeline, highlight reels, and structured VOD so users joining mid-live could follow the storyline and find guest information instantly.

03 — Approach

How the work actually happens.

Bonjour — the designer behind Sonjal. Passionate about solving complex problems through creativity, the practice leads from research and design through build, launch, and evolution.

01
Shared ownership
Solo or embedded with your team — the work is collaborative from the first conversation to launch.
02
Show, don't document
Work-in-progress through prototypes and presentations, shared with every stakeholder. Not decks that collect dust.
03
Systems, small and large
Reusable components whether the brief is one feature or a full design system.
04
Fast iterations
Swift loops through the creative process until something simply works.
05
Prototype into production
Front-end and no-code fluency to make ideas tangible — then hand them to engineering without translation loss.
06
Design as a playground
No fear of discarding an idea. More options, better judgment.
