SellSea.ai
An AI sales platform that proves the product in the first conversation.
Brand identity and full-stack product development for an outbound AI voice platform, spanning a live call demo, configurable agents, campaigns, lead management and call review.
The product premise
Hear the product before reading the pitch.
SellSea is built around one direct interaction: enter a mobile number and receive a real call from the AI agent. Visitors can hear it qualify interest, respond to the conversation and move towards a useful next step before being asked to trust a feature list.

Brand identity
A signal that feels active, connected and in motion.
Four flowing forms create the SellSea mark. They read as voice signals, live conversation and two sides moving towards one another. A high-energy blue carries that idea across the wordmark, interface and marketing experience, balanced by quiet navy type and pale technical grids.
The experience
The call is one moment in a larger workflow.
The interface had to make the voice agent feel immediate while keeping what happens before and after the call legible. Lists, notifications, scheduling and outcomes give each conversation a place in the team's day-to-day work.
Call
Move from a list to a live conversation.
Contacts can be added individually or imported in bulk, then called directly or worked through a paced campaign.
Review
Turn the conversation into the next action.
Every completed call returns an outcome, transcript, summary and duration so the team can follow up with context.
Full-stack development
One connected system, from browser to phone call and back again.
The product combines a public marketing experience, authenticated workspace, API, relational data and a live voice worker. Each organisation deploys a versioned agent configuration, and every call is tied back to the exact version that ran it.

Product language
Explain a complex product in outcomes people recognise.
The public experience moves from the live call into practical capabilities: natural conversations, objection handling, meeting booking, summaries, configuration and analytics. The language stays close to the work an outbound team already does.
What shaped the work
Designing the promise and the proof together.
Make the demo the argument
The strongest way to explain a voice product is to let somebody hear it. The first interaction is the service itself, with the surrounding page there to build understanding.
Keep configuration in plain English
A sales agent can be technically complex without asking the user to think like a developer. Seven clear fields turn business knowledge into a versioned, deployable agent.
Design beyond the call
The conversation is only useful when the result reaches the team. Campaign state, live viewing, summaries and follow-up were treated as the product, not supporting administration.
