Services
We listen to your day-to-day, advise where AI can help, and put in motion what your business needs.
Where AI fits
AI isn't one single thing. Here are some day-to-day problems where it's already helping businesses like yours.
Philosophy
Two Japanese ideas guide how we bring artificial intelligence to your business. They aren't ornaments: they are the difference between AI that unsettles and AI that welcomes.
おもてなし
AI that anticipates
Your agent serves the way you would on your best day: it gets ahead of what the customer needs, with warmth, around the clock. Hospitality, not a robot.
ものづくり
AI made to measure
No generic templates. Your agent is shaped by the data, tone and detail of your business, until it feels like yours.
We live that culture of service. That's why our AI feels human: because it's made by human hands. Sumi, right here, is the proof.
Process
Calm guidance, from start to finish.
We listen and understand your business, your customers and your goals.
We shape a tailored proposal, tending to every detail.
We adjust together until everything feels exactly right.
We publish your project and stay by your side after launch.
Success stories
What owners say after letting their website work for them.
“People message us in Japanese and Spanish; the agent replies to each in their own language and books the table without us losing a single query.”
“We used to lose appointments by not replying in time. Now the site books on its own, at any hour, and we show up to a full schedule.”
“The agent recommends dishes and takes takeout orders like one more of the team. Customers don't even notice it's an AI.”
“Having the menu and reservations in one place, with someone who answers instantly, changed our day to day. We got back to cooking.”
No strings attached
We'll prepare a demo of your website and your agent —free and with no commitment— so you can see how yours would feel. If you love it, we make it real. If not, the idea is yours to keep.
Frequently asked questions
And if a question remains, ask Sumi or message us on WhatsApp.
We connect your business with artificial intelligence: we build custom websites, apps, and AI agents, and we advise where AI helps you most —customer support, sales, scheduling, repetitive tasks. The website or agent is a way in; the diagnosis comes first.
No. Seika was born in Japan —that's where our care and craft come from— but we work with businesses in any country. Advice and development are remote.
It depends on the project, because everything is custom. The first conversation and a demo of your own are free and with no commitment; once we understand what you need, we give you a clear estimate.
An assistant that serves your customers 24/7 in your business's tone: it answers questions, books appointments, recommends, and guides the sale. You can try Sumi right here or see demos by industry in the agents section.
We speak Spanish, English, Japanese, and Vietnamese. And the AI agents reply in each customer's language, whatever it is.
Talk to Sumi, our AI, or message us on WhatsApp. We'll set up a no-commitment demo and advise where AI fits into your day to day.
