We build the AI assistantyour business can count on.
A bilingual team from the Des Moines metro. Since 2020 we have designed brands, websites and campaigns. Today we also build Stack Mind, an AI assistant that saves you time, and a person always approves what matters.
Sinsajo Creators builds AI assistants for small businesses. Its product, Stack Mind, answers customers at any hour, follows up on every lead and keeps what the business knows in one place: Hanna talks to customers on the website and on Telegram, and BOSS remembers the business and answers by text or voice. Each client has their own installation, so data is never mixed. Based in Pleasant Hill, Iowa (Des Moines metro), fully bilingual in English and Spanish, with a person approving anything important.
People, data and AI, working as one team.
That sentence is the whole company. Everything we make, from a logo to an AI assistant, exists so that a small business can serve like a large one without losing the person behind it.
How we got here
Four chapters, in order. Each one is still part of what we do; the newest is where we are going.
- First
A design studio
Brand identity, graphics and communications for businesses that needed to be understood in English and in Spanish.
- Then
Websites and campaigns
Sites, social media and advertising that had to work as hard as the brand, and be measured.
- Now
AI assistants
Hanna answers customers and follows up. BOSS remembers what the business knows. A person approves anything important.
- Next
Stack Mind for every client
Your own installation, set up around how your business works, instead of a pile of apps that do not talk to each other.
What we do
Six ways in. All of them end in the same place: a business that is easier to run.
- Brand and identity
- Logos, visual systems and the words a brand uses, designed to work on a phone screen and a billboard alike.
- Websites and web applications
- Fast, bilingual and ready for AI search engines, so customers find you and can reach you.
- Social media and content
- Editorial calendars, video and copy that a real person approves before it goes out.
- Hanna, who answers your customers
- Answers on your website and on Telegram, finds out what each person needs, saves their contact and follows up, in both languages.
- BOSS, the memory of your business
- A searchable memory of clients, decisions and documents, so the business stops depending on who remembers.
- Implementation and support
- We set it up with you, train your team and stay available after launch.
How we work
Four rules we do not bend, because each one has cost someone a client at some point.
AI prepares. A person authorizes.
Nothing that cannot be undone happens without a person approving it: a message to a client, a payment, a deletion. The assistant proposes; you decide.
Bilingual by design, not by translation
English and Spanish are written separately by people who live in both. A client should never feel they got the second version.
We only promise what works
Stack Mind does not run a company without people, and it is not a script that repeats canned answers. We tell you plainly what it does for your case.
Local and reachable
Based in Pleasant Hill, serving the Greater Des Moines area and clients across the US and Latin America. A phone number that a person answers.
