NYC-based software and AI studio
Custom software and AI, built for your business.
We build websites, web apps and platforms, internal tools, and integrations between the tools you already use, plus automations and AI assistants that run on your own data. Every project is custom and scoped to how your business works.
Now taking on a limited number of founding clients.
Services
What we build
From a full platform to a single automation, we build what your business needs. Each project starts with one problem that costs you time or money, and we scope the work around it.
Web apps and platforms
Marketplaces, customer portals, booking systems, and the other software your business runs on, designed and built around how you work.
Websites that convert
Clear, fast websites that explain what you do and make it easy for visitors to call, book, or buy.
AI assistants on your own data
A chat assistant for your customers or staff that answers from your own information first: products, policies, specs, and records. It stays inside guardrails, shows clear disclaimers, and runs under usage caps so costs stay predictable.
Automations and integrations
Connect the tools you already use so information moves between them without retyping, and routine steps run on their own with a person reviewing what matters.
Dashboards and plain-English reporting
Upload a sales export and ask questions in plain English, like “What was our best-selling product last quarter?” You get answers with charts, a quick summary of totals and top sellers, and a suggested action plan.
Internal tools for your team
Tools for support, hiring, and operations: a support agent that answers from your own documents and hands off to a person when unsure, hiring help from job post to candidate emails, and paperwork processing that pulls out key fields and flags what is missing.

Aquacellum: an AI-powered marketplace for the aquarium hobby
We designed and built Aquacellum for Steve, a rice fish breeder in New Jersey. It brings species research, a breeder marketplace, and an AI care guide together in one place.
- Client
- Steve, rice fish breeder
- Location
- New Jersey
- Status
- Live in production, version 5
What we built
Species database
A searchable database of 508 freshwater and saltwater species, with care ranges and tank sizes.
Marketplace
Breeder storefronts, orders, and live auctions, including club auction nights.
Ask Echo, the AI guide
Powered by an engine called Poseidon, Echo answers from Aquacellum's own species data (temperature, pH, size, temperament) before general knowledge. It checks whether fish can live together and shows the numbers on a card, and it takes voice input.
Guardrails
- No medical diagnoses
- Clear disclaimers
- An hourly usage cap to control costs
Community
The Reef, clubs, and a leaderboard.
Installable app
Works offline, for tank logs at home and at shows.
Developer API
A developer API.
Results
Live in production on version 5, refined over five releases with the client's feedback. Breeder storefronts are actively listing and selling.
Demos
More we've built
A few examples of what we've built. Every client project is custom. These demos run on sample data and are not public, so we walk through them with you live on a call.
InsightFlow
Ask your sales data questions
Upload a sales spreadsheet and ask about it in plain English. It answers with charts, sums up totals and top products, and drafts an action plan. The sample data is a fictional three-location coffee shop.
SupportForge
Support answers from your own documents
A support agent that answers from a business's own policies and product manuals. Each reply shows its confidence, and questions it cannot answer well are handed to a person with a summary.
TalentFlow
Hiring help, from job post to reply
Turns rough notes into a job post with screening questions, scores PDF resumes against the role with strengths and red flags, and drafts thank-you, offer, and decline emails. The current version is set up for golf course hiring.
ProcessPilot
Paperwork in, clean data out
Reads invoices, receipts, and onboarding forms, pulls out the key fields with a confidence score for each, and flags problems like a missing signature. Each document then moves through review to a suggested next step, such as an email draft.
PersonaForge
Customer personas and campaigns
Groups a customer list into four to six personas with pain points, buying triggers, and preferred channels, then drafts email, social, and SMS campaigns for each. The sample data is a skincare customer list.

Process
How it works
Free discovery call
20-30 min
We learn how your business runs and what you need built, and tell you plainly what we would build first and whether it is worth doing.
Founding-client pilot
Fixed scope, 2-4 weeks
We build a focused first project, or the first phase of a bigger one, at a reduced founding-client rate in exchange for a case study.
Launch
Go live
We put it in front of your team or customers, show everyone how to use it, and fix what comes up in the first weeks.
Monthly support and improvements
Ongoing
We keep it running, keep costs in check, and improve it as your business changes.
Founding-client spots are limited. Every pilot or first phase is fixed-scope, so you know what you are getting before we start.
