Tailor-made software when your ERP, CRM or spreadsheet doesn't fit how you actually operate.
We connect your systems and automate what off-the-shelf tools can't handle. Scope, timeline, and price locked before we start.
When off-the-shelf isn't enough?
Three signs that point to custom software.
Data scattered across 3+ places
ERP, CRM and spreadsheet hold pieces of the same process. The team exports CSV every week to cross-reference by hand.
A business rule the tool won't let you configure
Commission policy, tax math or approval criteria don't fit the tool's editor. Operations end up fixing it manually.
Audit or regulator requires a process trail
Compliance, IRS or a professional council asks for what was done, when, by whom. Off-the-shelf exports a loose spreadsheet, not an auditable trail.
Who we work with (and who we don't)
This might work for you if you're...
- ✓A founder with a validated idea who needs to turn it into a running product, without hiring a team
- ✓A company with a repetitive manual workflow that wants to automate with AI
- ✓An operation that needs a specific internal tool and doesn't want to allocate internal dev resources
- ✓A small-to-medium business wanting to apply AI to a concrete problem without knowing where to start
Probably not a fit if...
- ✗A project that needs a team of 5+ devs in parallel
- ✗A contract that requires open-ended time allocation without scope
For these cases, we can recommend partners.

Why Chiarelli
Three differentials that separate a project that works from one that stays a slide.
AI that works in production, not in a demo
There's a gap between 'making a ChatGPT demo' and 'running AI in production without leaking data, hallucinating, or breaking when the client's spreadsheet has 50,000 rows.' That gap is where most projects die. It's exactly where we work.
You talk to the builders. Always.
No account manager. No PM in between. No rotating squad. Technical decisions, deadlines, scope, production bugs — everything goes directly through the founder. You gain speed. And when something goes wrong, nobody needs to 'align internally' before responding to you.
Project risk is ours, not yours
Scope locked before we start. Fixed price, no hourly billing. 90-day warranty post-delivery (three times the market standard). If something breaks, we fix it. You don't need to become an AI expert to assess whether the solution will work. That decision is ours, and so is the risk.

What we deliver
Four project models with scope and price defined before we start.
Automation
We replace repetitive manual processes with custom automations. Cross-system integration, document processing, specific business rules.
- →Bank statement reconciliation against the accounting spreadsheet
- →Integration between a Brazilian ERP (TOTVS, Senior, Bling) and external systems without a ready connector
- →Unstructured document processing (invoice, contract, report) in recurring workflows
- →Automation of regulated processes involving sector-specific business rules
AI Agent
We build agents that operate where templates fall short. Legacy systems without an API, technical-regulatory knowledge bases, cross-referencing multiple internal data sources.
- →Agent that operates inside a legacy system without a public API
- →Assistant with a technical knowledge base of your domain (equipment manuals, regulatory standards, historical reports)
- →Agent that crosses 3+ internal data sources to answer business questions nobody can answer quickly today
Internal Application
We build the internal tool your operation needs: dashboard, control panel, internal app, custom workflow system.
- →Executive dashboard
- →Mobile app for field team
- →Internal management system
Deep Discovery ($2–3k, 2–3 weeks) is a prerequisite. Risk inversion applies to the execution phase after Discovery.
Full Digital Product
We build the production-ready digital product: SaaS, mobile app, AI-applied tool. Delivered running, with infrastructure, authentication, billing, admin panel.
- →Custom B2B SaaS
- →Platform with AI applied to your niche
- →Verticalized marketplace
First projects under this format. Deep Discovery required before scope and price are locked.
