Smart technology.Real engineering.

We're a senior software engineering team. We help you work out what you actually need, choose the right technology and build reliable systems that fit the tools and people you already have.

Tell us what you need to solve

The first conversation is free. You talk to the engineers who would do the work.

AI proposes.You decide.

Sendero moves your company's files from file shares, SharePoint Server, OneDrive or Egnyte to SharePoint Online and OneDrive without a hassle, and then stays: it looks after them, tells you when something needs a decision, and turns your Excel files and lists into flows, reports and alerts you ask for in plain words. It proposes deterministic rules you can read, and nothing runs until someone with authority approves.

  • Migrates with permissions and checks every file
  • Looks after your information every night
  • Turns Excel files and lists into flows, reports and alerts
  • Speaks first when something needs a decision

Finance to SharePointOctober 23, 2026
I want to move the Finanzas folder to a new SharePoint site, with its permissions.
Checked what’s installedBrowsed the serverSearched sitesProposed the migration

I found D:\Datos\Finanzas on the FS01 server. I propose a new site, Finanzas, keeping permissions, authors and dates. Creating it only starts the assessment, which reads and writes nothing.

The assessment is ready: 48,210 files, 112 GB. 37 names need fixing for SharePoint and two folders give access to Everyone: those wait for the owner. Migrating takes about 9 hours, so I propose running it at night.

Good engineering starts with choosing the right tool.

Before proposing a new application we look at what you already have and at what each part of the problem needs. Sometimes the answer is AI; sometimes a business rule, an integration or a tool you already pay for.

How to choose between AI and business rules

  • AIto read documents, understand requests and draft answers
  • Business rulesto calculate and decide the same way every time
  • Tools you already pay forbefore a custom application
  • An integrationbefore replacing a whole system
  • Custom softwarewhen the process is what sets you apart
  • A simple architecturethat your team can keep running

Good AI needs good engineering around it.

In Sendero, our assistant for moving, looking after and analyzing information in Microsoft 365, AI does what it does best: it understands your request, explains what it found and proposes the plan as rules you can read. A person approves them, and an engine applies them exactly, the same way every time.

Request: “Move Finance to SharePoint”

  1. Rules engine1Analyzes without writing anything
    Why here

    Volume, permissions, paths SharePoint will reject, duplicates. Counting and checking is work for code, not for a model.

  2. AI2Explains what it found
    Why here

    In plain language, citing Microsoft's guidance, and says which points need a decision.

  3. AI3Proposes rulesyear < 2020 → /Archive
    Why here

    What moves, where, with which permissions and columns, with a before-and-after preview. What comes out of the AI is a rule you can read, never an action.

  4. Person4The data owner answers, the lead approves
    Why here

    Business questions go to whoever owns the data. If they don't answer, the lead decides and the record says who did.

  5. Rules engine5Applies the approved rules, the same way every timeyear < 2020 → /Archive
    Why here

    A permission is never interpreted: it is reproduced exactly, or the file is held until someone decides.

  6. Rules engine6Checks every file and delivers the record
    Why here

    A fingerprint for every file, Office documents compared part by part, and dates, authors and permissions read back from SharePoint.

A consulting case

A client wanted a language model to handle a whole business process, from the calculations to the explanations. We gave each part to what does it best: business rules for the figures, AI to interpret and explain them.

What was proposed

  1. AIA language model calculates the figures

    The same input can produce a different output. Hard to test, hard to audit.

  2. AIThe same model explains them

    An explanation of a number nobody can reproduce.

What we recommended

  1. Rules engineBusiness rules calculate the figures

    Same input, same output, every time, and covered by tests.

  2. AIAI interprets and explains the result

    Natural language where it adds value: reading, summarizing, answering questions.

The result: figures you can test and audit, and AI doing the part where it adds the most.

Deterministic where it matters. Intelligent where it helps.See how Sendero works

Services

Four ways we work with you. Most engagements start with the first one, because that is where we decide together what is worth building.

All services in detail

  • Technical assessment and architecture

    For when you know there's a problem but not what to build, or you've been pitched a solution and want a second technical opinion.

  • Custom software development

    Web applications, products and internal systems, end to end: backend, frontend, integrations, deployment and maintenance.

  • Process automation and practical AI

    Automated workflows and business rules, conversational and voice agents, and AI that interprets and explains. The part that cannot fail stays in code you can test.

  • SharePoint, Power Platform and Microsoft 365

    Connecting systems that don't talk to each other, business data, SharePoint and Power Platform, and with Sendero, migrations to Microsoft 365 and flows, reports and alerts on your data.

Sendero, our product

Sendero is an assistant for a company’s information in Microsoft 365. It migrates files from file shares, SharePoint Server, OneDrive, SharePoint Online and Egnyte with their permissions and checks every file against the original. Then it looks after them every night, tells you when something needs a decision, and turns Excel files and lists into flows, reports and alerts you ask for in plain words. AI proposes; a person decides; an engine applies.

Consulting case

AI to explain, rules to calculate

We moved the calculations into deterministic business rules, covered by tests. AI stayed where it adds value: interpreting the results and explaining them in natural language. A more predictable, more reliable system that is easier to audit, with AI kept where it adds value.

Development case

Repstly, an AI phone receptionist we built

We built Repstly: an AI receptionist that answers calls in natural language, answers questions about the business, books appointments across several calendars with configurable rules, sends confirmations and gives the team an operations dashboard.

Projects for companies in energy, fuels, construction, mining, human resources, finance and law, in the United States and Latin America.

Built together. Made to evolve.

The person who designs your system is the person who builds it and the person you talk to. We document what we do so your team understands it, runs it and does not need us for every change.

How we work
  1. 1

    A first conversation, free

    You tell us what you need to solve. We ask about the process, the people and the systems involved.

  2. 2

    Discovery

    We propose options, including the simplest one, and help you decide which is worth doing.

  3. 3

    Proposal and quote

    Only once the path is clear. Nobody pays before knowing what is worth doing.

Tell us what you need to solve

The first conversation is free. Then we lay out your options and help you pick the right one before we charge anything.

A few lines are enough: the problem, the systems involved, any deadline.
