Aztro Labs — Software laboratory
We develop modern, powerful and highly scalable software.
Aztro Labs is a software laboratory: web, mobile and AI on a modern stack, built to scale. One dedicated squad per client: in-house senior engineers, full time and 100% on your product, never split across clients like every other agency, and on your calls and in your code reviews. Obsessed with your product's growth, measured on its numbers. MVP live in one month, daily commits in your own GitHub repo, cloud on your account, a client portal with live staging and the deploy log, the same team after launch. One invoice a month; cancel anytime.
Our own products: Resortz, Healti, Rocketz, Fudies and Eventz.Our own products: Resortz, Healti, Rocketz and Eventz.
The mathematics behind the work: Big-O complexity, Euler's identity, Kepler's third law, Bayes' theorem, gradient descent, Shannon entropy, the Schwarzschild radius and the logistic function.
Seventeen reasons the squad is yours.
Everything below is standard on every plan. None of it is an add-on.
01
“Six months and $80K later, we still had no MVP.”
43% of software projects run over budget and 48% run late. (PMI, Pulse of the Profession 2018, 4,455 project professionals: 43% of projects over budget, 48% late, 9.9% of every dollar lost to poor performance.)
What we are judged on
Obsessed with your product and growth.
Your growth is the only reason to keep us on the account. Agencies get paid to close tickets; we are judged by what your product does after launch: users, revenue, uptime. So we bring ideas you did not ask for, push back on the ones that will not move the numbers, and read your dashboards like our own.
Senior judgment from day one
Scope, priorities and architecture settled in week one, so you will not redo them in six months. “Done” is defined in writing before we start, and a senior reviews every pull request.
An MVP in one month
Discovery and architecture in week one, core flows on staging by week two, real users by week four. You can click through staging the whole way, so nothing is a surprise at the end.
Daily progress, GitHub access
Every working day leaves commits you can read, in a repo you have full access to from the first one.
Highly scalable architecture
Designed so the hundredth customer costs you less than the first, and the first traffic spike is a non-event.
02
“Seniors sold it. Juniors built it. Then they moved on.”
The large outsourcers lose 14–28% of their engineers a year; whoever sold the project rarely finishes it. (Annual attrition at TCS, Infosys, Wipro and HCL: 17–28% in 2022 and 14–15% in 2025 (The Register; quarterly results).)
Senior engineers, not account managers
The people who decide the architecture are on your calls and review your code. No layers between you and the people building your product.
In-house senior engineers, full time
40 hours a week each, on your product. In-house, not freelancers; not a slice of someone else's calendar.
Continuity
The same team for the life of the engagement. No rotation, no handoffs; the domain knowledge stays with your product.
100% focused on your business
Every other agency splits each engineer across two or three clients and bills every one of them as full time; our founder spent seven years inside US software agencies watching it happen. Here one squad works on one product, all day, every day, and never on anyone else's.
10+ years of experience
Building and running software across healthcare, hospitality, e-commerce, restaurants and events.
Hire without the hiring
No recruiting, no benefits or payroll taxes, no hiring risk. One monthly invoice; cancel whenever you want.
03
“We saw nothing for months. When we left, they kept the code.”
Transparency is the quality clients value most in a vendor: 54%, ahead of trustworthiness and proven results. (Deloitte Global Outsourcing Survey 2022, 150+ executives: transparency 54%, trustworthiness 41%, understanding of the business 40%, proven results 36%.)
Active communication, every day
Your Slack or Microsoft Teams, with the squad in it all day. Questions, ideas and decisions get answered in minutes, in the channel, not parked until the weekly meeting.
Cloud dev environment from day one
Monitor progress and results, and use each feature in the cloud as it lands. From day one, not at the end.
Transparency as a product
A client portal with live staging, the deploy log and progress, plus a one-page written report every week. Not promised in text; visible.
Your code, in your repo, under your org
Created in your GitHub organization on day one, with a signed IP assignment in the service agreement. Yours in law and in practice: nothing to migrate, nothing to ransom.
Cloud infrastructure experts
AWS and Azure, on your own account: we set it up, automate the releases and keep watch, so nothing is tied to us.
What happens after launch
Operation, monitoring, support and continuous improvement. That is where you capture the value, and where most agencies disappear.
Five disciplines. Proven on real products.
Every engagement starts with your operation, not with a template. Each discipline below is shown on a product we built — open any of them and look around.
SaaS and web apps
SaaS platforms, internal tools, customer portals and marketplaces. Tested and load-checked before launch, and structured so the tenth feature is as easy to add as the first.

Fudies AI on iOS and Android, one app for five roles: diners scan the table QR, waiters take orders, the kitchen runs its display, cashiers close, managers see every branch.
AI Engineering
Agents that plan, call tools and finish the job, not chatbots that answer and stop. Retrieval over your documents and databases with every answer grounded and cited; vision and voice in the same pipeline; models fine-tuned or distilled when a frontier model is too slow or too costly; and the repetitive work around them automated end to end. Every system ships with an eval suite, guardrails, tracing and a cost ceiling, so it can be changed on Monday and trusted on Tuesday.

- RAG & knowledge retrieval
- Vision, voice & OCR
- Fine-tuning & distillation
- Evals & guardrails
- MCP tool servers

Eventz ↗Events · production ERP
A sales agent that quotes and books over WhatsApp and Messenger: tool calls against the catalog and the calendar, prices computed by code and never by the model, every turn traced, and an eval set of real conversations replayed before any prompt or model change ships; lead scoring, voice-note transcription and bank statements read by vision alongside it.
Resortz ↗Hospitality · property management system
‘Ask your hotel’ as retrieval over live PMS rows, every answer carrying the figures it came from; a rate advisor whose suggestions pass a human approval gate before they reach the OTAs; a concierge quoting real availability on the website and WhatsApp; digests that write their own narrative.
Healti ↗Healthcare · financial back office
Document intelligence: licenses, DEA certificates and CVs extracted into typed records with a confidence per field and low-confidence fields routed to a reviewer; questions answered over the roster; OIG and SAM exclusions screened as a nightly batch, on a schedule and not a prompt.
Fudies ↗Restaurants · POS and operations SaaS
AI narratives on every sales, product, operations, tips and inventory report, for every branch, produced as queued jobs with retries, deduplication and a cost ceiling per tenant, mailed daily, weekly and monthly; Uber Eats orders, WhatsApp updates and ticket printing run as jobs around the clock.
Rocketz ↗E-commerce platform
Agent-to-system handoff: orders an AI sales agent closes on WhatsApp or Messenger enter the sales board through a typed partner API, priced from the catalog and idempotent, so a retried tool call never creates a second sale.
APIs & integrations
We connect what you already run: payments, billing, CRM, ERP and, in healthcare, EHR, clearinghouse and payer systems. New software talks to old from the first sprint, and every connection is documented and monitored so a silent failure upstream does not become your problem at month-end.
