AI-native product studio

We build software,
then we run it.

SoftStackers is a studio building a portfolio of AI-native products. Software we design, ship, and operate ourselves. Different markets, one operating engine: small senior teams, AI at the core, built to last on our own infrastructure.

HaloSilver

Catches scams before they cost someone you love.

Runs quietly on a parent's or loved one's computer, reads what's on screen for scam signals with AI, and sends the family a calm heads-up: romance grooming, gift-card pressure, fake tech-support, remote-access. You see the alert, never their screen.

The HaloSilver screen on a monitored computer: The light is on. Quietly watching for scams. There's nothing you need to do.

SonicStacker

Custom AI songs for the moments that matter.

Tell it the story (the dog's name, the inside joke) and it writes and produces an original song in about ninety seconds. Birthdays, weddings, memorials, just because. Every track original, never trained on protected works.

PolicyChanges

AI policy-change monitoring for billing teams.

Sweeps every payer (UnitedHealthcare, Aetna, CMS, BCBS and more) every 24 hours, then uses AI to surface each change with its impact level, affected billing codes, effective dates, and the exact action a practice needs to take. Before it hits revenue.

A PolicyChanges alert: a Medicare reimbursement change flagged HIGH, showing effective and identified dates, affected specialties, and a plain-language summary of the payment rule.
§ 02Ask the studio· answers from what we've shipped

Ask about the products, the AI work, or working with us.

It answers from what we've actually built, and says so when it doesn't know. Leave an email and it passes you to the team.

§ 03How we operate· the connective tissue
01

AI-native, not AI-added

Every product starts with the model at the center: agents, retrieval, and tuned models doing real work. Not a chat box bolted onto old software.

02

We operate what we ship

We don't hand off and walk away. We run our products in production on our own AWS infrastructure, and keep improving them for years.

03

Small, senior, fast

No layers, no handoffs. The people who design a product are the people who build and run it. That's how a whole portfolio comes from one small team.

§ 04AI engineering· what we actually do with models

The AI work behind the products.

We are not consultants writing about AI. Every capability below is running in production in something you can go use today.

01

Agentic systems

Multi-step agents that plan, call tools, and recover when a step fails. Guardrails, retries, and human handoff where the stakes are real.

02

Retrieval (RAG)

Hybrid search, deliberate chunking, reranking, and grounded answers with citations. Tuned against real user queries, not a demo corpus.

03

Tiered model routing

A cheap high-recall model screens every candidate; a stronger judge model rules on what survives. Most of the quality at a fraction of the inference cost.

Evals and observability

Golden datasets, offline eval suites, and regression gates before release. Every production model call traced and reviewable.

05

Workflow automation

AI that removes whole steps from an operation rather than sitting beside it. Measured by work eliminated, not messages sent.

Vision and audio

On-screen understanding and generative audio running on real hardware — including a desktop agent light enough for a ten-year-old PC.

§ 05 · COMPANY

A product company with years of shipping behind it.

SoftStackers has built and operated production software since 2019. Founded by Ben Rodrigue, we spent years shipping and running systems for other companies. That engineering depth now goes into a portfolio of our own AI-native products.

We also take on a small number of applied-AI engagements each year for select partners, and remain an AWS Select Tier Partner. Talk to us →

§ 06 · CAREERS

Builders who want to own the whole thing.

We're a small senior team shipping real products to real users. If you want range (design, build, and operate AI-native software end to end) we're always talking to exceptional people.
