Safrow

Safrow Labs

We follow questions until they turn into things.

Some of our questions became software and apps you can use today. Others are about AI, physics and space, and we're still working on them.

The questions behind what we build.

Each entry pairs a question with what we built to answer it. Some are out in the world, some are still on the bench.

Can you run an SEO audit across a million pages?

Answer

CodoSEO

We hit that wall ourselves. Running SEO across our own portfolio of products meant auditing more pages than our tools could handle, so we wrote CodoSEO: a Rust crawler you can point at as many pages as you need, with 44 checks, a 0–100 score, and --fail-on critical to stop a release when SEO breaks. Then we open-sourced it, because other teams have the same problem.

Can you build and maintain SEO at scale?

Answer

RankOrg

It's how we run our own. Every Safrow product's SEO goes through RankOrg: it researches the niche, maps topic clusters and publishes one SEO and GEO-optimised article a day. We pointed it at rankorg.com from day one, on a brand-new domain, and the domain rating went from 0 to 30 in two months.

What if your forms could hold a conversation?

Answer

Rioform

Rioform builds agentic forms. Instead of a fixed list of fields, an AI agent talks with each visitor, picks the next question from their last answer, and scores the lead before your team sees it, with a summary of what was said.

How do you find investment opportunities beyond a single market?

Answer

StockTrio

We look through three arcs: what the market is doing, what the business actually earns, and what it's worth today. StockTrio runs that process at scale, and we've used it for a year on our own investment portfolio. It starts with US stocks on the NYSE and Nasdaq and is built to grow past one market.

Can a wellness app help without collecting a thing?

Answer

Neubo

Yes. Neubo has no account, no sensors and no analytics. Mood check-ins, breathing exercises like the physiological sigh and box breathing, and focus games with no scores all live in a local store on your iPhone.

What would a Stoic keep on their phone?

Answer

Stoic

A passage, an exercise and a question. Each morning Stoic gives you one passage from Marcus Aurelius, Epictetus, Seneca or Musonius, one of twelve timed exercises such as the Dichotomy Sort, and a short check-in. It takes under two minutes.

How do you prove where a product came from?

Answer

Supply Chain Tracker

Write every hand-off to a ledger nobody can quietly edit. Manufacturer, distributor and retailer each record their step on a Proof-of-Authority blockchain, so anyone can trace a product back to where it started. We built it in Solidity and Go and published the design as a peer-reviewed paper.

02Our R&D center

Tetratomic

Deep tech · exploring quantum · coming soon

Tetratomic is our deep-tech startup, for problems that take years rather than sprints. Right now we're exploring quantum computing. The products above fund it, and tetratomic.com opens when there's something real to show.

03How we fund ourselves

Our products fund our research.

Safrow is independent. We build software and apps that people find useful, and what they earn goes into research on AI, physics and space. That research comes back as papers, open-source code and the next generation of products, and the loop starts again.

    Build products

    Software and apps that solve one clear problem well.

    Customers keep them alive and tell us what to fix next.

  3. 03

    Revenue funds R&D

    What the products earn goes into the lab.

  4. 04

    Research becomes products

    Papers, open source, and the next thing we build.

We publish what we learn.

We've committed to publishing our research as we go. So far that means one peer-reviewed paper and a stack of engineering notes, with our first annual report in the works.
