Our expertise
Everything it takes to ship, under one roof
Six practices that work as one team, so nothing gets lost in the handoff between design, build and the day you go live.
Mobile Apps
Native and cross-platform apps for iOS and Android with offline-first behaviour and release pipelines that hold up.
- Swift & Kotlin
- React Native
- App Store delivery
AI Engineering
Retrieval, agents and model-backed features wired into real workflows — with evaluation baked in from day one.
- RAG pipelines
- Agent tooling
- Eval harnesses
Blockchain
Smart contracts and decentralised applications, audited end to end before a single value transfer goes live.
- Solidity & Rust
- Wallet UX
- Audit prep
Cloud & DevOps
Infrastructure as code, observability and CI/CD so shipping on Friday afternoon stops being a gamble.
- AWS & GCP
- Terraform
- Zero-downtime deploys
Support & Care
Long-term maintenance, security patching and performance work from the same engineers who built the system.
- SLA response
- Security patching
- Cost tuning

Talk to an engineerHow we work
Four steps, no surprises
The same rhythm on every engagement — you always know what is happening this week and what lands next.
01
Discover
We map the problem, the users and the constraints before a line of code exists. You leave with a written scope, not a guess.
02
Design
Interface and architecture are drawn together, so what looks right on screen is also cheap to build and safe to change.
03
Build
Two-week increments with a working deployment at the end of each. You see progress in the product, never in a status deck.
04
Launch & scale
We handle release, monitoring and the quiet weeks after — tuning performance and cost while your users settle in.
Inside a Factumsoft squad
2:48We're ready to help
A team that scales with you, not around you
Start with one engineer and grow to a full squad, or hand us a fixed scope and a date. Either way the work is senior, documented, and yours from the first commit.
- Senior engineers only — no juniors billed as experts
- Weekly demos against a working deployment
- Your repositories, your cloud accounts, your code
- Scale the team up or down at the month boundary
Client stories
What teams say after we leave
The measure of the work is not the launch — it is whether the system still makes sense a year later.
Factumsoft replaced a six-month internal roadmap in eleven weeks. The handover documentation alone was worth the engagement.
Dana WhitfieldVP Product, Northline LogisticsThey pushed back on half of our original spec — and they were right. We shipped something smaller, faster, and far more used.
Marcus AdeyemiFounder, Cadence HealthThe AI retrieval layer they built answers support tickets with citations. Our deflection rate went from 12% to 41% in a quarter.
Priya RaghunathanHead of Support, TesselClean contracts, a real audit trail, and a front end our non-crypto users can actually operate. Rare combination.
Deploys used to take a person and an afternoon. Now they take four minutes and nobody watches. That is the whole review.
We have worked with four agencies. Factumsoft is the first that treated our codebase as something they would have to live in.
