What we do
Four disciplines, one delivery team
No handoffs between agencies. Strategy, design, engineering and operations sit in the same room and ship on the same cadence.
Applied AI & data
Retrieval systems, forecasting models and LLM-backed workflows — evaluated properly, and shipped into real products.
Product design
Interfaces that feel obvious. Research, prototypes and a design system your engineers can actually build from.
Security & compliance
Threat modelling, penetration testing and audit readiness for SOC 2, ISO 27001, HIPAA and GDPR.
Modernisation
We move legacy monoliths to something maintainable — incrementally, with the business running the whole time.
Managed operations
24/7 monitoring, incident response and a named engineer who already knows your architecture by heart.
Why Basalt
Senior people, doing the actual work
You meet the engineers who write your code on day one, and they are still there at launch. No pyramid staffing, no rotating juniors, no account manager translating between you and the build.
- Fixed, senior-only pods of three to six people
- Weekly demos on real environments — never slideware
- Every repository handed over with docs, tests and runbooks
- Transparent burn: you see the same board and the same budget we do
- Post-launch support included for ninety days, always

How we work
A process with no black boxes
Four stages, each ending in something you can click, test or deploy.
-
01
Discover
Two weeks of interviews, architecture review and risk mapping. You leave with a costed plan, whether or not you hire us.
-
02
Design
Clickable prototypes and a technical spec, validated with real users before a line of production code exists.
-
03
Build
Two-week sprints, demoed live. Continuous deployment from sprint one, so nothing is ever hiding.
-
04
Scale
Load testing, observability and a handover your in-house team can genuinely run without us.
Testimonials
What our clients say
Basalt replaced a payment core we had been afraid to touch for six years. They shipped it in fourteen weeks with zero customer-facing downtime.
Daniel OkaforCTO, Lumenpay
The rare partner that pushes back. They talked us out of two features in the first month, and the product is far better for it.
Priya RaghunathanVP Product, Orbital Health
Our internal team inherited the codebase and was productive in under a week. I have never been able to say that about an agency handover before.
Marcus FeldHead of Engineering, Kestrel
