01
Trading & execution
Terminals, OMS/EMS, broker bridges, algorithmic execution and risk engines. Built for low latency and for the day the market gaps and every assumption breaks at once.

We build the systems finance runs on.
Seventh Sense is a senior engineering team across finance, software and AI. We design, build and harden the platforms where speed, correctness and trust decide who wins.
Proof by demonstration
You’re scrolling through the proof.
This page runs a real-time rendering engine, a live simulation and multi-script typography at sixty frames a second, in a browser, with every word still accessible. We hold client work to the same standard. The difference is that client work also has to clear an audit.
Seven verticals
If it moves money, we have built it.
02
Market data & quant infrastructure
Tick capture, normalization, storage and research platforms. Backtesting that agrees with live trading, because both run on the same code.
03
Exchanges, brokerage & fintech
Matching engines, wallets, ledgers, onboarding and reporting. Platforms that hold customer money and are engineered like it.
04
Digital assets & on-chain
Custody integrations, smart-contract systems, indexers and chain analytics. We work at the protocol level and build products people can actually use.
05
AI agents & LLM systems
Agents that act in financial workflows, with retrieval, tool use, evals and guardrails. Models that cite their sources and stay inside their permissions.
06
Compliance, forensics & RegTech
Monitoring, investigations, case management and reporting. The engineering behind Case Base, applied to your obligations.
07
Tax, accounting & treasury
Ledgers, reconciliation, tax engines and treasury automation. The engineering behind Zeppelin, applied to your books.
+ Interface
Product design & frontend
Interfaces for dense data: terminals, dashboards and sites like this one. Designed and engineered by the same team, so nothing is lost between the mockup and the metal.
Engagement models
Four ways to work with us.
Build
Delivered.
A fixed-scope product or platform, delivered by a dedicated senior team with clear milestones and a system you own outright at the end.
Embed
Alongside you.
Our engineers join your team, ship inside your process and raise the bar for everyone around them.
Audit & rescue
Stabilized.
Architecture, security and performance reviews. When a critical system is failing, we stabilize it first and then fix the cause.
Retained R&D
On standby.
A standing lab for research-heavy problems: models, strategies and prototypes, with a direct line to the people building them.
Process
The seven-step ascent.
- 01
Signal.
A conversation about the problem, under NDA if you prefer.
- 02
Scope.
A written brief with the risks, the options and a price.
- 03
Architect.
Designs and decisions, reviewed with your team before anything is built.
- 04
Build.
Working software every week, demoed by the people who wrote it.
- 05
Harden.
Tests, load, security review and failure drills.
- 06
Launch.
A controlled rollout with monitoring in place on the first day.
- 07
Evolve.
Support, iteration and a handover your team can run with.
Standards
What every client gets.
- Senior engineers only. The people you meet are the people who build.
- You own the code, the IP and the infrastructure.
- NDAs by default. Client work is never shown without permission.
- Security reviewed at every milestone. See our security standards.
- AI used where it measurably helps, and never on your data without consent.
Priced to the problem.
We don’t publish rates, because no two systems carry the same risk. Every engagement starts with a written scope and a fixed price or a capped retainer. You’ll know the cost before we write a line of code.
Request a proposalHow quickly can you start?
Most engagements start within two to four weeks of a signed scope. Audits and rescues can start sooner, because a failing system can’t wait. [NEED: confirm]
Do you work with startups?
Yes, when the problem is hard and the money is real. We work with funded startups, trading firms, exchanges, institutions and public agencies.
Can you work with our existing team and stack?
Yes. Embedding is one of our engagement models, and we’ve shipped in most modern stacks. We’ll recommend changes only when they pay for themselves.
Who owns the work?
You do. Code, IP and infrastructure transfer on payment, with documentation your team can run with.
