Products
Software for decisions that matter
Optimization software for planners, developers and quantum teams. Every product runs on one engine: the 4colors Optimizer.
Scheduling records that stood almost 20 years, and over 50% fewer two-qubit gates than Qiskit.
Start from the work you do
Each product is made for one kind of team. Pick yours to see what fits.
For planners
Planning apps
Explore all planning applicationsReady-made apps for production, shift and project planning. An AI assistant sets each one up with you.
| Production scheduling
Takt
Production schedules that meet due dates with fewer changeovers.
Re-plans the whole schedule when a rush order lands or a machine stops.
| Workforce planning
Roster
Rosters that cover every shift and keep every rule.
Re-plans the week within your working rules when someone calls in sick.
| Project scheduling
Stride
Project plans that finish sooner with the people you have.
Re-plans every project that shares a team when one of them slips.
For software teams
Optimization software
Advanced scheduling algorithms and one API, for the software you build.
4colors Optimizer for Scheduling
New records on a public scheduling benchmark, beating results that stood almost 20 years.
Scheduling algorithms inside your own software, through Python or the API.
Developer Platform
One API for every solver: submit from any language and follow better answers live.
APIs, documentation and examples, from the first test to production.
For quantum teams
Quantum software
All quantum toolsBetter circuits for today's devices, and a strong classical reference for every QUBO model.
4colors Quantum Compiler
Over 50% fewer two-qubit gates than Qiskit, in the same time.
Searches placements, routes and native gates for your device, from Qiskit, Python or the API.
4colors Optimizer for QUBO
10 s on one million variables for the quality other solvers need over 30 s to reach.
A classical solver for QUBO and Ising models, and a like-for-like reference for quantum hardware.
Under the hood
One engine under every product
Takt, Roster, Stride, the Optimizer for Scheduling, the Optimizer for QUBO and the Quantum Compiler all run on the same engine: the 4colors Optimizer.
The 4colors Optimizer brings together mathematical optimization, constraint-based reasoning and specialized search. Each product puts it to work on one kind of problem.
Powered by
4colors Optimizer
Original search algorithms, tested on demanding benchmarks and run to your time budget.
Explore the 4colors OptimizerDecisions that span departments?
Production, staffing, packing and routing decisions shape one another. Optimized together, they reach plans that no single-department plan can.
Evaluate the software
Free trial
Start a 15-day free trial of Compiler or QUBO, with plans for individual developers and teams.
Early access
To explore scheduling and planning applications, request early access.
Optimization proof of concept
A working prototype on your own constraints, measured fairly against your current plan or solver before you commit.
