LINDO Systems

What LINDO Systems does

LINDO Systems, Inc. is a privately held Chicago-based software vendor founded in 1981 that develops mathematical optimization solvers used by enterprises, academic institutions, software developers, and consulting firms. Its product family is built on a shared core of industrial-grade algorithms covering linear, nonlinear (including global optimization for non-convex models), integer, and stochastic programming, with proprietary components such as a Global solver that guarantees global optimality, a Barrier/Interior Point solver, and Multistart capabilities. The portfolio is delivered through three core interfaces: What'sBest!, an Excel add-in for spreadsheet-based modeling; LINGO, a standalone set-based modeling environment; and LINDO API, an embeddable solver library available across Windows, Linux, MacOS, ARM, and Android with bindings for Python, Julia/JuMP, R, MATLAB, and ODBC data sources.

The company monetizes primarily through one-time perpetual software licenses (priced $195–$4,995 per single user, with volume discounts up to 30%) supplemented by tiered upgrade fees, optional solver add-ons (Barrier, Nonlinear, Global, Stochastic), negotiated site licenses for organizations with 20+ users, discounted educational licenses, and runtime licenses for ISVs embedding LINDO into third-party applications. Go-to-market is hybrid: a product-led model with free limited-capacity downloads, a sales-led model for enterprise and site licenses (1-800-441-2378), and channel partners/distributors for international markets. Customer base is reported as thousands of companies worldwide, with Solver Suite reportedly used at over half the Fortune 500; named customers historically include P&G, Bridgestone/Firestone, Efes, the U.S. government (CNA, START treaty analysis), the National Cancer Institute, and Bangkok Dusit Medical Services.

LINDO has operated continuously without external venture or private equity funding since 1981 with a lean 11–50 person organization. Recent strategic emphasis has been on expanding platform reach (ARM/Apple Silicon, Android), modern developer interfaces (Python, Julia, R, MATLAB, REST API, Docker), and integration with VS Code, including a LINGO Copilot AI-assisted code-completion extension. Educational channels — INFORMS student competition sponsorship, free research licenses, and large user-contributed models libraries — form a sustained pipeline for both academic adoption and long-term enterprise customer cultivation.

Revenue model

1. Software Licenses (Perpetual): LINDO generates primary revenue through perpetual software licenses for LINGO, What'sBest!, and LINDO API products. Customers purchase once and own the license, with optional maintenance/support contracts.
2. Capacity Upgrades: Customers can upgrade to larger capacity versions of the same product, paying the price difference within 60 days or difference plus $25 after 60 days.
3. Software Options/Add-ons: Additional solver options (Barrier, Nonlinear, Global, Stochastic) can be added to base versions for expanded model-solving capabilities.
4. Site Licensing: Commercial and educational site licenses negotiated on a case-by-case basis, typically for organizations with more than 20 users.
5. Runtime Licenses: Discounted runtime licenses for users of turnkey optimization applications created by third-party developers using LINDO products.
6. Educational Licenses: Discounted educational licenses for students and educational institutions, restricted to educational instruction and research. Six-month renewable research licenses available at no charge.
7. Software Updates: Update fees apply when new releases are issued: 20% of standard license price for previous release, increasing by 10% for each additional release gap.

Core offering

LINDO Systems develops and sells mathematical optimization software, providing a family of solvers for linear, nonlinear, integer, stochastic, and global programming problems. Customers access these solvers through three product interfaces: What'sBest! (Excel add-in), LINGO (modeling environment with a set-based modeling language), and LINDO API (embeddable solver library for developers), plus a bundled Solver Suite entry-level package. The software is used for production planning, transportation, finance, portfolio allocation, capital budgeting, blending, scheduling, inventory, and resource allocation decisions.

Product overview

LINDO Systems offers a portfolio of mathematical optimization software centered on three core products: What'sBest! (Excel add-in), LINGO (standalone modeling environment), and LINDO API (embeddable solver library). All three share the same underlying solvers for linear, nonlinear, integer, stochastic, and global optimization. What'sBest! targets Excel users who want to build optimization models directly in spreadsheets. LINGO provides a comprehensive modeling language with set-based capabilities for large-scale models. LINDO API gives developers programmatic access to embed optimization into custom applications. The Solver Suite bundles all three products at entry-level capacity. The company also offers VS Code extensions including a LINGO Language extension and LINGO Copilot AI assistant.
