What Millisecond Software does

Millisecond Software, LLC is a Seattle-based, privately held and bootstrapped software company founded in 1995 that builds the Inquisit platform, a precision toolset for administering psychological and cognitive experiments and assessments. The platform consists of three core SKUs: Inquisit Lab, a standalone Windows/Mac desktop application for in-person testing with local data storage; Inquisit Web, a cloud service that extends the same experiments to web browsers and mobile devices (iOS, Android) with millisecond-accurate timing via native system APIs; and Inquisit EDU, a separately priced cloud service for undergraduate and high school classroom research. The platform's distinguishing technical assets include hardware-level precision timing, native integration with neurophysiological systems (EEG, fMRI, eye trackers) via TTL signals, configurable regional data storage in the US, EU, Japan, and Australia, offline mobile data collection, and a bundled content library of 926 customizable psychological tests covering cognitive, clinical, social, developmental, organizational, personality, educational, sports, and forensic psychology.

The company monetizes through a hybrid licensing model: one-time perpetual licenses (with three years of free updates) for Inquisit Lab ranging from $475 for a single seat to $4,495 for a perpetual departmental license, plus subscription tiers for Inquisit Web ranging from $395 (two-month single) to $3,495 perpetual. Campus-wide institutional licenses are sold by direct quote, and the Inquisit EDU SKU is priced per academic term and student count ($595-$1,295 for 15-45 students). It also offers fee-based custom programming services for novel experimental tasks. Distribution is primarily direct (online store, phone, email) supplemented by a global reseller channel, with marketing reliance on the public test library, multi-version documentation, and an active user forum.

Millisecond serves a horizontally segmented customer base including academic and university research labs, clinical research organizations, neuroscience labs, market and behavioral economics research firms, UX/HCI research teams, and HR/employment screening organizations. The company states it serves 3,934 institutions worldwide and is cited in thousands of peer-reviewed articles. It operates with 11-50 employees, is headquartered at 1205 E Pike St, Ste 2H, Seattle, WA, and reports no external equity funding, acquisitions, or leadership changes in the supplied materials.

Direct peers

• PsychoPy: PsychoPy is a widely adopted open-source psychology experiment builder. It competes directly with Inquisit Lab for academic research budgets and is freely available, making it a strong alternative for cost-sensitive customers.
• jsPsych: jsPsych is a leading open-source JavaScript framework for running behavioral experiments in a web browser, competing with Inquisit Web for online experiment deployment among academic researchers.
• Psychology Software Tools (E-Prime): E-Prime is the longest-standing direct commercial competitor to Inquisit Lab for psychological experiment design, offering a Windows-based authoring environment and runtime engine used in academic and clinical research worldwide.
• Gorilla Experiment Builder: Gorilla is a commercial web-based platform for building and running online behavioral experiments. It directly overlaps with Inquisit Web in functionality and target customer — academic research labs running online cognitive studies.

Regional players

• SoSci Survey: SoSci Survey is a popular German-language online survey and experiment platform. It overlaps with Inquisit Web in academic use cases but primarily serves the German-speaking academic market rather than competing globally.

Broad incumbents

• Cambridge Cognition: Cambridge Cognition offers validated cognitive assessment tools for clinical trials and healthcare, with deeper regulatory compliance than Millisecond. It competes for the clinical trial portion of Inquisit's customer base while operating at a larger scale.
• Qualtrics: Qualtrics is a broad survey and experience management platform that integrates with Inquisit. It is an ecosystem partner rather than direct competitor, but its expanding research suite overlaps with Inquisit's survey-embedded experiment use cases.
• Cogstate: Cogstate provides computerized cognitive testing for clinical trials and healthcare research. It serves the same clinical research segment as Inquisit's CRO customers but with a stronger regulatory and commercial footprint.
• Pearson Clinical (Q-global): Pearson Clinical offers a broad portfolio of digital clinical assessment tools including Q-global. It overlaps with Inquisit in clinical and neuropsychological assessment use cases but operates at much larger enterprise scale.

Emerging players

• Testable: Testable is an online behavioral experiment platform with browser-based execution, positioned as a more affordable web alternative to Inquisit Web for academic researchers running online psychology studies.
