The Defense Innovation Unit moves fast. OpStop tracks every open DIU Commercial Solutions Opening (CSO) and challenge solicitation daily — and surfaces the ones that match your company first.
A Commercial Solutions Opening (CSO) is DIU's primary acquisition vehicle — an Other Transaction (OT) that lets the DoD rapidly contract with commercial companies without traditional FAR-based procurement rules.
DIU CSOs skip the lengthy procurement process. From proposal to prototype contract can happen in 60–90 days. Prototype contracts can transition to production awards worth hundreds of millions — sole-source, no competition, under 10 U.S.C. § 4022.
GovWin doesn't track them. HigherGov doesn't cover them. OpStop does.
CSOs can close for new proposals within 30–60 days. Companies that check DIU's website weekly miss opportunities that were open for 3 weeks. OpStop alerts you the day a new CSO posts.
DIU's own website lists solicitations in reverse chronological order with no scoring, no filtering by your tech area, and no relevance ranking. OpStop matches every CSO to your company profile before you ever see it.
A DIU OT prototype contract is the on-ramp to sole-source production awards worth 100x the prototype value. Companies that engage DIU early and consistently — not just when they happen to notice a solicitation — win the production contracts.
