OTA

DIU Commercial Solutions Opening (CSO)

DIU's core solicitation vehicle. DIU posts Areas of Interest (specific operational problems) and any commercial entity can respond. It's a competitive, three-phase funnel: solution brief, pitch, full proposal.

  • ~$500K–$10M+ prototype (varies by problem) · Non-dilutive
  • Any individual or commercial entity with an applicable commercial solution; nontraditional contractors strongly preferred. No small-business set-aside.
  • rolling (AoIs posted continuously)

How to apply: Watch DIU's open solicitations, then submit a ~5-page (or ~15-slide) solution brief against a specific Area of Interest. Selected teams pitch, then are invited to submit a full proposal.

OTA

Other Transaction (OT) Prototype Agreement

The contract you actually sign after winning a CSO. Authorized under 10 U.S.C. §4022, it sidesteps most FAR/DFARS overhead — no DCAA audits, lighter IP terms, faster negotiation.

  • sized to the prototype scope · Non-dilutive
  • Requires nontraditional participation or cost-share; most commercial startups qualify as nontraditional.
  • award in ~60–90 days (recent average closer to ~120 days)

How to apply: You don't apply for an OT directly — you win a CSO and DIU negotiates the OT prototype agreement with you.

Production

Production Other Transaction (P-OT) — the follow-on prize

The real payoff. A successful prototype OT can transition, without re-competing, into a sole-source production OT or FAR contract — often worth far more than the prototype. DIU reports ~51% of completed prototypes transition to production.

  • $10M–$100M+ (e.g. Anduril's ~$99M counter-UAS P-OT) · Non-dilutive
  • You must have successfully completed a prototype OT and met its stated success metrics.
  • after prototype completion

How to apply: Deliver the prototype and satisfy the transition criteria written into your OT; the sponsoring component then negotiates production directly.

OTA

National Security Innovation Capital (NSIC)

DIU-affiliated program that funds dual-use HARDWARE startups facing a shortfall of trusted private capital. Hardware and materials only — no software-only plays.

  • ~$500K–$3M (avg ~$1.8M) · Non-dilutive
  • Early-stage (angel/seed, pre-Series-A) hardware startups at TRL 3 or higher with a dual-use product.
  • rolling (Commercial Acceleration Opportunity is continuously open)

How to apply: Submit a pitch deck at any time under the open Commercial Acceleration Opportunity; selected teams pitch, then negotiate a prototype OT (~12–18 month period of performance).

OTA

Replicator / Replicator-2 lane (JIATF-401)

The DoD's fast-fielding initiative. Replicator-2 focuses on counter-small-UAS. DIU CSOs and prize challenges are the entry ramps; JIATF-401 made its first R2 purchase (Fortem DroneHunter F700 systems) in January 2026.

  • varies; production-scale intent · Non-dilutive
  • Counter-UAS and related autonomous-systems providers responding to R2-aligned solicitations.
  • tied to specific R2 solicitations and challenges

How to apply: Respond to Replicator-2 CSOs and JIATF-401 counter-UAS solicitations posted through DIU, or enter an associated prize challenge.

Prize

DIU Prize Challenges

Non-dilutive cash prizes for demonstrating a capability against a defined problem — a low-friction on-ramp that often feeds directly into CSO awards. Example: the C-sUAS Low-Cost Sensing Challenge (MatrixSpace won the ~$500K top prize; three runners-up took ~$100K each).

  • ~$100K–$500K per challenge · Non-dilutive
  • Open to companies with a demonstrable solution; rules vary per challenge.
  • episodic (per challenge)

How to apply: Register and submit against the specific challenge posted on DIU's submit-a-solution portal.

Grant

DIU OnRamp Hubs

Regional physical hubs (Arizona, Hawaii, Wichita KS, Dayton OH, Renton WA; Kentucky, Minnesota, and Montana planned) offering mentoring, events, and warm introductions into the DoD marketplace for companies outside the coastal tech centers.

  • programming (not direct capital) · Non-dilutive
  • Regional startups and dual-use companies building toward DoD engagement.
  • ongoing events and cohorts

How to apply: Connect with your nearest OnRamp Hub for events, office hours, and referrals into DIU solicitations.

Grant

NSIN Vector & Propel (under DIU)

The National Security Innovation Network was absorbed into DIU in fall 2024, but its dual-use programming continues: Vector (a startup accelerator that pairs teams with OnRamp Hubs) and Propel (commercial-accelerator collaborations). Propel-linked ventures have historically drawn ~$100M+ in DoD funding and ~$250M in private investment.

  • programming + follow-on funding pathways · Non-dilutive
  • Early-stage dual-use startups and founders.
  • annual cohorts

How to apply: Apply to open Vector or Propel cohorts announced through NSIN/DIU channels.

Contract

Blue UAS onboarding pathway

DIU's vetting and cleared-list process for trusted small drones and components (the Blue UAS Cleared List). Getting on the list makes it dramatically easier for DoD buyers to procure your platform.

  • no direct award (market-access value) · Non-dilutive
  • sUAS and component makers meeting cybersecurity and NDAA supply-chain requirements.
  • periodic onboarding tranches

How to apply: Respond to Blue UAS onboarding solicitations and pass the technical/security vetting.

The lifecycle

How funding flows — and where simulation fits

01

Solution Brief

$0 (screening) · ~5 pages / ~15 slides

Prove your commercial tech maps to a specific Area of Interest and can be adapted for the mission.

A single simulation figure — a stress plot, a CFD contour, an antenna pattern — makes a brief read like a mature engineering team, not a pitch.

02

Pitch

$0 (down-select) · ~30-minute session

Show the DIU team and the sponsoring component that you understand the operational problem and can deliver on the timeline.

Simulation-backed performance predictions let you answer 'will it survive / fly / radiate?' questions on the spot instead of promising to test later.

03

Proposal & Prototype OT Award

prototype scope (often ~$500K–$10M) · award in ~60–120 days

Negotiate scope, success metrics, and IP, then sign the Other Transaction prototype agreement.

Simulation lets you commit to aggressive prototype milestones with confidence because the hard physics is already modeled.

04

Prototype Execution

per the OT · months to ~2 years

Build, test, and demonstrate the prototype against the agreed success criteria.

Digital iteration replaces destroyed test articles — you burn through design variants virtually and only build the ones the model says will pass.

05

Production OT / Transition

$10M–$100M+ · sole-source, no re-compete

Convert a successful prototype into a production OT or program of record.

At scale, simulation supports qualification, reliability, and manufacturing sign-off so you can produce at volume without surprise field failures.

Chasing one of these?

The technology behind most of these awards has to be proven with physics. We can arrange an Ansys evaluation license with live engineering support so you can build the feasibility evidence reviewers and investors want to see — at no cost while you're pre-funding.

Chasing one program often means you qualify for others you haven't heard of. These sister guides cover more of the U.S. non-dilutive landscape — same honest, no-nonsense approach. Not sure which fits what you're building? Ask us — we'll point you at the right doors, even the ones that aren't ours.
