STTR Phase II: Technology Transfer Development Grant 2026
Collaborative research between small enterprises and academic institutions generates transformative intellectual property, yet translating those discoveries into commercially viable technologies requires sustained engineering effort and disciplined project execution. Phase II development grants provide the runway necessary for joint teams to refine algorithmic models, conduct durability testing, optimize bill-of-materials costs, and prepare for pilot deployments with early adopter customers seeking measurable performance advantages. Typical Phase II endeavors include building functional prototypes of neural network inference accelerators, validating novel biomaterial formulations through regulatory preclinical pathways, or engineering API integration layers that connect proprietary sensor platforms with enterprise cloud architectures. The university partnership requirement ensures that deep domain expertise in fields such as quantum photonics, synthetic biology, or advanced metallurgy continuously informs product design decisions, while the mid-market partner contributes market intelligence, customer discovery findings, and commercialization strategy that pure academic environments often lack. This collaborative framework also facilitates workforce pipeline development, as graduate research assistants gain hands-on exposure to product lifecycle management, agile sprint methodologies, and customer-centric design thinking disciplines that prepare them for subsequent careers in technology entrepreneurship. Interdisciplinary ventures combining oceanographic instrumentation, bioinformatics sequencing pipelines, and atmospheric particulate monitoring spectrometry exemplify the heterogeneous portfolio benefiting from Phase II collaborative funding mechanisms.
Program Overview
STTR Phase II continues the mid-market-research institution partnership established in Phase I. Awards provide approximately $750,000 over two years for technology development, prototype creation, and commercialization planning.
Partnership Requirements
Research institution must continue performing 30-60% of Phase II work. This ensures ongoing technology transfer and access to academic expertise and facilities.
Joint commercialization planning between partners is required.
Common Questions
STTR Phase II provides up to approximately $1 million over two years for continued research and development based on Phase I results. The mid-market must maintain its partnership with the research institution, though the work allocation can shift compared to Phase I. The mid-market must perform at least 40% of the work, and the research institution at least 30%, with the balance allocated as agreed between partners.
While it is generally expected that the same research institution partner continues from Phase I to Phase II, changes are possible under certain circumstances with agency approval. If the original research partner is unable to continue, the mid-market must identify a qualifying replacement institution and demonstrate that the new partnership can effectively complete the Phase II research objectives. Agency program managers evaluate such changes case by case.
STTR Phase II awards emphasize prototype development and demonstration of commercial viability rather than delivering finished procurement-ready products. Awardees must show measurable technical progress through quarterly milestone reviews while maintaining mandatory research institution collaboration representing at least thirty percent of project effort. Budgets typically span USD 750,000 to USD 1.5 million over twenty-four months.
Effective partnerships establish clearly delineated intellectual property ownership provisions, revenue-sharing frameworks, and publication rights before submission. The collaborating institution must perform substantive technical work rather than serving as a nominal participant, as reviewers scrutinize contribution authenticity. Joint preliminary data generation through pilot studies significantly strengthens proposals by demonstrating established working relationships.
