Supplemental Funding Opportuniy - Phase IB

Skip to Content

In Phase I, the primary Supplemental Funding Opportunity is Phase IB. It bridges the gap between Phase I and possible Phase II funding and helps accelerate that project to the commercialization stage by matching 50% of third party investment (minimum third party investment: $30,000) to extend the R&D effort beyond the current grant to meet technical requirements of the third party investor(s).

Due Date: October 15 or April 15 (whichever date falls during the Phase I period of performance). Phase IB proposals MUST be submitted using FastLane (

Max Funding: 20% of the Phase I award (generally a maximum of $30,000 of NSF funding based on $60,000 of outside investment)

Detailed Dear Colleague Letter: More information


Proposals must be submitted according to the instructions for submitting supplemental funding requests found at the following URL:

Proposals must address two issues:

  • The research activities that will be funded by the NSF to strengthen the project's scientific and engineering feasibility;
  • The business development and marketing activities that will be supported by the outside funds.

The majority of the Phase IB proposal details should be included in the "Summary of Proposed Work" module and shall not exceed 15 pages (a length of 4-6 pages is highly recommended). The additional work proposed should be an expansion of the technical work being performed in the Phase I project and must fall within the scope of the present Phase I project and its logical path to commercialization.

Preparing the proposal using the FastLane system:

  1. Go to the FastLane Home Page (
  2. Select from the left hand-side of the page the "Proposals, Awards and Status" link

Summary of Proposed Work

New R&D Activities. A length of 4 to 6 pages is highly recommended for this section. This section should contain three parts:

  1. A discussion of the "New" R&D activities which the additional NSF funding will support, including technical objectives and work plan;
  2. A brief description of the nature of the fully executed third-party funding commitment, and a brief discussion of how the third-party funding will be used to accelerate and/or expand commercialization; and
  3. The Phase IB data table, as explained in the Dear Colleague Letter.
  4. If the information provided in the Phase I proposal is still true and accurate, please include the following statement: "I affirm that the certifications ( submitted with the Phase I proposal are still true and accurate." If any of this information has changed, please inform your Program Director and include a new SBIR/STTR Funding Agreement Certification as a supplementary document.

Justification for Supplement

Third-Party Investment Documents. Upload all relevant documentation from the fully-executed third-party investment. This includes evidence of a legal commitment of funds (signed contracts, investment documents, purchase orders, license agreements, etc.) and, where available, evidence of receipt of funds (bank statements, wire transfer notices, etc.).

Revised Expiration Date

New Phase I expiration date. Add 6 months to your current expiration date (found in your Phase I award letter).

Budgets (including Justification)

Phase IB budget. Prepare new budget for the Phase IB activities (only include the requested NSF funding in the budget).

  1. Provide complete line item justification for ALL budget items.
  2. The budgeted rates MUST not exceed the rates used in the Phase I budget. Furthermore, the budget justification must include a statement that all budgeted rates do not exceed the rates awarded under the Phase I grant. Budgeted rates include salaries, indirect costs, fringe benefits, overhead, G&A, unit cost rates, etc. In the Budget Justification, include the following statement to certify this: "The rates listed in the main Phase I award budget remain unchanged in the supplemental funding budget".
  3. All items listed under materials and supplies or “other” should be accompanied by price quotes and/or invoices, if the extended amount is over $5,000. If the prices come from catalogs then identify the catalog. In the Phase IB, no capital equipment purchases are allowed.
  4. Trips should be broken down and conferences should be identified, along with the name of the person to present research results. Only the person presenting results will be able to charge to this award.
  5. The Phase IB budget must also adhere to the NSF SBIR requirement that the PI must be primarily employed by the company, and the PI must commit a minimum of 1 calendar-month of effort to the project.
  6. The budget must also allocate at least 66% of all funds to the small business, as was required in Phase I.
