NSF X-Labs Initiative - From Sequence to Function
National Science Foundation
AI summaryStep 1 of 2: Written Proposals are due February 8, 2027, 5:00 PM Eastern; only teams the National Science Foundation (NSF) invites after reviewing them may send the second-step Oral Proposal Package and give an oral presentation. NSF's Directorate for Technology, Innovation and Partnerships (TIP) wants full-time bioengineering research teams ("X-Labs") to build platform technologies that link protein sequence to biological function. This is an Other Transaction (OT) agreement, a research agreement that is not a standard FAR-based contract, paid by milestones, with up to $1,500,000 for a Phase 0 of about 9 months and up to $50,000,000 per year for Phase 1.

Who can bid (5)
- Lead organization must be a domestic responsible entity; NSF signs the OT with one lead organization only (it may be made of several entities and may subcontract to partners)
- Lead organization must be registered in the System for Award Management (SAM) before submitting; SAM registration can take up to 10 days, and a missing UEI may get the proposal removed
- Research security: U.S. proscribed parties (federal restricted-party lists), foreign entities of concern, and people in a malign foreign talent recruitment program cannot take part. Citizens of North Korea, China, Russia or Iran cannot be Senior/Key Personnel

- Team expected to operate with substantial independence in decisions, staffing, funding and partnerships; NSF applies an autonomy factor assessment and expects a governance structure plan for Phase 1
- Signed conflict of interest statement (Attachment B) disclosing any organizational conflicts of interest, covering the lead organization, employees and proposed subcontractors or consultants

Things to watch (10)
From the version posted Oct 14, 2026.
- Serious: SAM.gov and the solicitation disagree on the set-aside. SAM.gov lists no set-aside, but the solicitation the AI read says a set-aside for small businesses. Ask the contracting officer which applies before you bid.
- Serious: Two-step process: only invited teams reach the oral stage. Written Proposals are due February 8, 2027 (Topic Announcement). NSF then invites only the most highly qualified teams to send an Oral Proposal Package and give an oral presentation, with the package due about 5 business days before the presentation and key personnel disclosures about 48 hours after the invitation (Program solicitation, September 16 amendment). A team not invited is out of the competition.
- Serious: Not a typical small business contract: research teams with independence from their host organization. The program is for full-time R&D teams with broad control of funding, hiring and research direction, and no small business set-aside applies. A small firm without a research team and a governance plan is unlikely to be competitive.

- Serious: Research security restrictions on organizations and key personnel. Restricted parties and people tied to certain countries cannot be Senior/Key Personnel, and annual compliance certifications may be required.
- Serious: SAM registration and UEI needed before submitting. Registration can take up to 10 days, and a missing UEI may get the proposal removed. Check a SAM.gov registration.
- Worth checking: Strict 8-page limit and file format. References count inside the 8 pages, files must be 1.5 MB or less, and non-conforming proposals may be removed.
- Worth checking: Limit on number of proposals per organization and per person. An organization may lead at most two Written Proposals for this topic, and key personnel can appear on only one, so teaming choices matter.
- Worth checking: Biosafety and gain-of-function assessment expected. Teams on this topic should address biosafety and biosecurity, including dangerous gain-of-function and a mitigation plan.
- Minor: Many out-of-scope topics. Narrow, incremental or already well-funded technologies and standalone predictive models without new experimental data are not in scope.
- Minor: Phase 0 length differs between documents. The Topic Announcement says 9 months with Go/No Go after 7 months; the program solicitation says approximately 9 to 12 months with Go/No Go in the last quarter. The topic-specific figure is likely the one that applies, but confirm with NSF.

Full summary
What they want
- Written Proposal for an NSF X-Lab team that defines a Mission: a novel platform technology to link protein sequence and structure to function
- Platform technologies that make protein or whole-genome function predictable or controllable (protein design and synthesis, genome assembly, synthetic cells, or experimental discovery and validation)
- A technology landscape analysis comparing today's state of the art with the team's goal
- Measurable outcomes over a 5- to 7-year timescale
- Two to three high-utility application domains for the platform
- A biosafety and biosecurity approach, including an assessment of dangerous gain-of-function and a plan to reduce unintended consequences
- A team structure with the independence (autonomy) NSF describes for X-Labs, and complementary leadership, technical and entrepreneurial expertise
- A signed conflict of interest statement (Attachment B)
- Contract type
- Other Transaction (OT) contract under 42 U.S.C. 19116: neither a FAR-based procurement contract nor a grant; base OT award with milestone-based payments (milestones finalized in negotiation); one or more awards
- Period of performance
- Phase 0: about 9 months in the topic announcement (9 to 12 months in the program solicitation), with a Phase 1 Go/No Go selection starting after 7 months. Phase 1: about 24 to 36 months. Phase 2: variable length, for high-performing teams after later Go/No Go selections

- Proposals that do not meet the format specifications may be removed from consideration
After award, you must have
- Senior/Key Personnel and core leadership must be dedicated full-time to the team by the beginning of Phase 1, unless NSF approves otherwise From NSF-XLabsOTASO-September16Amendment.pdf:
…dedicated full-time to the team by the beginning of Phase 1, unless otherwise approved by NSF.
