About the company
Vivalon, doing business as Whistlestop, is a San Rafael, California–based non-profit organization that operates as a federal grant sub-recipient, not as a prime contractor. The vendor has received three federal grant sub-awards totaling $325 thousand since 2021, all designated as operating assistance.
Vivalon's federal footprint is narrow and grant-focused. All three awards are sub-awards rather than prime grants or contracts. The vendor received one sub-award in September 2021 and two additional sub-awards in 2025 (June and October), both carrying operating-assistance designations. The source does not name the prime grant recipients, grantor agencies, federal grant programs, CFDA numbers, or the specific work performed under these sub-awards. Activity has been episodic — one award across a four-year gap, then two awards within four months in 2025 — with combined federal obligation of $325 thousand across the period.
The vendor does not hold a seat on any federal contract vehicles, IDIQs, GWACs, or BPAs. No contracting federal agency relationship is documented in the source. No prime-contractor awards or subcontractor relationships on federal contracts are present in the portfolio.
