Full answer
Fundbox is a legitimate fintech lender founded 2013, headquartered in San Francisco. Backed by tier-1 venture capital: Khosla Ventures, GV (Google Ventures), General Catalyst. Tech-platform partner with Coastal Community Bank for LOC funding.
Track record: $3B+ funded to 100,000+ small businesses. Earlier-stage focus than Bluevine — willing to fund newer businesses with shorter operating histories.
Products: Business LOC ($1K-$150K, weekly fee structure 4-9% over 12/24 weeks, equating to ~30-60% effective APR). Discontinued separate invoice factoring product in 2021 — now bundled into LOC underwriting.
Acceptance: 6+ months TIB, 600+ credit, $8K+/mo revenue. Lower bar than Bluevine (12+ months, 625+, $10K+) — Fundbox catches newer businesses.
Where to be careful: weekly fee structure can look small but compounds fast for short-term draws. A $10K draw repaid in 12 weeks at 5% weekly fee = $500/week × 12 = $6K total payback. That's 60% effective APR. Verify the all-in cost before drawing.
