Flyby's listed site resolved live when we last probed it on Aug 24, 2026, so we mark it verified alive. It has fewer than two observed signal families, so no Pulse Index is composed — the evidence strip shows what is and isn’t present. Observed footprint: 2 functional tags. It sits on the competitive-alternatives graph with 3 linked rivals, so the comparable set below leans on curated edges.

No disclosed funding in our sources. Funding data covers only ~1% of the corpus (462 rounds across 79K products), so absence here is unknown, not zero— we don't estimate a number we can't source.
