Frequently asked
What’s the largest disclosed round in this Mercer Island slice, and how far above the rest is it?
AltPep’s $53M Series B (2023-06-22) is the only disclosed amount above $50M. The next-largest disclosed amounts are $16M (Xplore, 2022-02-24) and $10M (ModusBox, 2022-09-13), with Nowadays at $2M (2024-12-06).
How concentrated are the rounds in time across these 6 rows?
There’s a December 2024 cluster: Nowadays closed $2M on 2024-12-06 and WPAS closed on 2024-12-19, with WPAS’s amount undisclosed. Otherwise, the disclosed rounds spread across 2022 (Xplore 2022-02-24, ModusBox 2022-09-13) and 2023 (AltPep 2023-06-22), spanning 2022-02-24 to 2025-10-20 overall.
Which entries have undisclosed amounts, and do they cluster around a particular period?
Two of the six rows are undisclosed: PortX (2025-10-20, Series B) and WPAS (2024-12-19, Series Unknown). With one undisclosed entry in late 2024 and the other in late 2025, they don’t concentrate in a single tight window beyond the December 2024 timing for WPAS.
Is any sector over-represented in this city list?
Data and analytics is the only sector repeated in the rows shown, appearing twice: PortX (Data and Analytics, 2025-10-20, undisclosed) and ModusBox (Data and Analytics, 2022-09-13, $10M). All other sectors shown—biotechnology (AltPep), technology (Nowadays), financial services (WPAS), and Other (Xplore)—appear once each.
How does the stage mix look when focusing on disclosed amounts vs. missing amounts?
Among the 4 disclosed-amount rows, Seed and Series A/B are all present: Nowadays is Seed at $2M (2024-12-06), AltPep is Series B at $53M (2023-06-22), ModusBox is Series A at $10M (2022-09-13), and Xplore is Series A at $16M (2022-02-24). The other 2 rows are undisclosed in amount (PortX Series B in 2025-10-20 and WPAS Series Unknown in 2024-12-19), so stage reporting can’t be fully compared using disclosed dollars alone.
