Among the 13 AI-focused entries shown, the largest disclosed round is Aisles’ $30M (2024-05-18), which sits well above the rest of the disclosed amounts: multiple companies cluster at $3M–$6M (First Ascent Biomedical $6M on 2025-01-13; Sightglass $3M on 2024-12-05; Shelpful $3M on 2023-12-15), with CleanHaus at $250K (2026-01-12) and KinoTek at $600K (2021-02-17) further below. The disclosed amounts therefore show a clear upper tier (only Aisles at $30M) versus a mid-range where most other disclosed rounds land.
Geographically, Portland dominates the list: 10 of 13 companies are based in Portland (e.g., PlumBuddy on 2026-04-07; Regulate on 2025-07-17; First Ascent Biomedical on 2025-01-13), with the remaining three in Portland, Maine (RxAnte, 2026-01-12; KinoTek, 2021-02-17) and Portland, Maine (RxAnte and KinoTek) plus Portland, Maine for those two. Temporally, the newest edge is 2026-04-07 (PlumBuddy), while the oldest shown date is 2021-02-17 (KinoTek). Stage/disclosure is skewed: 7 of 13 entries have undisclosed amounts, and only three disclosed Seed rounds appear ($250K, $6M, $3M).

Frequently asked
What’s the largest disclosed AI round in this Portland-focused list, and how does it compare to other disclosed amounts?
Aisles’ $30M (2024-05-18) is the only disclosed round above $20M in the 13-row view. The next tier is much lower, with First Ascent Biomedical at $6M (2025-01-13) and multiple $3M rounds (Sightglass on 2024-12-05 and Shelpful on 2023-12-15).
Do the rounds cluster in time, or are they spread evenly across years?
Most disclosed activity is concentrated in a multi-quarter window around 2024–2025: Sightglass ($3M on 2024-12-05), Aisles ($30M on 2024-05-18), and First Ascent Biomedical ($6M on 2025-01-13) all fall within that span. The dates also reach back to 2021 (KinoTek $600K on 2021-02-17), but the most recent edge is 2026-04-07 (PlumBuddy, undisclosed).
Which cities are over-represented across these 13 AI startups?
Portland appears in 10 of 13 rows, including Portland, Oregon for multiple companies such as Porter Labs (2026-02-12, undisclosed) and Regulate (2025-07-17, undisclosed). The remaining entries are tied to Portland, Maine (RxAnte on 2026-01-12, undisclosed; KinoTek on 2021-02-17, $600K).
How much of the list is undisclosed vs disclosed, and what does that mean for interpreting the funding range?
7 of 13 entries list “undisclosed” amounts, which limits how much can be compared across the full set. Among disclosed rows, the range includes CleanHaus at $250K (2026-01-12) through KinoTek at $600K (2021-02-17) and up to Aisles at $30M (2024-05-18).
Which stages show up most often among the entries shown?
Seed is the most common labeled stage among the 13 rows, appearing across several companies including CleanHaus ($250K on 2026-01-12), Regulate (2025-07-17, undisclosed), First Ascent Biomedical ($6M on 2025-01-13), Sightglass ($3M on 2024-12-05 is also Seed), and Shelpful ($3M on 2023-12-15). Pre-Seed appears for PlumBuddy (2026-04-07 is Seed vs Pre-Seed for Porter Labs 2026-02-12 and Stitch Studio 2025-04-01), while later-stage labels include UMU (Series C, 2021-11-01, undisclosed) and Aisles (Series A, $30M on 2024-05-18).
Are there outliers worth focusing on beyond the single largest round?
Yes. CleanHaus’ $250K (2026-01-12) and KinoTek’s $600K (2021-02-17) are notably low within the disclosed subset, while Aisles’ $30M (2024-05-18) is the clear high outlier compared with $6M (First Ascent Biomedical, 2025-01-13) and $3M rounds (Sightglass, 2024-12-05; Shelpful, 2023-12-15).
