$340MSeries C raised by Tempus AI

Tempus closes $340M as genomic-guided oncology hits the reimbursement inflection point.

Three payers moved to cover AI-assisted tumor profiling within 60 days of the Tempus round closing — a pattern that mirrors the 2021 cardiac AI wave. The next 90 days will determine if this becomes policy or noise.

510(k)FDA pathway — 23 new clearances this month

The FDA cleared 23 AI/ML devices in January — a 41% spike over the trailing 6-month average.

Eleven of the 23 are radiology-adjacent, but the quieter story is four wound-care devices that cleared via De Novo — signaling a new FDA appetite for dermatology AI outside the hospital setting.

94.7%sensitivity — diabetic retinopathy detection

Google DeepMind's retinal scan model outperforms ophthalmologist consensus in low-resource clinic trial.

The 8-country trial is the largest prospective validation of any ophthalmic AI to date. Critically, sensitivity held above 93% even on commodity smartphone cameras — the hardware barrier just dropped.

6wearable cardiac monitors — FDA cleared Q1 2026

Six continuous cardiac monitors cleared in Q1 — three are direct-to-consumer, breaking the prescription-only barrier.

The DTC clearances are narrow (AFib detection only) but the precedent is significant. Expect insurers to begin covering remote cardiac monitoring for non-diagnosed populations within 18 months.

−37%hospital readmission rate — AI discharge planning trial

Mass General's AI-assisted discharge protocol cut 30-day readmissions by 37% in a 2,400-patient RCT.

The model uses social determinants of health data alongside clinical vitals — a combination regulators have historically flagged for bias. The IRB methodology here is worth studying before you pitch similar tools.

$1.2Btotal healthtech VC deployed — January 2026

January 2026 healthtech VC: $1.2B deployed across 34 deals, with mental health tech absorbing 28% of capital.

Mental health's share of healthtech VC has doubled since 2023, driven by employer-mandate tailwinds and the first wave of parity law enforcement actions. The category is crowded but the acquirers are circling.

CMS-2025Final rule — remote monitoring reimbursement

The CMS final rule on remote patient monitoring changes the economics of 14 device categories overnight.

The reimbursement rate for RPM setup codes increased 22% while continuous monitoring codes were consolidated — a net positive for platforms with recurring revenue models but a cliff edge for one-time hardware plays.

3 of 10top hospital systems building proprietary AI vs. buying

The build-vs-buy inflection: three of the top ten US health systems have quietly hired AI teams to replicate vendor tools.

Epic's API strategy made this possible. The implication for vendors: your moat is no longer the model — it's the workflow integration, the regulatory clearance, and the liability coverage.

Phase III4 AI-powered therapeutics entering Phase III trials

Four AI-designed drug candidates entered Phase III simultaneously — the first cohort to reach this milestone.

Two are small molecule oncology compounds, one is a protein therapeutic for rare disease, and one is a repurposed generic. The repurposed compound has the most interesting IP structure — worth a deeper look before the data readout.

↓18%digital health deal count vs. 2024 peak

Deal count is down 18% from 2024's peak, but average round size is up 34% — the healthtech funding market is concentrating, not contracting.

Seed-stage activity has collapsed while growth-stage rounds are larger than ever. The implication: the next generation of healthtech winners may already be funded, and the window for new entrants is narrowing in most categories.
