Sources: Ultrasound wireless charging firm uBeam looking to raise about $50M or more in Series B potentially valuing the company at $500M+
Context & Ripple Effects
TechCrunch's report on uBeam seeking roughly $50M at a $500M+ valuation landed mid-arc for the ultrasound wireless charging company: its marquee backers — a16z, Founders Fund, Marissa Mayer — were already public knowledge, and by December of that year the firm was still filling its war chest, closing just $2.6M of a $4.7M goal on crowdfunding platform OurCrowd its OurCrowd round, a gap that frames how hard the Series B terms would be to defend.
The raise also sits inside a broader capital wave around ultrasound as a technology platform rather than one application: Ultrahaptics pulled in a $23M Series B for touchless haptic interfaces, Butterfly later raised $250M at a $1.25B valuation for clinical-grade ultrasound-on-a-chip imaging, and UltraSense Systems took $20M for gesture sensing through metal, glass, and wood.
First-order effects
- Investors are being asked to underwrite a half-billion-dollar price for uBeam before its charging product ships commercially, making this a test of whether star-studded cap tables (a16z, Founders Fund, Mayer) can carry a hardware physics bet to a premium markup.
- A closed round at those terms immediately becomes the reference valuation every other early ultrasound hardware founder pitches against.
Second-order effects
- Adjacent ultrasound startups — Ultrahaptics in haptics, UltraSense in gesture sensing, Butterfly in medical imaging — compete with uBeam for the same small pool of specialists in transducer design and ultrasonic signal processing, so each premium raise raises their hiring costs.
- Alternative cable-free power approaches, such as chips powered by ambient radio frequencies like Wiliot's $30M Series B, contend for the same 'power without wires' investor thesis, splitting attention between competing physical mechanisms.
Third-order effects
- If the pattern holds, ultrasound matures from a collection of single-purpose bets into a recognized platform layer spanning charging, haptics, imaging, and sensing — with capital concentrating in whichever application demonstrates shipped hardware first.
- uBeam's own trajectory, from a headline-grabbing $500M+ ask to a partially filled $4.7M crowdfunding target, points toward a market where milestone-based funding discipline increasingly overrides vision-stage valuations in deep-tech hardware.
The trend: Ultrasound is consolidating into a multi-application venture category — charging, haptics, imaging, sensing — where funding follows demonstrated hardware milestones rather than flagship valuations alone.
