When it comes to discovering which tech startups are beginning to consider IPOs, one major signal is when they hire new chief financial officers that have public market experience. It's not foolproof, but directionally decent. With that in mind, two new hires of note:

• J.D. Fay is the new CFO at Matterport, a Silicon Valley-based 3D reality capture and distribution platform. He's helped take both NeoPhotonics and @Road public.
• Pete Perrone is the new CFO at AtScale, a business intelligence platform that today announced $25 million in new VC funding. He is a former Goldman Sachs banker who also served as CFO Limelight Networks.
