A stealthy Seattle startup has raised seed funding from Silicon Valley venture capital firm Greylock and Bellevue, Wash.-based Trilogy.

Falkon AI has “discovered a revolutionary way to combine machine learning and human intuition to empower professionals to define, understand and improve metrics that really matter,” according to its website. The company describes its technology as a “new system of intelligence” that works with “massive customer datasets,” according to job postings.

Mona Akmal, a 12-year Microsoft veteran who was most recently head of product at Seattle startup Amperity, is CEO and co-founder of Falkon AI. Akmal also held executive engineering roles at Code.org and Zulily.

The other co-founders are Aakash Kambuj, another former Microsoft engineering leader who previously spent six years at Dropbox, where he led the search and retrieval engineering team out of the company’s Seattle office before departing in October. Josh Zana, a veteran of Dropbox, Amazon, and Microsoft, rounds out the founding team.

Falkon is currently hiring for eight open roles. Akmal, a former GeekWire Geek of the Week, declined to provide further details about the company when contacted by GeekWire.

The CEO recently spoke at a Seattle Startup Week event, sharing tips about launching a company. Akmal said she loved her team at Amperity, a customer data platform that just raised $50 million, but she also had “absolute clarity” about venturing out as a startup founder.

Greylock is one of the Valley’s most prominent VC firms, with more than $3.5 billion under management and 130-plus profitable M&A’s since 1965. Its past investments include LinkedIn, Airbnb, Facebook, Instagram, Nextdoor, Okta, Workday, and others. LinkedIn co-founder Reid Hoffman is a partner at the firm.

Greylock is an investor in Seattle-based unicorn Convoy and online learning platform CreativeLive; it also recently led a Series A round for Chronosphere, a cloud startup founded by former Uber and Microsoft engineers with an office in Seattle.

Trilogy is an active Seattle-area investor, with recent investments in startups including Spiral; Fresh Chalk; Give InKind; Adaptilab; and others.
