Element 8 Angels
T.A. McCann founded Element 8 Angels in 2006 after a career building and selling technology companies in Seattle, most notably as a founder of Senosis, acquired by Google, and as a key early engineer at Microsoft's Exchange group. The firm represents a reinvestment of McCann's own technology wealth alongside a vetted group of co-investors — primarily current and former senior leaders from Microsoft, Amazon, and local exits — who share the same appetite for high-conviction, early-stage technology risk. Element 8 writes initial checks between $100,000 and $500,000, focusing on pre-seed and seed-stage software and hardware-enabled startups. The portfolio spans enterprise SaaS, AI and machine learning platforms, digital health diagnostics, and climate-related mobility systems. Known portfolio companies include the battery analytics firm Accure, digital health startup Wally, and the corporate energy procurement platform LevelTen Energy. The group favors founders with deep technical backgrounds and a path to enterprise sales velocity, often co-investing alongside established Pacific Northwest seed funds like Voyager Capital and PSL Ventures. Investment geography is concentrated in the Pacific Northwest but extends selectively into the broader West Coast and British Columbia. The group operates with a lean structure centered on McCann as Managing Director, supported by a rotating cast of angel members who bring deal flow and domain diligence. Element 8 does not disclose aggregate assets under management but has publicly reported more than 65 portfolio companies across 11 years of continuous investment, signaling consistent capital deployment. In addition to Element 8, McCann serves as a Venture Partner at Pioneer Square Labs, the Seattle venture studio, creating adjacency between studio-originated seed opportunities and the Element 8 checkbook. In January 2024, Element 8 participated in a $4.1 million seed round for Accure alongside Blue Bear Capital, extending the firm's sustained commitment to energy transition infrastructure. Element 8's structural signature is its blend of single-family capital with a curated syndicate of operator-angels — a model that retains the speed and personal conviction of a family office while scaling diligence and network reach through a tightly controlled member base. Unlike open angel groups that vote on deals, Element 8 is ultimately McCann's vehicle, meaning investment decisions are concentrated and conflicts are minimal. That architecture, combined with his dual role at a venture studio, gives Element 8 early visibility into talent and company formation that most standalone angel groups cannot replicate.

Frequently asked questions
Who runs investment decisions at Element 8 Angels?
T.A. McCann operates as Managing Director and makes the final call on every investment. His background includes engineering leadership roles at Microsoft and founding Senosis, a health-tech startup acquired by Google. The broader angel membership contributes deal flow and diligence but does not vote on allocations.
How does Element 8 source proprietary deal flow?
Deal flow comes from the combined professional networks of McCann and the angel members — heavily concentrated in former Microsoft, Amazon, and Seattle tech alumni channels. McCann's concurrent role as Venture Partner at Pioneer Square Labs also funnels studio-originated companies into early consideration. The firm rarely takes inbound cold applications.
Is Element 8 structured as a single family office or an angel network?
It operates as a hybrid. The capital is majority McCann family money, deployed alongside a curated, invitation-only group of co-investors who write personal checks. Unlike a typical angel group with membership fees and broad voting, Element 8 functions as a single checkbook with an extended network, giving McCann concentrated decision-making authority.
What investment stages does Element 8 Angels target?
Element 8 focuses on pre-seed and seed-stage rounds, typically writing initial checks between $100,000 and $500,000. The firm occasionally follows on in bridge or Series A rounds but does not lead later-stage financings. Its preference is for founder-led companies with a working product and early customer validation.
Does Element 8 participate in fund commitments or only direct deals?
Element 8 invests primarily through direct equity in operating companies. There is no public record of the group making limited partner commitments into venture capital funds. The model is direct angel investing, aligned with McCann's operator ethos.
Where does the underlying wealth come from?
The core capital originates from T.A. McCann's career as a technology founder and early employee. His liquidity events include the sale of Senosis to Google and his tenure as a senior engineer at Microsoft during its formative growth period. Co-investors are similarly situated operators who built wealth at large Pacific Northwest technology employers or their own exits.
How is Element 8 related to Pioneer Square Labs?
McCann serves as a Venture Partner at Pioneer Square Labs, a Seattle-based venture studio that ideates and launches startup companies. Element 8 and the studio operate as separate entities, but the relationship creates natural early access to studio-formed companies and their founding teams, giving Element 8 a sourcing advantage in the Seattle market (per GeekWire, 2023).
