Investor Profile: SineWave Ventures — Thesis, Cheque Size & How to Apply

SineWave Ventures is a venture capital firm bridging Silicon Valley and Washington, D.C., investing in early-stage enterprise technology companies whose products serve both commercial customers and the public sector. Founded by Yanev Suissa, SineWave is ranked a top 5 percentile fund per Cambridge Associates and says it has returned limited partners seven times what they invested. For founders hunting SineWave Ventures funding, here is the thesis, fund sizes, portfolio and pitch route.

Thesis & focus

SineWave runs a deliberately concentrated portfolio — a small number of high-conviction bets — guided by four pillars: Thesis-Driven Investing, Strategic Network-Based Execution, Proven Performance and a Concentrated Portfolio. Its edge is dual-use technology: software that solves challenges common to Fortune 500 companies and government enterprises alike. The team works closely with startups to access federal contracts and navigate commercial business opportunities, a positioning that becomes especially valuable when private markets cool and public-sector technology spending keeps growing. Its technology lenses are Data, Human Applications, Systems and machine-level complexities — abstracting away the friction in analytics, data processing and distributed data environments.

Sectors & stages

SineWave focuses on cybersecurity, artificial intelligence, cloud computing, data science and enterprise technology — explicitly including dual-use companies that can sell to both the commercial and public sectors. It invests at the early stages, and its focus geographies are in North America.

Fund size & cheque size

In July 2023, SineWave closed its $160.3 million Fund III, which was oversubscribed by 30%. The firm now has more than $300 million committed across its diversified funds. It does not publish standard cheque sizes.

SineWave Ventures funding: notable portfolio

SineWave's portfolio is concentrated in enterprise and security infrastructure. Companies shown on the firm's own site include Corsha, CoreStoryAI, Granica, DataHub, Thoras, RunSafe Security, Metronome, Mage, Invary (runtime integrity), Dymium, Arize (ML observability), Anjuna (confidential computing), Stacklet, DBOS and Evry.

Partners & team

The firm was founded by Yanev Suissa, who describes the team's approach as "strict financial discipline" combined with the ability to "spot real enterprise solutions" across commercial and public-sector markets. The partnership includes operators with deep federal-market experience — veterans of government acquisitions and national-security institutions — which underpins the firm's Washington bridge-building model.

How to apply for funding

SineWave does not publish an open application portal or a general pitch email. The realistic route is a warm introduction through its portfolio network, cybersecurity and data-infrastructure community, or advisors with federal-market credibility. Founders with dual-use potential — technology that a Fortune 500 CIO and a government agency would both buy — should lead with that framing.
