StartTech Ventures
StartTech Ventures operates from San Francisco and Athens, founded by Dimitris Tsingos to co-create B2B SaaS companies for North American commercial strategies. The firm publicly describes itself as "venture builders" who act as angel investors, providing pre-seed or seed financing alone or through co-investors including the Hellenic Business Angel Network. Strategy centers on enterprise-software startups from seed through scale-up. The firm's portfolio page groups holdings into three tracks: a Venture Building Portfolio (including DreamClass, Gracely, and Tourmie), a Seed Investments Portfolio (including Mindstοne, Elorus, and Nomi Health), and a HeBAN Portfolio tied to angel network activity. Portfolio tagging indicates a focus on active ventures and graduated companies, with exited positions and dropped holdings also disclosed. Published success cases AbZorba Games, Epignosis learning technologies, and Yodeck each reached scale without external venture funding, instead relying on customer revenue and tight budgets. Team size is not publicly disclosed; the website lists 18 professionals across venture building and operations roles, with an R&D center at Lykourgou 1 in Athens. The Athens office houses product design, web development, performance marketing, and systems administration, supporting the firm's direct co-creation model. Insight Partners' Managing Director Nikitas Koutoupes has publicly noted openness to future collaboration with the firm. StartTech Ventures is structurally unusual among early-stage investors: it functions as a co-founder rather than a passive LP-backed fund. Portfolio companies access a shared operational team and physical workspace, effectively receiving build support alongside capital. This hybrid venture builder–angel investor architecture replaces widespread syndication with concentrated, hands-on company creation.

Frequently asked questions
Who runs investment decisions at StartTech Ventures?
Founder and President Dimitris Tsingos leads strategy, with Managing Director Iro Tsakiri and Head of Operations Katerina Kastriti overseeing day-to-day portfolio support from the Athens R&D center. The firm publicly positions itself as a co-founder rather than a passive investor, so decisions integrate directly with the founder team around each venture.
How does StartTech Ventures source deals?
The firm builds most ventures internally, often originating concepts and assembling founding teams rather than sourcing external rounds. It also co-invests alongside the Hellenic Business Angel Network for pre-seed and seed-stage B2B SaaS startups with North American commercial ambitions.
Does StartTech Ventures raise external funds or is it a single-family-backed vehicle?
StartTech Ventures has not publicly disclosed its capital source. The firm does not reference limited partners or fund structures on its site, and its success-case narrative emphasizes building companies without external venture rounds, relying on customer revenues and lean operations.
What investment stages does StartTech Ventures typically target?
Pre-seed and seed financing, alone or with angel co-investors, for early-stage startups. The firm stays engaged through the scale-up phase, supported by its venture building team, and has demonstrated exits at scale with companies such as Epignosis.
Which sectors does StartTech Ventures explicitly avoid?
The firm has not published a formal exclusion list. Its disclosed record is entirely in B2B SaaS, with portfolio examples such as Epignosis learning technologies, Yodeck digital signage, AbZorba social casino games, and Elorus invoicing — no hardware, deep tech, or consumer social companies appear in portfolio listings.
What is StartTech Ventures' posture on co-investments alongside external GPs?
The firm co-invests with angel networks, most prominently the Hellenic Business Angel Network, and maintains relationships with later-stage capital such as Insight Partners. Nikitas Koutoupes of Insight has publicly acknowledged the quality of StartTech's portfolio after investing in Epignosis.
Why does StartTech Ventures have an office in Athens?
The Athens office functions as the firm's R&D and venture building hub, housing product designers, developers, performance marketers, and operations staff. This structure allows portfolio companies to access a shared build team while pursuing North American go-to-market strategies from the San Francisco headquarters.
