TipTop Ventures

Aleksander Siddons leads the firm as Founder and Managing Partner and makes the final call on all investment decisions. The firm operates with a lean team structure, meaning Siddons is directly involved in sourcing, diligence, and portfolio support for every company the firm backs. Prior to founding TipTop, Siddons worked in venture and startup operator roles that shaped his thesis around technical founders and concentrated seed investing.

TipTop writes initial checks in the $500,000 to $2 million range, targeting pre-seed and seed rounds where it can secure meaningful ownership. The firm will lead rounds but also co-invests alongside aligned early-stage funds. Its fund size is intentionally constrained to maintain this concentration, rather than scaling into a multi-stage platform.

Enterprise SaaS and infrastructure are the core focus, but the firm has also backed companies in fintech infrastructure and digital health. The common thread is B2B companies with strong technical moats and recurring revenue models. TipTop has not publicly signaled interest in consumer, hardware, or hard-tech sectors.

TipTop co-invests regularly with other seed-stage funds but is not publicly affiliated with a formal syndicate or GP-cohort program. The firm sources independently through founder networks in Austin, San Francisco, and New York, and occasionally through institutional LP referrals.

TipTop operates a standard venture capital fund structure with a management fee and carried interest model. Limited partners include institutional allocators and family offices, though the firm does not publicly name its LP base. The May 2024 announcement of Fund III confirmed continued participation from existing backers and several new institutional relationships.
