What PrimeSet does
PrimeSet is a private network organization composed of senior engineers, engineering leaders, and experienced operators in product, sales, and marketing. The group is headquartered in São Paulo, Brazil, and operates with 51-100 members, including operators from Twitter, Facebook, Google, Airbnb, Coinbase, Brex, The New York Times, and Keybase. PrimeSet co-invests alongside top-tier venture capital firms in early-stage startups and provides those portfolio companies with access to its network and technical expertise. Its founder is Babak Hamadani, an early Facebook and Twitter employee who created Twitter's TypeAhead feature.
The organization's primary customers are startup founders in active fundraising and top-tier VC partners. Founders gain access to a curated technical network for guidance during fundraising and growth stages, while VCs benefit from co-investment opportunities and privileged talent access at portfolio companies. PrimeSet also operates a private careers platform that matches senior candidates with non-publicly-advertised roles at startups within its network, with candidate information visible only to the managing partner.
PrimeSet does not develop or sell proprietary technology products. Its business model is structured around equity participation in portfolio companies rather than fee-based services, with go-to-market driven by referrals through its VC partner network. The organization has participated in at least two disclosed seed-stage investments: c/side ($6M, September 2024) and Deductive AI ($7.5M, November 2025), both in deep-tech infrastructure categories.

PrimeSet competitors and assessment
Company assessmentDirect peers
- Acrew Capital: Acrew Capital is a multi-manager, multi-check venture platform where operators write checks together into early-stage startups — a structure that closely mirrors PrimeSet's collective of senior engineers co-investing alongside tier-1 VCs.
- Pioneer Fund: Pioneer is a community-of-operators fund where hundreds of operators invest and provide hands-on support to early-stage founders, structurally similar to PrimeSet's network of distinguished engineers and leaders.
- On Deck: On Deck runs curated founder, operator, and talent communities and connects members with opportunities at venture-backed startups — directly comparable to PrimeSet's private careers platform and founder network.
- Antler: Antler is a global founder-generation platform that co-invests and pairs early-stage founders with experienced operators and advisors, comparable to PrimeSet's combination of investment activity and operator-driven founder support.
- AngelList: AngelList operates both a roll-up vehicle for syndicates/angel investing alongside VCs and a talent platform connecting operators with startups — overlapping with PrimeSet's co-investment and private careers activities.
- South Park Commons: South Park Commons is a community of operators and technical founders that supports members building or joining early-stage companies — comparable to PrimeSet as a curated network of senior engineers and leaders.
Emerging players
- Contrary: Contrary runs research, fellowships, and a venture community targeting student and early-career operators and investors — overlaps with PrimeSet's operator-driven investment network, though skewed earlier in career stage.
Broad incumbents
- First Round Capital: First Round is an established seed VC known for deep founder community and network-driven portfolio support; overlaps with PrimeSet on the founder-support and operator-network axes but is a single fund, not an operator collective.
- Sequoia Capital: Sequoia is a tier-1 VC with extensive founder community programs (e.g., Arc, talent networks) — comparable to PrimeSet on the privileged talent access and founder support axes but as part of a much broader institutional platform.
- Y Combinator: Y Combinator is the largest startup accelerator with a vast mentor network and community, comparable to PrimeSet in offering founders access to experienced operators — though operating at vastly greater scale and as an accelerator rather than an investor collective.
