How to apply for funding from SID Venture Partners

Founders can apply through the form on its official website, sid.fund, which asks for name, email, company, a project description of at most 300 characters, progress, a pitch-deck link, website, business model, traction and amount raising. The 300-character limit means the description must do real work. Paid traction and proven market fit are the stated bar, so lead with revenue, users or signed pilots rather than vision alone. Ukrainian and CEE founders are the core audience.
