How to Start a Rolling Fund

Each quarter forms a new fund entity that invests in whatever the manager deploys into during that period. An LP subscribing in Q1 owns the Q1 fund's portfolio; an LP joining in Q3 owns the Q3 portfolio and has no interest in Q1's companies. That is the single most important thing for investors to understand and the thing most commonly misexplained.

Subscriptions are expressed per quarter — $25,000 a quarter rather than $100,000 committed — with a minimum subscription period, commonly 4 quarters. After that an LP may cancel with notice. Your deployable capital is therefore a rolling estimate rather than a known figure, which changes how you can commit to founders.

Under Rule 506(b) you cannot generally solicit — no public posts, no open webinars, no newsletter announcement to people you have no prior relationship with. Under 506(c) you can market openly, provided every investor is verified as accredited.

That is why rolling funds cluster around managers with audiences. If your LP pipeline comes from a podcast with 40,000 listeners or a newsletter with 15,000 subscribers, the ability to say publicly that the fund is open is worth more than the structural drawbacks. If your investors are 20 people you already know, the structure adds complexity and takes away committed capital in exchange for an advantage you do not need.

A traditional seed fund reserves 30% to 50% of committed capital for follow-ons because it knows the total. A rolling fund does not know what next year's subscriptions will be, so reserving against future capital means promising a company money you may not have.

Managers handle this in different ways — reserving within each quarterly fund, raising SPVs for follow-ons, or simply not following on and accepting dilution. Each has a real cost, and none is as clean as a committed reserve pool. Be explicit about which approach you use, because sophisticated LPs will ask, and 'we'll figure it out' is a visible answer.

The related constraint is deal size. A quarter that raises $400,000 cannot lead a $2 million round. Managers running rolling funds are usually writing smaller checks and participating rather than leading, which shapes what ownership they can build.

The Fund Builder models the economics across the quarterly structure — subscription levels, deployment pace, fee accrual over the 10-year horizon, and the carry — so what you show prospective LPs matches what the documents say. Legal Canvas prepares the formation and offering documents for independent counsel review, with the 506(c) verification requirements and the quarterly mechanics carried as disclosures.

Because a rolling fund markets publicly, the fund site and deck are load-bearing in a way they are not for a 506(b) raise — they are the offering surface, and Scroll Deck builds both from the same record as the model.
