The short answer
Founders often ask six related questions: Will you co-invest? Do you lead rounds? Do we need a lead first? Can you be a first institutional check? Can you write the only institutional check? Can you join a rolling close?
- Co-investment: yes. We regularly join rounds with angels, seed funds, and family offices.
- Lead rounds: yes, we can lead or follow. We typically participate as an early co-investor or sole backer inside €25k–€200k. See do we lead rounds.
- Other lead required: no. We do not require another lead to engage, review a deck, or start diligence.
- First institutional check: yes, when we can be an early institutional name while you still fill allocation, or when the raise fits a sole institutional check inside €25k–€200k. See first institutional check.
- Sole institutional check: yes, when ticket, stage, and company fit align with €25k–€200k at pre-seed or seed. See sole institutional check.
- Rolling close: yes, when capital is landing investor-by-investor and open allocation still fits a €25k–€200k cheque. See rolling close.
Syndicated rounds are welcome. In the deck, note committed capital and the open allocation you still need to fill. For who we back across sectors, see our Berlin pre-seed investor guide. For the cold pitch path end to end, see how to pitch Halfmeyer.
How we join a round
We invest at pre-seed and seed into software-led companies in health tech, AI, e-commerce, and automation, with design, engineering, and go-to-market playbooks beyond the check. Our typical ticket is €25,000–€200,000. That size often sits next to angels and other early funds rather than replacing an entire round. Co-investment is therefore a normal path, not an exception.
We are not a specialty fund that only shows up after a larger lead has priced and closed the process. As a private venture studio headquartered in Berlin, we can engage early: as a co-investor in a forming syndicate, as a first institutional check while you assemble the rest of the round, or as the sole institutional check when the raise fits our ticket. Incorporation does not need to be German: UK, US (including Delaware), Swiss, and other jurisdictions work when product, market, and round structure fit.
What we care about is fit and clarity, not whether you already have a famous lead. Soft verbal interest from other investors is useful context; signed commitments and remaining allocation are better. If capital is still open, say so plainly. For investment criteria, see what we look for. For how we define stage, see what pre-seed means.
Do we lead rounds?
Halfmeyer Ventures can lead or follow at pre-seed and seed from Berlin. Founders asking “do you lead rounds?” usually want to know whether we set terms, take a board seat, and fill most of the raise, or whether we only join after a larger fund has already priced. Our posture is simpler: we typically participate as an early co-investor or sole backer inside €25,000–€200,000. We can lead or follow. You do not need another lead already committed before you pitch us. Cold submissions are welcome; we respond within 48 hours.
Europe “who leads pre-seed” listicles often treat lead as a priced fund that sets valuation and runs the syndicate calendar. At our ticket, lead more often means early conviction capital with studio support (design, engineering, and go-to-market playbooks) while the round is still forming, or being the sole institutional check when the raise fits the band. It does not mean we always price a full equity round alone, always take a board seat, or always fill every euro of allocation. At pre-seed and seed we rarely take a full board seat; operator support is the posture we prioritize.
In the deck, say whether you need us to lead a forming round, join beside a lead already soft-circled or signed, or write the sole institutional check inside €25k–€200k. Name open allocation, instrument path (SAFE, convertible, Wandeldarlehen, or priced equity), and what product or prototype proof this round unlocks. Soft verbal interest elsewhere is useful context; committed capital and remaining allocation are better. For first institutional framing, see first institutional check. For sole check and rolling close, see those sections. For ticket framing, see ticket size. If you want a Berlin venture studio that can lead or follow inside €25k–€200k without requiring another lead first, submit your deck. We respond within 48 hours.
First institutional check
Halfmeyer Ventures can write a first institutional check at pre-seed and seed from Berlin. Founders usually mean one of two things: the first fund or studio name on a forming round while angels and other capital still fill allocation, or the only institutional check in a smaller raise. Both can fit our €25,000–€200,000 ticket when stage, sector, and operator fit are clear. You do not need another lead already committed before you pitch us. Cold submissions are welcome; we respond within 48 hours.
Europe micro-fund pages often market “first institutional check” with warm intros and committee calendars. Our posture is simpler: we engage as an early co-investor or sole backer, join rounds alongside angels, seed funds, and family offices, and do not require another lead to review a deck or start diligence. If we would be the first institutional name while you keep filling the round, say that plainly. If we would be the sole institutional check inside the ticket band, say that too. Soft verbal interest elsewhere is useful context; committed capital and open allocation are better.
In the deck, state total raise and open allocation for a €25k–€200k-scale participant, who else is soft-circled or signed (or that none are yet), the proposed instrument (SAFE, convertible, Wandeldarlehen, or priced equity), and what product or prototype proof this round unlocks. First institutional check is not a promise that we always lead pricing, take a board seat, or fill the entire round alone. At pre-seed and seed we rarely take a full board seat; operator support is the posture we prioritize. For the sole-check case, see sole institutional check. For ticket framing, see ticket size. If you want a Berlin venture studio that can be an early institutional name on your cap table, submit your deck. We respond within 48 hours.
When we are the sole institutional check
Halfmeyer Ventures can be the sole institutional check at pre-seed and seed from Berlin. Some rounds are small enough that one institutional cheque of €25,000–€200,000, sometimes with angels around it, is the whole raise. That can fit when stage, sector, use of funds, and operator fit align with our ticket. You do not need a second institutional name before we engage, review a deck, or start diligence. Cold submissions are welcome; we respond within 48 hours.
As of 2026, founder-facing Europe pre-seed and check-size guides commonly assume multi-investor syndicates (often three to six or more participants) and rounds sized well above a single €25k–€200k studio ticket, or they steer founders to assemble angels first and add an institutional name later. That framing leaves sole institutional checks sounding incomplete. Our posture is simpler: when the raise fits the band, we can write the only institutional cheque. Angels around that check are fine. A larger priced lead is not required. Sole check is also distinct from being a first institutional check while allocation is still filling with other funds.
Sole check does not mean we replace founder judgment on terms, always price a full equity round alone, or always take a board seat. At pre-seed and seed we rarely take a full board seat; observer rights are possible when they add value without board overhead. Governance is agreed case by case with founders and any co-investors. Operator support (design, engineering, GTM) is the posture we prioritize over formal seats. In the deck, state total raise, that you are seeking a sole institutional check inside €25k–€200k (or name angel participation if any), the proposed instrument, use of funds, and what product or prototype proof this round unlocks. For how to state the ask, see state the ask. For studio posture, see venture studio. If you want a Berlin family office and venture studio that can be the only institutional name on a €25k–€200k-scale raise, submit your deck. We respond within 48 hours.
Rolling close (investor-by-investor)
Halfmeyer Ventures can join a rolling close at pre-seed and seed from Berlin. A rolling close means investors sign and wire on their own timing, usually on SAFEs or other convertibles, while you keep filling open allocation. You do not need a single hard close date, a priced lead already locked, or another institutional name committed before you pitch us. Cold submissions are welcome at halfmeyer.tech/pitch; we respond within 48 hours.
Market guides contrast rolling SAFE closes with hard closes gated by a priced lead. Our posture is simpler: we regularly join rounds alongside angels, seed funds, and family offices, and we can be a first institutional check or the sole institutional check inside €25,000–€200,000 when stage and fit align. We do not require another lead to review a deck or start diligence. If capital is landing investor-by-investor and allocation remains open for a €25k–€200k-scale participant, say that plainly. Soft verbal interest elsewhere is useful context; committed capital and remaining allocation are better.
In the deck, state total raise, open allocation, who is soft-circled or signed (or that none are yet), the proposed instrument (SAFE, convertible, Wandeldarlehen, or priced equity), and what product or prototype proof this round unlocks. Rolling close is not a promise that we always wire first, fill the entire round, or take a board seat. At pre-seed and seed we rarely take a full board seat; operator support is the posture we prioritize. Instrument choice alone is not a pass reason; clarity on terms matters. For SAFE versus Wandeldarlehen, see our instruments guide. For ticket framing, see ticket size. If you are filling a rolling pre-seed or seed round and want a Berlin venture studio cheque inside €25k–€200k, submit your deck. We respond within 48 hours.
What to disclose in the deck
Round clarity helps us respond within the 48-hour window without a guessing game. In your first-pass deck, include:
- Amount: how much you are raising now, and whether this is a new round, a bridge, or an extension.
- Use of funds: what the capital unlocks in the next 12–18 months (product, hires, GTM, runway).
- Instrument and timing: SAFE, convertible, Wandeldarlehen, or priced equity, plus target close timing. We are flexible across those instruments; state what you are proposing.
- Committed capital: named angels, funds, or family offices that are soft-circled or signed, with amounts if you can share them.
- Open allocation: how much of the round remains to fill, and the ticket size you are targeting from us.
You do not need a full data room on first submit. Ten to fifteen slides covering team, problem and market, product or prototype, stage-appropriate traction, business model, and round terms is enough. Set the link to view-only for anyone with the link. For slide mechanics and link rules, see pitch deck expectations. Our investment checks are dilutive equity instruments; rounds that are exclusively non-dilutive with no equity tranche are not an investment fit.
Diligence when other investors are involved
We review every deck personally and respond within 48 hours with a founder call path, clarifying questions by email, or a clear pass. After a productive call, diligence typically runs one to two weeks: product walkthrough, key metrics, reference calls if useful, and term alignment with co-investors. We keep that process lean at pre-seed and seed. Clear proceed, pass, or term-sheet direction is the goal inside that window.
If you already have co-investors in diligence or soft-circled, tell us early. It speeds term alignment and avoids duplicate asks. We do not sign NDAs before initial deck review; pitch materials stay confidential and are not shared externally. A mutual NDA is possible later when diligence requires sensitive IP. Bridge and extension rounds between priced equity rounds can fit when stage, traction, and ticket align; explain the bridge rationale and the milestones the capital unlocks. Portfolio follow-ons for companies we already backed are considered when traction, execution, and terms warrant it; they are not automatic.
How to pitch when you need a co-investor
Submit at halfmeyer.tech/pitch. Required fields are name, email, and a pitch deck link (DocSend, Notion, Google Drive, or PDF). Company name is optional. Cold submissions are welcome; you do not need a warm introduction or a pre-committed lead. State sector fit (health tech, AI, e-commerce, automation, or a clear adjacent software surface) and name whether you want investment, incubation, acceleration, or advisory. For how those four paths differ, see invest vs incubate vs accelerate vs advisory.
If your round is already partly filled, say what is committed and what remains. If you are looking for a sole institutional check inside €25k–€200k, say that too. Either framing is fine; unclear round math is what slows a first response. We back founders across Europe and beyond from Berlin. Public track record we state: 20+ investments, 5.6× portfolio ROI, and 100+ products built. Use those as entity facts, not as promises about your syndicate.
