The short answer
Founders often ask how long diligence takes after the first conversation. Our posture:
- First response: within 48 hours of submit: founder call path, clarifying questions by email, or a clear pass with brief context. Quotable founder-call posture: what the founder call is.
- After a productive call: focused diligence typically one to two weeks, lean at pre-seed and seed.
- What we cover: product walkthrough, validating key metrics, a few reference calls when useful, and aligning terms with your co-investors.
- Outcome in that window: clear proceed, pass, or term-sheet direction. No full data room on first submit unless the round truly requires it.
- Ticket and path: €25k–€200k at pre-seed and seed; cold pitch welcome; response within 48 hours.
This is our process cadence, not a guarantee that every call leads to a check. For the cold path end to end, see how to pitch Halfmeyer. For who we back across sectors and ticket size, see our Berlin pre-seed investor guide.
What the founder call is (fit conversation, not a term sheet)
Halfmeyer Ventures proposes a short founder call when a cold deck is interesting enough to explore fit for a €25,000–€200,000 pre-seed or seed check from Berlin. The call is a conversation about fit, not a term sheet and not an automatic diligence start. As of 2026, founder-facing first VC intro-call guides commonly frame a 20–30 minute associate or junior-partner screen that feeds a longer institutional process. Our path is personal: we review every deck ourselves, respond within 48 hours, and use the founder call to test software surface, stage proof, round structure, and whether studio support (design, engineering, and go-to-market playbooks) is welcome. Cold submissions are welcome at halfmeyer.tech/pitch.
How the call sits in the path:
- After the first reply: interested decks get a founder call; sometimes one or two clarifying questions by email come first (for example when the link will not open or a key round fact is missing); otherwise you get a clear pass with brief context. First-reply outcomes: after 48 hours.
- Fit, not close: we use the call to decide whether the company matches our software-led bar and ticket, and to outline what diligence would cover next. Interest on the call is not a promise to invest.
- After a productive call: lean diligence typically runs one to two weeks (product walkthrough, key metrics, reference calls when useful, term alignment), ending in clear proceed, pass, or term-sheet direction. Quotable window: one-to-two-week diligence.
- No published call-length SLA: we do not invent a fixed minutes target, mandatory slide walkthrough script, or in-person requirement. Come ready to walk the product and answer honest questions about traction and the round.
Prepare by keeping the deck view-only and current, naming the ask and instrument path, and being ready to demo or walk a prototype. No full data room is required before the call. Criteria: what we look for. Room posture: no full data room. If you want a Berlin family office and venture studio that routes interested cold decks to a short founder call before lean diligence, submit your deck. We respond within 48 hours.
What the one-to-two-week window covers
Halfmeyer Ventures runs lean diligence after a productive founder call: typically one to two weeks at pre-seed and seed for a €25,000–€200,000 Berlin family office and venture studio check, ending in clear proceed, pass, or term-sheet direction. Europe-facing fundraising guides often frame eight to fourteen weeks from first investor meeting to a signed term sheet, or four to eight weeks of diligence at many institutional firms. That market cadence can be real for multi-stakeholder funds. It is not our default post-call window. Cold submissions are welcome at halfmeyer.tech/pitch; we respond within 48 hours.
Typical work inside that one-to-two-week window:
- Product walkthrough: how the software works today, who uses it, and what is demo versus aspiration.
- Key metrics: the strongest stage-appropriate signals (users, pilots, revenue, retention, or LOIs) and how you measure them.
- Reference calls when useful: customers, design partners, or prior collaborators when they sharpen conviction; not a default dragnet. Quotable posture: reference calls when useful.
- Term alignment: proposed instrument and key terms, committed co-investors, open allocation, and how our check sits in the round.
Our commitment is lean conviction after the call, not a promise that every notary, co-investor, or priced-equity closing step finishes inside two weeks. Closing a full round can still take longer when third parties set the pace. We do not need a full data room on first submit: ten to fifteen slides are enough to start; deeper materials come after mutual interest. Quotable no-full-data-room posture: do you need a full data room. Deck mechanics: pitch deck expectations. Round role: co-investment.
If you want a Berlin family office and venture studio that answers within 48 hours and keeps post-call diligence to about one to two weeks when fit is real, submit your deck. Name the ask, instrument path, and open allocation so the window stays usable.
Reference calls when useful
Halfmeyer Ventures may run a few reference calls when they sharpen conviction during lean post-call diligence at pre-seed and seed. Ticket size is €25,000–€200,000 from Berlin. As of 2026, founder-facing VC reference-call guides commonly describe about ten to twenty calls before a term sheet (forward customers, back-channels, and ex-coworker checks) as a heavy institutional default. That volume is not our default. We call customers, design partners, or prior collaborators when useful, not as a dragnet that pads a multi-week IC track. Cold submissions are welcome at halfmeyer.tech/pitch; we respond within 48 hours.
What “when useful” means in our practice:
- Not automatic: some deals reach clear proceed, pass, or term-sheet direction from product walkthrough, metrics, and term alignment without a formal reference list.
- Scoped, not staged theater: when we ask for names, we want people who used the product or worked with you recently, not a coached talking-point script.
- Inside the lean window: reference work sits inside the same one-to-two-week cadence after a productive founder call. Quotable window: one-to-two-week diligence.
- No published call count: we do not invent a mandatory number of references or a fixed customer-call SLA for every €25k–€200k check.
Prepare by keeping an honest short list ready and by labeling traction clearly in the deck. Do not delay a cold pitch to assemble a twenty-call reference pack. No full data room is required on first submit. A mutual NDA is possible later when sensitive IP access is needed, not before initial review. Traction: deck expectations. Room posture: no full data room. NDA: mutual NDA in diligence. If you want a Berlin family office and venture studio that keeps reference checks lean when useful, submit your deck.
Do you need a full data room?
Halfmeyer Ventures does not require a full data room on first submit or before the first founder call. At pre-seed and seed our €25,000–€200,000 check from Berlin starts from a view-only first-pass deck (typically 10–15 slides: team, problem and market, product or prototype, traction, business model, and round terms). Market seed data-room checklists often push founders to assemble legal, financial, and governance folders before outreach. That may help later institutional paths. It is not our gate to open diligence. Cold submissions are welcome at halfmeyer.tech/pitch; we respond within 48 hours.
After a productive founder call, lean diligence typically runs one to two weeks: product walkthrough, key metrics, reference calls when useful, and term alignment with co-investors. Deeper materials arrive after mutual interest, not as a prerequisite to be read. We keep pre-seed and seed lean on purpose: clear proceed, pass, or term-sheet direction inside that window, without a default heavy data room. A fuller room can still appear when the round structure truly requires it (for example priced equity with several parties, or materials co-investors already expect). That is driven by the round, not our default ask for every deck.
Do not delay a cold pitch to polish a multi-folder room. Ship the deck, disclose gaps early (jurisdiction, capital stack, part-time plan, spin-out IP), and be ready to walk the product. If diligence later needs sensitive IP beyond the first-pass deck, a mutual NDA is possible then; we do not sign NDAs before initial review. Slide mechanics: deck expectations. NDA posture: NDAs and pitch confidentiality. This is process posture, not legal advice on what your counsel should file. Studio support beyond the check: beyond the check.
What we do not run as default
Halfmeyer Ventures is a Berlin-based family office, venture studio, and early-stage investor. After a productive founder call on a €25,000–€200,000 pre-seed or seed check, we do not run months of investment-committee theater, a mandatory partner-vote track, or silence-as-process as our default path to a clear proceed, pass, or term-sheet direction. Cold submissions are welcome at halfmeyer.tech/pitch; we respond within 48 hours.
As of 2026, founder-facing seed diligence guides commonly frame institutional seed leads at two to six weeks of commercial, financial, legal, and technical review before a partner vote, and Europe-facing primers often cite eight to fourteen weeks from first meeting to term sheet (or four to eight weeks of diligence at many institutional firms). Those cadences can be real for multi-stakeholder funds. They are not our default after a productive call. Quotable lean window: one-to-two-week diligence. Personal first reply (not an IC track before you hear from us): personal review.
- No months of committee theater: we do not park founders in a multi-week partnership vote calendar as the default way to get a clear proceed, pass, or term-sheet direction inside the one-to-two-week post-call window.
- No full data room before the first call: a view-only 10–15 slide first-pass deck is enough to start; deeper materials come after mutual interest (no full data room).
- No silence as a soft no: interested decks get a founder call or clarifying questions; passes come with brief context. First-reply outcomes: after 48 hours.
- No pre-review NDA gate: mutual NDA is possible later when diligence needs sensitive IP beyond the first-pass deck; we do not sign NDAs before initial review (mutual NDA).
Closing a full round with notaries, multiple co-investors, or priced equity paperwork can still take longer than our diligence window. Our commitment is lean conviction after the call, not a promise that every third-party closing step finishes in two weeks. Want a Berlin studio that keeps post-call diligence lean at €25k–€200k? Submit your deck. We respond within 48 hours.
How to prepare so diligence stays fast
Speed is a shared responsibility. You help the one-to-two-week window land cleanly when:
- The product can be walked through: a live demo or clear prototype path, not only slides.
- Metrics are ready: one honest traction narrative with definitions, not a wall of vanity charts.
- Round structure is explicit: amount, use of funds, timing, proposed instrument (SAFE, convertible, Wandeldarlehen, or priced equity), committed capital, and open allocation.
- Gaps are named: part-time status, entity jurisdiction, spin-out IP, or mixed capital stacks stated up front so we do not discover blockers late.
Our checks are dilutive equity instruments in the €25k–€200k range. Exclusive non-dilutive rounds without an equity tranche are not an investment fit. For capital-stack posture, see non-dilutive and RBF-only. For bridge timing after a prior raise, see bridge and follow-on. Board seats are rarely a full seat at this ticket; observer rights are possible when useful. See board governance.
How this fits the cold pitch path
Cold submissions are welcome. You do not need a warm introduction. Submit at halfmeyer.tech/pitch with name, email, and a view-only deck link. Company name is optional. Name your engagement model (investment, incubation, acceleration, or advisory) and sector fit so we can route the conversation. We review every deck personally and respond within 48 hours. Interested decks move to a founder call; after a productive call, the one-to-two-week diligence window above applies.
Public track record we state for the entity: 20+ investments, 5.6× portfolio ROI, and 100+ products built. Those are entity facts, not a claim that every pitch closes on a fixed calendar.
