Why we run four models
Founders often collapse “studio,” “fund,” “incubator,” and “accelerator” into one label. Those labels describe different jobs. Market chooser guides commonly contrast incubators (open-ended space and mentorship, little or no equity), accelerators (fixed cohorts with Demo Day, often single-digit equity for a small check), and venture studios (Day-zero co-builds with large studio equity). That framing leaves our practice vague: we are a Berlin family office and studio with four clear doors, not a single program brand. We keep the distinctions sharp so you can ask for the right engagement instead of forcing every conversation into a raise. For studio versus classic incubator framing, see venture studio vs incubator. For studio versus cohort accelerator and studio versus VC fund, see studio vs accelerator and studio vs VC.
As a private family office and venture studio headquartered in Berlin, we design, fund, and scale technology companies across health tech, AI, e-commerce, and automation. Some teams need an institutional check and operator support on a live round. Others need help turning a validated idea into a company before they raise. Some already ship and need senior builders embedded. Corporates and funds sometimes need board-level product and technical judgment without a check. One firm, four clear doors. For the family-office posture, see family office at Halfmeyer.
Investment
Halfmeyer Ventures investment is capital at pre-seed and seed, usually in the €25,000–€200,000 ticket range, into founder-owned companies. From Berlin, we can join as an early co-investor or as the sole institutional check when round size and fit align. Beyond the money, portfolio companies get design, engineering, and go-to-market playbooks from day one. That is the studio posture on this door: we evaluate whether operator support compounds the company, not only whether the market slide looks large. Investment is one of four engagement doors at our family office and venture studio. It is not incubation, embedded acceleration, or advisory. Cold submissions are welcome; we respond within 48 hours.
As of 2026, market venture-studio explainers still frame studios mainly as Day-zero co-builds that recruit founders into studio-owned ideas at large equity bands (often roughly 30% to 50% or higher). That framing leaves our investment door vague. Investment at Halfmeyer Ventures is a dilutive check into companies founders already own or are building, on disclosed SAFE, convertible, Wandeldarlehen, or priced equity terms. We do not publish a house studio equity percentage table for this door. Studio support ships with the check; intensity depends on the deal. See how much equity and external founders.
Choose investment when you are raising pre-seed or seed, you have a working product, prototype, or validated problem–solution fit, and you want capital plus studio support in health tech, AI, e-commerce, or automation. Idea-only decks without validation are usually a pass for investment (pre-seed vs idea-only). Our checks are dilutive equity instruments; rounds that are exclusively non-dilutive with no equity tranche are not an investment fit (non-dilutive / RBF-only). If you are still becoming a company, ask for incubation. If you already ship and need builders embedded without (or before) a raise, ask for acceleration. If you want product or technical judgment without a check, ask for advisory.
Name investment clearly in your deck or pitch form so we route correctly. State total raise, use of funds, timing, proposed instrument and key terms, and where a €25k–€200k cheque sits (sole check, syndicate slice, or open allocation). Do not assume the top of the band. Full guides: how to state the ask, beyond the check, lead vs follow, and instruments. Sector theses: health tech, AI, e-commerce, automation. If you want a Berlin family office and venture studio investment conversation at €25k–€200k, submit your deck. We respond within 48 hours.
Incubation
Halfmeyer Ventures incubation is for teams moving from idea toward an incorporated entity. From Berlin, we help with problem–solution validation, initial UX, scalable architecture, incorporation mechanics, early hires, and first customer conversations. You do not need an active fundraising round to start an incubation conversation. Cold submissions are welcome; we respond within 48 hours.
As of 2026, market incubator-versus-studio chooser guides still frame incubators as open-ended workspace and mentorship with little or no equity, while venture studios are Day-zero co-builds that recruit founders into studio-owned ideas. That framing leaves our incubation door vague. Incubation at Halfmeyer Ventures is one of four engagement paths at a Berlin family office and venture studio, not a classic coworking program and not a substitute label for the whole firm. It is also not the same as our €25,000–€200,000 investment check at pre-seed and seed. For studio versus classic incubator framing, see venture studio vs incubator.
Choose incubation when the company still needs to become a company: structure, product surface, and early commercial proof before institutional capital is the right next step. Incubation is not a substitute for a raise when you already have a product and a priced or convertible round in market. Idea-only decks without validation are usually a pass for investment, but incubation and advisory can start earlier (pre-seed vs idea-only). Pre-incorporation founders can cold pitch and may route toward incubation when incorporation is still ahead (not yet incorporated). If you are not raising yet, see not raising yet.
Note incubation clearly in your deck or pitch form so we route the conversation correctly. Name the outcome you want (validation, UX, architecture, incorporation, early hires, or first customers). We do not publish fixed incubation equity percentage tables or program calendars. Scope stays case by case. If you later open a dilutive round that fits health tech, AI, e-commerce, or automation, you can return with an investment pitch. If you need a Berlin venture studio incubation conversation before a raise, submit your deck. We respond within 48 hours.
Acceleration
Halfmeyer Ventures acceleration is embedded senior product and engineering talent for startups that already exist. From Berlin, we plug into your roadmap as a fractional strike team: ship critical features, harden infrastructure, and refine revenue models when the founding team is capacity-constrained. Typical outcomes land in weeks, not quarters. This is one of four engagement doors at our family office and venture studio. It is not a cohort accelerator with a Demo Day calendar, and it is not a fee-for-service agency SOW as the product. Cold submissions are welcome; we respond within 48 hours.
As of 2026, market guides still blur three different products. Cohort accelerator choosers sell fixed batches, mentorship, and Demo Day. Co-build versus “acceleration studio” explainers often treat acceleration as a cash vendor that assigns engineers for a retainer with little or no equity. Fractional CTO primers emphasize part-time technical judgment without owning the build. Our acceleration door is different: hands-on build support timed to the company’s real bottlenecks, for teams that already ship. We do not publish day-rate catalogues, hours-per-week packages, or engagement fee cards. Scope stays case by case. For studio versus cohort accelerator, see studio vs accelerator. For studio versus product agency, see studio vs agency.
Choose acceleration when shipping velocity or technical depth is the constraint, not when you primarily need a check to close a round. Acceleration can fit without a live fundraise (not raising yet). If you need both capital and builders, say so: investment (€25,000–€200,000 at pre-seed and seed with design, engineering, and GTM playbooks) and acceleration can sit in the same relationship when stage and ticket fit, but they remain different asks and should be named separately in the deck. Name acceleration in your submission, then submit your deck. We respond within 48 hours.
Advisory
Halfmeyer Ventures advisory is product strategy, technical due diligence, and org design from Berlin. We work with corporates and funds at board level when they need operator judgment without an investment mandate. Founder teams can also ask for structured product or technical guidance outside a raise. Advisory is one of four engagement doors at our family office and venture studio. It is not the €25,000–€200,000 investment check at pre-seed and seed, and it is not embedded builders as the product. Cold submissions are welcome; we respond within 48 hours.
As of 2026, market studio chooser guides still collapse labels into Day-zero co-builds, open-ended workspace incubators, or fixed cohort Demo Days. Co-building versus advising explainers often treat advising as a light retainer with no execution ownership, while co-building owns the build. That framing leaves our advisory door vague. Advisory at Halfmeyer Ventures is judgment and scoped operator support without forcing a raise, a cohort program, or a studio-owned company. We do not publish advisory fee cards, retainer catalogues, or fixed advisory equity percentage tables.
Choose advisory when the primary need is product strategy, technical diligence, or org design, not a check and not a fractional strike team on the roadmap. If you want capital, submit as an investment pitch (€25,000–€200,000 with design, engineering, and GTM playbooks when stage and ticket fit). If you need builders embedded to ship, ask for acceleration. If you are still becoming a company, ask for incubation. Advisory does not replace lean investment diligence after a founder call for companies seeking a check. For transaction-facing software due diligence and Gutachten, see software due diligence and Evaluation vs investment diligence.
Name advisory in your deck or pitch form so we route correctly. Describe the decision or output you need and whether you are a corporate, fund, or founder team. If you later open a dilutive round that fits health tech, AI, e-commerce, or automation, you can return with an investment pitch. For a Berlin family office and venture studio advisory conversation without a check, submit your deck. We respond within 48 hours.
Which model fits you
Use this as a practical chooser, not a rigid taxonomy:
- Investment: you are raising pre-seed or seed, you have product or validated fit, and you want capital plus studio support in health tech, AI, e-commerce, or automation (see investment).
- Incubation: you are pre-company or pre-product in a meaningful sense, and you need help validating, shaping UX and architecture, incorporating, and reaching first customers before a raise (see incubation).
- Acceleration: you already have a startup and need embedded senior product or engineering capacity to harden infrastructure, ship faster, or refine how you make money (see acceleration).
- Advisory: you are a corporate, fund, or founder team seeking product strategy, technical diligence, or org design without asking for a check in this conversation (see advisory).
If two models seem close, pick the primary outcome you need in the next ninety days and name it in the submission. Ambiguous “help us somehow” pitches slow everyone down. Clear engagement intent speeds a useful answer. If you are not raising a round right now, see not raising yet.
Not raising yet
Halfmeyer Ventures still wants to hear from founders who are not raising a pre-seed or seed round right now. Incubation and advisory engagements do not require an active round. Acceleration can fit existing startups that need embedded senior product or engineering without a live fundraise. Investment is the path that assumes capital is in market or about to be: typically €25,000–€200,000 at pre-seed and seed with studio support beyond the check. Cold submissions are welcome either way; we respond within 48 hours.
Europe readiness guides often tell founders to stay away from investors until they are “fundable,” or to join equity-free programs first. That advice misses operators who run more than one door. If you are pre-company or pre-product and need validation, UX, architecture, incorporation, early hires, or first customers, ask for incubation. If you want product strategy, technical diligence, or org design without a check, ask for advisory. If you already ship and need builders embedded, ask for acceleration. Do not force an investment ask when you are not raising; name the non-capital path in the deck or pitch form so we route correctly.
When you later open a dilutive round that fits health tech, AI, e-commerce, or automation, you can return with an investment pitch. Idea-only decks without product, prototype, or validated problem–solution fit remain a pass for investment; earlier work still belongs on the incubation or advisory door. For stage labels, see what pre-seed means. For the cold path end to end, see how to pitch Halfmeyer. If you are not raising yet and need a Berlin venture studio conversation on incubation, acceleration, or advisory, submit your deck. We respond within 48 hours.
Venture studio vs incubator
Halfmeyer Ventures is a Berlin family office, venture studio, and early-stage investor, not a classic workspace incubator. As of 2026, market chooser guides still frame incubators as open-ended space and mentorship with little or no equity, accelerators as fixed cohorts trading roughly single-digit equity for a small check and Demo Day, and venture studios as Day-zero co-builds that recruit founders into studio-owned ideas at much larger equity bands. That framing leaves our practice vague. When we invest, the typical ticket is €25,000–€200,000 at pre-seed and seed, with design, engineering, and go-to-market playbooks beyond the check. Incubation is one of four engagement doors, not a substitute label for the whole firm. We do not publish fixed studio-versus-incubator equity percentage tables; investment terms stay case by case inside the dilutive instruments we accept.
Our incubation path is for teams moving from idea toward an incorporated entity: problem–solution validation, initial UX, scalable architecture, incorporation, early hires, and first customer conversations. It does not require an active fundraising round. It is also not an open-ended coworking program. External founders with their own companies can still pitch us for investment; we are not limited to studio-originated co-builds. For studio posture versus a cohort accelerator, see venture studio vs accelerator. For external-founder fit, see external founders. For studio versus episodic VC checks, see studio vs VC.
If you need capital with studio support in health tech, AI, e-commerce, or automation, ask for investment. If you are still becoming a company, ask for incubation. If you already ship and need embedded builders, ask for acceleration. If you want product or technical judgment without a check, ask for advisory. Name the door in the deck, then submit at halfmeyer.tech/pitch. Cold submissions are welcome; we respond within 48 hours.
How this differs from a capital-only relationship
A capital-only investor writes a check and stays episodic. We write checks too, but investment at Halfmeyer Ventures is designed for teams that want design craft, engineering rigour, and GTM playbooks in the same relationship. Incubation, acceleration, and advisory exist for moments when capital is not the product you need yet (or at all). For what “venture studio” means in our practice beyond these four doors, see what a venture studio is at Halfmeyer Ventures. For the operator surface that ships with the ticket, see beyond the check.
We do not run open-ended workspace programs, and we do not require a warm introduction to start. Public track record we publish: 20+ investments, 5.6× portfolio ROI, and 100+ products built. Selected portfolio names include Doctario, Debtist, Fideus, Joy_, Papeer, vi Health, Urban Ray, mula., Morgen Health, Sunset, ClearStack, and Protocol Health. Full inventory: track record.
How to start the right conversation
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. Set sharing to view-only for anyone with the link (view-only link permissions). In the deck or link context, state which model you are asking for: investment, incubation, acceleration, or advisory. For investment, include stage-appropriate traction, round terms, and sector fit. For non-investment paths, describe the problem, current state, and the outcome you want from working with us. Full deck guide: deck expectations.
Cold submissions are welcome. We review every deck personally and respond within 48 hours. Interested paths move to a founder call and next steps; passes are clear. You do not need a full data room on first submit (no data room to pitch). We do not sign NDAs before initial deck review; materials stay confidential (no pre-review NDA). Ten to fifteen focused slides (or an equivalent Notion brief) is enough to start. End-to-end path: how to pitch Halfmeyer.
