Incubators & Accelerators guides

Concepts

Cohort

The group of companies moving through a program together. Cohort size sets the economics on both sides — more companies means more shots on goal for the program and less partner attention per founder.

Batch

One time-boxed run of a cohort-based program, usually 3-6 months with a fixed start and a demo day at the end. 'Batch' and 'cohort' are used interchangeably, though batch emphasizes the calendar and cohort emphasizes the group.

Demo day

The closing event where a batch pitches investors. Its real function is manufacturing a compressed fundraising window — many companies at once, all raising in the same two weeks, which creates urgency no solo raise can.

Pitch day

A competitive pitch event that is not attached to a program cohort — SXSW Pitch is the best-known example. Selection, judging and prizes replace curriculum; the payoff is exposure and investor contact, not equity investment.

Standard deal

A program's published, non-negotiable investment terms, offered identically to every company in the batch. Y Combinator's is the reference point: $500,000 total, structured as $125,000 on a post-money SAFE for 7% plus $375,000 on an uncapped SAFE with an MFN provision, and no fees charged to companies.

SAFE

Simple Agreement for Future Equity — the standard instrument for accelerator investment. It converts to stock at a future priced round rather than being equity or debt today, which is why programs can invest without setting a valuation.

Post-money SAFE

A SAFE whose cap is set on the post-money valuation, so the investor's percentage is fixed and known at signing and later SAFEs dilute the founders rather than the earlier SAFE holder. The dominant form since 2018 and the reason stacked SAFEs now produce predictable, and sometimes brutal, founder dilution.

MFN (Most Favored Nation)

A provision letting an uncapped SAFE holder adopt the terms of any better SAFE the company issues before a priced round. It lets a program invest without pricing the company — the second tranche of YC's $375,000 works this way.

Pro rata rights

The right to invest again in later rounds to maintain ownership percentage. For a program this is where most of the eventual return lives — the initial batch check is small; the follow-on right on the winners is the asset.

Dilution from program equity

The permanent ownership cost of a program seat. A 6-8% bite before a priced round compounds through every later round; the honest test is whether the program's introductions and follow-on rate raise the company's outcome by more than that percentage.

Equity-free grant

Cash given with no ownership taken — typical of nonprofit, university, corporate-sponsored and economic-development programs. DivInc, for example, reports distributing $300K in equity-free grants to its portfolio.

Non-dilutive funding

Any capital that does not take equity: grants, prizes, SBIR/STTR awards, revenue-based financing, customer prepayments. For hard tech and life science it often exceeds the equity raised in a company's first three years.

SBIR/STTR Phase I and Phase II

Federal small-business R&D awards. Phase I funds feasibility at roughly six figures over 6-12 months; Phase II funds development at roughly seven figures over about two years. STTR requires a formal research-institution partner; SBIR does not.

I-Corps

The NSF's customer-discovery training program, built on running structured customer interviews to test commercial hypotheses before building. Regional I-Corps hubs are run through universities — ATI hosts Southwest I-Corps — and completion is a de facto prerequisite for many federal follow-on awards.

EIR (Entrepreneur in Residence)

An experienced operator embedded in a program or fund, either advising cohort companies or incubating a company to found themselves. In venture studios the EIR track is the primary founder-sourcing pipeline.

Mentor whiplash

The disorientation of getting contradictory advice from many mentors in a short window — the signature failure mode of mentor-driven accelerators. Well-run programs address it explicitly: mentors advise, founders decide, and one lead mentor holds continuity.

Office hours

Scheduled one-to-one sessions between founders and partners or mentors, the core delivery mechanism of most programs. Frequency and who shows up — partners or junior staff — is the most reliable quality signal in a program.

Curriculum

The structured content of a program: sessions on pricing, sales, hiring, fundraising, metrics, legal. Curriculum is the commodity layer — it is what a program can be copied on, unlike its network and its selection.

Milestone-based tranching

Releasing program capital in stages against agreed milestones rather than as one upfront check. Common in corporate, university and grant-funded programs; rare in classic equity accelerators, where the full check lands at the start.

Incubator vs accelerator vs venture studio vs foundry

An incubator houses and supports companies on an open-ended timeline, often with space and often equity-light. An accelerator runs fixed-length cohorts, usually invests, and ends in demo day. A venture studio or foundry originates the idea itself and assembles the team, taking a large founding stake. The words are used loosely in marketing — read the terms, not the label.

Studio equity split

The ownership division between a venture studio and the operating founders it recruits. Studios typically hold a large founding position — commonly 30% or more — justified by having supplied the idea, capital, and shared engineering, design and recruiting functions.

Co-founder matching

Programs that back individuals before companies exist and pair them into founding teams during the cohort — the Antler and Entrepreneur First model. Selection is on the person, and the program's core product is a curated pool of potential co-founders.

Sweat equity

Ownership earned through work rather than cash — the founder's own stake, and how advisors and early team are often compensated. It is the reason vesting schedules exist: unvested sweat equity walking out the door is the most common early cap-table disaster.

Vesting and cliff

Founder and employee shares earned over time, standard four years with a one-year cliff, so someone who leaves in month eleven takes nothing. Programs routinely require founders to reset or install vesting as a condition of investment.

IP assignment

The formal transfer of relevant inventions and code from individuals into the company. Diligence killer when missed — code written at a prior employer, or research done on university equipment, can leave ownership genuinely unresolved.

University tech transfer and Bayh-Dole

The Bayh-Dole framework lets universities retain title to inventions made with federal funding and license them out, which is why campus technology-licensing offices exist and why a research spinout's IP usually belongs to the institution before it belongs to the founders.

Licensing agreement

The contract by which a spinout licenses university IP — exclusive or non-exclusive, with upfront fees, royalties, equity, milestone payments and diligence obligations. Terms here shape the company's economics more than any accelerator deal will.

Sponsored research

A company funding work in a university lab, typically with negotiated rights to resulting IP. Common for deep-tech startups that need instrumentation or expertise they cannot yet afford in-house, and a frequent bridge between a campus incubator and a real company.

Wet lab vs dry lab space

Wet lab handles chemicals and biological material and needs benches, fume hoods, casework, waste handling and specific ventilation and permits; dry lab is computation and electronics on ordinary office infrastructure. Wet lab is expensive, scarce and the binding constraint on life-science incubators.

Hard tech vs software program economics

A software batch can be run on a small check, three months and no facilities. Hard tech needs bigger checks, longer runway, prototyping and lab space, so its programs depend on grants, corporate partners, universities or a dedicated fund rather than batch equity alone.

Cohort selection funnel

Applications to screens to interviews to offers to accepted. Each stage's conversion rate tells you where a program's constraint is — weak top of funnel means a marketing problem; weak offer acceptance means it is losing candidates to better programs.

Acceptance rate

Offers divided by applications. Low single digits at the top programs, and heavily marketed as a quality proxy — but it measures applicant volume as much as selectivity, and a program can lower it simply by advertising harder.

Graduation rate

Share of a cohort that completes the program. Near-universal at equity accelerators, where completion is nearly automatic, and genuinely meaningful only at incubators and grant programs that enforce milestones and can remove companies.

Follow-on funding rate

The share of graduates that raise an institutional round afterward, and the metric practitioners treat as the real credibility test of a program — it measures whether the market revalued the company, not whether the program filled seats.

Alumni network

The community of past participants — the compounding asset that distinguishes a decade-old program from a new one. Its practical value is measured in warm intros, hiring, customer referrals and later-round investor access, not in headcount.

Corporate innovation partner

A large company sponsoring or co-running a program to get early access to startups, pilots and acquisition targets. For participants the prize is a procurement pilot inside the sponsor; for the program it is the sponsorship revenue that funds operations.

Sponsorship revenue model

Funding a program from corporate, government and service-provider sponsors rather than from equity returns. It makes a program cash-flow viable immediately and structurally cyclical — sponsorship is a marketing budget line and it gets cut first.

Membership revenue

Recurring fees for access to a program's community, space, events, mentors and investor network without a cohort commitment. Capital Factory's All Access program — roughly 100 companies a year — is the model, and it decouples ecosystem revenue from batch cadence.

Real-estate-subsidized model

An incubator funded by the building it occupies — below-market space from a university, city, developer or corporation, with the program layered on top. Durable, because it survives on rent rather than exits, but it drifts toward being a landlord with programming.

Economic development grant funding

City, county, state and federal money for programs that create local jobs and companies. It pays for equity-free programming, but it comes with reporting obligations, geographic restrictions and political timelines that do not match startup timelines.

MSA / regional cluster strategy

Building a program around a metropolitan statistical area's actual industrial strengths — Houston's medical center, Austin's semiconductor and software base — instead of copying a generalist Silicon Valley batch into a market with no matching deal flow.

Deal flow

The stream of companies a program sees. It is the true scarce input — capital, curriculum and mentors are all purchasable, while a differentiated flow of applicants no other program sees is the only lasting advantage.

Warm intro

An introduction from someone the recipient trusts. Most of what founders are actually buying with program equity is the conversion of cold outreach into warm intros — to investors, to enterprise buyers, and to senior hires.

Pipeline conversion

Movement rates between stages — applicant to accepted, graduate to funded, intro to meeting to term sheet. Programs that instrument this can tell which mentors, sponsors and channels actually produce outcomes instead of activity.

Tuition and tuition offset

Some programs charge founders directly, or net a fee out of the investment. Alchemist, for example, reports an average net investment to companies of about $30,000 after tuition offset. Any program charging tuition should be judged as a paid service, not as an investor.

What’s happening

• The accelerator field consolidated hard after the 2021 correction. Techstars — which at its peak operated more than fifty programs — listed roughly sixteen accelerators as of August 2026, having wound down city and corporate-partner programs including its Austin and Seattle operations in 2024. Program count, not company count, is where the contraction shows. 2026-08 source ↗
• Austin's Newchip, once one of the largest remote-first accelerators with a claimed portfolio in the thousands, collapsed through 2023 bankruptcy proceedings that ended in liquidation. As of 2026 its former newchip.com domain has been re-registered by an unrelated party and serves online-casino affiliate content. There is no active successor program under that name — any current reference to 'Newchip' should be treated as historical, and it is a standing lesson in how quietly a program with a thousand founders in it can disappear. 2026-08 source ↗
• Several well-known programs are now in an ambiguous state rather than an announced closure, which is the field's characteristic failure mode. AngelPad's site states 'The application is currently closed,' with no next cohort dated. MassChallenge's homepage reads 'Please check back for upcoming programming.' Neither has declared a shutdown; neither is visibly running a batch. Verify status before recommending any program. 2026-08 source ↗
• The batch model is losing ground to continuous and membership structures. Capital Factory now positions itself as 'a Texas venture firm — the most active early-stage investor in Texas,' running the Texas Fund alongside an All Access membership that touches roughly a hundred companies a year, rather than a classic fixed-cohort accelerator. Venture studios and day-zero programs like Antler, which reports 1,800+ portfolio companies across about thirty locations, took the other exit from batch economics. 2026-08 source ↗
• AI-native cohorts now dominate recent batches at the top programs, with a large majority of accepted companies building AI products and a growing share of them showing revenue at application because AI tooling collapsed the time from idea to shippable product. The practical consequence for programs is that the traditional 'build it during the batch' curriculum is obsolete for software companies that arrive already launched. 2026-08
• Corporate innovation budgets shrank through the same period, which hit sponsorship-funded programs hardest — corporate-partner accelerators were among the first Techstars programs to be discontinued. Programs dependent on a single sponsor discovered their revenue was a discretionary marketing line, and the survivors diversified into membership, fund management fees or public funding. 2026-08
• University and federal money moved the other direction. The EDA's Regional Technology and Innovation Hubs and Build to Scale programs pushed substantial federal funding into regional cluster building, and university-affiliated incubators — ATI at UT Austin, founded 1989 and the longest continuously operating technology incubator in the US, now spanning circular economy, energy, food and agtech, healthcare, microelectronics, mobility and water — became relatively more important as private program funding tightened. 2026-08 source ↗
• SBIR/STTR remains the backbone of non-dilutive hard-tech funding, but the 2022 SBIR and STTR Extension Act added a foreign-influence due-diligence review and tightened performance benchmarks aimed at repeat-award 'SBIR mills,' and the program's authorization has since run through contested short-term extensions rather than a clean long reauthorization. Applicants face materially more diligence and less schedule certainty than a decade ago — always check sbir.gov for the current authorization status before advising on timing. 2026-08 source ↗
• Equity-free and revenue-based alternatives kept growing as founders did the dilution math on stacked post-money SAFEs. gener8tor now runs free non-dilutive accelerators alongside its $100K investment programs; nonprofit and university programs increasingly lead with equity-free grants; and revenue-based financing has become the default alternative for companies with revenue that do not want a priced round. 2026-08 source ↗
• Remote versus in-person settled toward in-person for the flagship equity programs and remote for everything else. Y Combinator requires founders to be present for the batch; the remote-first accelerators that scaled fastest in 2020-2021 are the same cohort of programs that collapsed or went quiet. Regional and equity-free programs, by contrast, standardized on hybrid delivery because it is how they reach founders outside their metro. 2026-08 source ↗
• Follow-on funding rate has replaced headcount and cumulative-companies-accelerated as the credibility metric practitioners and LPs actually ask about. The shift is visible in how programs present themselves — Alchemist leads with 750+ startups, 70+ acquisitions and $5B+ raised by alumni; SXSW Pitch reports that of 732 companies since 2009 more than 80% secured funding and 22% were acquired. Cumulative totals are still marketed, but a program that cannot state a current-cohort follow-on rate is telling you something. 2026-08 source ↗
• Austin's ecosystem absorbed heavy pandemic-era in-migration of founders and capital, then had to prove the inflow was structural. The durable institutions turned out to be the ones with non-batch funding: Capital Factory on a fund plus membership, ATI on the university, DivInc as a 501(c)(3) reporting $15M+ raised by portfolio companies and $300K in equity-free grants, SKU as a specialist CPG accelerator with alumni including Siete Family Foods and Austin Eastciders, Sputnik ATX still running seasonal cohorts, and Central Texas Angel Network with 233 companies funded and $142.4M invested since 2006. 2026-08 source ↗
• Deal terms standardized around the post-money SAFE, and Y Combinator's published deal is the anchor the whole field prices against: $500,000 as $125,000 on a post-money SAFE for 7% plus $375,000 on an uncapped MFN SAFE, with pro rata rights and no fees. Programs now differentiate on network and sector access rather than on terms, because terms have converged. 2026-08 source ↗
• Deep tech and life science pulled away from software program economics entirely. HAX relocated its hard-tech program to Newark with state and institutional backing; IndieBio, Activate and university wet-lab incubators run on facilities, fellowships and grants rather than three-month batch equity; and TMC's Houston programs rebranded TMCx to HealthTech alongside device and therapeutics accelerators. The lesson programs learned is that a wet-lab company cannot be accelerated on a software calendar. 2026-08 source ↗

Questions people ask

What is the difference between an incubator, an accelerator and a venture studio?

sort them by whether they take equity, run fixed cohorts, provide space, and whether they start the company themselves; those four axes explain almost every other difference

What is a cohort or batch?

a group admitted and run together on one calendar; note that many programmes have moved to continuous or membership models instead

What is demo day?

the programme's investor showcase at the end of a batch; be clear it is a marketing event for both sides, not a funding guarantee

What is a post-money SAFE?

the cap is set after the SAFE money is counted, so the founder's dilution is fixed and known at signing; that shift is the reason stacked SAFEs dilute more than founders expect

What is an MFN clause on a SAFE?

most favoured nation lets the holder adopt better terms given to a later investor; explain that it converts an uncapped note into whatever the next cap turns out to be

What are pro rata rights?

the right to keep investing to hold a percentage in later rounds; describe the effect on a founder's future cap table

What is mentor whiplash?

contradictory advice from many mentors in a short window; the useful framing is that mentors are inputs, not decisions

What is an entrepreneur in residence?

an experienced operator attached to the programme, sometimes looking for their own next company; say that the incentive varies and is worth asking about

How does a venture studio split equity with founders?

studios take a much larger share than accelerators because they supply the idea, the team and early capital; the split is negotiated per studio so describe the range of structures, not a number

What are SBIR and STTR?

federal non-dilutive research funding awarded in phases by agency; note the programme now carries additional due-diligence requirements and has run on short-term authorisations

What is I-Corps?

a federally funded customer-discovery programme, often a prerequisite culture step before SBIR; it is training plus a small grant, not an investment

What is Bayh-Dole and how does university tech transfer work?

it lets universities own inventions from federally funded research and license them out; the licence terms, not the science, are what a spinout negotiates

What does equity-free actually mean for a programme?

no equity taken, but check for warrants, fees, revenue share or a right of first refusal buried in the agreement; equity-free is a claim to verify in the document

How much equity does an accelerator take?

terms have converged around the post-money SAFE but the specific stake differs by programme; point at each programme's published deal instead of quoting a share

What is Y Combinator's standard deal?

YC publishes it openly - a fixed post-money SAFE plus a larger uncapped MFN SAFE, with pro rata and no fees; cite the published deal page and let it carry the numbers

How much am I really diluted by a programme SAFE plus a seed round?

show the stacking method - programme SAFE, batch SAFEs, option pool, then the priced round - and let the founder run it on their own cap table
