SaaS accelerators: the B2B and SaaS programs, and what each one asks of you

These accelerators on our list say on their own pages that they back SaaS, B2B or enterprise software. TinySeed is built for SaaS businesses that already earn revenue, and runs remotely for a year. Forum Ventures funds pre-seed B2B software in any vertical. Startup Wise Guys takes B2B startups and turns away B2C. Alchemist backs companies whose revenue comes from enterprises. Dreamit invests in cybersecurity, fraud, risk and compliance companies that already have traction.

If you came here for a TinySeed alternative, timing may be the reason: TinySeed has no fall 2026 batch, and its program page says applications open again in February 2027. This guide quotes what each one says about who it takes, as we read their pages on 2 October 2026, and links to the pages where their terms are compared.

01The programs side by side

"Terms" is each program's check in the short form our posters use; Alchemist's cell says "Equity" because it asks for a stake but states no check. Hover a cell for the full sentence. What each deal costs you in equity, with the arithmetic, is in how much equity accelerators take.

02TinySeed: for SaaS that already earns

TinySeed is the one program here built only for SaaS. Its program page, as we read it on 2 October 2026, says the year-long program is "designed to help founders with a revenue-generating SaaS optimize product-market fit and grow faster." On who fits: "We focus on SaaS companies that have the potential to become 7- or 8-figure businesses. We accept applications from any stage, but we've found that a couple thousand dollars in monthly revenue is a sign that a founding team has been able to push their business forward."

Three more lines from the same page change the math:

• How it gets paid back. "TinySeed does not take revenue or profit from your company, only dividends that you decide to pull out at timing that works for the business."
• A fee, covered. "Our program fee is $7,450 per founder." The page adds that TinySeed raises your investment by the same amount, so the fee comes out of money it adds.
• The company it invests in. "Currently we only invest in US C-Corps (preferably Delaware)." If you're incorporated elsewhere or not at all, it asks only that you "be willing to reincorporate if you receive an offer." Other programs' rules on where the company must be incorporated are in accelerators for international founders.

On timing, the page says applications open again in February 2027. Its announcement of the paused batch is quoted in how long accelerators take to answer. Its check and stake are in the equity guide, and how its remote year works is in remote accelerators. TinySeed on the list.

03Forum Ventures: pre-seed B2B software

Forum Ventures takes software sold to businesses, at the earliest stage. Its accelerator page (opens in a new tab), read on 2 October 2026: "We fund B2B software companies in any vertical in the early-stage (pre-seed) of your journey who have taken on less than $500k in funding, and have or are about to have an MVP in market."

So it is the opposite end from TinySeed: no revenue needed, but a cap on what you've already raised. Its recent cohorts lean toward AI: the same page links to posts titled "Introducing our Winter 2026 B2B AI-first cohort" and "Forum Ventures Introduces Its Spring 2026 B2B AI-First Cohort". Other AI programs are in AI startup accelerators.

Its fixed stake for a fixed check is compared with Techstars' deal in Techstars alternatives, and its reply time is in the table. Forum Ventures on the list.

04Startup Wise Guys: B2B only, from Europe

Startup Wise Guys draws the line at the customer. Its flagship accelerator page, read on 2 October 2026: "Our programs are meant for B2B startups. We do sometimes work with B2B2C companies, but we do not work with B2C startups." Its site lists SaaS among its verticals, next to cybersecurity, fintech and proptech.

It is the European program in this set (how much of it runs in Tallinn is in accelerators in Europe), and it charges a program cost against its investment; the numbers, with the subtraction, are in the equity guide. Its next deadline is in the Next deadlines strip in room 03. Startup Wise Guys on the list.

05Alchemist: anything sold to enterprises

Alchemist describes itself by its customer:

A011Alchemist·Kind

“Alchemist | Silicon Valley Accelerator for Enterprise & B2B Startups”

Our reading: accelerator

Its flagship program page (opens in a new tab), read on 2 October 2026, says what that means: "Alchemist supports AI-SaaS and deeptech companies that monetize from enterprises, regardless of business model. The definition of an "enterprise startup" is based on where the revenue comes from. It's not based on the offering." The same answer names who qualifies: "All product types, customer segments/sizes, and business models are welcome (hardware or software, Fortune 500 or SMB, license/SaaS/freemium)."

So a SaaS product sold to small businesses counts, and a consumer app doesn't, however it is priced. Alchemist charges tuition, offset by its investment, and asks for a small stake (quoted); its higher bar for solo founders is quoted in accelerators for solo founders. Alchemist on the list.

06Dreamit: security and compliance software with traction

Dreamit is the narrowest of them. Its FAQ (opens in a new tab), read on 2 October 2026: "Dreamit invests in pre-Series A companies that have deployed a product and demonstrated early market traction in cybersecurity, anti-fraud, risk and compliance, and physical security. We like to see evidence of early product-market fit in the form of revenue, pilots, or design partnerships."

If you sell security or compliance software to companies and have pilots or revenue, read it first. If not, it isn't for you. Its check is the largest in the table, and its weekly partner meetings run over video (remote accelerators). Dreamit on the list.

07Which one fits your stage

They ask for different things before you apply. In their own terms:

• An MVP, little money raised: Forum Ventures (an MVP in market or about to be, under $500k raised).
• Revenue: TinySeed (it names a couple thousand dollars a month as a good sign) and Dreamit (revenue, pilots or design partners).
• Enterprise customers: Alchemist (revenue from businesses, of any size).
• B2B, not B2C: Startup Wise Guys.
• A security, fraud or compliance product: Dreamit.

Only TinySeed's wording leaves room for a consumer product, and only as a SaaS business. For a consumer app, the general programs are the place to look.

08Other programs SaaS founders apply to

Y Combinator and Techstars state no SaaS focus in the facts we hold, so a SaaS company applies to them like any other. Their deals are compared in YC vs Techstars vs a16z speedrun, and programs with checks in the same range are in Techstars alternatives and Y Combinator alternatives.

One more program says B2B in its tagline: UnternehmerTUM calls itself a deep tech B2B accelerator. Its focus line asks for "a strong deep-tech focus", so read its page before you apply with a typical SaaS product. It takes no equity and wants a full-time team (accelerators in Europe).

While you wait for a batch, credits from cloud and software companies can cut what you spend to build. The amounts and who qualifies are in startup credits programs. They are not investment.

09Launching is a different job

An accelerator funds and coaches the company. Getting a SaaS product in front of buyers runs on other sites: the directories and alternatives sites in SaaS directories, and the review sites in B2B software review sites. Add the programs you pick to My launch with the + on each poster:

10How we checked

Every quote comes from the program's own pages, with the exact words, as we read them on 2 October 2026. What we did: we read each place's own pages and checked its link; every table row and poster shows the date of our last link check. We picked programs by what they say about their own focus, not by their portfolios, and we don't know acceptance rates or results. Terms and calendars change between batches, so read the current page before you apply. This is not legal or investment advice.

Nobody pays to be listed or to appear in a guide. Read how we check for the details.
