Startup accelerators in Spain trade training, a network and sometimes cash for equity, a right to invest later, or nothing at all.
Lanzadera runs 6–12 month programmes and its sister company Angels invests in alumni; Decelera invests up to €300,000; BStartup up to €200,000; SeedRocket takes no equity. Check the instrument and the implied valuation before signing.
Below: how an accelerator differs from an incubator in Spain, which programmes are active in 2026 and on what terms, what a programme really costs you in equity, which instruments other than shares turn up in Spanish contracts, the red flags founders should walk away from, and how to prepare an application.
Spanish venture funds and angel networks are covered in Venture capital and business angels in Spain, and ENISA loans, CDTI Neotec grants and the startup law in Support programs for startups in Spain. This article is about the programmes in between.
Accelerator or incubator: what is the difference in Spain
The two words are used loosely, and many Spanish organisations run both. The useful distinction is the stage of the company and what the programme expects from it.
| Incubator | Accelerator | |
|---|---|---|
| Stage | Idea, prototype, pre-seed; sometimes before the company is incorporated | Product on the market or an MVP with real customers; seed |
| What it gives | Training, mentors, a desk in a coworking space, introductions to the local ecosystem | A structured programme, a demo day with investors, corporate contacts, sometimes an investment |
| Money | Usually none, or small prizes at the final | From zero to a few hundred thousand euros, through equity or another instrument |
| Who runs it | City and regional agencies, chambers of commerce, universities, associations | Private companies, corporates, banks, venture funds |
| What it costs | Usually free; time | Equity, a warrant or a right to invest; a lot of time |
The goal of an incubator is to take a project from an idea to the first validated version; the goal of an accelerator is to get it ready for a seed round.
In practice, founders who skip the incubator stage often reach an accelerator with a weak application: no clear metrics, no documents, no answer to “why now”.
The stages themselves are described in Startup stages from idea to IPO.
A typical public incubation programme looks like this: the Cybersecurity Startup Program run by INCIBE, the national cybersecurity institute, and Startup Valencia has an incubation track and an acceleration track with training, expert mentoring, networking and company visits, a demo day in front of investors and potential customers, and prizes of €5,000 for the winner of the incubation track and €10,000 for the winner of the acceleration track.
No equity, no investment: the value is the network and the access to the region’s ecosystem.
Startup accelerators in Spain: programmes and terms in 2026
The table lists programmes whose terms we checked on their official websites on 9 November 2026. It is not a ranking: each programme has its own stage, sector and logic.
Terms change from one call to the next, so read the current call before applying.
| Programme | Where | Stage | Money | What you give | Length and format |
|---|---|---|---|---|---|
| Lanzadera | Valencia, Marina de Empresas | Revenue, or an MVP launched with real customers | Investment comes from Angels, a sister company within Marina de Empresas | Equity only if Angels invests | 6 months, extendable to 12; founders full time and on site at least 3 days a week |
| Decelera | Menorca; fund in Madrid | Pre-seed and seed, Southern Europe | Up to €300,000 before the programme, up to €1 million cumulative after it, follow-on up to €2 million | No fee or equity to attend, but you grant Decelera an investment right | 7 days, up to 15 companies; next programme May 2027 |
| BStartup (Banco Sabadell) | Madrid, Barcelona hubs | Seed; mostly B2B, software, AI, deep tech | Tickets up to €200,000, follow-on up to €2 million | Equity | Evergreen vehicle owned by the bank; separate Health and Green lines |
| Mission (formerly Demium) | Madrid | Pre-seed; invests in founders, with or without a team or a defined idea | “From €100,000” | Equity; terms not published | Rebranded in January 2026 with a €35 million pre-seed fund |
| Wayra (Telefónica) | Spain, Germany, UK, Brazil | Seed and growth | Not published | Equity | Corporate venture capital: invests in startups that can do business with Telefónica and introduces them to its business units as a customer |
| SeedRocket | Madrid, Barcelona | Early-stage technology startups | None directly: it connects startups with its investor club and network | No equity | Entry through the Campus de Emprendedores (the 36th in Madrid, 16–20 November 2026), Investors’ Days or mentor referral |
| Cybersecurity Startup Program (INCIBE and Startup Valencia) | Valencia | Incubation and acceleration tracks; any sector with cybersecurity in the value chain | Prizes €5,000 and €10,000 | Nothing | Programme with demo day; the last call closed on 11 January 2026 |
Two more names come up in every list.
Startup Valencia is a private non-profit association founded in 2017 that connects more than 3,000 startups and scale-ups; it does not invest, but its programmes, events and perks are an entry point to the Valencian ecosystem.
City agencies such as Barcelona Activa and Madrid Emprende run public incubators: they are covered in Support programs for startups in Spain.
The table shows the main point: “accelerator” in Spain covers very different deals.
Lanzadera is a training programme with an investor next door; Decelera and BStartup are venture funds with a programme attached; SeedRocket is a connector that takes no equity; Wayra invests when the startup is useful to Telefónica.
What an accelerator gives you beyond money
- A method and a deadline. A programme forces the team to set targets, measure them weekly and report to a mentor. Lanzadera assigns each startup a project director with weekly sessions and builds the programme around its “Total Quality Model”, the management framework of Mercadona. In practice, founders say the discipline matters as much as the content.
- The network. The Spanish ecosystem is small: investors, corporates and programme managers know each other. A good programme opens doors to angels, funds and large companies; a reputation for misleading anyone in due diligence closes them just as fast.
- The demo day. Investors come to the final presentations to see the whole cohort at once. Founders’ experience: a strong cohort attracts investors who then follow its best startups for months.
- Corporate pilots. Corporate programmes such as Wayra are built around a first large customer. That is worth more than a small cheque, but a buyer of the company later may be wary of a competitor on the cap table.
- Perks. Programmes negotiate credits and discounts with cloud and software providers. AWS Activate gives self-funded startups up to $5,000 in credits, while the Portfolio tier gives pre-Series B startups up to $200,000 through an Organization ID from an Activate provider such as an accelerator, angel investor or venture fund. For a software startup, a year of free infrastructure is real money.
What it costs you: equity, valuation and dilution
An accelerator that invests cash for a share of the company is pricing your startup.
The implied valuation is simple: post-money valuation = investment ÷ share; pre-money = post-money − investment.
The numbers below are an illustration calculated for this article, not the terms of any specific programme.
| Offer | Post-money valuation | Pre-money valuation | Founders after the programme | Founders after a seed round of €1m at €4m pre-money | Programme’s stake valued at the seed price |
|---|---|---|---|---|---|
| No accelerator | — | — | 100% | 80.0% | — |
| €50,000 for 6% | €833,333 | €783,333 | 94% | 75.2% | 4.8% = €240,000 |
| €100,000 for 20% | €500,000 | €400,000 | 80% | 64.0% | 16.0% = €800,000 |
| 6% for training only, no cash | — | — | 94% | 75.2% | 4.8% = €240,000 |
What this means at seed:
- €50,000 for 6% values the company at €783,333 before the money. If six months later a fund invests €1 million at €4 million pre-money, the accelerator’s stake is worth €240,000 at the new price: the programme paid €50,000 for it. That is the normal price of early risk, but compare it with the value of what the programme actually gives.
- €100,000 for 20% is a €400,000 pre-money valuation. After one seed round the founders hold 64% instead of 80%. With a Series A and an option pool still to come, founders can lose control before the company is mature, and later investors notice a cap table where an early programme holds a large block.
- Equity without cash is the most expensive line. 6% for training and introductions costs the same equity as 6% for €50,000. Founders who have been through several programmes give the same advice: do not give equity at pre-seed for mentoring alone.
- At exit the difference is large. With a sale at €20 million after the seed round, 6% before seed is worth €960,000 to the programme and 20% is worth €3.2 million.
How each round changes ownership, and how option pools and convertible instruments enter the calculation, is shown in Cap table and dilution.
To argue about the valuation rather than accept it, build the forecast first: a financial model with the use of funds shows what the programme’s money buys and what the next round should look like.
Not only equity: warrants, investment rights and participating loans
Many founders expect “money for shares”. Spanish and international programmes use a wider range of instruments, and the contract matters more than the headline.
- Warrant on future equity. The Founder Institute asks founders, about two-thirds of the way through its programme, to pledge 2.5% of future equity to its Equity Collective as a warrant; it activates only at a qualified equity financing of $100,000 or more from outside investors and carries no board seat or voting rights. The programme also charges an entrance fee, $1,099 for the Silicon Valley cohort. The terms are public, which is good; the point is that a warrant is still equity and dilutes the founders when the round comes.
- Investment right. Decelera charges no fee and takes no equity to attend, but participation requires granting it an investment right, and a startup that does not want the investment cannot attend. Read what the right covers: the amount, the price or discount, and for how many rounds.
- Participating loan. A common Spanish instrument, used among others by ENISA. Under article 20 of Royal Decree-law 7/1996, the lender receives variable interest linked to the company’s results; in insolvency the loan ranks after ordinary creditors; and it counts as equity for capital reduction and liquidation purposes. It is debt: it has to be repaid, even though it supports the balance sheet.
- Convertible notes. A loan that converts into shares at the next round, usually with a discount or a valuation cap. Spanish SLs use them in early rounds; how they convert is in Cap table and dilution.
Founders’ experience: a contract can combine a stake with a loan, so the company ends up owing both equity and money.
Before signing, ask the programme to state in one line what you give, what you owe, and when.
The investor agreement is where those terms are fixed, together with information rights, a board seat and consent rights.
Red flags before you sign
- Equity for training. A stake for lectures, mentors and a desk, with no cash and no investor network that you can check.
- An instrument you cannot explain. Equity plus a loan, a revenue share or an open-ended investment right without a price, an amount or a deadline.
- A fee plus equity without a list of alumni who raised a round after the programme.
- No alumni you can call. A serious programme gives you its portfolio; talk to two or three founders from previous cohorts who are not on the programme’s showcase.
- Rights that block the next round: pre-emption on all future rounds, a veto over the choice of investors, a board seat for a small stake.
- Time you do not have. Lanzadera expects founders working full time and on site at least three days a week. A programme that takes the CEO away from sales for six months has a cost that does not show in the term sheet.
- Promises of grants for a success fee. In practice, advisers attached to programmes offer to file grant applications for a percentage. Check what the fee covers and whether you can choose another adviser.
How to get into an accelerator in Spain
- Match the stage. Read the requirements before writing the application. Lanzadera admits founders who already have revenue or an MVP launched with real customers, and only one project per call; the current call accepts applications until 14 December for a start on 8 March. Applying too early wastes a call.
- Treat applications as a funnel. Decelera describes selecting 12 founders out of 3,600 applications. Founders who raise apply to many programmes at once, with one strong master application adapted for each.
- Prepare the numbers. A short deck, metrics with history, the round you plan, the use of funds and a cap table. Programmes that invest run due diligence; Decelera invests only after due diligence of both the technology and the founders. A clear business plan with a forecast answers most of the questions in advance.
- Keep the books clean. Losses in the first year are normal for a startup, but Spanish rules look at equity. ENISA requires own funds at least equal to the loan requested, and losses that reduce net equity below half of the share capital are a legal ground for dissolving an SL unless the capital is increased or reduced (art. 363.1.e of the Capital Companies Act). Founders’ experience: an investor or a lender who sees negative equity in the filed accounts stops at that line. Plan capital contributions before the accounts are filed, not after.
- Be ready for the interview. Selection committees test whether the founder’s answers about the team, market, product and money are consistent with each other. Rehearse a three-minute and a five-minute pitch and the questions on unit economics.
- Read the contract with an adviser. Calculate the implied valuation, the dilution after the next round and the obligations that survive the programme.
Accelerators are one route among several.
Public money (ENISA participating loans of €25,000 to €1,500,000 with no collateral and no equity, CDTI Neotec grants) and angels often come in the same year.
How the pieces fit is described in Support programs for startups in Spain; the way to venture funds after the programme in Venture capital and business angels in Spain.

Frequently asked questions
What is the best startup accelerator in Spain?
There is no single best one: the right programme depends on stage and goal. Lanzadera in Valencia is known for a long, intensive programme and its sister investor Angels; Decelera and BStartup are funds that invest up to €300,000 and €200,000; SeedRocket takes no equity and connects startups with investors.
How much equity do accelerators take?
It depends on the deal: some take none, some take a stake for cash, some take a warrant or a right to invest later. Calculate the implied valuation: €50,000 for 6% means €833,333 post-money. Equity for training alone, without cash, is the most expensive option.
What is the difference between an accelerator and an incubator?
An incubator works with an idea or prototype and gives training, mentors and space, usually without money. An accelerator works with a product on the market or an MVP with customers, ends with a demo day for investors and sometimes invests in exchange for equity or another instrument.
Do startup accelerators in Spain give funding?
Some do. Decelera invests up to €300,000 before its programme, BStartup tickets go up to €200,000, Mission (formerly Demium) invests from €100,000. At Lanzadera, investment comes from its sister company Angels. SeedRocket and public incubators do not invest directly.
How do startup accelerators make money?
Mostly from the equity they receive: a stake, a warrant or a right to invest that pays off when the startup raises or is sold. Some charge fees, and corporate programmes such as Wayra gain new suppliers and technology for the parent company.
Can a foreign founder join a Spanish accelerator?
Yes, most programmes accept founders from any country, but many expect the company to operate in Spain and the team to be present. Lanzadera, for example, asks founders to be on site at least three days a week.
When should a startup apply to an accelerator?
When it meets the programme’s stage requirements and has time for it. Lanzadera asks for revenue or an MVP with real customers; incubators accept ideas. Apply as soon as a call opens and prepare the deck, metrics and accounts in advance.
