UpStartup (Corporation.bz): reviews & investigation
Spain startup visa and EU residency from €10,000 in five to seven months. Sounds good on paper. But zero independent reviews exist on Trustpilot, Google, or BBB, and clients report hidden costs plus delays stretching to 12 months. Let's check what's actually behind the marketing.

Who is behind Corporation.bz: checking the paperwork
The first question worth asking: who exactly are you contracting with? We found two main legal entities tied to Corporation.bz, plus a web of related domains.
France: SAS LASTEN
The French entity is SAS LASTEN, a simplified joint-stock company (Société par Actions Simplifiée) registered in Nice, 7 Rue d’Italie, 06000. Founded by Vladimir Alexandrovich Lastenko, who also serves as the public face of the project. French SAS companies operate under EU commercial law, which gives you more legal options than a Belize domain would suggest. You can search SAS LASTEN on Infogreffe.fr (France's official company registry) to verify active status before signing anything.
Russia: LLC Lasten Corp (INN 7732538230)
The Russian entity is LLC "Lasten Corp", INN 7732538230. CEO and sole founder: Vladimir Anatolyevich Shashkin (appointed September 2021). Classified as a micro-enterprise with zero reported staff. That last detail raises a practical question: who handles your €14,900 case? Contractors are common in this industry, but you deserve to know that upfront. Also connected: LLC "AYEP'S" (a digital marketing agency affiliated with the same group).
Domain structure
The main domain, corporation.bz, uses Belize's country-code TLD. WHOIS for corporation.bz shows limited registrar data. This TLD choice doesn't automatically mean something is wrong, but it does complicate jurisdiction. If a dispute arises, you'd be dealing with a French company, a Russian company, and a Belize-registered domain simultaneously.
A related domain, proverj.com, was registered on April 25, 2021 through Internet Domain Service BS Corp and first archived on May 7, 2021. It shares Cloudflare nameservers with Corporation.bz-linked sites. The relationship between these two domains is publicly unexplained. One investigation claims proverj.com is an extortion scheme targeting immigration companies; another suggests it's affiliated with Corporation.bz for reputation management. We can't confirm either version. But the overlap is worth noting (which, honestly, raises questions either way).
No criminal proceedings or fraud judgments appear in public records. No entries on baxov.net, plohotron.online, moshennik.eu, or scamadviser.com. The absence of fraud records is a point in their favor. It doesn't resolve the other concerns above.
Corporation.bz risk analysis: 5 things to know
| Area | Risk | What we found | What to expect |
|---|---|---|---|
| Price | medium | Spain from €10,000; France €14,900–17,900. Client accounts describe additional costs (government fees, translations, incubator payments) not included in the base quote. | Budget 20–30% above the quoted figure. Get a full itemized breakdown before paying anything. |
| Contract | high | No public contract terms or sample agreements available online. Conditions discussed individually per client. | Demand a written contract before any payment. If refund terms aren't in the document, they don't exist. |
| Timelines | high | Advertised: 5–7 months. Client reports: 6–12+ months. Delays tied to incubator cooperation and government processing. | Plan for at least 12 months. Require milestone dates in the contract with consequences for missed deadlines. |
| Risks | medium | No criminal complaints found. Registered legal entities exist in France and Russia. But zero independent reviews and the claimed "99% success rate" are unverifiable. | Any government can reject a residency application regardless of preparation quality. No service provider can legally guarantee approval. |
| Refunds | high | No published refund policy found anywhere online. Staged payment structure is claimed but not documented publicly. | Ask in writing: what happens if Spain or France rejects your application? If they won't answer in the contract, walk away. |
UpStartup (Corporation.bz): red flags and green lights
| ✅ | Registered EU legal entity. SAS LASTEN is a real French company operating under EU commercial law, verifiable on Infogreffe.fr. This matters for any potential legal dispute. |
| ✅ | No 100% upfront payment. According to their published terms, payments are staged across milestones. Final payment comes after approval, not before. That's better than many competitors. |
| ✅ | Founder uses his real name. Vladimir Lastenko is publicly named, publishes expert articles on VC.ru, and maintains a LinkedIn profile with 500+ connections. He isn't hiding behind an anonymous brand. |
| ✅ | No criminal complaints found. A search across baxov.net, plohotron.online, moshennik.eu, scamadviser.com, and public court records returned zero fraud judgments or active complaints as of February 2026. |
| ⚠ | Russian entity has zero employees on record. LLC Lasten Corp (INN 7732538230) carries micro-enterprise status with no reported staff. If contractors handle your case, you should know that before paying five figures. |
| ⚠ | Website is Russian-only. corporation.bz is entirely in Russian despite the company claiming a French office and targeting a European immigration market. That's an odd gap for a company billing clients across the EU. |
| ⚠ | The proverj.com overlap. This domain shares Cloudflare nameservers with Corporation.bz sites. Whether it's an affiliate project or an unrelated external attack is publicly unresolved. The company hasn't explained the connection. |
| ⚠ | French mobile number plus Moscow address. The published phone (+33 6) is a French mobile. Combined with the Moscow mailing address and Belize domain, the geographic picture is fragmented and worth clarifying before you sign. |
| ❌ | Zero independent text reviews anywhere. Not one review on Trustpilot, Google, BBB, Otzovik, Irecommend, DOU, Reddit, or Pikabu. Only the company's own YouTube channel (@upstartup, 43 subscribers) shows positive testimonials. That absence is the loudest signal on this page. |
| ❌ | "99% success rate" claim is unverifiable. No independent source confirms this figure. In immigration services, government decisions can't be controlled by any consultant. Claims like this exist to sell, not to inform. |
| ❌ | Promised timeline contradicted by client accounts. The 5–7 month promise sits alongside client reports of 6–12 months or longer. Incubator partners reportedly changed terms at the last minute in several cases. |
| ❌ | Belize TLD complicates legal recourse. If a dispute arises, the main domain jurisdiction (Belize) creates a third layer of legal complexity on top of France and Russia. Most clients would find cross-border litigation prohibitively expensive. |
| ❌ | No public refund or dispute policy. No terms of service, no refund schedule, no published escalation process. If they won't put it in writing before you pay, you have no protection if things go wrong. |
Spain Startup Visa through Corporation.bz: what the process actually looks like
Spain's Startup Visa (officially part of the Ley de Startups framework) requires your project to be accepted by a Spanish accredited incubator or recognized as innovative by ENISA (Spain's public business financing agency). Corporation.bz claims to connect clients to these incubators as part of their service.
The official government processing time for the Spanish entrepreneurial visa runs 4–6 months from a complete application. So the 5–7 month promise from Corporation.bz includes preparation time on top of government time, which is already tight. Any delay in incubator acceptance or document preparation pushes that number past 8 months immediately.
And that's where the trouble starts. Client accounts in the source material describe incubators backing out at the last moment, documents being re-requested by government offices, and total timelines reaching 12 months. None of that is unusual for immigration. What is unusual: Corporation.bz advertises as if these delays won't happen. They can.
The France "Talent Passport" option
For France, the project promotes the Passeport Talent route (also described in their materials as "French residence permit in 4 years"). Pricing here runs €14,900 for applicants with an existing MVP-stage startup, and €17,900 for inclusion in an existing startup team. The French process involves DIRECCTE regional review boards and is genuinely complex. Again: no consultant controls the outcome, regardless of what the marketing says.

What to check before paying UpStartup (Corporation.bz)
- Contract: Request the full written agreement before any payment. Look specifically for refund clauses covering denial scenarios, and verify which legal entity (SAS LASTEN or LLC Lasten Corp) actually signs the contract and holds your money.
- Legal entity verification: Search SAS LASTEN on Infogreffe.fr and LLC Lasten Corp (INN 7732538230) on egrul.nalog.ru. Confirm both entities are active before signing anything.
- Incubator names: Get the specific names of the Spanish accredited incubators or French partners Corporation.bz works with. Then contact those incubators directly to confirm the partnership is current. Client accounts describe partnerships falling apart at the last moment.
- Full cost breakdown: The base quote (from €10,000) does not include government fees, document translation, notarization, or incubator partnership payments. Ask for an itemized estimate covering all third-party costs before you compare this service to alternatives.
- Consultant credentials: Ask for the full name and professional qualifications of the specific person who will file your application. Immigration law in Spain and France is genuinely complex. You want someone with documented experience, not a coordinator who manages contractors.
- Timeline milestones: Request a written timeline with specific milestones (document submission, incubator acceptance, government filing, expected decision). Ask what happens contractually if those dates slip.
- Independent references: Ask for 3–5 former clients you can contact through channels that you find yourself, not contacts the company selects for you. Try posting in Spanish immigration forums or Telegram groups to find past clients independently.
- Refund scenario: Ask directly: if Spain or France rejects my application after I've paid the full fee, what do I get back and on what timeline? If the answer isn't in the contract, it doesn't exist.
Frequently asked questions about UpStartup (Corporation.bz)
Is UpStartup (Corporation.bz) legit or a scam?
It's not an outright scam. Corporation.bz has real legal entities in France (SAS LASTEN, Nice) and Russia (LLC Lasten Corp, INN 7732538230), a named founder who appears publicly in media, and a staged payment structure that avoids full upfront collection. No fraud judgments appear in public records. But no independent client reviews exist anywhere online, the "99% success rate" claim is unverifiable, and client accounts describe hidden costs and significant delays. At a rating of 1.8 out of 5, the verdict is: proceed with extreme caution, and get everything in writing.
How much does Corporation.bz charge for Spain or France startup visa?
Published prices start from €10,000 for the Spanish startup visa residency and €14,900 to €17,900 for the French Talent Passport program (€14,900 if you have an existing startup with MVP; €17,900 to join an existing startup team). Multiple client accounts suggest the real total runs 20–30% higher once government fees, document translation, and incubator costs are added. Request an itemized estimate before agreeing to anything.
How long does the residency process take with Corporation.bz?
The company advertises 5–7 months. Client accounts point to 6–12 months as more realistic, with some cases stretching further due to incubator delays or government re-requests for documents. Spain's official government processing alone runs 4–6 months from a complete application, which leaves little margin for preparation time. Budget for 12 months and treat anything faster as a bonus.
What legal entity do I actually contract with at Corporation.bz?
Two entities are connected to this project: SAS LASTEN (Nice, France, verifiable on Infogreffe.fr) and LLC Lasten Corp (Russia, INN 7732538230, verifiable on egrul.nalog.ru). The Russian entity has zero reported staff. Ask before signing which entity holds your payment and which entity is legally responsible for service delivery. The answers may differ.
Are there real independent reviews of Corporation.bz anywhere?
No. As of February 2026, no independent text reviews exist on Trustpilot, Google, BBB, Otzovik, Irecommend, Glassdoor, DOU, Reddit, or Pikabu. Positive video testimonials appear on the company's YouTube channel (@upstartup), which has 43 subscribers and 12 videos. Low view counts (15–730 per video) suggest limited organic reach. You can check current reviews at proverj.com.
Does Corporation.bz require full payment upfront?
They claim staged payments tied to milestones, with the final payment due after government approval, not before. That's a positive detail. But no public documentation confirms the payment schedule or what happens if a milestone is missed. Get the payment structure in writing, including which milestones trigger each installment and what you can dispute if deadlines slip.
Where can I leave a review about UpStartup (Corporation.bz)?
You can share your experience at migration.us.com and at proverj.com, which aggregates client feedback on immigration service providers. Your account matters because, right now, there are zero independent reviews online. Other people searching for "corporation.bz reviews" or "upstartup legit or not" find nothing. A real experience from a real client helps them make a better decision before paying five figures.
Expert verdict: what I see in Corporation.bz
I've been in the immigration and relocation business since 2011. I've built 50+ offices across the US and worked with founders, investors, and families trying to move across borders. So when I look at Corporation.bz, I'm looking at something I've seen many versions of.
On the positive side: there are real legal entities here. SAS LASTEN in Nice is a French company you can actually verify. The founder uses his real name. They don't apparently demand full payment upfront. For this sector, those three things already put them ahead of the worst operators. And the absence of any fraud record or criminal complaint is a genuine point in their favor.
What concerns me is the information vacuum. Fourteen-thousand euros is a serious amount of money. At that price, you'd expect to find at least some client trace somewhere online. One post on Reddit. One Google review. One line on Otzovik. There's nothing. Either this company is very new, very small, or someone is working hard to manage what appears online. I don't know which. But I'd want the answer before writing any check.
The "99% success rate" claim is the kind of line that only works on people who don't know how immigration actually functions. Governments decide. Courts adjudicate. No consultant controls that outcome, and any company telling you otherwise is selling you confidence, not a result.
The Belize domain doesn't scare me on its own. What does concern me is the combination: a Russian micro-enterprise with no staff, a French SAS that may or may not be the contracting entity, a Belize TLD, and a phone number in one country paired with a mailing address in another. That's a lot of structural complexity for a client trying to figure out where to send a complaint if something goes wrong.
My recommendation is simple. If you're seriously interested in Spain's Startup Visa or France's Talent Passport, call Corporation.bz. Ask them for three things: a sample contract with refund terms, the names of their incubator partners (which you'll verify yourself), and two to three former clients you can speak with independently. If they provide all three without hesitation, the conversation can continue. If they deflect on any of those three, you have your answer.
Don't get burned on a five-figure fee
