Most founders sell to whoever shows up. We change that.
We run a global competitive process, drawing from a proprietary database of 300,000 financial and strategic investors worldwide, to make sure you are choosing between the best offers, not just the first ones. As a boutique firm, we take on a limited number of mandates each year. Every client works directly with Marcin and Filip from day one.
Every transaction is unique. We adapt to your strategic goals.
A successful exit requires aligning the deal structure with your long-term objectives. We tailor our approach to fit your specific scenario and market dynamics.
Strategic Exit & Full Cash-out
You have built a robust business and are ready to monetize your equity. We orchestrate a competitive auction process to secure a premium valuation and ensure a clean, absolute exit that protects your personal wealth.
Growth Capital & Private Equity
Your company requires significant capital and institutional know-how to scale internationally or execute acquisitions. We connect you with the right Private Equity funds, structuring deals that allow for partial cash-out while keeping you involved in the upside.
Corporate Divestitures & Carve-outs
Looking to spin off a non-core business unit or pivot to a new venture? We structure fast, efficient divestiture processes that free up your capital and internal resources without disrupting your core operations.
Inbound Offers & Valuation Defense
Received an unsolicited offer from a competitor or a global fund? Their team has done this dozens of times. You may be doing it once. We independently validate the offer, neutralize their negotiating leverage, and run a parallel process to ensure the number on the table is the right one.
300,000 investors in the database. We know which 30 are right for you.
The database is the foundation. The real work is filtering it down to the buyers who are actively deploying capital in your sector, at your deal size, right now, not six months ago. We map every acquirer by their stated investment thesis, recent transaction history, current portfolio gaps, and active acquisition mandates. The result is a targeted, prioritised longlist of buyers who have a genuine strategic or financial reason to want your company specifically.
Strategic Acquirers
Corporates and industry players who acquire to expand their product suite, enter new markets, or consolidate a fragmented sector. We identify the ones for whom your company fills a specific gap in their roadmap.
- Product and technology adjacency mapping
- Revenue and customer base synergies
- Geographic expansion logic
- Active M&A programme screening
Private Equity Funds
Financial sponsors seeking platform investments or add-ons within their existing portfolio. We filter by fund size, sector focus, current deployment cycle, and whether your profile fits a platform or bolt-on thesis.
- Fund vintage and deployment cycle analysis
- Existing portfolio fit assessment
- EBITDA and revenue threshold matching
- Growth equity vs buyout preference screening
How we go from 300,000 to your shortlist
Every mandate begins with a structured buyer mapping exercise. We don’t send your teaser to 300,000 people. We identify the 60–80 most relevant, approach them in a controlled sequence, and create genuine competitive tension between the strongest candidates.
The Aventis M&A Process: Built for speed, powered by AI, closed with conviction
Corporate acquirers have dedicated BD teams running processes continuously. You are doing this once. We close that gap with AI-driven research, automated outreach, and a negotiation approach built on reading people as much as modelling numbers. Your team stays focused on running the business. We handle everything else.
Valuation & Equity Story
We start with AI-assisted financial benchmarking: your EBITDA normalised, your metrics stress-tested against hundreds of comparable transactions in our database. The output is an Equity Story built not on hope, but on data. Buyers see a company positioned precisely where it commands the highest multiple.
Buyer Targeting, Teaser & NDA Execution
Our AI scans 300,000 investors to surface the 30 to 50 most relevant buyers for your specific profile, running in days rather than weeks. Through Globalscope, our alliance of independent advisors across 40+ countries, we run a parallel outreach campaign. Teasers go out anonymised. NDAs come back fast. The process moves.
Information Memorandum & Management Presentations
We produce the CIM at a speed most advisors cannot match: structured templates, AI-assisted drafting, and Marcin and Filip reviewing every word. Your management team is coached on how to present, how to answer hard questions, and how to read the room. Competitive tension is deliberately maintained throughout.
Offer Evaluation & LOI Negotiation
Marcin has sat across the table from hundreds of acquirers. He knows when an offer is genuinely competitive and when it is a test of your resolve. We read the motivations behind each bid, play parties against each other with discipline, and negotiate an LOI that holds. Price, structure, reps, exclusivity, all of it.
Due Diligence, SPA & Closing
Most value erosion happens here, after the LOI. We run the VDR with precision, respond to diligence queries fast, and stay in the room when legal negotiations get difficult. When buyers try to retrade, we push back. When momentum risks stalling, we accelerate it. We do not leave until the funds hit your account.
Discuss your transaction timeline
A structured M&A process typically takes 6 to 12 months to complete. The best outcomes, however, tend to start with preparation 12 to 24 months earlier. Let’s have a brief conversation to assess where you are and what, if anything, needs to be in place before you go to market.
Schedule a Discovery CallTrusted by companies navigating complex transitions
“For CKSource, the transaction was a major milestone. The Aventis Advisors team handled the entire M&A process seamlessly, allowing us to maintain our focus on scaling the core business. Thanks to their expertise and strategic approach, we secured a partnership with an excellent investor. I highly recommend them to any tech company considering an M&A transaction.”
What working with Aventis actually looks like
You speak directly with Marcin and Filip from the first call. There is no handoff to a junior team after the pitch. Our goal is not to close a deal. It is to make sure the right deal happens, with the right buyer, at the right time. Here is what that means in practice.
Marcin Majewski
Founder, Managing Partner
Filip Drazdou
M&A Director
“I started Aventis for the thrill of a deal. The complexity, the negotiations, the moment everything comes together. What I did not expect was how much I would come to care about everyone whose life the deal touches. The founders, and the teams whose futures change when ownership does. That is what keeps me here.”
Marcin Majewski, Founder
300,000 investors. Global. Always current.
We maintain a proprietary, continuously updated database of 300,000 financial and strategic investors across every major market. We don’t guess who might be interested in your company. We know, and we approach them systematically to generate genuine competitive tension.
AI-powered buyer identification
We use AI-assisted market mapping to identify acquirers most advisors wouldn’t think to contact: PE funds actively deploying capital in your niche, strategic buyers whose M&A thesis fits your specific profile. Data-driven outreach, not a static contact list.
A boutique that tells you the truth
We take on a limited number of mandates per year, by design. That means we can afford to be honest. If the market or your metrics don’t support your valuation target right now, we will tell you to wait. We do not believe in deals for their own sake. We believe in the right deal, with the right buyer, at the right time.
Success-based. Fully aligned.
Our fee has two components: a retainer that covers preparation and research costs, and a success fee tied to the final transaction value. The retainer is cost-recovery. The success fee is where we earn. We are not incentivised to close fast. We are incentivised to close well.
We advise the founder, not just the transaction
An exit is not only a financial event. It is a personal one. Before we model your EBITDA, we ask different questions.
What does life after the deal look like for you?
Are you staying on as CEO under new ownership, or making a clean exit? Your answer changes the deal structure, the buyer profile, and the negotiation strategy entirely.
What are your personal financial and tax constraints?
We think about deal structure, including earn-outs, rollover equity, and escrows, through the lens of your personal situation, not just the headline number. A higher valuation that creates tax inefficiencies is not always the best outcome.
Is now actually the right time to sell?
Most advisors are incentivised to say yes. We are not. If the market timing or your company’s metrics suggest waiting 12–18 months would materially improve your outcome, we will tell you that clearly.
What happens to your team and your legacy?
For many founders, the fate of the people they built the company with matters as much as the price. We factor that into buyer selection and negotiation, not as sentiment but as a real deal parameter.

We help software founders unlock full value and secure a strategic exit. Our proprietary SaaS valuation models factor in specific metrics—ARR, NRR, CAC, and Churn—that global strategic buyers and Private Equity firms use to justify premium multiples.
IT Services & MSPs
Selling an IT services firm presents unique challenges. Whether you specialize in custom software development, system integration, or managed services, we position your business based on utilization rates, client retention, and reliable delivery efficiency.
