Keystone Business Advisors is a mergers and acquisitions advisory firm based in Westlake Village, California, focused on helping owners of privately held companies sell their businesses.
They operate in a specific segment of the M&A market that many competitors skip over entirely: companies with annual revenues between $5 million and $100 million.
For business owners in Southern California who are thinking about selling, the firm has built a track record of over 250 completed transactions and a self-reported closing rate that significantly outpaces the industry average.
Key Takeaways
- Keystone Business Advisors is a legitimate, established M&A firm with over 250 completed transactions.
- They charge no upfront fees, earning their commission only after a transaction closes.
- Their focus is on lower middle-market California businesses with revenues between $5 million and $100 million.
Who Is Keystone Business Advisors?
Keystone Business Advisors was founded and is led by Managing Partner Dave Richards, who holds the M&AMI (Mergers & Acquisitions Master Intermediary) and CBI (Certified Business Intermediary) designations, along with an MBA.
The firm is headquartered at 250 N. Westlake Boulevard, Suite 230, in Westlake Village, CA 91362. Their team currently includes four advisors: Dave Richards, Greg Martin, Derek Branch, and Darryl Heller.
The firm is a member of several industry organizations, including:
- IBBA (International Business Brokers Association)
- M&A Source
- CABB (California Association of Business Brokers)
- Cornerstone International Alliance
- ProVisors
Membership in these organizations is a meaningful credibility signal. The IBBA and M&A Source, in particular, require members to follow professional standards and codes of ethics.
The CBI designation from IBBA and the M&AMI from M&A Source both require demonstrated transactional experience and ongoing education.
What Does Keystone Business Advisors Do?
Keystone provides sell-side M&A advisory services to owners of California-based businesses. Their core service involves managing the entire sale process from start to finish. Here's a breakdown of what they handle:
| Service | What It Covers |
|---|---|
| Business Valuation | Market-based analysis using comparable sales data to determine probable selling price |
| Confidential Information Memorandum | 30 to 50-page document highlighting value drivers, financials, and competitive advantages |
| Buyer Marketing | Both broad and targeted outreach to strategic and private equity buyers |
| Buyer Screening | Financial and operational vetting before any confidential information is shared |
| NDA Management | Confidentiality agreements required before releasing sensitive data |
| Negotiation | Representation through the full negotiation process |
| Due Diligence Support | Upfront identification of potential deal-killers before they surface |
| Financing Referrals | Connections to SBA and conventional lenders |
| Business Consulting | Pre-sale advisory work, sometimes starting one to three years before listing |
They do not charge upfront retainers, which separates them from investment banks that typically require fees before any work begins. Keystone's fee structure is success-based, meaning they only get paid when a deal closes.
Who Is Keystone Best Suited For?
Keystone is specifically built for owners of privately held California businesses generating between $5 million and $100 million in annual revenue. That's the lower middle market, a segment that traditional main street business brokers tend to underserve (those brokers usually focus on restaurants, retail shops, and smaller service businesses), while investment banks often won't touch it because the deal sizes are too small to justify their minimum fee thresholds.
Industries they have experience in include:
- Manufacturing
- Wholesale and distribution
- Healthcare
- Ecommerce
- Technology
- Transportation and logistics
- Professional services
- Construction
- Landscape services
If a business owner is outside California or generating revenue below $5 million, Keystone is likely not the right fit. Their model is deliberately focused on this specific geography and deal size.
Keystone Business Advisors' Closing Rate
One of the more compelling statistics Keystone puts forward is their closing rate. The firm claims a rate of over 90%, compared to an industry figure of 20% to 30% for businesses that go to market and ultimately sell.
That is a significant gap, and it is worth understanding how they explain it. According to Keystone, the higher close rate comes from a combination of factors: a rigorous client selection process, limiting the number of active engagements at any given time so each deal gets adequate attention, and conducting extensive due diligence before a business is ever introduced to buyers.
The idea is to resolve potential deal-killers in advance rather than letting them surface mid-process.
These claims come from Keystone's own website, so prospective clients should weigh them accordingly. That said, the volume of detailed client testimonials on the site and the breadth of completed transactions listed do give some support to the narrative.
What Clients Say
The testimonials on Keystone's website are specific and attributed to named individuals and companies, which adds more credibility than anonymous reviews. A few examples:
Alan Sherry, Founder of Stellar Technical Products, described selling his 32-year-old company through Dave Richards. He highlighted Richards' ability to manage the emotional side of the process and understand the seller's personal goals alongside the business valuation.
Randy Serika and Helen Linden, owners of Perma Guard Security Systems, a 42-year-old company, noted that cultural fit with the buyer was a priority, and that Keystone invested significant time researching both the business and potential acquirers.
Jack Kerns, Founder of Hort Tech, Inc., said the process from start to finish took nine months and produced multiple qualified buyers to choose from.
Robert E. Gipson, a business and corporate finance attorney, credited Keystone with keeping a complex transaction moving forward despite financing complications.
The consistent theme across reviews is responsiveness, attention to detail, and the ability to keep deals alive when problems arise. No negative reviews are published on the company's own website, which is expected, but the specificity and attribution of the positive ones make them harder to dismiss outright.
Fee Structure
Keystone does not charge upfront retainers. Their compensation comes entirely from a success fee paid at close. This is a meaningful point: it aligns Keystone's incentives directly with the seller's goal of completing the transaction at the best possible price. If a deal doesn't close, Keystone doesn't get paid.
This contrasts with investment banks that charge monthly retainers regardless of outcome. For lower middle-market sellers, the Keystone model means less financial risk in getting started with the process.
The specific percentage of their success fee is not published on their website. Sellers would need to go through an initial consultation to get that information.
Limitations and Considerations
Keystone is geographically focused on California. Their model and marketing are tailored to Southern California, and the bulk of their completed transactions appear to involve California-based businesses. Sellers outside of this region would need to look elsewhere.
Their lower revenue threshold is $5 million in annual sales. Business owners with smaller companies are not the target client and would likely be better served by traditional business brokers.
Fee transparency is limited on their website. While the success-based structure is explained, the actual commission percentage requires a direct conversation. That is common in the M&A advisory industry but worth noting for anyone trying to compare options before making contact.
