Frequently Asked Questions
What do private equity firms look for in companies?
PE firms look for companies with strong cash flows, experienced management teams, clear growth opportunities, and the potential to increase value through operational improvements. They typically seek 3-5x returns over a 3-7 year holding period.
How is private equity different from venture capital?
VCs invest in early-stage, high-growth companies in exchange for equity. PE firms typically invest in more mature companies through buyouts or growth equity, focusing on cash flow and operational improvements. PE deals are usually larger and involve more debt financing.
What's the typical size of a lower mid-market PE deal?
Lower mid-market PE firms typically invest $10M-$100M in companies with $5M-$50M in EBITDA. These firms often focus on specific industries or geographic regions.
Should I prepare my company before approaching PE firms?
Absolutely. PE firms due diligence thoroughly. Having clean financials, strong management, documented processes, and clear growth plans significantly increases your attractiveness and valuation.
What happens after a PE firm invests?
PE firms typically take an active role in the company, often adding board members, helping recruit executives, and implementing operational improvements. They exit through sale to strategic buyers, other PE firms, or IPOs.
How long does the PE fundraising process take?
The process typically takes 6-12 months from initial outreach to closing. This includes preliminary discussions, formal due diligence (3-4 months), legal documentation, and final closing.
