Lead
Capitolis, the Israeli-founded, New York-linked fintech valued at $1.6 billion in 2022, has agreed to acquire Boston-based eSecLending for $200 million in an all-cash transaction. The company announced the deal on September 29, 2026. The sellers are private equity firm Parthenon Capital and eSecLending's management team.
The structure has a twist. Parthenon, which is cashing out of eSecLending, will reinvest in Capitolis as part of the same transaction. The size of that investment and any change to Capitolis' valuation were not disclosed.
What Is eSecLending and What Does It Do?
eSecLending is an independent securities lending agent founded in 2000, with a 26-year history in securities financing. It works with pension funds, insurance companies, asset managers and other institutional asset owners, helping them lend securities to major global banks and prime brokers. It also offers auction-based lending, customized programs and collateral management.
The business employs about 120 people. Its revenue and profit were not disclosed. One piece stays outside the deal: eSecLending (Europe) Limited is excluded from the transaction, though it will continue to provide services to the business.
Why Did Capitolis Pay $200 Million?
Capitolis bought access to a client group it has not historically served: the largest asset owners. Its platform has so far been built around banks, which use it to compress trades, free up balance sheet and optimize capital. Securities lending puts Capitolis in front of the other side of the market, the institutions that hold the securities banks want to borrow.
Capitolis CEO and founder Gil Mandelzis called the deal "a transformational acquisition" and said eSecLending "adds a highly complementary new business." Capitolis President Okan Pekin said combining the two companies "expands our network and enhances our offering." The company describes the pairing as a broader financial resource optimization offer spanning securities lending, repo and financing markets.
The deal also changes the business mix. Capitolis has been a software and network company; eSecLending is a services business with fee income tied to lending programs. Its 120 employees would add to a Capitolis workforce of roughly 200, so the acquired team would be a large share of the combined headcount.
How Does This Fit Capitolis' Acquisition Record?
The eSecLending purchase is Capitolis' fourth strategic acquisition in five years, and the company says it has continued to grow organically over the same period. Its earlier purchase of Capitalab was priced at $46 million, which makes eSecLending more than four times larger than that deal.
Capitolis was founded in 2017. Its last disclosed priced round was a $110 million Series D in March 2022, co-led by Canapi Ventures, 9Yards Capital and SVB Capital, at a $1.6 billion valuation. It has raised about $300 million in total, including from banks such as Barclays, JPMorgan, BNP Paribas, Citi, Morgan Stanley, State Street and UBS. A $200 million cash outlay is a large share of that total, which suggests the purchase draws on cash flow from operations, the Parthenon reinvestment, or both. Neither the funding source nor the new valuation has been disclosed.
What Does the Parthenon Reinvestment Signal?
The sellers are taking part of the exit back as a stake in the buyer. Private equity owners typically do this when they want continued exposure to a combined business they expect to be worth more than the standalone asset. It also ties the seller's interest to the integration succeeding.
For Capitolis, an institutional private equity backer adds a shareholder with experience in financial services assets. It also leaves open a question on valuation. The 2022 mark of $1.6 billion came near the top of the fintech funding cycle, and a fresh investment would reveal where Capitolis now stands.
What Comes Next?
The transaction is subject to customary closing conditions, including regulatory approvals and antitrust clearance. No closing date has been announced. FT Partners and WilmerHale advised Capitolis. Berenson & Company and Raymond James advised eSecLending on the financial side, with Troutman Pepper Locke and Debevoise & Plimpton as legal counsel.
The main execution risk is integration. eSecLending's clients are asset owners with their own governance and procurement processes, and they differ from the bank clients that built Capitolis' network. Capitolis has to keep those clients while cross-selling its bank-side tools, and the sale of a service-heavy business to a software company can unsettle client relationships.
If the integration works, Capitolis will sit between banks and the asset owners that supply them with securities. That position would make its network more difficult to replicate.
Outlook
Capitolis has used its fourth acquisition to move from bank-side balance sheet tools into securities lending, backed by a $200 million cash payment and a Parthenon reinvestment of undisclosed size. Closing depends on regulatory and antitrust clearance, and the outstanding questions are the Parthenon stake, the funding source and the implied valuation. The measure of the deal will be whether eSecLending's asset-owner clients stay and whether banks and asset owners start using a single combined platform.
