Capital For What’s Next

Turn/River provides capital uniquely tailored to help bootstrapped, growing, technology companies and their founders achieve their goals.

About Us

We started Turn/River because we see the emergence of new type of web company — one that is lean from the start — operating profitably at small scale by taking extreme advantage of the web for distribution, outsourcing and iterative learning. But, we know that these companies are, in a strange way, a tough fit for the existing financial players: too capital efficient for venture capital, too small for private equity and too messy for strategics. Turn/River was built specifically to step into this gap.


Turn/River specializes in growth capital investments, founder liquidity, buyouts, spin-outs, recapitalizations of small-scale technology, web and Saas companies. Our strategy is to combine rigorous, iterative marketing, sales and operational execution with capital to help companies double or triple their growth, and build value for everyone.
