Start-ups: In search of venture capital

To secure elusive funding, entrepreneurs must understand the financial landscape and the motivations of investing firms.

Somewhere between borrowing money from friends and family and maxing out their personal credit cards, many scientists and researchers trying to take their discoveries from the lab to the marketplace decide to seek the counsel and financial support of a venture-capital firm. Such firms have long had a key role in establishing legal structures and marketing strategies for start-up companies, as well as in providing them with the funding to stay afloat until they are robust enough to secure a commercial bank loan, be purchased by a larger competitor or achieve sales that signal long-term success.

Yet, like insurance-claims adjusters, venture-capital firms are often the kind of friends that scientists might not want. That doesn't mean that they aren't highly valued partners, but the relationship frequently starts out on an unequal and problematic footing. “It's not just about money, it's about chemistry,” says Ellen Rudnick, executive director of the Michael P. Polsky Center for Entrepreneurship at the University of Chicago in Illinois. “You want somebody there whom you trust and who really understands your business. You have to think of them as a marriage partner.”

Scientists can improve their odds of success in securing capital by knowing their options and responsibilities. The likelihood of achieving victory and avoiding pitfalls, such as surrendering one's fledgling company, increases if researchers know their goals from the outset, put a plan into motion to achieve them, recruit established hands to support their pursuit and go into the search with realistic expectations.

Devising a game plan

Firms aren't drawn to great ideas alone; they're attracted to great ideas that have the promise of financial success. It's a painful truth that many astonishing innovations won't ever win the favour of venture-capital firms, because they lack a market. “You need to ask yourself from a purely scientific standpoint: is this idea differentiated in the eyes of my peers? Is there something unique scientifically about my idea?” says Robert Nelsen, co-founder and managing director of ARCH Venture Partners in Seattle, Washington. “We're looking for the revolutionary rather than the evolutionary.”

For scientists working in universities or government labs, the vetting process starts with technology-transfer offices, which protect, manage and license research. Scientists who receive university or federal grants need to work out any potential licensing sticking points before embarking on a venture-capital search. Firms want to ensure that scientists are free to develop the discovery, and will need to determine whether the licensing of the technology is exclusive to one company, and for how long. When working with university-based scientists, the firm will also want to know whether the institute receives equity in the new company and whether the licence reverts back to the university if the start-up does not meet certain milestones or financial requirements.

A good technology-transfer office will employ business experts with experience in developing pitches and building management teams for start-ups. They can help in protecting discoveries, filing patent applications and outlining and resolving the researcher's licensing concerns.

But the challenges don't end there. Eva Harth, a chemist at Vanderbilt University in Nashville, Tennessee, who is trying to market a degradable nanosponge for the treatment of cancer and eye diseases, says that her search for the right firm to optimize her invention's commercial potential has been a struggle. “Getting from the science to putting it into the hands of physicians has been challenging, especially since I'm not an expert in business or finance,” says Harth. “If you don't have the connections and don't know how the system works, you're just lost.”

Venture collapse

Ellen Rudnick: "It's not just about money, it's about chemistry."

To get a handle on the current financial landscape, scientists need to understand the impact of the global economic crisis. The financial collapse of 2008 not only shrank the size and availability of investment capital, but also reduced the number of venture-capital firms. In the United States alone, the number dropped from 996 in 2007 to about 791 in 2010, and the threat of closures continues.

The largest impact on venture-backed companies may have come from the declining initial-public-offering market, says Emily Mendell, vice-president of communications for the National Venture Capital Association (NVCA) in Arlington, Virginia, the trade group for US venture-capital firms. Companies that had been in a position to go public were forced to wait, says Mendell, so firms had to invest more money and time than they had planned to keep promising companies afloat while the market righted itself. “There will be firms that will not be able to raise follow-on funds,” says Mendell. “We are seeing a shrinking industry going forward.” She notes, however, that the venture-capital industry in the United States, although smaller than it was, is not moribund. That was demonstrated in 2010, which saw the first year-on-year rise in investments since 2007. Venture-capital firms invested US$21.8 billion in 3,277 deals last year: a 19% boost in dollars compared with 2009 and a 12% increase in the number of deals, according to the 2010 MoneyTree Report by the NVCA and PricewaterhouseCoopers, a financial-services firm based in London.

Still, the current status of the industry helps to explain why many scientists feel that firms are increasingly reluctant to fund projects without a guaranteed return on their investment. “Venture implies that they take risk, but I think many of these firms take no risk at all,” says Harth. “They are looking for guarantees only.”

The United States and Europe are important centres for innovation and investment, and look set to remain so. But emerging markets are expected to drive the industry over the next five years, according to the 2010 Global Venture Capital Survey by the NVCA and Deloitte of New York. The survey, which measures the opinions of more than 500 venture capitalists worldwide, found that 92% in the United States think that the number of venture-capital firms in the country will decline in the next five years, a view echoed in France, Israel and the United Kingdom. Meanwhile, 99% of venture capitalists in China, 97% in Brazil and 85% in India expected to see an increase in numbers of local venture-capital firms.

The upshot: scientists in less-developed countries will probably see rising investment opportunities through private entities. But there are some caveats attached to the boom. Venture capitalists in emerging markets may be inexperienced — leaving scientists ceding control to firms not familiar with regulations — or ill-prepared to raise the large amounts of capital required for biotechnology and other health-related investments. With so much at stake, it is essential that scientists exercise due diligence in selecting a venture-capital firm.

Knocking on doors

Before selection begins, experts say, scientists should avoid trading away pieces of their company to less-experienced individual entrepreneurs and angel-fund investors for early investment funds before approaching venture-capital firms. If scientists have already signed binding agreements with other funders or licence holders, firms will see only unappealing prospects: limited profitability and months of legal negotiations. “The biggest mistake faculty members make is to partner with entrepreneurs who are not of the quality or experience that venture investors will accept,” says Nelsen. And it is often best to secure only the investment needed for the next 12–18 months, rather than seek funding for an extended period of time. To win more-substantial, long-term funding for a smaller, less-established company often means trading away more of the enterprise than it would once the company has recruited its first client or validated its first innovation.

Once that concern is dodged, the capital–start-up relationship must be considered. If it's akin to marriage, then the first step in establishing it is finding and courting a firm that fits the personality of the technology or discovery at the heart of the fledgling company. By studying a firm's track record, scientists can learn about the type of company that they support and the successes and failures they've had in the past. It helps to call a few colleagues or university entrepreneurship officers to gauge a firm's reputation among scientists in the field, because word travels fast about flawed and failing venture-capital firms.

More importantly, researchers should look for that vital link, person or connection that can open the door. Firms say that for every 100 proposals they receive from researchers and entrepreneurs, they will fund only a single start-up. Being taken seriously as a prospect often starts with a good reference from a colleague or department chair who has the credentials to attract high-powered investment. “In any university or national lab, find the person who has had success in creating a start-up, and they most likely can introduce you to someone,” says Nick Galakatos, managing director of Clarus Ventures in Cambridge, Massachusetts.

Once they have a foot in the door, researchers need to make a compelling case. They must explain what need their product fulfils, and how they intend to market and sell it. These preliminary conversations, which must be both aspirational and grounded in reality, help the firm to understand the level of risk involved in the prospective investment. They also provide early opportunities to assess the business acumen of the scientists on the project.

The best firms treat entrepreneurs as important customers and add tremendous value to a start-up in terms of recruiting, strategy, coaching and connections. But they are not doing so out of the goodness of their hearts, says serial entrepreneur Steve Blank, a lecturer in entrepreneurship at the University of California, Berkeley, and author of a blog for start-ups (http://steveblank.com). “Entrepreneurs need to understand that VCs are simply a sophisticated form of financial investors who in turn need to satisfy their own investors,” he wrote on his blog this year. Some investors acknowledge that there are bad actors in the field, who mistreat scientists and want to wrest companies away from their founders. But scientists' general lack of business experience makes them ill-suited to run multi-million-dollar companies in competitive environments for themselves. Furthermore, any firm willing to invest heavily in a start-up will expect to guide and manage that company's future.

Ultimately, scientists should take heart in the market forces that drive venture-capital firms. Those firms that fail to invest robustly in science, or that treat scientists unfairly, only damage their own reputations and undermine their own success. “Our business is to make people money, and that includes entrepreneurs and scientists,” says Nelsen. “If we make a huge company that is quite successful and the scientist doesn't make money, and the university doesn't make money, that's a huge failure for us. We want people to keep coming back to us again and again with their discoveries — so we all make money.”

n vitro assembly of cubic RNA-based scaffolds designed in silico

The organization of biological materials into versatile three-dimensional assemblies could be used to build multifunctional therapeutic scaffolds for use in nanomedicine. Here, we report a strategy to design three-dimensional nanoscale scaffolds that can be self-assembled from RNA with precise control over their shape, size and composition. These cubic nanoscaffolds are only ~13 nm in diameter and are composed of short oligonucleotides, making them amenable to chemical synthesis, point modifications and further functionalization. Nanocube assembly is verified by gel assays, dynamic light scattering and cryogenic electron microscopy. Formation of functional RNA nanocubes is also demonstrated by incorporation of a light-up fluorescent RNA aptamer that is optimally active only upon full RNA assembly. Moreover, we show that the RNA nanoscaffolds can self-assemble in isothermal conditions (37 °C) during in vitro transcription, which opens a route towards the construction of sensors, programmable packaging and cargo delivery systems for biomedical applications.

Nanoparticles boost cancer treatment

U.S. researchers say combining nanoparticles with a scorpion venom compound can cut the spread of cancerous brain tumor cells by 98 percent.

The University of Washington said the nanoparticles more than double the effectiveness of chlorotoxin, a small peptide isolated from scorpion venom.

"People talk about the treatment being more effective with nanoparticles but they don't know how much, maybe 5 percent or 10 percent," Miqin Zhang, professor of materials science and engineering, said Friday in a release. "This was quite a surprise to us."

Researchers said adding nanoparticles can improve a therapy by increasing the length of time the combination lasts in the body. Nanoparticles also boost effectiveness of treatment compounds because therapeutic molecules tend to clump around each nanoparticle, the report said.

Nanoparticles guide genes through the bloodstream

Scientists from University of Bonn in Germany have designed a technique that allows them to repair damaged arteries’ tissue. The technique is based on sending genes and healthy cells through the bloodstream to the place that needs to be repaired.


Earlier, the “problem” was that it was unknown what quantity of healthy cells to send in order to repair the tissue. Small magnetic nanoparticles which are situated on the planted gene or on the planted cell can with the aid of an external magnetic field be specifically directed to the location of the damage.

German researchers have discovered that the gene-based transfer is way more successful than non-gene-based one. Magnetic nanoparticles can support or even enable gene transfer under clinically relevant experimental conditions.

What is nanomedicine

Nanomedicine is a subfield of nanotechnology. It is often defined as the repair, construction and control of human biological systems using devices built upon nanotechnology standards. Basically, nanomedicine is the medical application of nanotechnology. Nanostructured materials, engineered enzymes and many other products of biotechnology will be very useful in the future. Of course, the full potential of nanomedicine is unlikely to arrive until after complex, high-sofisticated, medically programmable nanomachines and nanorobots are developed. When that happens, every medical doctor’s dream will become reality. Having robots fabricated to nanometer precision (1 nanometer = 1 bilionth of a meter) will allow medical doctors to approach the human body at the cellular and molecular levels. Interventions such as repairing damaged tissues (bone, muscle, nerve) will be possible.

We all know that the mankind is still fighting against many complex illnesses like cancer, multiple sclerosis, cardiovascular diseases, Alzheimer’s and Parkinson’s diseases, diabetes as well as some inflammatory or infectious diseases (i.e. HIV). Nanotechnology raises hopes and expectations for millions of patients that suffer from those diseases. For example, it is expected that doctors will be able to destroy the very first cancer cells and so stop the disease from growing.

Nanomedicine is a huge industry. Sales reached 6.8 billion dollars in 2004. Significant amounts of money are being invested in research – USA and European Union are investing billions of dollars and plan to invest more in the future.

NIH established eight nanomedicine development centers which are staffed by multidisciplinary research teams including biologists, physicians, mathematicians, engineers and computer scientists. The intial phase of their program is directed towards gathering extensive information about the properties of nanoscale biological elements. This is very important and will help scientists to correct defects in unhealthy cells. The second phase has been approved recently and is directed towards applying the knowledge from the first phase in treating diseases.

European Technology Platform is a platforum formed by 53 European stakeholders. Their first task the group had was to write a vision document on nanotechnology in which experts describe the extrapolation of needs until 2020.

There are three key priorities in the future: nanotechnology-based diagnostics and imaging, targeted drug delivery and release and regenerative medicine.

According to the journal „Nature Materials“, there are over 130 nanotech-based drugs and delivery systems developed worldwide. Nanomedicine industry is expected continue to grow and have a significant impact on the economy.

Colon cancer warning signs

A lot of patients suffering from colon cancer might well present no symptoms or signs during the earliest stages of the condition. When symptoms do eventually present, they can be many and varied, and can very much depend upon the size of the affliction, how far it has spread and also its actual location. It might be that some symptoms that present are as a result of a condition other than cancer itself, ranging from irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) and occasionally diverticulosis. Also, such problems as abdominal pain or swelling can be symptomatic of colon problems and may well require further investigation.

You may also notice that, upon going to the lavatory, you have some blood in your stools, and this can be a symptom of cancer. It can, however, also be indicative of other conditions and problems. For example, the kind of bright red blood that you may see on your toilet tissue could be as a result of hemorrhoids or anal fissures. It should also be remembered that various food items can also result in red-colored stools, and these include beetroot and red liquorice. Some medications can also be culprits, and some can also turn the stools black-including iron supplements. Irrespective, any sign of blood or change in your stools should prompt you to seek advice from your GP, as it is always best to be sure that it is not a sign of a more serious condition, and with any cancer,early detection and treatment is essential to a successful recovery.

You should also note-if you are currently concerned-any change in the regularity of your stools-including whether or not they are more thin or irregular than usual-especially over a period of several weeks. Also, be mindful if you have diarrhea for several days in a row or, conversely, constipation.

You might also experience pain in your lower abdomen-including a feeling of hardness. You may also experience persistent pain or discomfort in your abdominal region, and this can include wind and cramps. You may also get the sensation that, when evacuating your bowels, that the bowel doesn’t empty fully. Also, if you have an iron deficiency (or anemia), it may be an indication that there is bleeding in your colon. Also, as in most cases and types of cancer, you should seek medical advice immediately if you experience any sudden and unexpected or unexplained weight loss, as this is one of the principal red flags. Also be aware of more vague, seemingly incidental symptoms, such as fatigue. IF you have a couple of symptoms and also feel fatigued for days in a row inexplicably, then this is also another warning sign and you should seek medical advice. It is important not to panic, but just to be aware of what might be going on.

Remember, cases of colon cancer account for around 90% of all cases of intestinal cancers, and also account for more deaths every year of men and women from cancer. Early treatment is an absolute must.
